One rider's experience...
F-One Kite Ambassador and local Wadell (well known kite surfing spot near Santa Cruz) resident Brian Friedmann is fleeing the upcoming cold and often windless Pacific North West Coast and will be spending the winter in La Ventana, Baja Mexico. La Ventana is a fantastic destination in the winter, with strong daily thermal wind, great vibes, good food, and plenty of outdoor things to do. Brian recently started winging and he is telling us his progression from bigger board to smaller ones, including the rocket air surf, the F-One inflatable foilboard series. Not everybody are or will be able to ride very small boards (<50L) when winging, but that being said the smaller you can deal with, the more freedom you have, whether wing surfing or not. The Wing revolution is marching on and we are all having so much fun with it – Nico Ostermann, BAKS Distribution

Brian with the Rocket Air Surf / Swing 4.2 and Gravity 1800
Having recently taken to wingsurfing, I’ve been going through a similar learning curve as many who have posted their experiences on social media sites. You start with some variation of a beginner setup like a big board (F-One Rocket SUP 7’6” SUP 120L), big wing foil (F-One Gravity 1800 or 2200) and medium wing (F-One Swing 4.2) with a good amount of wind. So first time out, yes, the SUP was relatively easy to get up foiling on but I found it hard to manage overall.
Hauling it up the beach, getting through the surf and the sheer size of the board 7’6” made for a lot of forward weight that had to be counter balanced by the foil underneath the water making it almost a bit counterintuitive and constantly requiring small weight shifts to keep foiling. I’m around 165lbs, live in Santa Cruz, am a decent surfer, an average kite foiler and ok prone (surf) foiler so some of those background skills helped to get foiling quickly on the SUP. Although I was struggling with switching stance which kept me from making any huge gains back upwind. After making a few runs on the larger SUP board I wanted to try something closer to the other end of the spectrum, a 42L custom “sinker” that I used for surf foiling. After all, I’ve surfed forever, have reasonable prone surf skills and know how to kite foil fairly competently so how hard could it be? The answer, very frustrating. But like many of us I don’t give up easily so I made a commitment to keep going on the shorter board no matter what. I’d already swore to myself that I wouldn’t carry that behemoth SUP back upwind so I’m sticking to the smaller board until I get it nailed. A few days at my local beach and several long attempts made, I found myself struggling all the way down the beach (frequently cursing) until one moment just before giving up for the day a big puff pulled me up and I was going. Nirvana! A board that was short enough to turn, easier to make tacks on and had a couple good glides down some swells with the iconic finger dangle of the Swing in front of me. It felt so much better than being on that boat SUP. So the next few sessions were spent trying to reproduce that one amazing water start in order to get more of that adrenaline feeling of being free on the foil with just the Swing. My shins and legs bruised and physically tired each day from all the failed attempts I continued to keep at it and not give up. This sport is really addictive and it’s interesting the pains you’ll go through to get more foil time.
I tried another shorter board, the F-One Rocket Surf 5’0” at 35L that was a bit easier than the 42L custom I’d been using. It raised my water start success rate very slightly, maybe 20% of the time I’d get up and foiling. The biggest challenge was getting the board to rise enough to the surface from my knees in order to jump to my feet and start working the foil up. My Swing skills were good, I was getting a lot of pull and slowly making my way to the surface on my knees but frequently would just sink the board again as soon as I put a foot on the pad. Then after consulting with the Bay Area Kitesurf crew and looking through their inventory I spotted the F-One Rocket Surf Air. An inflatable that carries the same outline and template as the hard Rocket Surf board intended more for paddle/prone foiling but has the benefit of higher volume (75L) being an inflatable. This could work, a board that gives you more volume but still has a small outline, less (or no) swing weight up front and is easy to manage or at least won’t continue to bruise my legs up more than they already are. So with the 5’8” Rocket Air Surf under arm I hit the water and immediately found that the board floats me really well. Actually it sits just above the surface an inch or two when I’m sitting on it and at the surface when on my knees. This is the perfect starting point to begin the process of getting to my feet and bringing the foil up. Once up, the shorter size of the board was still rigid enough to work the foil without any porpoise feeling or too much flex on the deck. What I found is the inflatable has made it infinitely easier for me at this stage in my progression and turned around a 20% success rate of getting up foiling to a 90% success rate. The extra volume allows me to easily get it moving forward which helps to stabilize it and simply put my front foot up, then back, and one or two pumps and your foiling. And this is in very little wind (few caps) so it’s not a huge lift from the Swing overhead. I can almost just stand up from a full stop. When it’s windier the process just becomes quicker, easier and if real windy I’ll move down from the larger foil wing to a medium size one. Overall I’m really happy that I jumped on the Rocket Air Surf and it may not be my ultimate board once I get better but certainly has earned a spot in my equipment list for now.
First go with the rocket air surf at Wadell
The inflatable has host of benefits like the soft surface and no more bruises. Extra volume in a smaller outline makes it more maneuverable. Portability is great and when deflated the board rolls into a pack similar to a small kite. This allows you to take it anywhere, it travels easy with no baggage fees. The weight is a key benefit as lugging any board attached to a foil out of your car, up the beach, into a head wind, through the surf, wherever is a pain. This board weighs nothing so you’re really only carrying the foil wing weight for the most part. Floatation is fantastic so you can paddle it to get off the beach or when the wind dies and you’re a half mile offshore on a downwinder. The Price! It’s nearly ½ the cost of most hard boards out there. And the Rocket Air Surf is super versatile. It makes for a great board for kids and others to get on the water or is great behind a boat or jet ski for new riders who want to learn the foil aspect of wingsurfing.
Some other tips I’ve learned along the way, take to a flat water location with lots of downwind room initially. Fighting larger swell, kelp and surf upon entry/exit only adds to the challenges of getting going. You may not have a flat water spot around but if you do it should be your first choice until you get more proficient. Managing the wing(s) and board is all new and there’s a lot going on at this stage of learning. Make sure you have all your gear. Can’t tell you how many times I was missing a certain screw, grabbed the wrong foil, forgot the pump adapter, whatever.
Again, new sport, new equipment. Make sure you have everything. Wear the appropriate gear and hydrate. If you’re in cold water make sure you have a thick wetsuit. You’ll be in the water a lot more than usual when your kiting or doing whatever water sport you usually do. If you’re in warmer water you may want to shed a layer or use a thinner suit. The amount of energy output when your learning is significant. It’s easy to tire out quickly during this phase of the learning process. The sooner you can get up on the board and actually foil the longer your sessions will become. By the way, warmer water is always preferred! And don’t forget to hydrate. It’s a bit of a calorie burner in the beginning and your biceps will feel and show it.
If you’re new to wingsurfing with no background in foiling it may be easier to take each part separately. In other words, go get a foil board (Rocket Airs a great start) and a friend with a boat or ski and learn getting up on the foil in that controlled environment. It’s a fun day on the water with friends and everyone can give it a go. Then separately spend some time with the Swing or whatever brand wing you have. Learn to handle it on the beach competently making hand changes with minimal effort. Simulate what you would be doing in the water when you need to tack. As mentioned, there’s a lot going on the first couple times in the water so the more you’re comfortable with things on land the quicker you’ll be at progressing.
A foot note on equipment, F-One is coming out with the new Rocket Wing series of boards which are a hard board with more volume intended specifically for wingsurfing. I’m looking forward to giving one of these a go soon but still believe the Rocket Air Inflatable is a great option for learning with.
This new sport is changing quickly and part of that is sharing experiences. Hopefully this will help others expedite through some of the pain I experienced working towards the right setup early on and find a niche board offering that may be right for you. Stay Salty!
The Kiteboarder Magizine Interview....
DEVELOPMENT PROGRAM START, WHO WAS THE LEAD INSTIGATOR IN YOUR BRAND AND DESCRIBE YOUR EARLY EXPERIENCES WITH WINGSURFING DEVELOPMENT?
It all started back in November 2018 when company founder, Raphael Salles, decided to try this new sport. He called our designer Robert and asked him what he could design, then designed and ordered our first Swing prototype. As Raphael and equipment tester Micka were very busy developing the new Bandit, this prototype had traveled to Cabo Verde and Cape Town without being tested. On their last trip to Cabo Verde in February 2019, Raph finally put the Bandit testing on hold for a day in order to test the wing prototype. After that first session, interest in the wing escalated quickly and an intense testing process started. Raph and Robert built prototype after prototype, experimenting and testing many features before finding the excellently balanced wing that is the Swing. The team completely fell in love with the sport and immediately saw all the opportunities that it would offer. Testing it in many conditions, from gusty 45 knots in the south of France to 8 knots in a Mauritian lagoon, The Swing offers a whole new world full of riding possibilities.

This is part two in a three-part series on the experiences of a wingsurfers guide through progression. We had a bit of a break in the wind here in La Ventana allowing for some rest and reflection. As mentioned in part one , I started this winging journey recently and wanted to pass along some of the experiences as new people learn about this exciting sport. Now, with roughly a month of solid riding behind me there has been a lot that has been learned and still more to know. I’m spending this season in La Ventana, a well-known kiting destination that I’ve visited many times over the past 14 years. It’s the perfect learning grounds for wing surfing. Coming from a strong kite surf background and focused purely on wave riding, I’m excited how winging has transformed my perception of a place like La Ventana that has “no waves”. This is true, there is very little in the way of “surf” here but there’s a good amount of deep water swell. Swell that can be easily ridden with a foil and wing which has made La Ventana, do I dare say it, a “surf destination” when viewed through the lens of riding swell with a wing and foil. A quick recap of my progression which started with the 7’6” Rocket Sup by F-one, a 1800cm Gravity foil and 4.2M Swing kite. After a few sessions and frustration with the longer SUP I went towards the other end of the board size spectrum to a custom 41L board that I’d prone foiled. Then to a 35L F-One Rocket Surf model which was fun but very challenging to water start unless there was a lot of wind. Next the smaller 5’8” Rocket Air inflatable was used which was a great transitional board and now in the past week I’ve managed to get my hands on the new Rocket Wing board by F-One that’s just coming out. The Rocket Wing range have four models from a 5’0”x 22” at 60L up to a 5’10 x 25” at 90L. These boards are specifically targeted towards the need for a board that will float enough to get you up on a foil with your wing easily yet maintain good performance. The exact model I have is a Rocket Wing 5’4” x 22” at 60L and I weigh about 160lbs. For the level that I’m at right now, the Rocket Wing board has allowed me more time up on the foil and provided the necessary stability to continue improving my skills. It’s much easier to get up on than the 35L/40L boards I was riding and creates a more direct and aggressive feel with the foil than the Rocket Air SUP inflatable which was a great tool in my progression. Much more compact than the 7’6” SUP I started on, the Rocket Wing has way less swing weight and overall felt really controllable. Here’s some more detail on positive aspects of the Rocket Wing based on my experience with the board. The ease of use and overall general stability on a number of levels. First, just floating on the board seems easier with a slower rocking motion thanks to the width, thickness, volume and bottom shape of the board. It’s stable while sitting in the swell, preparing to get up. It’s stable with a knee start keeping both knees parallel and pointed towards the nose when getting to your feet. It’s stable with a front foot up while still on a back knee during the transition to your feet and then when bringing the board up onto foil is also more solid. Another positive attribute is the volume and proportional outline of the board. It maintains stability during touchdowns onto the surface of the water when the wind would lull and I was able to remain standing and could get going again on a foil during these lulls much more frequently. On previous boards, even the SUP I’d often fall off as there was either too much side to side resistance or not enough on a smaller sized board. Tacking and jibing were also easier on this board. To date I’d spent most my time riding strapless toe side one way and heel side the other, never switching my feet. The Rocket Wing’s wider outline helped to compensate for poor foot placement. After only a few attempts I was able to switch stance much more confidently and maintain a better (heel side) tack allowing me to point higher upwind. Switching stance back to toe side and downwind jibes were easier as well. Portability, the new handle is genius making it much easier to manage the board in and out of the water. Unloading the board from your vehicle is simplified with the designated handle to carry the board from. This is the normal way to carry the board now regardless if I have a foil mounted or not. It just works really well and is positioned perfectly to offset the weight of an attached foil but also feels great when carrying with no foil attached. Getting over whitewater is easier by turning the board upside down, paddling the board with foil in front of you and placing one hand in the handle (it’s on the bottom of the board) to guide the board. This works really well and you can literally steer the board with the handle as you paddle out. Even with a harness on with the spreader bar hook I found that positioning myself further back with the harness off the back (nose) of the board made getting out a snap and no more swinging foil of death in the air in front of you every time you hit a whitewater or go over a wave. Standard features on the entire Rocket Wing line are well thought out. The pads are super comfortable even after hours of riding. The twin track (4 bolt plate) system works effortlessly and accepts most foils. While being relatively thick to create volume, the board feels good under your arm and is really light for its size. It’s much easier to carry into the wind when on the beach or loading on a car than larger boards. I’m spending a ton more time up on the foil and getting up much easier as a result of the Rocket Wing design. My progress has come a long well over these few weeks and the Rocket Wing made much of it possible. I love to tinker with different size boards, foils and wings and in the last few sessions I opted to go back down to the 5’0” 35L Rocket Surf and found that I can now get up on it much quicker compared to my earlier struggles. As with many sports the more time, the more progression the more you can finesse things as you get better and that seems to be exactly the case when I tried the smaller boards once again. A few things I’ve learned along the way. Make your life easy with this new sport. There’s equipment out there that’s really well designed for winging. The sport in general is relatively new and personally I have tried dozens of combinations of boards, foils and wing sizes. Fortunately, I have access to a lot of equipment that most people don’t but even after all the trials and tribulations, it would have been easier to wait until gear like the Rocket Wing board was available. It’s suited exceptionally well for the average wing surfer. Whatever equipment you end up on, play with the settings and adjustments. Even very small adjustments like moving your foil forward or back a 1/16th of an inch can make a huge change. Once you find that optimal foil setting, mark it with a permanent pen. I mark my boards for different size foils as well. Try shifting your feet further up or back. One thing that I really focused on was to see how light of wind I could ride in. During these sessions I fine-tuned my foot placement and could eek out slightly more efficiency by bringing my back foot directly over the foil and moving my front foot just a hair further back. This is no white caps near glassy conditions. And in those sessions even the tiniest shift of weight will stop you from foiling. The time I spent fine tuning my stance really made a difference on my normal wind days and made me a more confident rider during lulls. Go out and have fun! As with anything there will be good days and bad days and wing surfing is no different. In the early stages of learning you will get worn out quickly with all the getting up on the board, falling and going again. Even if you’re a quick learner and master it day one, your arms and other muscles will get tired since they are not the same as the muscles used for kiting. There are weeks here when the wind simply doesn’t stop for days. If your addicted to this sport like me, that means two and sometimes three sessions a day or one really long one. After numerous days of continued sessions, you simply can’t maintain the same level as you can when well rested. Mistakes become more frequent, frustration grows and you don’t have nearly as much fun. So don’t forget to take a break, recharge and rejuvenate yourself in between sessions. Hopefully you are out there wing surfing and getting the most out of this great new sport and if not it’s certainly worthy of a go. Stay Salty!
The Right Board.
Now that I’ve progressed I do occasionally go back and forth between the sinker (Rocket Surf 5’0” 35L) and the rocket wing (Rocket Wing 5’4” 60L). But ultimately the Rocket Wing wins for the simple fact that gains in performance aren’t enough to outweigh ease of use. Ease of use being defined as getting on foil with the least amount of effort or energy exerted. Being able to get up on foil and not struggle with getting to your feet is super important. Your sessions become much more enjoyable when your spending most of your time on foil and not laboring over getting to your feet. Unless the conditions are really good it takes a lot of energy to get going on an undersized board which reduces your overall session time and often leaves you falling more because your tired. It’s also a disadvantage to be riding an oversized board with more surface area than necessary. The result can mean the bottom of the board sticking to the water when trying to get up on foil or having a “wheely” affect where the weight of the board is counter balancing the foil underneath you so you’re struggling to keep it on foil as the case with many of the larger sup style boards. Also, as you progress things like swing weight and surface area come into play when tacking for example where you want to minimize your outline as you are going directly into the wind during transitions. The Rocket Wing boards were designed specifically to address the need for volume and performance for our wingsurfing sport. They are extremely well balanced, buoyant and stable given their size and very forgiving once on foil. My experience was that once on foil, the Rocket Wing board allowed me to get away with many errors in foot placement after switching stance compared to smaller boards. It also allowed for much more ease in getting up than a lower volume board and provides far superior maneuverability compared to larger boards. Using the right size board can make a huge difference in your progress. In general, the recommendation for board sizes are as follows. For a beginner your weight (in kg) + 40 liters, for intermediates your weight in kg + 10L and for advanced riders your weight in kg -15L. Of course there are riders that may be much larger and need a high volume board and conversely riders that due to youth, fitness, expertise or sheer willpower can ride much smaller volume boards but these guidelines should cover the majority of riders.
Non equipment related topics that were useful to learn along the way. There are many ways to learn wingsurfing and these are things that were helpful to me. I’ll add the standard disclaimer to not hate me if you do it differently J. But before that, will make one more plug for an accessory. Use a harness line! The F-One Swing comes with pre-stitched webbing to easily add an inexpensive accessory harness line available from your dealer. This is super beneficial and will keep you from getting tired when going upwind so unless you plan on only doing downwind runs it’s an easy decision to get a harness line. As a side note, when you’re getting up the harness line can sometimes swing back and forth and hit you. One trick I learned was to use my index finger or thumb to grab the harness line where it attaches to the strut while holding the handles which takes the swinging out of the equation when starting off in the water to get up on foil. Once on foil it’s not really an issue. Also, don’t forget to try the different settings for harness line length. I preferred to have the harness line at the shortest setting (third knot) bringing the Swing in closer to my body for my shorter arm length and better control.
When you’re out on the water try and create the best possible outcome each time you prepare to get up on the foil. Get yourself mentally and logistically ready before every attempt to get foiling. As mentioned, more attempts to get up on foil equals less water time and getting tired much sooner. When you fly the wing on the beach it’s much different than in the water as everything is suddenly moving around and stability becomes a challenge. Depending on where you ride you may have gusty, shifting or inconsistent winds which can challenge your ability to get enough lift from the Swing or unexpectedly pull you off while in transition to your feet. Chop and swells can make balancing while still in the water on your knees very a rollercoaster ride as they lift the board from behind and the sides randomly. Kelp or seagrass can slow or stop you at any time if it wraps around the mast or foil. Here’s a sort of checklist of things that may help. Check to make sure your board leash is clear and not wrapped around your mast, stabilizer wing around an ankle or running between your legs. I attach my leash to the back of my harness to keep it away from my feet. It often ends up between your legs after a fall but is easy to clear. When you’re on your knees prior to getting up standing just lift the knee then ankle while pulling the leash gently back around your foot. Check the wrist leash is on and adjusted, keeping it loose enough to rotate on the wrist. You can get some more life out of your wrist leash if you spin it and unwind the leash where it attaches to the leading edge as it often winds and wraps tightly after several falls. Check around you and make certain no other kiters or obstacles are near before initiating getting to your feet. Look at your board positioning and make sure you start off at a downwind angle. This generally puts the swells behind you and makes it more stable since you’re not getting hit from the side with swell. Also, when starting on your knees, place them far apart which gives you more leverage to balance the board (or counter balance roll) while you’re getting in position to grab the handles on the wing. If it’s a light wind day look for upwind of you for signs of gusts coming and more wind. There’s no sense in trying to get up on foil if it’s light you just exert a ton of energy. Look upwind, read the water and watch when gusts are coming then get on your knees and go for it. Don’t hesitate to grab the handles! This is one of the things I see new people doing a lot. They become so fixed on trying to balance the board and spend too much time at this phase of getting up. As soon as you grab the wing handles everything becomes smoother as the foil stabilizes the board once a little speed is applied. When things start to stabilize put that front foot up, then the back and get to your feet. All of this should happen quickly when you’re learning. The worst thing that will happen is you will fall but at least you attempted to get up and you will still have energy to try again. Also for most people the first few sessions can be extremely frustrating.
You may already be a competent kite foiler or prone surf foiler, windsurfer or have no foiling experience at all but understand the basics. This is a new way to get foiling and the approach to get foiling is different than what you may be used to. The power you get from a kite doesn’t exists with a wing, or it does but you have to harness it in a much different way. Because there is no mast or lines you have unlimited directional capability with a wing which is good but can create problems during the early learning stages as you figure out the correct angles of attack for the wind and how to generate power. If your weight is off, the board with large foil under it may feel like it’s working against you as you try to balance yourself getting to your feet. This isn’t as prevalent in kite foils as they are much smaller in size. Just know that it gets easier quickly and it will take a little bit of time to figure out. Don’t get frustrated (easier said than done) and try to slow down once you get the basics of balancing on the board, holding the wing and going through the process of getting to your feet. When positioning the wing regardless of water starting or up on foil, keep that front arm (upwind arm) stiff at the elbow and high! This will help ensure you don’t dip a wingtip in the water causing the wing to immediately flip on its back. When the wind is light and up on your feet but not yet foiling, it will help to pump the board by applying back foot pressure as you pull in on the wing to engage the foil. In light conditions this can make all the difference in getting you actually up and foiling quickly. Once up on foil and stable, try to stand tall. This helps to get the most efficiency out of your foil and keeps your weight input even which is key when foiling. You may need to pay more attention to keeping your feet centered on the board (between the rails) than you would on a surfboard or other type board if you’ve not done much foiling. Once up try to relax and enjoy the ride!
Next steps, toeside and heelside tacking. Learning new things is always exciting and now that I’ve managed to get all the basics down (switching stance, getting up, heelside, toeside jibes, surfing swell, etc.) I’m focusing more on tacking lately. If you’re the kind of person who prefers to stay dry and not fall this isn’t the trick to learn. Progression can be satisfying although in my case the first toeside tack I tried I ended up putting the board on a rail while getting pulled backwards by the wing and I landed on my back, more specifically on my ribs and swore never to try it again. At 55 with not great medical insurance (yes I’m from the USA) getting injured or hurt is best to be avoided. One thing that really helped was to find a buddy around the same skill level to work on new tricks with. I was lucky enough to have a competitive friend visiting and she was game for learning the tack. My bruised ego from that first attempt healed quickly and we reviewed every Youtube video available on tacking a wing then went out each day and practiced until we couldn’t lift our wings over our heads. A few lessons learned are keep the wing high over your head and forward throughout the tack. A friend told me it’s like throwing a dart as you go into the wind on the transition. You could hear us yelling “dart, dart, dart!” every time we were in earshot of each other. It wasn’t long (a day or two) before we were successfully making a few tacks both heelside and toeside. It’s important to keep a lot of speed going into the transition to carry you all the way through the turn, at least while you’re learning. Often I’ll also look for a small swell to help lift the foil under me while heading directly into the wind at the apex of the turn. The heelside tack was definitely easier to consistently make for me as you can lean back keeping your weight and balance more consistent while doing the turn. On the toeside tack you really have to arch your back or figure or a way to keep your weight over the board at the apex of the turn in order to keep it coming around and maintain lift. Don’t get discouraged and once you’ve done a few, don’t overthink it. Like anything, with more practice comes consistency. When you start to really get the tacks down you’ll be less focused on the wind and very in tune with the foil making micro adjustments through the turns. Recently I created penalties so each time I fell I had to do three more attempts at the end of the session. I call these the Advil sessions. Also, attempting the tacks in unfavorable conditions like heavy gusts, very light winds, turbulent swells and overpowered definitely increased overall success rate.
Equipment maintenance is a necessity. My buddy Billy Ackerman is an accomplished kiteboarder in just about every discipline and great wingsurfer. He has a lot of gear and is an expert on maintaining it, more than anyone I know. So I was grateful to learn some tips from him on getting the most out of my setup. You spend a lot of money on your gear and keeping it in good shape will allow more time on the water and less time repairing things. Rinse your stuff off, at the beach if possible. Especially the foil after each use if it’s in salt water where corrosion can make screws almost impossible to remove. Once corrosion starts it continues to build and ultimately will make removing screws and metal fasteners impossible. Part of battling this is keeping the saltwater exposure to a minimum (rinsing gear). The other part is lubricating everything so that the corrosion can’t build up. Think of it more like maintaining a mountain bike where you need to lube things frequently. In the case of your foil, it’s probably worth the time to disassemble everything and lubricate all the screws at least once a week if you’re out there daily. I went out to the local hardware store and bought a simple $15 weed sprayer. Works great to rinse down gear and you also get the cheapest hot shower around if you leave it in the sun during your session. If you do get a screw that simply won’t come out, try letting it soak overnight in WD-40 or a dry lubricant. Also it helps if whatever tool your using to remove the screw with is made of a good solid material and not a cheap one which may bend, break or strip the screw head. One of the best things you can do to avoid the problem is lubricating everything with a marine grade lubricant like Lanocote or anti-seize. Here’s the one from Loc-Tite I use (thanks Billy) liberally to cover every screw on my foils with. If your board has a lot of volume it will most likely have a vent plug. Occasionally open the vent plug, turn the board upside down and bake it in the sun. This will help remove any water that may have gotten in the board if you accidently forgot to close the vent plug and hit the water. When you fold up your wing and put it away, try to get all the sand off of it and out of the bag. Unlike a kite, your wing will regularly come back to the beach soaking wet. In order to get all the sand and salt off the wing I usually temporarily roll it up and give it a good rinse when I get home. The nice thing about the wing is you can use the front handle to hang them to dry from a convenient location. Try not to leave your wing inflated on the beach all day or for excessive amounts of time. This just puts more UV stress on the material and like sand will reduce your wings lifespan. Try and keep your foils covered when not in use if you can. Carbon fiber and other materials used for your foil setup are fragile and can chip or scratch easily. Especially during transport where they are often thrown into the back of a car or placed in the dirt, asphalt or other rough surface.
Foil maintenance, sanding foils, makes a huge difference. I recently read an article which talked about the importance of keeping your foils maintained and smooth. My two primary Gravity foils were in pretty good condition overall but had a few small scratches and some wear at the tips of the wings. After reading the article I opted to wet sand them and it was easily noticeable how much better they felt in the water, a lot better. Basically you want to fill any major nicks or deep scratches with JB weld, slow cure as a first step. Next wet sand the areas that need it with 300 grit wet sand paper, then 600 and finally 1000 or more. This should be done on the wing, stabilizer and fuselage and mast if necessary although most issues are on the wing and stabilizer. It will remove that dreaded whistling sounds when foiling if it exists and you will definitely feel the difference on your foils. Be certain to use lots of water with the sand paper throughout the process. Once this is done bevel the trailing edge of the wing by taking a block and the 600 then 1000 grit paper to it. Start by squaring off the trailing edge at a 90 degree angle then rounding at about 30-45 degrees on the top side of the wing. There’s a bit of debate about finishing the trailing edges but I found this worked well for me. You don’t need to go crazy here and only want to knock down the edges. For the stabilizer, it’s the opposite, 30-45 degrees from the bottom side of the wing, slightly rounded. There’s lots more that you can do to fine tune your foils, here’s one YouTube video channel and there’s many more that talk about it.
