    How to choose a Surf Foil Board ?

    What's different about a Surf Foil Board?

    Surf foilboards are smaller than your regular surfboards. They typically range between 3” and 6” foot. A foil specific SUP board may also have chimed rails to help you 'bounce' back up when you hit the water.

    The main function of the board is just to glide you into the waves. As soon as you get some speed, the foil will do it’s magic and lift you out of the water. That’s when you start flying. 

    With recent improvements, the Surf foil boards have become even easier to use. Often you just need a small wave to get some speed and then you'll be up and gliding. 

    How does the Foil work?

    The foil is made up of the mast and the foil or wings. The mast connects the board and foil. A short mast is easier to control and is the better choice in your early days. Once you got the hang of it, you can switch to a longer mast. Longer masts can handle more chop and offer more tolerance when carving and turning your board.

    The Foil has two wings. The front wing provides the uplift necessary to elevate you out of the water, while the back wing stabilizes your ride. The wing size varies by rider weight, surf height and conditions.


     Choosing a Surf Hydrofoil Choosing a surfboard foil can be a difficult decision. Luckily, we have the gear and knowledge to help anyone choose the gear that will expedite their progression. Some of the variables that may influence your choice of foils are weight, wave height, board choice, ability, and riding style. The path to choosing the best foil can be a convoluted one; as a result, we encourage new foilers to reach out to us for a personal recommendation.

    Slingshot makes 4 types of Surf Foilboards at the moment and can be defined easily by your skill level in the water and your weight. Bigger guys are going to need bigger boards. Whereas advanced surfers who already have a good paddle in fitness may be able to get away with a smaller volume board.

    We’re strong believers of that concept when it comes to learning how to SUP foil. Some things you just have to learn for yourself, like muscle memory, balance and weight distribution and how the foil feels and behaves as it flies through the water. Other lessons you’d be a lot better off learning from the mistakes of others; like the guy who spent a week failing because his stabilizer wing was upside down, or the many who tried to learn with a full-size mast instead of a short one.

    We’ve put together a list of five mistakes we see people make regularly when learning to foil surf. With a little effort and a bit of luck, you’ll avoid these mistakes yourself on your way to becoming a proficient foiler.

    5 FAILS:

    1. Improper foil assembly and maintenance
    It may seem obvious, but if you don’t put your foil together properly, it’s not going to perform properly. This means making sure all hardware is fully tightened, all components are oriented correctly and your foil is mounted in the proper position on the track (all the way back for beginners). Maintenance of your foil, especially if you’re in salt water, can not be understated. Rinse it well after each use, and disassemble and lube the hardware and connection points regularly.

    2. Foiling near others
    Foiling in the waves is still very new. It comes with its own unique set of risks, both to yourself and others, and it may not be accepted by other surfers at the beach. The great thing about foil surfing is it makes a cherry pie out of crappy conditions, so you don’t need to paddle into the lineup to have a blast. In fact, the last thing you want to do is try to paddle into a steep breaking wave. The waves you want are the crumbled whitewater you can ride all the way to shore. Stay away from others, stay safe and don’t give foiling a bad rap.

    3. Not enough front foot pressure
    This is probably the most common cause of crashing and frustration. You have to retrain your muscle memory when learning to foil. Too much back foot/heel edge pressure and you’ll rocket out of the water and crash. You want to pop up flat on the board, keep steady front foot pressure and slowly ease back when you’re ready to rise out of the water. Once you’re on-foil, you’ll build speed and generate lift, which makes proper front foot pressure even more important. The same goes for riding down the face of a wave- as the angle of the water changes, your front foot pressure must change to counterbalance.

    4. Starting with a full-size mast
    The short mast is one of the greatest learning tools in foiling. Slingshot’s Flight School mast package for the Hover Glide foil features 15”, 24” and 30” masts. This allows you to start small, get the hang of the foil with an easily manageable mast and progress in length as your skills evolve. The difference between starting with a 15” mast and a full-size mast is like night and day. For surfing, start with the 15” mast until you’re confident, then transition to the 24”. We’ve found that to be the sweet spot for tapping into the energy of the waves. If you’re towing into a large rolling swell, the longer 30” or 35” mast will give you more vertical range and allow for more speed.

    5. Kicking the foil under the water
    One of the most common injuries we see with foiling is from kicking the foil under the water. Event with bright colors, it’s easy to forget the foil is down there, and some parts of it are super sharp. Booties are a big help if you can stand wearing them, as is a full-length wetsuit that will protect you from the foil and help cushion the impact when you crash.

    If you’ve clicked through to this blog, we’ve got a pretty good idea that you know what’s coming. In short: FOIL MAINTENANCE IS IMPORTANT.

    That’s it! Just like a bike chain needs lube and your skis need a regular tune, your foil needs some lovin’. Though many treat it as a set-it-and-forget component, the nature of the materials in your foil leave them prone to nasty chemical reactions—and your hardware can get crusty. Nobody has time for that.

    For those interested in the cold, hard science of the thing (geeks unite!), read on below. For those itching to get back to foiling freedom, the main takeaway here:

    1. Loosen your bolts frequently—we’re talking after every ride if you’re sessioning in salt water. A simple turn or two and a light rinse with fresh water before re-tightening and storing will do the trick.
    2. A good coating of lanolin oil or marine grease on all areas of your foil and all hardware is a key detail and something that you should do after every few rides. Finally, wrapping your bolts with a layer of teflon tape helps prevent them from corrosion.
    3. Bonus points awarded if you stay completely away from sand and dirt while cleaning and maintaining your foil. That will radically prolong its life.

    And a quick video tip from our chief designer, Tony Logosz:



    It’s not simply the saltwater-meets-metal aspect that triggers the detrimental reaction in your foil. True, your problems are exponentially less pressing if you’re a freshwater foiler, but the two starring archenemies in this story: carbon and aluminum.

    Slingshot Foils are built with a combination of four main material components: an aluminum mast, carbon front and rear wings, fiberglass, and titanium screws. In our case, aluminum is one of the lightest, strongest materials possible and ideal to serve as masts for our foils for both optimal durability and price point.

    However, it’s also the instigator in the adverse reactions that screw up your getup. Saltwater acts as an electrolytic bridge between the wet, ignoble aluminum, thereby coaxing it into reacting with its neighboring carbon. Though we’ve thoroughly separated the two with a generous layer of “peacemaking” fiberglass, saltwater invariably travels up the threads in the titanium bolts (this is especially true if even the smallest grains of sand get stuck in the threads) and the crust begins to build. Once the aluminum and carbon are wedded, they don’t like to come apart. Over time, what you’re left with is a bolt that refuses to budge. And a prompt call to our customer service line.

    The good news: frequent loosening and flushing with freshwater slows this process nearly to a halt. If you keep up with it, chances are good that your foil will last for years of euphoric ocean sessions.
