Wing Foil Board Volume - A deep dive into sinker boards

- čas přidán 26. 07. 2024
- This video aims to explain the differences between volume and floatation for wing foil sinker boards and how you can predict for a given volume how far you will sink on the water.
I also explain why the original technique of standing upright and sinking the board is a waste of energy, and cover how you can modify your technique to make this significantly easier.
Finally I briefly cover what you can expect with sinker boards when there is little or no wind and need to get back ashore

This is great. I am going to try my first sinker today🤞
I am 77 kg with wetsuit, harness, etc riding 84 liter board. Upon watching your video, I think my first sinker board will be around 65~70 liter in volume...Thank you !!❤
Good luck! If you have your knee starts down you should get used to it pretty quickly :)
Good topic and explanation but missing 2 factors: 1. the upward lift that the wing generates helps remove some of the rider weight. 2. the increased buoyancy of sea water also would amount to ~2L of volume for an 80L board. I'm 77kg and find on my 80L that i can float feet dry even in very light breeze on lakes, and of course more so on the sea, making it the sweet spot for a 1 board quiver.
Nice video Pete! Well put together! 🤙😎
interesting. thanx for sharing!
Nice one Pete some great tips 👍
Thank you!
g8 vid, thx!
Nice video! I use a 90l at 73kg naked.. I ride strapless in everything from very gusty marginal 7/8knots to 30knots with it. Id like to have a smaller more reactive board but im unsure I could get away with a smaller board.. hard to pull the trigger when they cost so much.
The market for second hand kit is getting more competitive as people move on to newer shinier kit, keep your eye out and i'm sure you can score a bargain :)
You ride strapless at 30 knxots ? 😮😮..Wow..that is a mad skill !! Whoa !!
Same for me (strapless, 73 kg, 80L board for everything). I've also had sinker boards, but they're annoying in gusty conditions. My solution was to invest in a lightweight custom board (4.7 kg for 80 litres). This gives me a more agile, lighter board than most standard sinker boards but with a comfortable volume.
Great vid. Would be helpful to touch on what start methods work best to beat the instability that can be frustrating when learning. Also, at what depth of knee riding is more stable vs more corky? I.e. my 60L for my 65kgs is very challenging in choppy conditions. My new 40L is most likely the replacement, with the 85L DW board for everything else.
Ooh that is a good question. I tend to get up and riding pretty quickly, avoiding any prolonged time bobbing around, plus you can get loads of stability from using your wing/dragging its tip in the water, which helps with buoyancy too. The rodeo stinkbug method is good for stability but i tend not to use it as i often have a 360 camera which would go into the canopy.
Nice vid Pete. I am about 88kg. I need 18kts+ to sink start my 39L. Knee starting is easier, but I would prefer to sink it. I can only get going if I can get the board to the surface. I was thinking 45L at my weight for prone (mid length) and wing to see if I can going in 15 kts. You think I could sink the 45? My daily driver is a 60L but I can’t sink it easily- too much instability at just below the surface.. thoughts?
I used to have a 65L and I found that a super nice board all round, never really had any corkiness problems with it even at my weight of 82kg. I think my technique must be different though. I try to avoid sink starting the board, it's just a waste of effort
Has anybody tried the classical Windsurfing waterstart when riding overpowered conditions? Setting the board 90°C to the water surface, foil mast horizontal, stepping into the foot straps before the foil sinks and using the power of the wing to start from this position directly without the board sinking?
There is a video or two on that if you do a search. If you do it without sinking the board you need a great deal of wind to pull you up onto it. The technique they have proposed is to sink the board to minimise how much wind it takes to get you over the board, but at that point your board is pretty sunken and then you gotta get it to the surface - which will take some effort.
I'm 83kg on a 36.9 litre learning to prone foil. OK size for me ?
I'm only learning to prone myself so not the best person to ask tbh. Seems a little on the small side for comfort, but you're probably a much better surfer than me 🤣🤙
