New lapstrake/Ineos inspired dw sled in the making. Also added more rocker and "only" 5'8"

ready for spartle and laminate. My calculations tell me it will be around 100+/-5 liters. Will aim for weight under 5kg!

Wow, great work!
What density eps and what layup scedule do you have planned?

Far out now that's a machine, keep us posted

it looks very narrow!

25" wide 5.8" at thickest

The pic is the highroller but I had the outwit same colours and design just a sup.

I like this a lot. And your process was great, go extreme to prove the concept then back off to make it more user friendly, like a concept car.

I've got soft edges up front and hard edges all around the back on my next wing board. The hard release seems necessary. I didn't do the bustle myself as by the time you are close to takeoff the board's wetted surface should be low but I'm curious to see how yours works.

The thing to film and test is if the board planes on that small section before liftoff. If not, then you might be able to simplify the tail. Many experts note that the foil should lift off before the board planes so all we are looking for is low speed acceleration up to where the foil lifts. That said, if your foil has a higher lift off speed, then your board might approach planing speed so as always it's dependent on the rider and foil, the whole system.

Loving this thread. Thank you for sharing.

thanks for the compliments.
Agree on the foil lifting before planning-speeds. My idea with the small surfaces and hard edges in the last 1/3 of the board was to give better run-off for the water. Both when taking off and touching down at high speeds. Also - I wanted a wide tail for stability and also a balanced volume distribution. So the lapstreak-design was the happy medium to try to achieve all this.

Too cold up here to juggle around with cameras while doing downwinders in the moment. But yes, need to do some filming once spring arrives

I have heard the same when it comes to the appletree board. A buddy of mine has is and even though he is really skilled he has a hard time on it. The large flat Vee will suck to the water if touching down at the slightest angle. You also remove a lot of strength/stifness and volume when doing the flat vee instead of slightly rounded vee.

Keep us posted on that board you are doing! Im not on either Facebook or IG so my inspiration solely depending on this forum:D

I will post some pics soon. re: flat vee vs rounded vee -- an interesting design choice on that Sunova Aviator, it has strong vee and chines, but both the vee section and the chines have concave in them. I am considering doing the same -- maybe just in the vee section, as my chines are fairly narrow. What will this do? I have no idea, just looks tricked out, haha. Prpmote earlier lift maybe?
