New lapstrake/Ineos inspired dw sled in the making. Also added more rocker and "only" 5'8"
Very cool!
ready for spartle and laminate. My calculations tell me it will be around 100+/-5 liters. Will aim for weight under 5kg!
I had one of these that released from the water well. Very unstable for the dimensions though. Yours will be a challenge, looks great

Woah havent seen this before:O Tails nearly identical. Think it will be plenty stable compared to the first original experiment I did.
Laminate:
Bottom 1x 160gr twill Carbon on bottom. 1x Biax 400gr carbon at the mount area
Top 1x 160gr twill carbon and double up at standing area.
Wanted some light uhmwpe/innegra/nylon at the rails but havent managed to find this..
Will give it an polyester based topcoat.
Core is 30kg/m3.
Had a few goes on the board already. Stability not bad, guess board is around 100ltr, touchdowns are silky smooth, no stick or steering. Easier takeoffs than the pintail! Volume distribution is even when standing in takeoff stance which is neat.Still need to take it for an proper DW though
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.
Great experimentation! There's been some chats on FB and other groups about bottom design lately, experimenting with vee ... I forgot about this thread.
I noticed yesterday my friend's Sunova Aviator Wing/Sup has vee.
A buddy is intrigued by this board: appletreesurfboards.com/product/pro-foil-surf-board-full-carbon/
Seems to be introduced 2 years ago but nearly no reviews online, flopped? Limited feedback is it does pop up quick but it tends to track uncomfortably on touchdowns. And also that it would benefit from some bevels/chines.
I am giving this a try on a board I am making, vee in the nose and slightly along rails, leading into a medium chine. Maybe best of both worlds? We'll see if a noticable impact. This board is also 2nd in the experiment of going shorter but thicker: 4.5 x 19 x 4.25. Aiming for the benefits of low swing weight but actually paddle-able by middle-aged mortals wearing 5mm wetsuits in varied (stormy) surface conditions.

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?
