The first proto is the second from right, its 7' 10" x 30.75". I had no idea how it would float me at 80kg so I made it full in nose, tail & rail.
As it turns out, it's too big, this was hard to imagine when planning the board but very true, it is more suited to my son who is big, 6' 4" & 93kg.
Being too big was evident in its turns they were flat, the board wouldnt roll & sink the tail & rail,
I fixed this in the second board it's spot on for my weight & style, there dosnt seem to be anything I can think of to improve it

You would have to be a sumo wrestler to want anthing over 33' !
It will still work, the trick is to pull the tail in & add vee to get that roll happening.
Also a deep concave under the front meter of board gets them really flying. I like to nose ride heaps, running up & down the board & stuff, I expected these boards to be useless in this department....but steping on the nose is like stepping on ice!!
Another factor to consider is the lack of rail you have to control compared to a 10' board, the smaller rail length can pull in tighter to the wave. And I think the most important & contraversal feature on the board is what produces the drive that develops the down the line speed.....a huge 11" single fin! Minimal drag & maximum stability, in both paddling/directional & balance, it dampens roll in rough water.
You realy have to ride these boards to fully understand their qualities.
The boards look quite stupid compared to what we are used to.
Anyone in my neighborhood is welcome to try one & see if it's their thing.
