Hey foils...the owner of that one posts here as "Slash" otherwise known to me as Wingnut. He needs a 5'10 to fit his bicycle trolly in which the board will cross the Nullabor. Hence the square nose. Its really a 6'6...
I just missed your prior post before doing mine...and the concept you suggest is ticking over. One could have detachable volume, swap the same volume section onto a different outline.
The idea of not having to make a whole board for every potential trial run of a different combination is pretty enticing.
With say, your hydro foil ply whatsits, have you found that the different rail types in your illustration make as much difference in a rail thats only plywood-thick?
I.e how much hold or release difference might be achieved in the 9mm roll space?

Theres so much in your post to comment...
The 5'10' thats really a 6'6", Im a fan of No Point boards..1/ the points dangerous and 2/ the front 6 inches has no function except for aesthetics.
The "Arch Bar" concept or a Multi Component board... its got to be the next step in refinement. Instead of ploughing away at foam blocks to sculpt the perfect sliver within... it would be easier to build up a board from specialised components. Decks and hulls have different performance needs, just make each piece from the best products and put them together.
And your comment ..."Preformed composite sheets milled to any custom dims, no glassing required, heat-set to a custom rocker, with molded float sections ready to add."..... Not just for experimental boards but for standard consumer boards, just use what other industries are doing. Its the next step to catch up to where modern manufacturing is.
With the ply foils Ive made I didnt find a great deal of difference in changing rail profiles, some diff.... but not a lot. I just completely abandoned rails and their hold/release like a redheaded stepson on a highway and once theyre not in the equation ,its one less thing to obsess over. Ultra slim rails already exist and work on kiteboards/ wakeboards/ skim boards/ paipos....
In 1975, if you brought out a 2010 pro board and gave it to the shapers back then, theyd scoff and say it cant work or even be ridden. Current boards are heading down to sub 1 inch anyway. Componentry and specialisation will happen, it makes manufacturing sense.
