Roy Stewart's surfboard design innovations

We invented the parallel profile system of hollow wooden construction, and developed the tunnel fin independently, our many different tunnel fin setups are also unique.When the tunnel fin was first used it was not a success as it was not properly utilised or understood.The FP12 surfboard is also unlike any other longboard ever built.So here's a list of our innovations1) Invented the flexible parallel profile wooden construction system. ( 1994 )2) Pioneered the use of extremely wide longboards ( 26" to 27" plus ) long before the SUP craze ( 2002 )3) Pioneered the use of extremely thin flexible longboards ( Length to thickness ratios below 50/1 )4) Independently invented ( not the first to do so ) and developed th tunnel fin ( 1998 )5) Invented and used several multi finned systems based on the tunnel fin which had never been seen before6) Pioneered and developed the constant rail section7) Independently invented and devleoped the displacement tail ( some similarity to square railed sinker tails from the 1830's and 40's )8) Developed the spitfire elliptical planform fin ( surfboard application ) and the fisrt to use spitfire cutaway fins9) Developed the first ( and so far only ) modern olo surfboards, including much work on rockers for extremely long surfboards.10 ) Invented leading edge channels for tunnel fins. . . just for a start !:-) :-) :-) :-) :-) :-) :-) :-) :-) :-)
