I just spent the past two days shaping probably my most difficult shape yet, 7’0" x 17" x 21 5/8" x 14 3/8" x 3", inspired by everything I’ve read about Greenough, Simmons, Liddle, Gross, Krajkowski, Stubbies, Modified Displacement Hulls, and Swaylocks posts in the past. I’m calling it “The Freak of Laminar Flow”. The rail is high to low. The first 3rd is hulled on the nose belly, and severely scooped out (spoon style) into the middle 3rd s-arch-deck flowing back to the last 3rd turned down foiled out through the tail. I have several 15.1 megapixel pics, from my Canon T1i, but my laptop is too big a piece of crapola to even load one of them… maybe later from my computer at work.
I read on other posts about placing the box 9" up from the tail. Rusty Whitlock said 8", and Liddle say’s 11-14" or so from the tail block to the trailing edge of the flex fin. If I want the ultimate usage and optional movement of the 15" extra long box that I’m using in it, where should I place it in reference “up from the tail”, so I can ride it as a stubby/hull/whatever-you-wanna-call-it or a traditional single fin?
with that much box you could probably afford to put it in at 7 or 8" from the tail.however, it depends on how thin you made the tail-ie, is there enough foam that far back to allow the routing and placement of box…?
Here’s my buddy Brad Whann holding The Freak after Rusty Whitlock glassed it and I foiled a fin for it. I threw a 15" Bahne box in there from the old Aipa Stinger days (7" from tail) and placed the base of trailing edge of my flex fin at 14" from the tail (for now).
