This device will be known as ' The Gob Stopper' we have done lots of boards at 27 wide and they go rail to rail just fine as long as the tail is fairly narrow and there's some curve in the tail planshape. Going 28.5" wide is new territory for us but should be sweet, the board will have a 10 inch tunnel or ' barrel' fin. I want something super skatey and fast which can carve tight arcs on flatter water, sort of an alaia/skimboard/Thrusterbuster mutation if that makes any sense. The first one's for my son James he's doing most of the build, I started building it and he immediately liked it and kind of took over ( that's how he gets a new board).
So far we have 3 of the 4 panels missed getting pics today as the light was too low, here's the planshape drawn, it doesn't really show much will post more pics of the actual components tomorrow.
The tail shape is a circular arc with the addition of a straight section behind the fin. . . there's a lot of curve in that tail so the last bit has a straight section to drive off, kind of like a fin section with a hollow trailing edge, it sort of looks like the planshape curve flares out slightly but really it's just a straight, this makes the squaretail an inch or so wider too.
The wide point is 30% back from the nose or 15 inches forward of the midpoint, lots of nose tweak and the tail is as flat as a pancake.
