I worked it out it looks alike one of those Meyhoffer thingies without the big cuts outs
Ours came first by at least a decade, but yes there are some similarities especially to the 'slip in'.
The second gun shape will have a slight incut near the tail also.
Mind sharing the theory on that...I would of thought that consistent rail line would off been the go rather than having a area where the water changes direction....especially on a big wave where you potentially have a lot of surface bump coming at you...I have really been that keen on flyers and bumps in the rails for that reason
It's foil theory... reduce the planshape curve and even reverse it slightly on the trailing part of the foil. This allows better flow mixing at the tail and a section of rail at the tail which is basically straight for precise control.
There's no bump or flyer involved.
Handling bumps and chop is one of the main reasons for the extreme pin displacement tail. When the planing area at the tail ios very low, with soft rails and plenty of thickness then the tail sinks controllably and in a self tending manner when the nose kicks upowards as it hits chop. This brings the pitch pivot fulcrum closer to the rider so the rider is at the 'neutral axis' and doesn't get jammed up and down as much when going over bumps and chop.Such tails handle chop way better than conventional planing tails, even the narrow ones.
The rails themselves have a constant section below the tuck... no changes or taper at all... that also gives a consistent response.
