I have just built myself a 9' 2" gun. Between AKU shaper and with some great input from DTM it came out pretty much how I pictured it. The final dimentions are:
9'2" x 27" x 4 1/2" thick. Volume was 116 liters before finishing and as I took a fair bit of foam out of the rails I am guessing the final volume is closer to 110-112. The board is designed for waves in the head high to 3 x times overhead range and more powerful reef break type conditions.
From the pics you will see that I moved the fins from their original position - which was way too far back and made the thing surf off the last couple of feet of rocker giving it very little drive. I moved all three of them almost 5 inches forward and it was a completely different board.
The first thing I notice riding it in head high waves is the way you can draw out a turn when necessary - but it can carve a very tight arc when required by planting the back foot - much more easily than my 8'9". The reduced area in the tail and very fine rails (at the tail) make it feel so responsive!! It also has a generous rocker. I need to test it in some good size stuff to really get the feel of it but so far so good.
Stability wise it is a bit wobbly at times with my 82 kegs on it, however she paddles very quickly so should be good for getting into em - which was the reason for keeping a bit of volume in her.
I tried to make it really strong and used 2x6 oz bottom with 2 x 6oz deck and a 4oz patch for 3/4 of the deck. There are now 6 plugs in it and even with a deck grip it still came in under 8kegs so I might have to chuck some lead weights on her for the really big stuff.
She should be a good Nor west WA board for our june trip I hope! A bigs thanks to DTM for his injput and the use of his mates shaping bay - and getting the foam sorted!!
Here are some dodgy pics:
