Andy I have only a couple of photos the one on page 8 showing the amount I removed and this one showing the car filler before I did bit more shaping, if you have looked at my Pelagic Trawler build it was basically the same method, i made some frames the shape that looked better then fitted them into the hull, I fitted a piece of ply down the centre of the hull to hold the frames in place then filled packed with close foam then shaped and covered with the car filler then lots of sanding, hope this explains.
