Initially, the frames were setup at 14mm centres, but corrected to 132mm centres. As there is a lot of curve in frames 12 onwards, the relatively stiff mdf panels wont fit past frame 10. Up to frame 10, the mdf patterns fit perfectly..

Panel Layup Discovery
My preferred technique for laying panels up inside a basket may need re-considering. The forced curves in the bow area result in a distorted chine line forward of station 16. This is not serious in a model, and partially solved with custom 'fairing frames' along the outside of the chine. But this would be very tedious in a full size boat. I wondered if this was just something that only happened in the model, but by luck I noticed an interesting comment in the "Building the PT Skiff" building manual, on page 37. "#2 panel has plenty of twist at the forward end .... a bowing out on the top edges forward of station 1 is a result" . So this is to be expected.With ~12mm bottom ply, this could be a major drama. Should I go with the more conservative hull on frames construction method ? I wonder. I also suspect that we should rout out 'slots' in the inside of the forward panels to provide ease of shaping.
