Hi Doug,
Walking around directly on the inside of the hull to be avoioded – unless the boat is afloat when there is a good solid mass of water on t’other side of the hull.
As to sole boards, I believe I’m correct in saying that originally, Faireys had a simple arrangement where 1/4 ” ply shaped sheets were laid on the stringers. This was reasonable when the surface was relatively flat but became an issue when the two dimensional curves became more pronounced as you went for’d. The sole boards were also prone to slide around in a seaway, just when you wanted a good firm surface on which to place your wellies. Many owners took to screwing the sole boards to the stringers, but all sorts of detritus and belly fluff accumulated inbetween the sole boards and the hull, which over time began to smell quite alarmingly.
Hope this helps!
Mike
