Well, while waiting for the paint to harden, I was attempting to shape the bulwarks with a heat gun and oh dear (or words to that effect) they twisted and basically fell apart.

Right then says I, lets move on to plan B...
First of all I suddenly realised that, while putting the carcase together, I had committed the no.1 sin - I hadn't waterproofed the flippin' thing on the inside !!!

At the same time I thought well, rather than make another attempt at the bulwarks, why not incorporate them into new skins for the hull...by that I mean - rub down the hull (yet again) and apply some thin ply 'on top' of the existing sides.
Hopefully that will work...
Meanwhile I still needed to get the inside of the boat waterproofed!
That would be no big deal except for the Bow area which was totally sealed up during the build.
Also, the lovely paint job on the deck would have to be lightly rubbed down and feathered in, otherwise there would be an obvious line 4mm in from the deck edges, which I had left in primer only.
Anyway, the deck was rubbed down first....
