For me old mucker Barry...getting there now. Still not finished, but it's getting grottier and gungier by the day. Got the scum line to do next...for that, I put the boat into the internal domestic model boat ballasting and trimming facility (having first made sure that the good lady is well out of range), placing the boat into just enough water to reach the water line, then gently sprinkling a good amount of well powered chalk of several different colours (mainly white/green and pale blue) onto the water surface, and leaving it to sit for an hour or so. The chalk will oblige by sticking to the hull in the right place....then ever so carefully lifting the boat out and leaving it to dry naturally. Once dried, a few light coats of varnish sprayed very gently over the chalk line....gently so as not to disturb the chalk too much, and a nice scum line appears. (It's not my idea, I nicked it from David Merriman)
