I'm BACK!
The boats in their bare form were a little flexible... actually they reminded me of a contortionist I saw in China, but that's OK they aren't finished.
Michael screwed the deck panels on temporarily, using a couple of gyprock screws in each corner, probably 6" apart, and the hulls are now so stiff they can be picked up by one corner and there is NO movement at all.
Every time he moved the boats (in my absence :rolleyes: ) he was frightened by/of the cracking sounds as the flexing put load on the epoxy joints, now they are quiet as little mice.
One thing he did was put a permanent (stainless steel) screw in the inside of the boat at both ends, holding the ends of the sheer clamp (the bit stuck on the top outside of the hull) to prevent a tearing failure at that point when the tops of the bulkheads were being bevelled.
The bare hull as shown weighs barely 10kg, and with all the remaining parts in it, we weighed it at 22kg. We expect that when finished it'll come in below 35kg which is a nice weight for two kids to carry on their own.
Onwards, ever onwards...
P (off with his beloved to get fish and chips for tea by the beach - Michael's coming too, but since he's a vegetarian, we're only getting him chips)
:D :D :D
