I based the ship on the HMS Indefatiguable and on the most excellent pics at this site. Although the more I design it the closer it looks to the HMS Surprise/Rose

SkaforHire,
Yeah it may be more like a 24 pounder, which would be ok for the indefatiguaqble. It looks pretty good with a cre of three or four gathered around, I'll try to post some pics over the weekend.
Barry,
I love starwars lego. It seems to be the only way I can get imperial soldiers for my ship! *joke* Actually my kids seem to have "permanently borrowed" most of mine and have amassed a fair collection.
Phez,
The cannons are made of 5 of those roundy 2x2 pieces, 2 of those 1x2 bricks with a hole through it and one of those roundy cap things (real technical sounding eh?)
