Profile Morse has HMS Kent plans, in various scales. Warship plans. Official page of publisher of PROFILE MORSKIE series
The wood is a bit bigger than you'll want to use for the ship itself... but you will need a box/crate for carrying it around to battles!
The way I do it is using the width of the frames drawing. Find what the scale width needs to be, divide it by the width of the frames and that give you the amount to scale it by.
for a full set of plans something I had done before, at a Kinkos I used to go to has a copyer that would copy full sheet plans for for say houses and such. I don't rember the size of the paper but it was LARGE tho and the paper in the machine was on a roll on the back side of the machine. run the legoned through key with the inch to feet key and use a ruller and take note of the legoned with the size meter to be come the size you need it to be then you run the hole set through then. you could shrink or blow a set of plans through the copy machine. hope if this helps. real life experiances hehe
