The problem is how do you bend wood on a yet to built boat.
I am using wood 7mm thick and 50mm wide.


7mm is not thick, bending that in a simple curve will not be a problem.

50mm wide will be a different problem if the curves will compound ones - ie
bend in 3 axis. Usually that width will require soaking in water or steaming
to enable bending without splitting the wood.

The internal frame or the mould will enable you to bend the wood and clamp
or staple it in position.

For some good photos and an explanation of various strip methods have a look
