The best way is to remove the deck and all the internal furniture. Turn it upside down and take a mould of the external profile.separate this off and lay to one side.

Make up a mould of the internal profile in the same manner . lay to one side.polish the external profile mould so that it is cosmetically perfect, lay on the gelcoat and then a continuous series of high modulous carbon fibre tows say +5 degrees, -5 degrees, +45 degrees, - 45 degrees, -5 degrees and +5 degrees. Build each rib and stiffener the same with a nomex core, ditto Keel but double up on the skins

Then laser scan the profile of the internal profile and crossload this to a 5 axis milling machine and set it to rout the voids betweeen the fillers so it will exactly match the inside of the internal oulded skin you have made as well.

Replace the keel with depleted uranium so you can lower the c of g

Hopefully all this will enable you to eliminate that evil stuff known as wood.

I could probably do the job for you for a mere Ł5 million plus tooling and expenses.
