I am building a new boat, form the experiences learnt from the last 2 , Rock all Night( VOR 65) and Safran, IMOCA 60.
The Macif and Banque Populaire etc are actual sister ships o the Safran, but with refinements. My new boat will have the keel nd mast move aft, to make the boat more controllable at extreme winds.
My Safran, built 3 years ago, planes easily; but it is too beamy, and going up wind it tends to go sideways.
The RAN (VOR 65) has too much weight and mast forward, making sailing downwind at extreme wind speeds very touchy. But it s a great upwind boat.
So the new boat will take advantage of both.
