Alain,

If a world cruising cat is your end desire, I would reconsider the building method. Farrier's F41 is not a wood boat, but a foam core boat. Farrier went this way because it saved so much time and weight over the wood designs he began with. If the Farrier boat is more of what you want, then consider a smaller foam core boat as a project, maybe the F22 trimaran. This is where I ended up when I was considering a cruising cat as a project when I retire. Just some food for thought.
