I agree with tdw.
The Jouet could be ok but its IOR design is not the best for your purposes.
Trisfer - forget it.
CT41 - pretty boat with a wood deck and cabin that would get a no from me.
The Romaine looks interesting. Not an extreme design in any way I can see and looks good in the pictures. New engine (Beta) as well. This one would be my choice of any boat in this thread.
Living aboard in Victoria Harbour
