One of the key factors contributing to the quality of the FRP laminate was the experience of the builder, CNB Marine, located in Bordeaux, France. It's a yard accustomed to high-end boatbuilding and one that's familiar with vacuum bagging and resin-infusion molding. Add to this its use of vinylester resin and a crew well trained to handle composite sandwich structures.
When it comes to building cruising boats with core material, resin infusion offers two big pluses. The first is a higher fiber-to-resin ratio, which yields a stronger, lighter, better-bonded composite structure. The second is in the way resin infusion fills the kerfs, or slots, between the checkerboardlike cuts in the core. With vacuum bonding, atmospheric pressure acts as a giant vise that forces resin into the core slots and eliminates future avenues for water ingress.
