What this video covers
The RM 1180, a 40-foot performance cruiser designed by Marc Lombard and built in France, utilizes a hybrid construction method that combines marine-grade plywood with epoxy-glass composites.▶ 0:59 The hull bottom features a plywood-epoxy composite for impact resistance and structural stiffness, while the topsides use molded epoxy-glass to achieve complex, sculpted shapes.▶ 2:40 This design eliminates the need for heavy internal grid systems, resulting in a lighter, stiffer hull that reduces flexing during upwind sailing.▶ 3:15 The plywood core provides natural thermal insulation, which minimizes condensation and maintains interior temperatures in varying climates.▶ 3:53 Because the wood is fully encapsulated in epoxy and the hull is painted rather than gel-coated, the structure remains protected from rot and allows for straightforward repairs using widely available materials.▶ 5:17 The interior layout integrates structural bulkheads into a monocoque shell, prioritizing weight efficiency and performance over traditional luxury finishes.▶ 7:26
