The ETAP 39s, introduced in 1998 as the flagship of the Belgian shipyard’s fleet, remains one of the most technologically distinctive production cruisers of its era. Designed by J&J Design, the 39s was engineered around the "ship-in-ship" philosophy that defined the brand: a double-skinned GRP hull with the void between the inner and outer layers injected with closed-cell polyurethane foam. This construction provides approximately 100 cubic feet of buoyancy, rendering the vessel officially unsinkable even if both hulls are breached. Beyond the safety aspect, this foam core acts as exceptional thermal and acoustic insulation, effectively eliminating the condensation issues common in single-skin fiberglass yachts.
