Delta Marine is a Seattle-based yard founded in 1989, producing custom composite motor yachts for the American and international charter market. The yard composite construction delivers light, fuel-efficient hulls with wide-beam interior volumes suited to extended Caribbean charter programs, and the build quality holds reliably across multiple seasons of tropical operation. Three Delta Marine yachts charter in Puerto Rican waters, occupying the mid-tier of the Greater Antilles fleet where practical seakeeping, comfortable four to six stateroom layouts and a proven operational record are the primary charter criteria. Puerto Rico trade wind conditions from December to April suit Delta Marine hull performance: the protected waters east of Fajardo to Culebra and Vieques involve comfortable day passages, and the composite construction resists marine growth efficiently in tropical temperatures. Crews of six to ten manage daily operations, drawing on Puerto del Rey marina for provisioning and on the local markets of Old San Juan and Fajardo for fresh ingredients. Weekly charter rates for Delta Marine yachts in Puerto Rico run from approximately 55,000 to 140,000 euros per week, with the advance provisioning allowance of around 30 percent covering fuel, food, dockage and drinks. High season aligns with the Greater Antilles winter sailing season, December through April. Puerto Rico strategic position within the Caribbean makes it an effective base for a Delta Marine itinerary that can extend south to the Virgin Islands or north toward the Turks and Caicos if the charter group seeks more range than the Puerto Rico island circuit provides.
