DECISION 4 & 5 PROGRAMS

TP52 and Carkeek 40

Spanning two generations of offshore raceboats, the Decision series embodied GPR’s technical precision and global coordination.


Decision 4 (TP52) underwent a complete structural overhaul and performance optimization, while Decision 5 (Carkeek 40) was designed and built as a next-generation race platform with Carkeek Design Partners.


The latter project required global logistics for manufacturing in China, transport through multiple ports, and completion in St. Martin—all under GPR’s supervision.


The program delivered multiple regatta wins, record-breaking offshore times, and set new standards in weight optimization and material performance.
