Blue Fin 54

Sam designs in groups in his ongoing quest for unbelievable flexibility in boat design. The Blue Fin 54 is an adaption of the Blue Fin 48, which you should check out for the thought process behind her design. In the 54 variant, you keep the stunning efficiency and add more space and comfort, while keeping the fuel economy and designed-in ability to smooth out choppy waters. Sam has designed a single and twin screw version. The twin screw version offers a bit more performance and the ability to use the twin configuration for maneuverability in tight situations. The single screw version offers amazing efficiency for going the distance with minimal fuel burn. Our friend Temur Rukhaya has not only completed a sterling build of this design, he has given us real world data on the outcome of fuel efficiency. Read about Temur’s build here.
