P70 Motoryacht Delivered by Spirit Yachts Spirit Yachts recently delivered their motoryacht flagship, the 21.7-meter/71.6-foot P70. The yacht was built in wood largely and skimmed with a thin layer of epoxy resin. Constructed using Sapele ring frames to which Douglas fir longitudinal strips were bonded, the P70 build followed the same core processes of Spirit’s sailing yacht hulls. Once the initial structure was complete, diagonal layers of kaya wood planking were laid down, sanded and vacuum infused with a thin layer of epoxy resin. The method saves some weight compared to a similar sized vessel built of traditional GRP. Below is a launch photo by Waterlinemedia.
