On the cover:  The 111′ (33.8m) Geist is the largest boat built to date at Spirit Yachts (Ipswich, U.K.). Her wood/composite hull, with some steel structural grid and frames visible here, is a testament to the strength and stiffness possible with Spirit’s choice of largely renewable and recyclable materials. The finished 59-ton yacht is powered by a 200-hp Torqeedo electric motor. Story on page 38. Photograph by Mike Bowden/Courtesy Spirit Yachts.
