Lyman-Morse and Ray Hunt Design are teaming up on a new 70-foot exploration yacht aimed at owners who want to cover serious ground without giving up the ability to bring plenty of gear along. The Lyman-Morse 70 is designed around an experienced cruising couple, with a broad aft working deck sized for a 15-foot-5-inch RIB, aluminum skiff, kayaks or even a golf cart. Twin cranes handle launch and retrieval.

The interior keeps the cruising mission front and center, with a full-beam owner’s suite, separate heads, a forward VIP stateroom and convertible berths for additional guests. The galley gets dual refrigerator/freezers, a walk-in pantry and a dumbwaiter connecting it with the deckhouse.

Power comes from twin 1,136-horsepower Caterpillar C18 diesels driving through Twin Disc V-drives. Projected top speed is 28.5 knots, with a 25- to 26-knot cruise. With 2,465 gallons of fuel aboard, the Lyman-Morse 70 is intended for extended passages, and Lyman-Morse expects to launch the first hull in spring 2028.
