Lyman-Morse is building hull #3 of the Monhegan 42 semi-custom line. The Monhegan 42 is part of a successful collaboration between Lyman-Morse and C. Raymond Hunt & Associates. The hull shares Hunt’s legendary deep “V” design which ensures great performance while being extremely seaworthy.

Hull #3 will feature the Sedan configuration and will be powered by twin Cummins QSB 6.7’s (550 HP). The engines will be paired to traditional shafts and props in tunnels, which provides a shallow draft of just 3′.  

Options abound on this model, with four available configurations, including flybridge, extended cruiser, and open. As with everything Lyman-Morse does, classic boatbuilding and technology are intertwined in this model at every turn, including available cored SCRIMP hull construction, Humphrey Interceptor trim tabs, Side Power bow and stern thrusters, as well as varnished mahogany, 360-degree lines of sight, and much more.

Lyman-Morse Boatbuilding has a proven reputation for building incredible high-performing custom power boats designed by leading boat designers. One of the most successful partnerships has been with Peter Boyce of C. Raymond Hunt Associates with 16 very successful boats launched. From
this fleet, we selected the best features and proudly present the LM Monhegan 42.

The Monhegan 42 is a semi-custom build opportunity for owners demanding exceptional styling, a proven high-performing hull, power and interior layout options, in combination with our pre-engineered mechanical and electronics system standards, which result in a state-of-the-art boat that is absolutely one-of-a-kind and yet off-the-shelf reliable. With the performance characteristics of a luxury sports car, the Monhegan 42 is tremendously fun to helm while safe, comfortable and elegant making it the perfect semicustom boat choice and value in this size range.

Rough Water Confidence

With the famous Hunt deep-V bottom and twin engines, this will be an all-weather boat capable of handling any seas with the desired maneuverability required when the weather turns. Projected cruising speed exceeds 30 knots with two Twin Cummins QBS 6.7’s putting our 550HP each. The Monhegan 42 is built using the advanced SCRIMP ® infusion process and the hull is E-glass infused with vinylester resin. The boat is light with cored bulkheads and cored joinery work, resulting in good fuel economy.

Fit and Finish

The standard interiors are a combination of paint and varnished mahogany, giving the below
decks interior a traditional feeling but with plenty of space and light. With the Monhegan 42’s wide array of owner customization choices, each hull will truly reflect the owner’s personal style and be a proven performer.
