MONHEGAN 48

About the MONHEGAN 48

Also called SEGUIN 48.

The Monhegan 48 is a heavy-displacement cruising sloop designed by Craig Walters and built by Lyman Morse, with production records indicating a single build year of 1986. As a rare vessel with an unknown total hull count, it represents a specific era of American yacht building characterized by robust construction and conservative design ratios.

Best for:

This boat is best suited for experienced coastal cruisers and those seeking a stable, comfortable passage-making vessel, given its high comfort ratio of 32.42 and substantial displacement of 28100.0 lb. Its heavy ballast and full keel design prioritize safety and motion comfort over high-speed performance.

Bluewater capability:

With a low capsize ratio of 1.81 and a high displacement-to-length ratio of 237.88, the Monhegan 48 exhibits strong inherent stability and seaworthiness suitable for offshore passages. Its full/long keel and heavy ballast of 11998.7 lb contribute to a safe, albeit slower, passage-making profile.

Comparables:

Comparable vessels include other heavy-displacement American designs from the mid-1980s, such as the Island Packet 40 or older Cal 40s, due to similar emphasis on stability and coastal cruising capability. The Monhegan's unique full/long keel and high D/L ratio of 237.88 also align it with traditional bluewater trawler-yachts of the era.
