MARK 25

About the MARK 25

Eli Laminates was located on Long Island (NY). Motion Designs Ltd was formed after George Cuthbertson left C&C Designs in 1982. Thank you to JohnKelly Cuthbertson for the update.

The Mark 25 is a rare, lightweight fractional sloop designed by Motion Designs Limited and built by Ontario Yachts (CAN)/Eli Laminates (USA) during a single production year of 1984, with only 17 hulls constructed. Its compact dimensions and low displacement of 4130.0 lb reflect its origins as a trailerable coastal cruiser rather than a heavy offshore vessel.

Best for:

This boat suits active coastal cruisers and trailerable sailing enthusiasts who prioritize ease of transport and storage over heavy bluewater capability. Its light displacement and fractional rig make it particularly appealing to single-handers or couples seeking a manageable, responsive day-sailer for protected waters.

Bluewater capability:

With a low displacement of 4130.0 lb and a capsize ratio of 2.31, the Mark 25 is not well-suited for extended offshore passages due to its light weight and fin keel design. Its primary role is coastal cruising, where its agility is an asset, but its lack of heavy ballast and robust offshore construction limits its bluewater potential.

Comparables:

Comparable boats include the Catalina 25 and O'Day 25, which share similar LOA dimensions and target the same trailerable coastal market. However, the Mark 25 distinguishes itself with a significantly lower displacement and a fractional rig, offering different performance characteristics than the heavier, masthead-rigged alternatives.
