About the NELSON MAREK 43
(Masthead rig version shown here).
The Nelson Marek 43 is a rare, heavy-displacement cruising sloop designed by Nelson/Marek and built by Carroll Marine (USA) in 1993, with only 9 hulls constructed. Its substantial displacement of 16500.0 lb and high comfort ratio of 22.79 reflect a design prioritizing stability and seakeeping over speed.
- Best for:
- This boat is best suited for experienced coastal cruisers and those seeking a stable, comfortable platform for extended offshore passages, given its heavy displacement and proven bluewater pedigree.
- Bluewater capability:
- With a displacement of 16500.0 lb, a low capsize ratio of 1.97, and a fin keel with 8.92 ft max draft, the Nelson Marek 43 is well-regarded for offshore capability, though owners report critical structural concerns that must be verified.
- Comparables:
- Comparable boats include the Hallberg-Rassy 43 and the Tartan 4300, as they share similar heavy-displacement characteristics, fin keels, and a focus on safe, comfortable offshore cruising from the same era.
