About the MARIAH 30
MORC Racer. Also called the Andrews 30
The Mariah 30 is a 30.0 ft masthead sloop designed by Alan Andrews and built in 1991. With a displacement of 7000.0 lb and a comfort ratio of 17.61, it offers a balanced blend of performance and stability for its era.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize ease of handling and comfortable motion over heavy offshore endurance. Its moderate displacement and fin keel make it well-suited for active sailing in protected waters.
- Bluewater capability:
- With a capsize ratio of 2.18 and a D/L ratio of 181.33, the Mariah 30 is best suited for coastal cruising rather than extended bluewater passages. Its relatively light displacement and fin keel design prioritize performance in lighter winds over heavy-weather stability.
- Comparables:
- Comparable boats include the Catalina 30 and O'Day 302, which share similar dimensions and target the same market of affordable, easy-to-handle cruisers. These models are comparable due to their similar LOA, beam, and role as popular entry-level cruisers from the late 1980s and early 1990s.
