About the G&S 27
Similar to MARIAH 27. Designed to the MORC rule.
The G&S 27 is a 27.0 ft masthead sloop designed by Graham & Schlageter and built in 1986. With a displacement of 5100.0 lb and a beam of 9.0 ft, this vessel represents a specific era of American cruising yacht design, though exact build counts remain unverified in available data.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who prioritize a manageable size with adequate interior volume for short passages. Its moderate comfort ratio of 17.7 suggests it offers a relatively stable ride for its size, making it appropriate for protected waters and light offshore use.
- Bluewater capability:
- With a capsize ratio of 2.09 and a displacement of 5100.0 lb, the G&S 27 is generally considered suitable for coastal and nearshore cruising rather than extended bluewater passages. Its fin keel and moderate ballast ratio support stability in moderate conditions, but its age and limited offshore history suggest caution for open-ocean voyages.
- Comparables:
- Comparable vessels include the Cal 27 and O'Day 27, which share similar dimensions and target the same market of affordable, trailerable cruisers from the 1980s. These boats are comparable due to their similar LOA of 27.0 ft and focus on family-friendly coastal cruising rather than high-performance racing.
