About the METALMAST 30
Originally called the CANNING 30. Racer/cruiser but aimed at the IOR 1/2 ton fleet of the time.
Designed by Peter Canning and built by Metal Mast Marine (USA) in 1979, the MetalMast 30 is a fractional sloop with a displacement of 6500.0 lb and a beam of 10.17 ft. While the exact hull count is unknown, owner reports highlight a strong community focus on maintenance, particularly regarding structural integrity and propulsion systems.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a stable, comfortable ride (Comfort ratio 17.85) and are willing to engage in proactive maintenance of the keel and rudder systems.
- Bluewater capability:
- With a Capsize ratio of 2.18 and a displacement of 6500.0 lb, the boat has moderate offshore potential, but its suitability for extended bluewater passages is contingent on verifying the structural integrity of the keel attachment and rudder stock.
- Comparables:
- Comparable to other late-1970s American fractional sloops like the Cal 30 or O'Day 30, the MetalMast 30 offers similar dimensions and a moderate D/L ratio of 216.61, appealing to those seeking a balance between performance and comfort.
