IRWIN 33 MKII

About the IRWIN 33 MKII

Keel/cb: BU: 4.0' BD: 8.0'. Some were raced at the IOR 3/4 ton level.

The Irwin 33 MkII is a classic 33-foot masthead sloop designed by Ted Irwin and built by Irwin Yachts (USA) in 1976. With a displacement of 11950.0 lb and a beam of 11.17 ft, this vessel represents a specific snapshot of late-1970s American production, with the exact total hull count remaining unverified in current data.

Best for:

This boat is best suited for coastal cruisers and weekend sailors who prioritize a comfortable, stable ride over high-performance racing metrics. Its moderate sail area-to-displacement ratio of 15.02 suggests it is ideal for relaxed cruising rather than aggressive performance sailing.

Bluewater capability:

With a capsize ratio of 1.96 and a comfort ratio of 25.46, the Irwin 33 MkII demonstrates good stability and motion comfort for coastal and nearshore passages, though its single-year production run and specific build quality should be verified before attempting extended offshore voyages.

Comparables:

Comparable vessels include the Pearson 303 and the Cal 34, as they share similar displacement ranges and full-keel or modified fin configurations from the same era. These boats offer similar interior volumes and cruising comfort, making them direct competitors for buyers seeking a 30-33 foot trailerable or coastal cruiser.
