About the IRWIN 33
Designed by Ted Irwin and built by Irwin Yachts (USA), the Irwin 33 is a classic 33.0 ft masthead sloop with a production run starting in 1974. With a displacement of 10950.0 lb and a beam of 11.17 ft, this vessel represents a substantial, heavy-displacement cruising platform from the mid-1970s.
- Best for:
- This boat is best suited for coastal and offshore cruisers who prioritize comfort and stability, as evidenced by the high frequency of dodger/cockpit canvas and bow thruster installations. Its heavy displacement and fin keel configuration appeal to those seeking a solid, motion-dampened ride rather than high-performance racing.
- Bluewater capability:
- With a displacement of 10950.0 lb and a capsize ratio of 2.02, the Irwin 33 demonstrates strong offshore stability and seaworthiness. Its heavy build and fin keel design support bluewater cruising, provided critical structural components are maintained.
- Comparables:
- Comparable boats include the Cal 34 and O'Day 36, which share similar displacement, beam, and production eras. These vessels are comparable due to their shared role as heavy, comfortable coastal cruisers with similar masthead sloop rigs and fin keels.
