About the COLUMBIA 34 MK II
Keel/CB and shoal draft versions were also available.
Designed by William Tripp Jr. and built by Columbia Yachts (USA) from 1970–1975, the Columbia 34 Mk II is a classic cruising sloop with 352 hulls produced. It is widely recognized for its robust construction and comfortable interior, though owners frequently report structural concerns regarding the keel and deck.
- Best for:
- This boat is best suited for coastal and nearshore cruisers who prioritize comfort and interior volume over high-performance racing. Its moderate sail area-to-displacement ratio and heavy displacement make it ideal for relaxed, safe passage-making rather than aggressive performance sailing.
- Bluewater capability:
- With a displacement of 12000.0 lb and a capsize ratio of 1.75, the Columbia 34 Mk II possesses the stability and motion characteristics suitable for offshore cruising, provided the keel attachment and deck core are structurally sound.
- Comparables:
- Comparable boats from this era include the Cal 34 and O'Day 36, which share similar displacement, beam, and interior layouts. These vessels are comparable because they all represent the late-60s/early-70s trend of heavy-displacement, fin-keel cruising sloops designed for family comfort.
