About the COLUMBIA 45
Raised deck motor sailer was available in full keel and shoal draft versions. A ketch rig was also available. Same hull as the COLUMBIA 43. From builders original brochure.
Designed by William Tripp Jr. and built by Columbia Yachts (USA) from 1971–1976, the Columbia 45 is a substantial cruising sloop with 180 hulls produced. Its heavy displacement of 25000.0 lb and high comfort ratio of 36.09 reflect a design prioritizing seakeeping and stability over speed.
- Best for:
- This boat suits experienced coastal and offshore cruisers who value a solid, motion-dampened ride and are prepared for significant maintenance. It is well-suited for couples or families seeking a robust platform for extended voyages, provided they are diligent about structural upkeep.
- Bluewater capability:
- With a displacement of 25000.0 lb, a low capsize ratio of 1.69, and a fin keel, the Columbia 45 is inherently capable of offshore passage-making. However, its bluewater readiness is contingent on verifying the structural integrity of the keel attachment and rudder assembly.
- Comparables:
- Comparable boats include the Tartan 42 and O'Day 42, which share similar heavy-displacement characteristics and production eras. These vessels offer similar interior volume and cruising comfort, making them direct competitors for buyers seeking a 40-45 foot bluewater cruiser.
