About the CAL 34-III
These (CAL 2-34 CAL 34-III) later versions of the original CAL 34 share the same hull, but with a higher aspect rig. CAL 34-III, specifically, was promoted as more of a blue water cruiser than previous versions. A bridgedeck was added, with companionway offset to starboard. Most of the changes to the interior were also consistent with the theme of an offshore cruiser with additional wood trim. Among other changes: Fuel and water tank capacity was further increased. Heavier gauge standing rigging. Wheel steering is standard equipment.
Designed by C. William Lapworth and built by Jensen Marine (USA) from 1977–1979, the CAL 34-III is a robust cruising sloop with 193 hulls produced. Owner reports highlight its solid construction but flag critical maintenance needs, particularly regarding deck core integrity and engine exhaust systems.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a comfortable, stable platform with a 26.05 comfort ratio and are willing to perform diligent maintenance on aging systems.
- Bluewater capability:
- With a displacement of 10200.0 lb and a low capsize ratio of 1.85, the boat is capable of offshore passages, though potential keel cracking and rudder issues require careful verification before bluewater use.
- Comparables:
- Comparable to the Cal 34 II and early Cal 34 models due to shared design lineage and similar displacement, as well as the Pearson 303 for its era-appropriate cruising amenities and beam.
