About the CAL 36
Thanks to 'adelie' for providing correction.
Designed by C. William Lapworth and built by Jensen Marine (USA), the CAL 36 is a classic 1966-era cruising sloop with a production run of 1966. With a displacement of 11200.0 lb and a comfort ratio of 26.12, it offers a stable, heavy-displacement platform that prioritizes seakeeping over speed.
- Best for:
- This boat suits experienced coastal cruisers and bluewater adventurers who value a proven, heavy-displacement hull form and are prepared for significant mechanical and structural maintenance.
- Bluewater capability:
- With a capsize ratio of 1.85 and a displacement of 11200.0 lb, the CAL 36 is inherently stable and well-suited for offshore passages, provided critical structural integrity is maintained.
- Comparables:
- Comparable to other 1960s heavy-displacement fin-keel sloops like the Cal 40 or O'Day 36, these boats share similar beam-to-length ratios and interior volume, though the CAL 36's specific 10.33 ft beam and 27.0 ft LWL offer a distinct balance of stability and interior space.
