The 1979 Cal 39 was designed by Bill Lapworth / C. Raymond Hunt.

In terms of size, the 1990 Westerly Oceanquest measures 10.67m (35.0ft) overall with a beam of 3.40m, compared to the 1979 Cal 39 at 11.89m (39.0ft) with a 3.66m beam. The 1979 Cal 39 is 1.22m longer than the 1990 Westerly Oceanquest. The 1979 Cal 39 displaces approximately 38% more than its counterpart, which significantly affects how each boat handles in different sea states.

Looking at performance, the 1990 Westerly Oceanquest has modest sail power for its displacement with an SA/D ratio of 14.32 and 46.0 m² of sail area. The 1979 Cal 39, with an SA/D of 15.78 and 63.0 m² of canvas, offers moderate sail power suitable for relaxed cruising. The 1979 Cal 39 has the edge in terms of raw sailing performance.

For comfort and safety, the 1990 Westerly Oceanquest offers a moderate motion comfort level (comfort ratio: 20.1) and excellent capsize resistance suitable for offshore voyaging (capsize ratio: 0.75). The 1979 Cal 39 has a comfort ratio of 21.1 and a capsize screening value of 0.73. The ballast ratios are 38.5% for the 1990 Westerly Oceanquest and 41.7% for the 1979 Cal 39, reflecting their respective approaches to stability.

Below deck, the 1990 Westerly Oceanquest provides 7 berths in 2 cabins with 200L of water capacity and 100L of fuel. The 1979 Cal 39 offers 7 berths in 2 cabins with 200L water and 114L fuel capacity.

Verdict

For cruising: The 1979 Cal 39 is the better choice for comfortable cruising thanks to its higher comfort ratio, offering a gentler motion at sea that crews will appreciate on longer passages.

For racing: The 1979 Cal 39 has the performance advantage with its superior SA/D ratio, meaning more sail power relative to its displacement for competitive sailing.

For liveaboard: Both boats provide similar accommodation, making either a viable choice for living aboard. Consider water and fuel capacity for extended stays away from marinas.
