About the EASTWARD HO SR. 31
Appears similar to the DAIMYO from the same designers. First built of wood by International Marine Corp. of Japan.
The Eastward Ho SR. 31 is a classic 30.5 ft masthead sloop designed by Eldredge-McInnis and built by Portsmouth Yacht Co./C. E. Ryder (USA) in 1959. With a displacement of 11000.0 lb and a full/long keel, this vessel represents a traditional, heavy-displacement cruising design from the late 1950s.
- Best for:
- This boat is best suited for coastal cruisers and traditionalists who prioritize stability and comfort over high-speed performance, benefiting from its high comfort ratio of 31.25.
- Bluewater capability:
- With a low capsize ratio of 1.77 and a high displacement-to-length ratio of 355.23, the SR. 31 is well-suited for offshore passages, offering excellent stability and seakeeping characteristics typical of heavy, full-keel designs.
- Comparables:
- Comparable boats include other Eldredge-McInnis designs and contemporary full-keel sloops from the late 1950s, such as the Pearson 30 or early Cal 30, due to their similar displacement, beam, and traditional hull forms.
