About the CAPE DORY 300 MS

Sailpages Buyer's Take

The Cape Dory 300 MS is a classic, heavy-displacement cruising sloop designed by Clive M. Dent and built by Cape Dory Yachts (USA) between 1985 and 1990. With a production run of only 47 hulls, this model represents a rare, high-quality example of Cape Dory's reputation for robust construction and comfortable offshore performance.

Best for:
This boat is ideally suited for coastal and offshore cruisers who prioritize seakindliness and comfort over raw speed, making it an excellent choice for couples or small families seeking a reliable, low-maintenance vessel.
Bluewater capability:
With a displacement of 11500.0 lb, a low capsize ratio of 2.03, and a full/long keel, the 300 MS is inherently stable and well-suited for bluewater passages, offering excellent motion comfort in heavy seas.
Comparables:
Comparable vessels include the Cape Dory 30 (non-MS) and the Island Packet 32, as they share similar heavy displacement, full keel designs, and a focus on safe, comfortable cruising rather than racing performance.
