Bluewater Evidence · Ocean Proven

55% confidence

katamarans.com's independent review describes the Snowgoose 37 as 'a proven ocean crosser' with an 'unmatched track record' for bluewater cruising, stating hundreds have completed circumnavigations. No single named voyage with dates and crew is documented in current sources, so this is treated as strong pattern evidence of proven offshore capability rather than a single verified passage.

Overview

The Prout family had been building multihulls since the 1950s by the time the Snowgoose 37 arrived, an evolution of their earlier 34/35-footer lengthened into the model that became, by production numbers, one of the most successful cruising catamarans ever built. More than 500 hulls across all Snowgoose 37 iterations were completed before Prout & Sons ceased operations in 2002.

Design and Construction

At roughly 12,000 lb displacement on a 15.6 ft beam, the hull uses solid fiberglass construction, with more recent-production hulls solid below the waterline and cored above, and a solid bridgedeck for rigidity. The signature Prout mast-aft cutter rig, with a distinctive raked mast stepped well aft and a large genoa forward, was designed specifically to make the boat manageable for short-handed and singlehanded sailing, a genuinely different approach from most catamarans of the era.

Under Sail

Typical cruising speed runs 6 to 7 knots, with the design handling well on autopilot and performing capably in light air; 150 miles a day is realistically achievable. The mast-aft rig and large genoa make sail handling manageable shorthanded. The offshore record is the standout feature of this design: katamarans.com’s independent review calls it a proven ocean crosser with an unmatched track record, describing hundreds of completed circumnavigations across the model’s production run. Cruising World’s John Kretschmer notes that many 37s and all Elites were rigged with staysails, a big plus in heavy weather, and that the masthead-rigged 37 can be sailed like a monohull offshore without a huge roachy mainsail to wrestle in a storm. Practical Boat Owner’s Duncan Kent says she is not close-winded, with about 50 degrees off the apparent wind common, and fastest on a beam reach at 7 to 8 knots in a fresh breeze. The standard engine was centrally mounted with a steerable drive leg, which offsets the lack of prop wash over the rudders. The foredeck is solid rather than a trampoline, which adds strength and weight, and most boats have three double cabins.

Buyers Notes

Bridgedeck slamming on close reaches in rough weather is a known characteristic of this hull form; ask an owner about their real-world experience before buying. Salon headroom, around 5 ft 8 in, is low by modern standards. Confirm whether a specific hull is the original Snowgoose 37 (1983-1986) or the later, slightly wider Snowgoose 37 Elite (1986 onward), since the two have different displacement, sail area, and interior volume.

Known Issues

Bridgedeck clearancemoderatePassageBoats editorialAll years

Bridgedeck slamming in rough weather, particularly on close reaches, is a known characteristic of this design.

Inspection: Ask about the owner's experience with bridgedeck slamming in a seaway before buying, and factor point of sail into passage planning.

Salon headroomcosmeticPassageBoats editorialAll years

Salon headroom is limited, approximately 5 ft 8 in, noticeably low by modern catamaran standards.

Inspection: Check headroom in person if this matters for intended crew and use.

The owners describe the genoa and staysail on furlers, saying the small staysail adds about a knot of speed and that the two work well together when reaching.

The owners say the Yanmar 3GM has a lot of hours and is coming to the end of its usable life, and that the old saildrive needs some maintenance.

discusses

The owners say the boat surprised them under sail, having come from a monohull. They report comfortably holding 60 degrees to the wind and that "she feels a lot heavier than she's meant to".

Answering a viewer who has his heart set on a Prout Snow Goose 37 Elite: "I like Prouts, they're usually well built, they're old cats... it's basically like an older 80s cat design. They were a production company, so they're built a little bit better than a homebuilt plywood cat... these will hobby horse a little more than a newer cat. I would implore you to try to find an older Catana, I think it would be a better buy than this. The Prout Snow Goose 37 is 83,000, and you could probably find a Catana 410 that was one of the first Catanas."
