Mariner sailboats: one name claimed by at least five unrelated builders
"Mariner" on a sailboat's transom does not point to one company -- it is a name that at least five separate builders across Japan, the United States, and Britain reached for independently, sharing nothing but the word itself. The two best-documented lineages are Far East Yachts' Japanese-built ketches and the O'Day-descended Mariner 19, an American daysailer/cruiser with its own long chain of ownership; a third grounded lineage traces to a short-lived New Hampshire yard's Mariner 39, commissioned for charter duty. A British Mariner 17 and a thinly documented Rhode Island-built Mariner 28 round out the picture.
Origins and ownership
Clair Oberly founded Far East Yachts in Yokosuka, Japan -- the owners association's own site originally dated the founding to 1957, though a later, more detailed timeline built from correspondence with the yard's former chief engineer and the Kuroshio Yacht Club's founder revised that to 1958, so the year is best read as 1957 or 1958 per the association's own accounts. Oberly's yard started with the Herreshoff 28, then built the wooden Mariner 31 and 40 by 1960 alongside a Sparkman & Stephens 40, and introduced a separate wooden Mariner 35 in 1964 -- a different boat from the later fiberglass Mariner 35 built in New Hampshire. Fiberglass production of the Mariner Ketch line began with the 31 in 1968, followed by the 32, 36, and 40; the 32 and the Fuji 32 came off the same hull mold, though Fuji fitted an Alden-derived deck. When the yen's depreciation ended Far East Yachts, Oberly moved operations to Long Beach, California as Clair Yachts, then formed Clair & Kato Yachts in 1972 with Takuji Kato of the Tokiwa Group. When that partnership folded, Oberly took the 36 and 31/32 molds to California and let Taiwan's Tayana yard buy the 36 mold, producing the Tayana Mariner 36; Tayana also built a handful of Mariner 40s. A separate operation -- Bill Hardin working with Okamoto Shipyard, later Tokyo Yachts -- built 35- and 40-foot ketches designed by Bill Garden in Japan, unrelated to Oberly's Mariner 36 and 40.
The O'Day Mariner 19 traces to World War II: the Allied Aviation Corp. of Cockeysville, Maryland, which manufactured laminated-plywood aircraft fuselage sections during the war, commissioned New York designer Philip Rhodes to draw a 19-foot laminated-plywood centerboard sloop it called the Hurricane as part of a peacetime pivot into boatbuilding. New Bedford builder Palmer Scott bought a number of the resulting hull shells for the Southern Massachusetts Yacht Racing Association's one-design class, and Marscot Plastics Co. converted the design to fiberglass before George O'Day struck an agreement with Rhodes to market it as the Rhodes 19 -- fifty of which sold in 1959. In 1963 O'Day built the first Mariner, a cabin, family version of the Rhodes 19 and the company's first entry into the cruising-boat market; ninety-two sold that first year, and a National Mariner Class Association formed in 1966. O'Day discontinued the Mariner in 1979, after 3,771 boats, to focus on larger cruising designs. Rebel Industries' Spindrift One Designs picked up the molds in 1980, starting at hull No. 4000 and building 78 boats before Stuart Scharaga became the new builder in 1982 as Stuart Marine Inc. of Rockland, Maine; David Whittier took ownership of Stuart Marine in 1984.
A third American lineage begins in 1980, when Moorings founder Charlie Carey commissioned the Mariner Yacht Company of Rochester, New Hampshire, for a bareboat-charter design; the result, after lengthy discussions with Carey, was the Mariner 39, designed by Eric White and Arthur Berry. Only 29 were built before the company folded, more than half carrying the Moorings' charter layout. Catalog records also list a Mariner 35, credited to Holman & Pye, and a Mariner 48, credited to George Stadel III; whether either came from the same builder is unconfirmed.
Two further lineages stand apart entirely. In Britain, Peter Milne designed the Mariner 17, built by Richmond Marine -- a boat with no tie to either the Japanese ketches or the O'Day daysailer. And catalog records credit a Mariner 28, built in East Greenwich, Rhode Island by Mariner Yacht Co. from 1977 to 1983 with roughly 150 to 200 hulls produced, as its own distinct, thinly documented American production run.
Construction through the eras
Good Old Boat's account of the Mariner 36 called the Far East Yachts ketches, plainly, "heavy, solid yachts" -- the 31 and 32, built from the same mold, carried fiberglass hulls with full, long keels, though the 32 alone carried a wood deck. The O'Day Mariner simplified the Rhodes 19's Lightning-style double-spreader rig to a single spreader, and offered a cast-iron centerboard that, over time, outsold the fixed-keel version. Rochester's Mariner 39 was built to a heavier standard still: a solid-fiberglass hull three inches thick at the turn of the bilge, external lead ballast fastened with Aquamet stainless-steel keel bolts, a balsa-cored deck backed with solid fiberglass under the hardware, and a hull/deck joint through-bolted every four inches. The Rhode Island-built Mariner 28, per catalog records, used heavy-displacement fiberglass construction with a long encapsulated keel.
Lines and generations
The Mariner Ketch line's clearest legacy is continuity through ownership changes rather than a single generational handoff: the fiberglass 36 that Far East Yachts introduced in 1968 outlived the yard itself, resurfacing years later as the Tayana Mariner 36 once Taiwan's Tayana yard bought the mold -- one of the more collectible rebadges to come out of the Oberly lineage, and a reminder that a boat sold as a Mariner 36 may be either build.
Who Mariner is for
There is no single "Mariner buyer," because there is no single Mariner. Someone after a solidly built Japanese ketch, wood or fiberglass, is shopping the Far East Yachts/Clair Oberly lineage, including its Tayana-badged 36. Someone after an approachable, well-documented small cruiser wants the O'Day-descended Mariner 19, traceable in an unbroken chain from the Rhodes 19 through Spindrift to Stuart Marine. A buyer drawn to a charter-tested cruising boat should look at the Rochester, New Hampshire-built Mariner 39, while the British Mariner 17 and the Rhode Island Mariner 28 are smaller, more isolated finds each requiring their own separate research. Confirming which builder produced a given listing is the necessary first step before anything else about it can be trusted.
