The Formosa 41 Ketch is one of William Garden’s enduring bluewater designs from the early years of Taiwanese production. Built for couples and small crews who value comfort more than speed, this 41footer combines a heavydisplacement hull, full keel, and split ketch rig. Garden, a prolific naval architect known for rugged workboats, drew a boat that prioritizes seaworthiness and longdistance voyaging over speed.

The Formosa Boat Building Company marketed the boat under the Clipper Marine brand as part of its Taiwan production line. Approximately 200 were built from 1971 through 1978, making the Formosa 41 one of the fleet’s most common models.

Design and Construction

Garden gave the Formosa 41 a heavy-displacement, full-keel hull with a canoe stern. Its teak-heavy construction helps evoke traditional clipper-ship aesthetics with a touch of luxury. These visual signatures place the boat firmly in the romantic tradition of 1970s Taiwan-built cruisers, although the canoe stern and teak-laden decks are not performance features.

The boat displaces 28,000 pounds and carries 9,200 pounds of iron ballast, for a ballast-to-displacement ratio of nearly 33 percent. Beam is 12.2 feet, draft is 6.16 feet, and the waterline measures 32 feet.

Rig and Handling

The ketch rig divides the sail area between the main and mizzen, providing a balanced sail plan and easier handling in heavy weather. That arrangement is well suited to couples or small crews managing the boat’s 780-square-foot total sail area. No single sail is unmanageably large for a two-person watch, while the mizzen’s independent sheeting provides useful balance downwind.

The mainsail measures 331.6 square feet and has a 43-foot luff. The mizzen adds 148.3 square feet, with a 29-foot luff. Forward of the mast, the Formosa 41 carries a 319.9-square-foot working jib and a genoa of 444.2 square feet. A 122.3-square-foot storm jib provides a reduced option for foul weather.

Accommodations and Character

The teak-heavy construction continues into an interior shaped by the boat’s clipper aesthetic. Together, its 41-foot overall length and 32-foot waterline give it proportions suited to voyaging.

Period descriptions present the canoe stern and extensive teak as luxury touches rather than purely functional cruising features. That character distinguishes the Formosa 41 from more spartan, workboat-derived contemporaries. Its small-crew orientation also reinforces its role as an ocean-going home for a couple rather than a charter platform.

Verdict

The Formosa 41 Ketch is a Garden-designed, Taiwan-built blue-water cruiser that trades outright speed for seaworthiness and long-distance comfort. Its full-keel hull, teak-rich character, split rig, and manageable individual sail areas make it particularly suitable for a couple. With approximately 200 built, it remains a reachable target on the used market.

Pros

  • Heavy-displacement, full-keel hull designed for seaworthiness and long-distance voyaging
  • Ketch rig divides the sail area for easier heavy-weather handling by a small crew
  • Canoe stern and teak-heavy construction provide classic clipper-style luxury
  • Around 200 examples were produced, making it a common model within the fleet

Cons

  • The design prioritizes passage-making over speed
  • Its 1970s Taiwanese construction brings a substantial teak-maintenance burden
