Her published design ratios place her firmly in the heavy-cruiser tradition. A displacement-length ratio of 289 puts her squarely among heavy cruisers, while a ballast ratio of 30 percent is higher than only about a fifth of comparable designs. Her length-to-beam ratio of 3.61 makes her slimmer than roughly two-thirds of similar sailboats, trading interior volume for a more directed, seakindly footprint offshore.
Design and Construction
The Transpac 49 has a solid fiberglass hull and a lead keel, a straightforward, repairable combination without the delamination concerns associated with cored hulls.
On paper, comfort under way is one of her defining qualities. Her Motion Comfort Ratio of 47.5 reportedly exceeds that of 92 percent of similar sailboat designs, a figure consistent with her heavy-cruiser displacement and moderate beam Motion Comfort Ratio of 47.5. A capsize screening value of 1.55 and theoretical hull speed of 8.5 knots complete the picture of a boat that is fundamentally stable and unhurried.
With about 592 square feet of wetted surface and an immersion rate near 1,916 pounds per inch, she sits heavily and changes trim slowly as loads change. Her draft varies from 6.0 to 6.3 feet depending on burden, keeping her out of all but major marinas.
Rig, Sailing Performance, and Handling
The Transpac 49 carries a ketch rig with 1,050 square feet of sail area. Dividing the sail plan between main and mizzen makes short-handed trimming easier and reduces the load carried by any single sail. It also demands less physical effort than handling one large mainsail on a 39,000-pound hull.
The scale of the running rigging reflects the loads involved: mainsheet travel is 122.5 feet, and the genoa sheets are 49 feet long, all using 5/8-inch line running-rigging dimensions. Her sail-area-displacement ratio of 13.69 is modest, confirming that she was built to carry her rig through weather rather than sprint in it.
The boat’s heavy displacement means she won’t accelerate quickly or point high in light air. These are characteristics rather than defects, and buyers should weigh them against the comfort and load-carrying ability provided by the same design.
Propulsion and Tankage
A 120-horsepower inboard diesel is the specified propulsion, with an optional 120-horsepower Ford Lehman diesel. Under power, the Ford Lehman gives a calculated maximum speed of about 7.9 knots—adequate for making harbor in an adverse wind, though motoring is never the boat’s natural element.
Tankage is generous by period standards. Published figures give fresh-water capacity as 399 US gallons, with another figure of 400 gallons also cited. Diesel capacity is listed as 150 US gallons, or a 568-liter fuel load. Together, those capacities support long independent passages and can make the boat self-sufficient for weeks 399 US gallons of water and 150 US gallons of diesel.
Refit and Ownership Considerations
Production began in 1976, creating a long build window during which systems and rigging have aged at different rates from hull to hull. Owners taking on a Transpac 49 should expect period-typical refit cycles for the 120-horsepower diesel, ketch rigging, and original tankage.
The solid fiberglass hull and lead keel provide forgiving substrates for repair. However, the boat’s mass and six-foot-plus draft make haulouts and storage more expensive than they would be for a lighter, shallower competitor. That draft also limits access to major marinas.
The Verdict
The Transpac 49 is a serious offshore ketch from the heavy-cruiser tradition. She’s stable, comfortable, and long-legged on tankage, but slow to accelerate and restricted by her draft.
Pros
- Motion Comfort Ratio exceeds that of 92 percent of similar designs
- Solid fiberglass hull and lead keel are straightforward to repair
- Generous 399-gallon water and 150-gallon fuel capacities
- Ketch rig divides sail loads for more manageable handling
Cons
- Six-foot-plus draft limits marina access
- Heavy displacement and modest SA/D ratio mean slow performance in light air
- Older hulls have aging systems that require refitting
