Design and Construction
The Granada 375 is a fin-keel, spade-rudder monohull with a moderate-racer character. Its displacement-length ratio of 227 places it in that category. The 14,330-pound hull carries 5,511 pounds of lead ballast, giving a ballast ratio of 38 percent—higher than that of 42 percent of comparable designs.
The length-beam ratio is 3.14. A comparative assessment rates the boat as roomier than 62 percent of similar sailboats, and that breadth is reflected in its six-berth interior. Both the hull and deck are solid fiberglass; the known build records do not imply a cored hull or deck.
Rig and Sail Handling
The boat carries a masthead-sloop rig with generous line dimensions. The mainsail, genoa, and spinnaker halyards are each 110.1 feet long and half an inch in diameter. Jib and genoa sheets are 37.4 feet of 0.55-inch line, while the mainsheet is 93.5 feet in the same diameter.
The spinnaker sheet is 82.3 feet long. The cunningham measures 13.4 feet, while the kicking strap and clew outhaul are each 26.7 feet. These are robust dimensions for a 37-footer and imply a rig intended for period offshore and club-racing loads.
Performance Profile
With a sail-area-displacement ratio of 23.35 and a relative speed performance of 38, the Granada 375 is judged faster than 38 percent of its peers. Its displacement hull speed is 7.4 knots.
Under power, a single 28-horsepower Volvo Penta diesel gives a calculated maximum speed of about 5.7 knots. The wetted surface is approximately 409 square feet, while an immersion rate of 1,262 pounds per inch points to a reasonably stable load carrier.
The capsize screening value is 1.96. Its Motion Comfort Ratio is 25.0, which the survey comparison rates as more comfortable than 34 percent of similar designs.
Accommodations
The known layout provides six berths within the 11.9-foot beam. No further interior detail survives beyond the berth count and the comparative assessment of spaciousness. Any fuller picture of the arrangement therefore has to be inferred from the length-beam ratio and displacement rather than a documented plan.
Verdict
The Granada 375 is a late-1970s Danish design that balances moderate-racer numbers with cruising volume. Its lead-ballasted fin keel, solid-fiberglass construction, and full rigging schedule make it a credible used-classic candidate for sailors who value a known designer and straightforward construction.
Pros
- Rated roomier than 62 percent of similar designs by length-beam comparison
- A 38 percent lead-ballast ratio, higher than that of 42 percent of comparable designs
- Full masthead rig with heavy-duty halyard and sheet dimensions
Cons
- Motion Comfort Ratio rated more comfortable than only 34 percent of similar designs
- Relative speed performance rated faster than just 38 percent of its peers
