Design and Construction
Fabola AB laid up the Diva 45 in solid fiberglass, a straightforward hull build without a core, and married it to a fin keel and spade rudder. The ballast ratio comes in at 46 percent, a figure higher than 85 percent of comparable sailboat designs, and that significant lead low in the hull gives her a very high ability to resist heeling anchor. Her length-to-beam ratio of 3.25 places her interior among the roomier half, more spacious than 58 percent of similar designs, while a displacement-length ratio of 141 categorizes her among light racers, lighter than 90 percent of all similar designs. The immersion rate of about 1,614 pounds per inch speaks to a hull that loads predictably, and the wetted surface of roughly 559 square feet defines her hydrodynamic footprint.
Rig and Handling
The Diva 45 carries a fractional sloop rig and is slightly overrigged, bearing more sail plan than 62 percent of similar sailboats. With a reference sail her SA/D ratio is 22.7, rising to 26.3 with a 135 percent genoa, a spread of canvas that outperforms 98 percent of similar designs in light wind. The combined mainsail and jib area is about 880 square feet. Her motion comfort ratio of 21.2 is more comfortable than only 12 percent of similar designs, so the light-racer character is honestly bought with a firmer ride. The capsize screening value of 2.03 means she would not be accepted to participate in ocean races anchor, a hard limit on her intended envelope.
Accommodations
Bernt Lindquist's 3.25 length-beam ratio gives the Diva 45 a cabin plan that feels open relative to her peers, and the 46 percent ballast ratio's resistance to heeling keeps the interior steady when sailing. The boat's theoretical maximum hull speed is 8.1 knots, and under the optional Yanmar 4JHE diesel she calculates to about 7.6 knots maximum under power. With a draft of 7.7 to 8.0 feet dependent on load, she is a major-marina boat rather than a gunkholer.
Known Issues
The capsize screening value places the Diva 45 outside ocean-race acceptance, which is the one quantified safety limitation in the record.
The Verdict
The Diva 45 is a Lindquist-designed light racer with cruiser-scale volume, built in solid glass by Fabola AB. Her ballast-driven stiffness and overrigged fractional sail plan make her quick in light air, but the comfort ratio and capsize screen mark her as a coastal and moderate-weather performer rather than a bluewater contender.
Pros
- Ballast ratio of 46 percent gives exceptional resistance to heeling
- SA/D up to 26.3 makes her faster than 98 percent of similar boats in light wind
- Roomy relative to peers, more spacious than 58 percent of comparable designs
- Solid fiberglass hull and fin-keel/spade-rudder configuration
Cons
- Capsize screening value excludes her from ocean races
- Motion comfort ratio better than only 12 percent of similar designs
- Deep draft limits her to major marinas
