Hull Form and Design Philosophy
The Cruiser 51 is built on a fiberglass fin-keel hull with a spade rudder, the configuration that has dominated performance-leaning production cruisers for decades. At just over 49 feet LOA on a 44-foot waterline, the hull carries a beam of nearly 15 feet — generous even for a modern cruiser of this length. That wide beam is the engine of Bavaria's interior volume promise, but it also informs the stability picture in ways prospective owners should understand. The capsize screening formula of 1.95 puts the boat just inside the threshold conventionally regarded as suitable for offshore passages, with a result below 2.0 indicating better suitability for ocean passages versus coastal cruising. A deep-keel option extends draft to 6.89 feet, lowering the center of gravity and sharpening upwind angles for owners who don't need the 6.07-foot standard keel.
Rig and Sail-Carrying Power
The boat carries a masthead sloop rig with a reported sail area of 1,371 square feet, a generous inventory for a hull displacing just under 28,000 pounds. The resulting sail area-to-displacement ratio of 24 sits well above the threshold of 20 associated with relatively high performance — meaningful for a cruiser of this weight class, and an indication that the boat will move respectably in the kind of moderate conditions that characterize Mediterranean and coastal passage-making. The displacement-to-length ratio of 144 places the hull firmly in the light displacement category below 200, reinforcing the picture of a boat that rewards sailing rather than motoring its way through calms. The ballast-to-displacement ratio of 33 percent is on the modest side — ratios of 40 or more are associated with stiffer, more powerful boats — which means crew should develop an attentive reefing habit in building breeze.
Motion and Offshore Comfort
Ted Brewer's comfort ratio of 26 places the Cruiser 51 in the coastal cruiser range of 20 to 30 rather than the moderate bluewater band above 30. That number is an honest reflection of the design trade-off Bavaria made: a wide, volume-maximizing hull provides exceptional livability at anchor and in calm passages but will produce livelier motion in open-ocean swell than heavier, narrower blue-water designs. The boat's theoretical hull speed of 8.9 knots is respectable, and in good breeze on flat water the boat will approach that number readily given its sail-area budget. Owners who intend offshore passages would do well to plan around favorable weather windows and acknowledge the comfort ratio for what it is.
Accommodations and Tankage
Bavaria engineered the Cruiser 51 for serious live-aboard and charter capability, and the water capacity of 198 gallons reflects that intent. Few production cruisers of this era matched that figure without additional tanks, and it translates to meaningful autonomy between marinas. The wide beam that moderates the comfort ratio pays direct dividends below: there is genuine standing room, wide settees, and separate cabin spaces that don't require crews to sleep in shifts. The boat was offered in multiple interior configurations to suit private bluewater crews and charter operators alike.
Power and Range Under Engine
The original auxiliary is a Volvo D3-75 diesel producing 75 horsepower, paired with an 84-gallon fuel tank. The D3-75 is a robust, well-supported engine that delivers adequate push for a hull of this displacement and has established a track record for reliability across a wide range of Bavaria and other production boats. At economical motoring speeds the fuel capacity provides meaningful range, though offshore passages in weak-wind seasons should account for the boat's thirst if the breeze fails for extended periods.
The Verdict
The Bavaria Cruiser 51 is a well-proportioned production cruiser that delivers its best when the wind is up and the destination is coastal rather than oceanic. The J&J hull is light and quick for its class, the rig carries meaningful power, and the interior volume is class-competitive. Buyers who accept its comfort-ratio positioning — coastal to semi-offshore rather than committed bluewater passage-maker — will find a boat that sails agreeably, lives well, and benefits from the wide Bavaria service network.
Pros
- Sail area-to-displacement ratio of 24 gives strong sailing performance for the weight class
- Light displacement hull rewards breeze and approaches hull speed readily
- Generous 198-gallon water tankage for extended cruising autonomy
- Capsize screening just below 2.0 is acceptable for offshore use
- Deep-keel option improves upwind performance and stability for passage-oriented owners
- Volvo D3-75 auxiliary is well-supported with broad parts availability
Cons
- Comfort ratio of 26 places this in the coastal cruiser band; motion in open-ocean swell will be lively
- Ballast-to-displacement ratio of 33 percent is modest; attentive reefing discipline is required
- Wide beam that enables the large interior also drives the comfort ratio lower than dedicated bluewater designs
- 84-gallon fuel capacity requires planning in light-wind seasons on extended passages
