Design and Construction
The Tiburon 36's hull is solid fiberglass, laid up without a core, and mated to a solid fiberglass deck. Beneath the waterline she draws between 4.99 and 5.29 feet depending on load, a depth that keeps her out of the shallowest anchorages but lets her slip into most marinas without drama. The long keel gives her the directional stability and grounding tolerance one expects of a bluewater cruiser rather than a fin-keel weekend boat. With a displacement of 21,000 pounds and 7,000 pounds of iron ballast, the boat sits at a ballast ratio of 33 percent — a figure higher than only 15 percent of similar sailboat designs, meaning most comparable cruisers carry less ballast relative to their weight. The length-to-beam ratio is 3.17, and her beam of 11.42 feet makes her roomier than 54 percent of all other designs measured that way.
What truly defines the Tiburon 36 is her displacement-length ratio of 374, which places her among the "ultra heavy cruisers". Only 14 percent of similar designs are heavier. That mass is not wasted: her Motion Comfort Ratio of 40.1 means she is more comfortable than 96 percent of all similar sailboat designs when the sea gets messy. The capsize screening value of 1.66 is low enough that, by that formula alone, she could be accepted to participate in ocean races — a reassuring metric for a boat built to carry people safely across basins rather than win buoy mornings.
Rig and Handling
The Tiburon 36 is built with a ketch rig, a configuration that splits the sail plan into manageable chunks for a small crew and balances her for downwind work. Her sail-area-to-displacement ratio is 20.18, firmly in the modest range that confirms she is built to be carried by her ballast and hull form rather than driven hard by canvas. The theoretical hull speed is 7.2 knots, the natural limit of a displacement hull of her length.
The standing and running rigging dimensions quoted for the boat are generous: the mainsheet runs 90.5 feet and the jib and genoa sheets each run 36.2 feet, all in 14 mm diameter. The spinnaker sheet is quoted at 79.6 feet, also 14 mm. These are estimates for sheet length and diameter, but they indicate a rig sized for control rather than minimalism. The wetted surface of the bottom is about 355 square feet, a large area that contributes to her tracking and comfort but also to the effort needed to drive her through the water.
Accommodations
The Tiburon 36's interior volume benefits from her 3.17 length-to-beam ratio, which makes her roomier than just over half of comparable designs. The ketch rig's mizzen mast intrudes into the cabin, but it also shortens the mainmast and opens the saloon. At 21,000 pounds displacement with a 29.25-foot waterline, the boat was clearly laid out to live aboard for extended stretches rather than to maximize racing crew mobility. The immersion rate of 1,164 pounds per inch means she settles slowly under stores and water — a virtue for a cruiser loading for passage.
Known Issues
The Tiburon 36 carries no known structural defects or systemic faults in its service history. The estimated iron ballast and attached rudder are unconfirmed attributes, so they cannot be cited as defects or virtues. The boat is heavy, slow to accelerate, and dependent on a long-keel form that limits her upwind agility in tight channels. These are design characteristics, not faults.
Refits and Ownership
Ownership of a Tiburon 36 means coming to terms with her as an ultra-heavy cruiser: the 20-horsepower Chrysler diesel moves 21,000 pounds at a modest pace, and the 960 square feet of sail area demands disciplined trimming on a ketch. Refits tend to center on rigging upgrades and the slow replacement of period systems. The 7,000-pound iron ballast (an estimated figure) and solid hull mean there is little to rot or delaminate in the primary structure, which keeps long-term ownership focused on machinery and canvas rather than structural reconstruction.
The Verdict
The Tiburon 36 is a Crealock-designed ketch for sailors who value comfort and seaworthiness over velocity. Her numbers place her among the heaviest and most stable cruisers of her size, and her long keel and solid build make her a dependable passage-maker.
Pros
- More comfortable than 96% of similar designs by Motion Comfort Ratio
- Ultra-heavy cruiser classification with only 14% of peers heavier
- Capsize screening low enough for ocean-race acceptance by formula
- Solid fiberglass hull and deck, no core to fail
Cons
- Sail-area-to-displacement of 20.18 and 7.2-knot hull speed limit performance
- Long keel and 5.3-foot draft restrict shallow exploration
- Beam ratio leaves her roomier than only 54% of comparable boats
