Design and Construction
The Tiburon 36 measures 36.2 feet overall, with a 29.25-foot waterline and an 11.42-foot beam. Its length-to-beam ratio is 3.17, making it roomier than 54 percent of other designs measured that way.
Both the hull and deck are solid fiberglass, laid up without cores. Depending on load, draft ranges from 4.99 to 5.29 feet. That keeps the boat out of the shallowest anchorages, though it can enter most marinas without drama.
A long keel provides the directional stability and grounding tolerance expected of a bluewater cruiser rather than a fin-keel weekend boat. The boat displaces 21,000 pounds and carries 7,000 pounds of iron ballast, though the ballast material is an estimated attribute. Its ballast ratio is 33 percent—a figure higher than only 15 percent of similar sailboat designs, meaning that most comparable cruisers carry less ballast relative to their weight.
The defining number is a displacement-to-length ratio of 374, which puts the Tiburon 36 among the “ultra heavy cruisers.” Only 14 percent of similar designs are heavier. That mass also contributes to a Motion Comfort Ratio of 40.1, making the boat more comfortable than 96 percent of similar sailboat designs when the sea gets messy.
Its capsize screening value is 1.66. By that formula alone, the boat could be accepted for ocean racing—a reassuring metric for a design intended to carry people safely across basins rather than win buoy mornings.
The bottom has about 355 square feet of wetted surface. That large area contributes to tracking and comfort, but it also increases the effort required to drive the boat through the water. The attached rudder is an unconfirmed attribute and therefore can’t be treated as either a virtue or a defect.
Rig and Handling
The Tiburon 36 has a ketch rig, which divides the sail plan into manageable sections for a small crew and helps balance the boat for downwind sailing. The mizzen mast intrudes into the cabin, but the arrangement also permits a shorter mainmast and opens the saloon.
The quoted sail area is 960 square feet, while the sail-area-to-displacement ratio is 20.18. That modest ratio confirms that the Tiburon is built to be carried by its ballast and hull form rather than driven hard by canvas. Its theoretical hull speed is 7.2 knots, the natural limit for a displacement hull of this waterline length.
Quoted standing and running rigging dimensions are generous. The mainsheet is 90.5 feet long, while the jib and genoa sheets are each 36.2 feet, all in 14 mm diameter. The spinnaker sheet is quoted at 79.6 feet, also in 14 mm diameter. These sheet lengths and diameters are estimates, but they suggest a rig sized for control rather than minimalism.
The Tiburon’s weight makes it slow to accelerate, while the long keel limits upwind agility in tight channels. These are characteristics of the design rather than faults.
Accommodations and Load Carrying
The boat’s 3.17 length-to-beam ratio gives the interior useful volume, making it roomier than just over half of comparable designs. With a displacement of 21,000 pounds on a 29.25-foot waterline, it was clearly laid out for extended living aboard rather than maximum mobility for a racing crew.
An immersion rate of 1,164 pounds per inch means the boat settles slowly as stores and water come aboard. That’s a virtue for a cruiser being loaded for a passage.
Known Issues
The Tiburon 36 has no known structural defects or systemic faults in its service history. The estimated iron ballast and unconfirmed attached rudder shouldn’t be cited as either defects or virtues.
Its heavy displacement, slow acceleration, long-keel handling, and relatively deep draft are inherent design characteristics. They come with practical limitations, particularly in tight channels and shallow cruising grounds, but they aren’t faults.
Refits and Ownership
Owning a Tiburon 36 means accepting it on its own terms as an ultra-heavy cruiser. Its 20-horsepower Chrysler diesel moves 21,000 pounds at a modest pace, and the 960-square-foot sail plan requires disciplined trimming across the ketch rig.
Refits tend to focus on rigging upgrades and the gradual replacement of period systems. With a solid hull and an estimated 7,000 pounds of iron ballast, there is little to rot or delaminate in the primary structure. Long-term ownership therefore tends to center on machinery and canvas rather than structural reconstruction.
Verdict
The Tiburon 36 is a Crealock-designed ketch for sailors who value comfort and seaworthiness over speed. Its numbers place it among the heaviest and most stable cruisers of its size, while the long keel and solid construction support its role as a dependable passage-maker.
Pros
- More comfortable than 96 percent of similar designs by Motion Comfort Ratio
- Ultra-heavy cruiser classification, with only 14 percent of peers heavier
- Capsize screening value low enough for ocean-race acceptance by formula
- Solid fiberglass hull and deck, with no cores to fail
Cons
- Sail-area-to-displacement ratio of 20.18 and a 7.2-knot hull speed limit performance
- Long keel and draft of up to 5.29 feet restrict shallow-water exploration
- Length-to-beam ratio makes it roomier than only 54 percent of comparable boats
