The Crowther Buccaneer 33 represents a pivotal moment in multihull evolution, designed by the legendary Australian naval architect Lock Crowther during the late 1960s. As part of a lineage that helped transition trimarans from experimental curiosities to respected offshore cruisers, the Buccaneer 33 was specifically engineered to balance high-speed performance with the structural integrity required for blue-water passages. Unlike many of its contemporaries that relied on heavy displacement, the Buccaneer 33 utilized a lightweight, high-buoyancy philosophy, often constructed using marine plywood and epoxy (and later, composite materials) to maintain a favorable power-to-weight ratio. It remains a cult favorite among multihull purists who value a "sea-kindly" motion and the ability to outrun weather systems.

Sailing Performance & Handling

The Buccaneer 33 is celebrated for a "lively" feel that many modern, high-volume cruising catamarans lack. Its design features a deep V-shaped main hull and asymmetrical or semi-asymmetrical amas (outriggers), which provide significant lift and reduce drag when the boat is pressed. According to historical design notes from Crowther Multihulls, the boat was intended to achieve speeds in excess of 15 knots under favorable conditions, a feat it accomplishes through a high sail area-to-displacement ratio.

Handling is characterized by remarkable tracking, largely due to its efficient daggerboard system which allows for superior upwind performance compared to fixed-keel multihulls of the same era. Owners often report that the boat "finds its groove" quickly, though the low freeboard of the amas can result in a "wet" ride in choppy seas. The buoyancy distribution is focused forward to prevent pitch-poling, a common fear in early multihull design, making the Buccaneer 33 a relatively safe platform for experienced offshore sailors.

Interior Comfort & Variations

While the Buccaneer 33 is a capable cruiser, its interior reflects the narrow beam of its central hull. Unlike modern wide-body catamarans, the living space is confined to the main hull, offering a layout that is functional but compact. The "B33" typically features a modest galley, a small settee that can double as a berth, and a V-berth forward. Headroom is generally adequate in the center of the cabin but tapers quickly.

The model saw several variations during its production life. While the core design remained a 33-foot trimaran, builders often modified the deck mold. The "Buccaneer 33" hull served as the middle ground between the smaller, more spartan Buccaneer 24 and the much larger, more luxurious Buccaneer 40. Some versions were built with "wing" extensions to increase deck space, while others remained strictly utilitarian. Because most were built from plans, the quality of the interior finish varies wildly between boats, ranging from raw industrial aesthetics to fine-timber cabinetry.

Known Issues & Buyer’s Checklist

Prospective buyers must approach the Buccaneer 33 with a focus on structural longevity, particularly because many were home-built from plywood and resin.

  • Crossbeam (Aka) Integrity: The most critical inspection point is the connection between the main hull and the amas. Any signs of delamination, soft spots, or "working" (movement) in the crossbeams or their mounting points are immediate red flags.
  • Plywood Rot: For wood-core examples, moisture ingress in the amas or the transom can lead to catastrophic rot. A thorough percussion test or moisture meter reading is essential along the waterline and near through-hull fittings.
  • Daggerboard Trunk: The trunk is a high-stress area. Inspect for cracks or evidence of previous grounding damage, which can lead to leaks that are difficult to access and repair.
  • Rigging Loads: Because trimarans do not heel like monohulls, the standing rigging absorbs much higher loads. Buyers should verify the age of the shrouds and the condition of the chainplates, which are often buried in the hull structure.

Community & Resources

The legacy of Lock Crowther is preserved by a dedicated global community. While the original design firm has evolved, technical support is often found through the Crowther Multihull owners' groups and archives. Historical data and design philosophies are frequently discussed within the Multihull Yacht Club of Australia (MYCA), which maintains records of Crowther’s significant contributions to the sport.

The Verdict

The Crowther Buccaneer 33 is a "sailor’s multihull," offering a level of feedback and speed that modern "condo-marans" cannot match. It is an ideal vessel for the enthusiast who prioritizes performance and heritage over sprawling interior volume.

Pros:

  • Exceptional speed and agility for a 33-foot cruiser.
  • Proven offshore pedigree with several recorded ocean crossings.
  • Strong upwind capability thanks to the daggerboard design.
  • Aesthetic "classic" multihull lines that stand out in any harbor.

Cons:

  • Interior living space is narrow and limited compared to modern catamarans.
  • High maintenance requirements, especially for older plywood/epoxy hulls.
  • "Wet" ride in heavy weather due to low-slung amas.
  • Significant variance in build quality due to the nature of plan-built boats.
