Solid Fiberglass Hull | Nida Core Construction | Licensed for Short International Crossings | 110-Passenger Capacity

Presenting the Sting Ray II, a rare opportunity to own a professionally designed, custom-built 55-foot fiberglass power catamaran optimized for commercial operation. Designed with safety, durability, and versatility in mind, this twin-hull vessel is a top performer in coastal and near-offshore service roles, from whale watching and scuba diving excursions to inter-island passenger ferry routes and private charters.

Built in 1988 and meticulously maintained throughout her service life, Sting Ray II was constructed using a solid fiberglass hull and Nida Core composite materials throughout the superstructure, with no wood used anywhere onboard, eliminating concerns about rot, water absorption, or long-term structural degradation.

At 55 feet in length, her wide beam and stable platform make her ideally suited for large-group tours, marine exploration, and short international crossings, such as those frequently made between Caribbean islands or similar regional transport routes.

Proven Hull Design
Inspired by Racing, Built for Comfort.
The Sting Ray II stands apart from typical commercial catamarans thanks to its Cigarette-style hull mold origin a design DNA inherited from one of the most successful offshore powerboat builders in the world. This unique hull form gives Sting Ray II a number of distinct advantages:

Efficient hydrodynamics, minimizing drag while maintaining a smooth, wave-cutting ride

Improved stability at speed and at rest, thanks to the wide catamaran beam

Reduced fuel consumption compared to similarly sized monohulls

Smooth handling in both coastal chop and longer offshore swells

Wide deck footprint with ample space for passengers, equipment, or service areas

The result is a vessel that is not only faster and more stable but also more comfortable for passengers, especially important for day cruises, diving tours, or long inter-island routes.

Construction is of Composite Quality, Built to Last
Unlike many commercial boats of her age, Sting Ray II features a solid fiberglass hull paired with Nida Core composite material throughout the rest of the structure. This gives her a critical advantage in terms of long-term maintenance, operating cost, and safety.

Construction Details:

• Zero wood, no rot, no swelling, no hidden water damage
• Nida Core structural panels, lightweight yet incredibly strong
• Decks and superstructure reinforced for heavy traffic and load-bearing
• Non-skid flooring and secure handrails for passenger safety
• High freeboard and self-bailing decks for dry, secure operation
• Solid laminated hull for impact resistance and strength in rougher waters

This modern material combination ensures decades of continued use with minimal structural degradation and significantly reduces long-term operating costs.
