Gunboat 55 “VANDAL” – Ultimate Owner-Operated Performance Cruiser
VANDAL is a high-tech, lightweight Gunboat 55 catamaran built in the USA and designed for fast, shorthanded world cruising with outstanding performance, safety, and luxury. Constructed entirely in carbon fiber, this 57-ft LOA yacht combines strength and speed with a sleek, modern profile. Capable of sailing comfortably at 14 to 21 knots and achieving 250+ mile days, VANDAL is the perfect platform for couples or small crews seeking serious offshore capability.
With a smart galley-up layout and an open, bulkhead-free main salon, the living space flows seamlessly into the cockpit, offering a bright, social atmosphere ideal for entertaining or relaxing at anchor. Below, you'll find three queen+ staterooms with bold, stylish finishes and two well-appointed heads. VANDAL has been significantly upgraded post-construction, including reinforced rigging, improved steering systems, and a solar power array — all completed at Newport Shipyard in collaboration with Gunboat, incorporating two decades of real-world performance insight.
This Gunboat is fully equipped for long-term cruising with lithium batteries, solar panels, air conditioning, a generator, watermaker, electric winches, and a full suite of B&G electronics including AIS and radar. She features performance keels for safe, fast upwind sailing without the complexity of centerboards. Recent maintenance includes new bottom paint and PropSpeed in Nov 2024, and an out-of-water bottom survey with thermographic imaging, showing no issues.
Whether you're coastal cruising, crossing oceans, or hosting sunset gatherings, VANDAL delivers everything you expect from a Gunboat — speed, style, innovation, and confidence.
