Sailpages Buyer's Take

Designed by Nigel Irens and built by Gunboat starting in 2015, the Gunboat 55 is a high-performance offshore racer-cruiser known for its aggressive styling and twin-engine layout. While the exact hull count is unspecified, the model represents a significant entry in the modern performance cruising market, combining speed with substantial offshore amenities.

Best for:
This boat is ideal for experienced offshore cruisers and racers who prioritize speed and performance, as evidenced by the high prevalence of performance sailmakers like North Sails and advanced electronics such as Nexus and B&G. It suits owners willing to invest in significant maintenance and upgrades, given the high frequency of reported issues and the commonality of major installations like solar panels and watermakers.
Bluewater capability:
With a displacement of 27558.0 lb and a capsize ratio of 3.31, the Gunboat 55 is structurally designed for serious offshore passage-making, though its performance-oriented hull form and high SA/D ratio of 36.2 require skilled handling in heavy weather.
Comparables:
Comparable boats include the X-Yachts X-43 and the Swan 44, which share similar performance-oriented hull forms and target the same high-end offshore market. The Gunboat 55 distinguishes itself with its twin-engine configuration and wider beam, appealing to those seeking greater interior volume and redundancy compared to single-engine competitors.
