Difference Yacht for Sale | 54 Alibi Yachts St Augustine, FL

Difference Boat | 54' Alibi 2011

Exceptional deal on an amazing performance catamaran! US Import Duty Paid. This is a preliminary listing - new photos and video coming soon!

DIFFERENCE is a stunning example of the renowned Alibi 54, for those unfamiliar with the brand, it is a semi-custom, high performance cruising catamaran built and designed by a French catamaran designer in Thailand. She's a cutting-edge catamaran for the sailor seeking a yacht with the beauty and performance of a fine sports car but which still has the room and appointments for a family cruise. At just under 12 tons dead weight, with dual, asymmetric push-button operated daggerboards, all carbon fiber rotating mast and all of the creature comforts, she can easily exceed wind speed. Yet her handling is sure, predictable and smooth in all weather. She was designed and built by a racer, but aimed mainly at a performance cruising minded clientele. An exceptional balance of performance, safety, luxury and modern aesthetics.

Currently on her second owner, both owners of Difference have maintained her meticulously and have invested heavily in upgrading and perfecting her. She has never been chartered, only sailed privately throughout the Caribbean, Bahamas, and the US East Coast. In 2022, two brand new Volvo 50hp engines and saildrives were installed, and her entire electrical system was upgraded and modernized with a Lithium house battery bank. She has also been modified from her original design to install larger, under-hung rudders to replace her original smaller lifting cassette designed rudders. From 2024 to 2026, she underwent an extensive refit at Grenada Marine including a complete deck and topside repaint, full mast service and electrical rewire, and comprehensive mechanical and cosmetic restoration.

The right buyer for Difference is a sailor who appreciates the advantages of a true performance multihull and refuses to tolerate the slow speeds and poor windward sailing characteristics offered by most production catamarans. She’s a sailor’s catamaran, pure and simple. So, if you like speed, if you want a stunningly beautiful looking, high-end epoxy catamaran, Difference may be for you. New North 3DI sails, Kevlar rigging, carbon rotating mast, carbon spars, new BG, Furuno and Maretron electronics, etc. She’s easily the best value high performance catamaran on the brokerage market in the world today.

North 3Di Endurance Sails including Main, Jib, Gennaker, Code 0, and two spinnakers
