If your focus is safe, comfortable fast cruising here is an answer. Trimarans provide stability and speed which equal safety. More stable than a catamaran, with the speed of a multihull mena less rig loads, fast passage making and much larger deck space when you arrive at a new anchorage. FINN has first class pedigree, designed by Banuls (Oracle AC trimaran), built by McConaghy for a client with years of multihull experience. The result is the exceptional n53 trimaran, delivering fast, stable and safe cruising capacity.

Aft for both performance and seawater supply for on board watermaker


The concepts that brought forth FINN are; safety, simplicity and comfort. As with all great yacht design the greatest challenge is to find the balance of safety, comfort, performance and still please the eye and the heart. The interior delivers the design objectives with remarkable space and comfort.
Aft is the main cabin, amidships is the saloon and the one large head, forward is the second cabin.
Large deck hatches, generous port lights and LED lighting deliver natural and shadowless lighting. Generous berths, ample storage, a large head with shower, carbon vanity and yes a carbon toilet provide the comfort a cruising boat must deliver.
The Whisper Wall system on the overhead and hull ceiling provide a "cocoon of silence" with a fraction of the weight for typical overhead panels and linings.
The Galley has Wallas cooktop and oven, Isotherm refrigeration, carbon countertops, integral stainless steel "hot racks".
All of this is a warm inviting finish of Sepele veneers, Amtico flooring, warm white paint and bright carbon details.
