Detecting an untapped performance-oriented yet “green” niche within the sailing market, Sunreef Yachts has added another series of catamarans to its varied lineup. Called Ultimate, the series will include 80- to 150-footers, with the 80 Ultimate shown here being the first model available.
Ultimate is based on Sunreef’s own ideas as well as opinions solicited from potential clients. There are a few examples of each being incorporated on the 80 Ultimate, measuring 25 meters, or 82 feet LOA. To save weight and therefore enhance performance, Sunreef’s in-house naval architects decided to employ a lower-profile superstructure and carbon fiber construction for the hulls. Reverse bows and stepped hulls will also enhance performance. (A stepped hull features an indentation running from the outer chine all the way to the keel, thereby creating separate forward and aft surfaces. The place where the two intersect looks much like a stair, or step, hence the name.) To address buyers’ desire for bright, light interiors and, of course, great views, the 80 Ultimate will feature large skylights and glass swaths across the entire forward part of the superstructure. For clients who like more entertaining space, a flying bridge is an option.
As for the eco-friendly features, vertical wind generators are being included on each hull, retractable when not needed. Optional solar panels, again to be fitted on each hull, can power the water-heating system. Sunreef is additionally researching hybrid propulsion methods. Preliminary research into traditional diesel power shows that twin 240-hp engines will permit the 80 Ultimate to hit a 12-knot cruise. Under sail, she should see 20 knots or better at top speed.

In keeping with its other catamarans plus other builders’ offerings, Sunreef is outfitting the 80 Ultimate with two helms in the cockpit and one inside. Wide staircases rise up the aft portion of each hull, for easy entry into/exit from the water. Up to 12 guests can stay aboard the superyacht, too – far more than a monohull 80-footer. As for the interior layout, Sunreef will allow some customization within two plans. The first features an open saloon, containing both lounging and dining areas; the second provides separate spaces for the saloon, dining area, and galley. Either way, the master is fully forward on the main deck, with sliding doors to a private terrace and spa tub, bar, and seating/lounging area. Guests and crewmembers are being accommodated in the lower portion of each hull.
The first 80 Ultimate is available for sale.
