Excess 11

The Excess 11 is a cruising sailing catamaran with twin aft helm stations, offered with three or four cabins. Naval architecture is by VPLP, exterior design by Patrick le Quément and interiors by Nauta Design.

The manufacturer currently presents Standard, Riders’ Edition and Hybrid versions. The specifications below describe the standard diesel boat unless a different version or option is named. Equipment, finishes and layouts vary by configuration; model photographs do not represent the inventory of any individual boat for sale.

The open cockpit connects the two steering positions with the crew’s living space. The owner’s cabin can accommodate a 2 × 2 m bed, and the bathrooms have separate showers. Interior finishes include Cedar & White Touch, with three decoration schemes described by the manufacturer.

Pulse Line increases the upwind sail area from 90 to 95.5 m²; the 54 m² Code 0 is optional. Riders’ Edition adds dedicated storage and outdoor equipment for carrying activity gear. The Hybrid version combines two electric pod motors with a generator; these are alternatives to the standard diesel installation, not additional standard equipment.

The manufacturer displays the 2021 SAIL Best Boats winner badge and Cruising World’s 2021 overall Boat of the Year award.
