1988 Joubert Custom Trimaran

This 78-foot trimaran was designed and built by Joubert as a full-beam multihull capable of carrying up to 12 guests across 6 double cabins, with accommodation for 3 crew members. The boat features seven heads and a layout optimized for short-handed operation, with a dedicated maneuver cockpit separate from the main helm station.

Power comes from three diesel engines: a Perkins 60 hp unit in each outrigger hull and a Volvo 350 hp engine in the central hull, all direct-drive. Fuel capacity totals 5,000 liters across three tanks. The yacht is equipped with two Westerbeke generators producing 18 kW and 8.5 kW respectively, supporting dual air conditioning and refrigeration systems specified to professional standards with full redundancy.

The aluminum mast carries three furling headsails on separate headstays, with double shrouds on each side. The three full keels are designed to allow beaching. The trimaran hull form and 78-foot waterline length provide motion characteristics suited to open-water cruising, particularly in heavy seas. Fiberglass construction throughout.

The yacht was operated by a single ownership since its build and has seen extended use cruising the Red Sea, Indian Ocean, and Mediterranean under professional management. Systems throughout are specified for autonomous operation in remote waters, with robust and redundant configurations across power, propulsion, and hotel services.
