The Eenhoorn (Unicorn) was built in 1903 in Zeeland and was used as a general cargo carrier. She was upgraded and completely rebuilt/remodeled in 1990 as a cruising vessel.

The overall length of the Eenhoorn is 96 feet, and the beam is 21 feet, with a draught of only 5 feet. Boats built for these waters have no keel and are flat bottomed. 13,000 lbs of fresh water and 46,000 lbs of cement provide sailing stability.

Lateral sailing stability is provided by two large leeboards. The main and mizzen sails were gaffs rigged.

Hoisting the approximately 500-pound main gaff was accomplished with a hand cranked geared winch.

With 5 sails totaling approximately 4,100 square feet of sails.

The Captain's quarters are topside aft. Below deck aft are the crew accommodations.

Topside just forward of the mizzenmast, is a large cockpit that will comfortably seat a dozen people. A large starboard companionway leads below into the large saloon and gallery. Forward of the saloon are ten cabins, two bunks per cabin.

Each cabin has a small wash basin, opening skylight, and a door into a shared bath/shower.
