THE COMPANY

Horizon Yacht Company of Largo, Florida, manufactured the Horizon 39 during the 1980's. Barry Scharf owned the company. Barry commissioned yacht designer Burk Borges, who did many Morgan designs, to design the Horizon 39. The company built 30 – 40 boats during the 1980’s, and enjoyed the reputation as a quality cruising boat builder.
Most were sold as kits for “one of a kind” custom rig and interior fitting, but
several boats were completely finished and sold under the name NEMO 39.
The price in 1984 for a finished NEMO 39 boat was $140,000.

Bare hulls with a deck started at around $30,000 with two transom styles: traditional for
ketch and reverse for cutter/sloop plan. The company was expanding to include a 45’ modelin addition to the 39 and 26 when the market for cruising boats collapsed.

The company went out of business in 1988.

HULL AND DECK CONSTRUCTION

Construction of hull was very high quality, using .06” Isothalic gel coats and laminating resin.
The 4 layers of 1.5 oz. mat and 24 oz. Woven roving were laid down longitudinally,
over the full length of the hull, with 12” overlaps at the waterline, garboard area, and keel.
One additional layer was laid down from above the WL to mid-keel and 2 additional layers from
mid keel to the centerline. When the hull was complete, a 4” inward turning hull flange was
laminated to the upper 12” of the hull, doubling the thickness at the sheer. The production
rate was slow, allowing each hull about 3 weeks in the mold. The hull mold was a one piece
lamination, heavily reinforced, and set on rollers.

The deck mold was adapted from Morgan 40 tooling. The deck lamination schedule included .06” ISO gel coat and 1.5 oz. Mat, 2 layers of mat and 24 oz. Woven roving, a 0.5” plywood
core bedded with wet chop over all deck surfaces, including the cabin sides and 1 additional
layer of 1.5 oz. Mat and 24 oz. woven roving.
Most Horizon boats were finished with traditional interiors.
