Sailfish sailboat is a small, hollow body, board-boat style sailing dinghy. The design is a shallow draft, sit-upon hull carrying a lateen sail mounted to an un-stayed mast. This style sailboat is sometimes referred to as a “wet boat” because, with its minimal freeboard, the sailor often gets splashed by spray as the boat moves across the water.

The distinctive low-aspect ratio lateen sail gives the Sailfish a unique squat appearance compared with today's more familiar high-aspect ratio Bermuda rig sailboats. First impression of this low profile rig might be that it sails awkwardly, however, the lateen sail plan shifts the advantage toward better performance in light air and also contributes to it having good down-wind characteristics. The lateen sail along with its simple two line rigging made the Sailfish one of the easiest boats ever to learn fundamentals of sailing on.

Sailfish as the trade name for a board-boat first appeared in 1945. The brand-name Sailfish sailboat was designed and built by Alcort, Inc., Waterbury, Connecticut, a company founded by Alex Bryan and Cortlandt Heyniger. This boat building duo started out constructing iceboats and branched into small sailboats after being presented with a request to quote on a paddle board for the Red Cross. The project didn't pan out with the Red Cross, but Alex and Cortlandt felt an improved version might make a viable personal sailboat.[1]

In 1949 LIFE Magazine published an article showcasing the Sailfish as, "the sportiest little sailing craft afloat".[2] The write-up praised Alcort, Inc. and its Sailfish sailboat for adding a new and economical dimension to waterfront recreation. As a result of the national notoriety, Sailfish, and Alcort's later design, the Sunfish, became so well known their brand names invaded the lexicon synonymous for nearly any board-style boat sporting the characteristic lateen sail.

Early Sailfish were offered in the form of boat plans for the backyard boat builder along with an option to purchase the boat from the Alcort shop fully assembled and ready to sail.

In the beginning do-it-yourself boat builders crafted every piece, formed and assembled all the hardware from raw metal stock, and even sewed their own sail. Boats built in the Alcort shop received a sail obtained through Old Town Canoe Co., made by sailmaker, Ratsey-Lapthorn. Eventually, Alcort had Ratsey-Lapthorn make a sail specifically for the Sailfish, eliminating the middleman and establishing Ratsey-Lapthorn as Alcort's regular sail provider, a status they retained until 1979.[4]

Not long after introducing the Sailfish, Alcort had the brilliant notion to reach an even broader market by supplying the boat in kit form. The kit contained a complete, ready-to-assemble boat in pre-cut pieces with all the hardware and sail included. This provided a way for those who were handy at projects in general, but who lacked the specialty tools and specialized skills for working with raw materials to still be their own boat builder. From that point forward, the Sailfish came as a kit for the do-it-yourselfer or ready-to-sail, fully assembled by Alcort. Sailfish were available in two models, the 11’ 7½” Standard Sailfish and the 13’ 7” Super Sailfish.

Alcort took the hollow body board-boat concept to the next level in 1959 when it introduced the Super Sailfish with a fiberglass hull. They named this model the Super Sailfish MK-II. This was the most popular model and the one a majority of sailors remember as simply the "Sailfish".

The Sailfish began as the 11’ 7½” (3.5 m) Standard model. Shortly after its inception a larger, 13’ 7” (4.2 m) Super Sailfish model was made available. In the early years the mast and spars were made from Sitka spruce and the sail was cotton. Historic photos show sails with as many as 10 panels and even small battens inserted. Sails in those days were lashed to the spars with line in the traditional manner instead of being attached by the plastic sail clips that became another familiar characteristic of this boat in later years. One of Alcort's first innovations for the Sailfish was to create a kick-up mechanism that automatically swung the rudder into a horizontal position for easy beaching. By the late 1950s the option of either a nylon or Dacron polyester sail in solid colors of red or blue became available to complement the previous white only sail.

In 1959 the fiberglass 13’ 8” (4.2 m) hull Super Sailfish MK-II model was added to the lineup. The MK-II sported an aluminum mast and spars. The deck was available in colors of red, white, blue, green, and yellow with a five panel Dacron sail in alternating panel colors to match the boat’s deck color.

Not long after the fiberglass MK-II came onboard Alcort stopped supplying the factory assembled wood models. However, according to the sales brochures[5], the wood boats continued to be available in kit form long into the 1960s.

Alcort, Inc. sold their boat building company to AMF in 1969. AMF named their boat division for the founding Alcort Co., capitalizing on the tremendous name recognition Alcort, Inc. had built up over its 24 year history.

Little was done with the Sailfish design in the ensuing six years except to upgrade the rudder blade’s shape in 1972 to the more streamlined design also used on the Sunfish. At the time of upgrade the bronze rudder hardware of the now waning Sailfish remained the same while the Sunfish was fit with a new design.

AMF discontinued the Sailfish in 1975.

The Sailfish successor, Sunfish, continues to be built and is now found world wide.[6]

The additional inch is a result of the flange where the deck and hull bottom are bonded together as one.
