Monohull Sailboat

Monohull boats rely on ballast in the keel for stability, and are commonly known as displacement hulls.

Depending on the design, ballast will be 20 to 50 percent of the displacement, incorporated into the keel as large masses of lead or cast iron. The weight, depth and length of the keel determine the stability and performance of the sailboat.

Displacement: Boats with displacement hulls have much greater stability and take less fuel to operate, but their speed is limited to the length of the hull (1.34 times the square root of the length of the hull, in feet, at the water line.

The most common type of small to midsize sailboat is the sloop. The rig is one mast and two sails. The mainsail is a tall, triangular sail mounted to the mast at its leading edge, with the foot of the sail along the boom, which extends aft from the mast. The sail in front, called the jib or sometimes the head sail, mounts on the forestay between the bow and the masthead, with its trailing corner controlled by the jibsheet.

Engine:

The original Sabre 28 was built with the Universal Atomic 4 gasoline engine and, in 1975, a 10 hp Volvo diesel was offered as an option to the Atomic 4. From 1978 through 1980 the standard engine was the 13 hp MD7A Volvo marine diesel. This was replaced with the 13 hp Westerbeke diesel in 1981. The propeller and shaft were set at an angle off the centerline to either the port or starboard side of the vessel depending weather a right hand or left hand rotation engine was used. If one ever intends to re-power it is important to keep in mind that the rotation of the engine must be the same as the original or you will encounter considerable handling difficulties under power.

Introduced at the 1971 Newport Boat Show in an unfinished state, the 28 got people’s attention. Teak toerails on deck and a rich, wood-finished interior added luster to a boat that had a surprising minimum standing headroom of 5’11” and could feed and sleep a full family crew. The good-sized masthead rig was deck-stepped, which further enhanced the interior, and in combination with moderate displacement, gave the 28 a 20.6 sail area/displacement ratio. That was robust for its era, given the boat fit under IOR Half Ton rating and was often raced. Today, the 28 still competes on PHRF race courses across the country with a rating usually below 200.

The 28 was built with polyester resin and hand laid glass on a laminate hull. The decks were light, made with balsa coring except in high-load areas where plywood was substituted. Sabre’s quality workmanship was evident immediately to buyers,"The boat has proven to be a good investment due to its ability to attract buyers willing to pay a little more than average for a better-than-average quality product."

Sabre Yachts of South Casco, Maine, introduced the Sabre 28 in 1972 and was the only model built by Sabre built until 1977. The 28 continued production until 1986. Over the 14 years of production, three versions of the boat were offered with only slight variations from the original design. In 1975 the deck was changed to incorporate a well in the foredeck for anchor and rode storage and the cockpit was changed to accommodate the popular wheel steering without interfering with the opening of seating arrangements. In 1984 the keel was redesigned and the height of the rig was increased slightly.

The American Sailboat Hall of Fame was established in 1994 by Sailing America. The basic criteria for Hall of Fame consideration requires that candidates be production sailboats, built in the United States, introduced at least 15 years ago. The defining characteristic that each boat shares is that each has made a difference - a lasting impact on sailing. Sabre 28

Sailing Wind Wheel's Description
The Sailing Wind Wheel is constructed with a boat on a clear disc that allows the boat to rotate 360° (see the Sailing Wind Wheel in “Action”)

The sails rotate independently to create an understanding as to how the sails need to be adjusted and move on various Points-of-Sail. It makes visualizing maneuvers like Tacking & Jibing, Heading up and Heading down very clear.

The wind fellows show the wind direction and red arrow shows through the boat, simulating the windvane at the top the mast. It is a constant reminder of where the wind is coming from in relationship to the boat.

The two red tabs from the windex are shown on the boat so students know how to keep out of the No Sail Zone. The No Sail Zone is clearly indicated on front and back.

The Points-of-Sail are show in degree of angle as well as relationship to a clock.

Port and Starboard Tacks are made clear with the red and green on the sides of the boat.

On the back the Points-of-Sail are broken down like slices of pie to give a simplified way to understand the relationship of the boat to the wind.
