bullseye sailboat trailer

Bull’s Eye

Designed by: captain nathanael herreshoff.

Based on the Herreshoff H-12½ design, the Bull’s Eyes deck has been modified to handle stronger winds and seas yet the hull shape remained unchanged. She carries all of the same sailing characteristics as the Herreshoff H-12½ providing the seaworthiness that has made the design so famous. The Bull’s Eye has a nice size cockpit that will comfortably accommodate 4 or 5 adults however, can be easily single handed with her self tending jib. With the optional trailer the Bull’s Eye can be launched and rigged at a ramp. The Bull’s Eye has active one-design racing fleets from Florida to Maine and an active national association.

Bullseye is a 15 ′ 8 ″ / 4.8 m monohull sailboat designed by Nathaniel G. Herreshoff and A. Sidney DeWolf Herreshoff and built by Quincy Adams Yacht Yard, Herreshoff Mfg. Co., and Cape Cod Shipbuilding starting in 1914.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Originally designed and built by Nat Herreshoff of wood in 1914 and called the HERRESHOFF BULL’S EYE. In 1938 she was modified with an above transom tiller, and named The FISHERS ISLAND SOUND BULL’S EYE. In 1947 the rights to the design were purchased by Cape Cod Shipbuilding Co. In 1949 a fiberglass version of the FISHERS ISLAND SOUND BULL’S EYE was introduced (overseen by Sidney Herreshoff) that also featured a cuddy cabin and modern marconi rig on an aluminum spar. This became the THE CAPE COD BULL’S EYE. (pictured here) Throughout the evolution of different decks and rigs, the hull design has remained unchanged from the original first built at Herreshoff Mfg. Co.

Cape Cod Shipbuilding Co.

Master builders of fine sailboats since 1899 7 narrows road, p.o. box 152, wareham, ma 02571 telephone: (508) 295-3550 fax: (508) 295-3551 [email protected].

The Cape Cod Shipbuilding Co. was founded at the turn of the century by Captain Charles S. Gurney, and during his lifetime over 16,000 boats were built ranging up to 100 ft., but mostly in the 12 to 20 ft. size. Best known at that time was the Cape Cod Baby Knockabout, which with other models was shipped to all parts of the World.

E.L. Goodwin purchased the company in 1939. His policy was - and is - to build quality boats and to maintain service on parts for those boats previously built.

During the World War II, Cape Cod went into production of wood boats for the armed services. Fortunately the business procured was for boats under 51 ft., the type which the plant and personnel was best equipped to handle. On one contract the plant produced 46 ft. tug boats for the U.S. Army Transportation Corps at the rate of one and one-half per week.

In 1941 the small boat department of George Lawley & Sons, Inc. was purchased and immediately moved to Wareham. Along with the jigs, forms and patterns received from Lawley’s came much of the "knowhow" gathered over the years in the manufacture of fine boats. At the end of the war, the benefits of continuing small wood boat construction was reaped since production on pleasure boats was resumed without any major plant changes.

The exclusive rights to manufacture the Herreshoff Bull’s Eye (12-1/2 footer), the Herreshoff Fish Class, The Herreshoff S-Class and other one-design boats were purchased in 1947. The jigs, forms and patterns formerly used at the Herreshoff Mfg. Co. were moved to Wareham together with their parts inventory, metal patterns and special machines. The President, R.F. Haffenreffer and General Manager, C.W. Haffenreffer of the Herreshoff Mfg. Co., were extremely anxious to transfer the Herreshoff boat building art together with more tangible assets to Cape Cod.

To have been selected from among many applicants to continue the construction of the Herreshoff boats is a source of pride at Cape Cod. We were also fortunate to have Sidney Herreshoff (son of Captain Nat) on our staff as consulting Navy Architect and Engineer for over 20 years.

In January 1949, after 50 years of building wood boats, Cape Cod joined one or two other companies in pioneering fiberglass boat construction. Shortly thereafter, a molding room was built and equipped and wood boat construction was discontinued.

About 1947, aluminum began to replace wood as spar material, and Cape Cod was among the first to accept these new aluminum spars as standard equipment for new classes. Zephyr Products, Inc., one of the first aluminum stock spar manufacturers, was purchased by the present management. Zephyr, having merged with Cape Cod, is now known as Zephyr Products Division of Cape Cod Shipbuilding. It has grown rapidly and supplies not only spars for Cape Cod boats, but also custom builds for other manufacturers and individual boat builders.

In 1979 Gordon L. Goodwin was promoted to President of Cape Cod Shipbuilding Co. , taking over from his father, E.L. Goodwin. The firm has a 100 years of boating experience, and is the oldest American sailboat builder.

With the experience and background of the personnel, Cape Cod will retain its position in the field as a quality shipyard by giving year round employment; therefore, producing boats that are simply better.
