The British Royal Navy adopted and standardized on the Robinson's Disengaging Gear in 1881, [3] and this system was still in use in the late 20th century. The Robinson's Disengaging Gear consists of three mechanisms. There are two disengaging hooks, one at each end of the seaboat, holding the boat to the falls.
The length overall, including the bowsprit and aft boomkin, is 43.00 ft (13.11 m), while the length on deck is 34.00 ft (10.36 m). The boat has a draft of 5.08 ft (1.55 m) with the standard keel. [1] The boat is fitted with a Japanese Yanmar diesel engine of 40 hp (30 kW) for docking and manoeuvring. The fuel tank holds 60 U.S. gallons (230 L ...
Draft angle design is an important factor when designing plastic parts. Because of shrinkage of plastic material, injection molded parts have a tendency to shrink onto a core. This creates higher contact pressure on the core surface and increases friction between the core and the part, thus making ejection of the part from the mold difficult.
By contrast the vane gear offers at least the possibility of an improvised repair at sea, and can usually be rebuilt on land using non-specific parts (sometimes plumbing parts) by a local welder or machinist [citation needed]. To minimize the speed loss by the self steering gear it is essential to have the vessel's sails balanced with little ...
The boat has a PHRF racing average handicap of 144 with a high of 165 and low of 135. [1] [6] Catalina 34 WK Wing Keel model introduced in 1985, with a draft of 3.83 ft (1.17 m) with the wing keel. It displaces 12,550 lb (5,693 kg). The boat has a PHRF racing average handicap of 153 with a high of 159 and low of 150. [1] [7] Catalina 34 TM WK
Diagram of the steering gear of an 18th- to 19th-century sailing ship [3]: 151 Helm of TS Golden Bear. A ship's wheel is composed of eight cylindrical wooden spokes (though sometimes as few as six or as many as ten or twelve depending on the wheel's size and how much force is needed to turn it.) shaped like balusters and all joined at a central wooden hub or nave (sometimes covered with a ...
Drilling riser joints with buoyancy modules. A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. Drilling risers are categorised into two types: marine drilling risers used with subsea blowout preventer (BOP) and generally used by floating drilling vessels; and tie-back drilling risers used with a surface BOP and generally ...
Cal Yachts (also known as Jensen Marine and Cal Boats) was a manufacturer of performance oriented fiberglass sailboats from the 1960s to the 1980s. The Costa Mesa , California , headquartered company was founded in 1957, among the earliest of all-fiberglass, mass-production sailboat builders.
