A padeye is a device often found on boats or ships that a line runs through or provides an attachment point. It is a kind of fairlead and often is bolted or welded to the deck or hull. It is also used in oil and gas projects to assist in the purpose of lifting.
In boating, a fender is an air-filled ball or a device in other shape and material used to absorb the kinetic energy of a boat or vessel berthing against a jetty, quay wall or other vessel. [1] Fenders, used on all types of vessels, from cargo ships to cruise ships , ferries and personal yachts , prevent damage to vessels and berthing structures.
The reason for this is that when the boat is level, the drain or other opening will always be above the waterline, and so water will only flow out. At sea, when the boat rolls in the waves, the opening may sometimes be below the waterline. If the seacock is open, water may flood the boat, causing it to sink. Sea valve at lower right
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 ...
Typical trim tabs on aileron, rudder and elevator. Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force.
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
Any mechanical components that can rust or corrode need regular cleaning or replacement due to the environment of high moisture and potentially heavy mineral deposits in areas with hard water. Evaporative media must be replaced on a regular basis to maintain cooling performance. Wood wool pads are inexpensive but require replacement every few ...
A keel cooler is a type of internal combustion engine cooling system used in marine engines.. In this system, engine coolant is circulated through a system of tubing outside the vessel's hull, using the lower temperature of seawater to reduce the coolant temperature via heat exchange before it is recirculated through the engine.
