The structure of tributyltin oxide: the most common TBT compound used in marine paint Biofouling on the hull of a boat. Tributyltin (TBT) is an umbrella term for a class of organotin compounds which contain the (C 4 H 9) 3 Sn group, with a prominent example being tributyltin oxide. [1]
The multi-chine hull approximates a curved hull form. It has less drag than a flat-bottom boat. Multi chines are more complex to build but produce a more seaworthy hull form. They are usually displacement hulls. V or arc-bottom chine boats have a V shape between 6° and 23°. This is called the deadrise angle. The flatter shape of a 6-degree ...
The stern is opposite the bow, the outside (offboard) of the front of the boat. The term derives from the Old English æftan (“behind”). Adrift: floating in the water without propulsion. Aground: resting on the shore or wedged against the sea floor. [3] Ahull: with sails furled and helm lashed alee. [4] Alee: on or toward the lee (the ...
The metal sheathing of Cutty Sark, made from the copper alloy Muntz metal. Copper sheathing is a method for protecting the hull of a wooden vessel from attack by shipworm, barnacles and other marine growth through the use of copper plates affixed to the surface of the hull, below the waterline.
There are several educational paths to becoming a marine engineer, all of which includes earning a university or college degree, such as a Bachelor of Engineering (B.Eng. or B.E.), Bachelor of Science (B.Sc. or B.S.), Bachelor of Technology (B.Tech.), Bachelor of Technology Management and Marine Engineering (B.TecMan & MarEng), or a Bachelor of Applied Science (B.A.Sc.) in Marine Engineering.
Waterline of a ship. The mark above the waterline indicates the Plimsoll line. The waterline is the line where the hull of a ship meets the surface of the water.. A waterline can also refer to any line on a ship's hull that is parallel to the water's surface when the ship is afloat in a level trimmed position.
A structural keel is the bottom-most structural member around which the hull of a ship is built. The keel runs along the centerline of the ship, from the bow to the stern . The keel is often the first part of a ship's hull to be constructed, and laying the keel , or placing the keel in the cradle where the ship will be built, may mark the start ...
A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". [1] That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed.
