In naval architecture, a taffrail is the handrail around the open deck area toward the stern of a ship or boat. The rear deck of a ship is often called the afterdeck or poop deck. Not all ships have an afterdeck or poop deck. Sometimes taffrail refers to just the curved wooden top of the stern of a sailing man-of-war or East Indiaman ship.
A chip log consists of a wooden board attached to a line (the log-line). The log-line has a number of knots at uniform intervals. The log-line is wound on a reel so the user can easily pay it out. Over time, log construction standardized. The shape is a quarter circle, or quadrant with a radius of 5 inches (130 mm) or 6 inches (150 mm), [1] and ...
H. Taprell Dorling. Captain Henry Taprell Dorling (1883–1968) was a British sailor, author, and journalist who served in the Royal Navy during both World War One and World War Two, giving his marine fact and fiction a notable authenticity. His Pincher Martin, O.D. (1916) is widely referenced as the source for Pincher Martin (1956) by Nobel ...
Strake. A clinker-built Viking longship, whose overlapping planks constitute "strakes". On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost (at the bows) to the sternpost or transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side.
The stern is the back or aft -most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the ...
In naval architecture, an afterdeck or after deck, or sometimes the aftdeck, aft deck or a-deck is the open deck area toward the stern or aft back part of a ship or boat. The afterdeck can be used for a number of different purposes, yet not all ships have an afterdeck. In place of the afterdeck, a ship may be built with a poop deck, that is a ...
This unit uses a mercury-based manometer to measure the difference in static and dynamic water pressure. Pitometer logs (also known as pit logs) are devices used to measure a ship's speed relative to the water. They are used on both surface ships and submarines. Data from the pitometer log is usually fed directly into the ship's navigation system.
Shown are the whipstaff, the rowle, the tiller, the rudderstock, and the helmsman. A whipstaff is a steering device that was used on European sailing ships from the 14th to the 17th century. Its development preceded the invention of the more complex ship's wheel and followed the simple use of a tiller to control the steering of a ship underway.
