Defender Class Torpedo Boat
The colonial service ''Defender''-class torpedo boats were designed by Thornycroft & Company for the defence of New Zealand, built at Chiswick in 1883 and shipped to New Zealand. They were quickly obsolete and were left to deteriorate ''in situ''. The remains of ''Defender'' are preserved at the Lyttelton Torpedo Boat Museum. Construction Acquired for the external defence of New Zealand, at a cost of about £3,200 each, all four boats were built and engined by John I. Thornycroft & Company at Church Wharf, Chiswick on the River Thames.Winfield (2004) p.316 Armament As built the class was armed with a single McEvoy spar torpedo, which was designed to be rammed into a vessel and explode beneath the waterline. A single 2-barrelled Nordenfelt gun comprised the total gun armament. The last pair had 18-inch Whitehead torpedoes fitted at build, and these were later retrofitted to ''Defender'' and ''Taiaroa''.

Spar Torpedo
A spar torpedo is a weapon consisting of a bomb placed at the end of a long pole, or spar, and attached to a boat. The weapon is used by running the end of the spar into the enemy ship. Spar torpedoes were often equipped with a barbed spear at the end, so it would stick to wooden Hull (watercraft), hulls. A Fuse (explosives), fuse could then be used to detonate it. Invention Robert Fulton had written about submarine (i.e., subsurface) marine torpedoes in 1810, and experiments were conducted using spar torpedoes that year. Boats carrying spar torpedoes were used during the War of 1812. E. C. Singer, a private engineer who worked on secret projects for the benefit of the Confederate States of America, constructed a spar torpedo during the American Civil War. His torpedo was detonated by means of a trigger mechanism adapted from a rifle lock (see flintlock mechanism for a similar device). The spring-loaded trigger was detonated by means of a long cord attached to the attacking ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defender-class Torpedo Boats
The Defender-class boat, also called Response Boat–Small (RB-S) and Response Boat–Homeland Security (RB-HS), is a standard boat introduced by the United States Coast Guard in 2002. The boats serve a variety of missions, including search and rescue, port security and law enforcement duties and replaces a variety of smaller non-standard boats. The design length of the hull is and the boat is officially referred to as such. However, the overall length with engines mounted is approximately . Powered by twin outboard motors, they are capable of speeds in excess of and have a range of , depending on the class. The boat requires a minimum crew of two persons, but has a carrying capacity for ten persons. The boat is easily trailerable and can be transported by a C-130 Hercules aircraft or truck. Although similar in appearance to a rigid-hulled inflatable boat, the Defender is actually an aluminium, aluminum-hulled vessel, equipped with a rigid foam-filled flotation collar. The f ...

Waterline
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. Hence, waterlines are a class of "ships lines" used to denote the shape of a hull in naval architecture lines plans. The load line (also known as Plimsoll line) is the waterline which indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy. For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length. In a sailing boat, the waterline length can change significantly as the boat heels, and can dynamically affect the speed of the boat. Aircraft In the aircraft design the term ''waterline'' designates a horizontal reference line used in alignment checks. The base line of the aircraft is designated as waterline 0 (zero). ...
