Go-fast Boat

miami vice


A go-fast boat is a small, fast boat designed with a long narrow platform and a planing hull to enable it to reach high speeds. During the era of Prohibition, these boats joined the ranks of ‘rum-runners’ transferring illegal liquor from larger vessels waiting outside territorial waters to the mainland. The high speed of such craft enabled them to avoid interception by the Coast Guard. More recently the term ‘cigarette boat’ has become common.

The present era of cigarette boats, dating from the 1960s, owes much of their design to boats designed for offshore powerboat racing, particularly by designer and builder Donald Aronow. During this period, these boats were used by drug smugglers to transfer drugs across the Caribbean to the United States.

Seawise Giant

Seawise Giant

Seawise Giant, later ‘Happy Giant,’ ‘Jahre Viking,’ ‘Knock Nevis,’ ‘Oppama,’ and finally ‘Mont,’ was an Ultra Large Crude Carrier (ULCC) supertanker and the longest ship ever built. She possessed the greatest deadweight tonnage ever recorded.

Fully laden, her displacement was 724,239 tons, the heaviest ship of any kind, and with a draft of 81 ft (the distance between the waterline and the bottom of the hull), she was incapable of navigating the English Channel, the Suez Canal or the Panama Canal. Overall, she was generally considered the largest ship ever built, as well as the largest self-propelled human-made object ever built.

Submarine Aircraft Carrier


Submarine aircraft carriers are submarines equipped with fixed wing aircraft for observation or attack missions. These submarines saw their most extensive use during World War II, although their operational significance remained rather small.

The most famous of them were the Japanese I-400 class submarine and the French submarine Surcouf, although a few similar craft were built by other nations’ navies as well. Except for the I-400, submarine aircraft carriers used their aircraft in a supporting role (usually for reconnaissance), unlike the typical surface aircraft carrier, which describes a ship whose main function is serving as a base for combat aircraft.

Sen Toku I-400


The Sen Toku I-400-class Imperial Japanese Navy submarines were the largest submarines of World War II and remained the largest ever built until the construction of nuclear ballistic missile submarines in the 1960s. They were submarine aircraft carriers able to carry three Aichi M6A Seiran aircraft underwater to their destinations. They were designed to surface, launch the planes then dive again quickly before they were discovered. They also carried torpedoes for close-range combat. The I-400-class was designed with the range to travel anywhere in the world and return. A fleet of 18 boats was planned in 1942, of which only three were completed.

Located approximately amidships on the top deck was a cylindrical watertight aircraft hangar, 31 m (102 ft) long and 3.5 m (11 ft) in diameter. The outer access door could be opened hydraulically from within or manually from the outside by turning a large hand-wheel connected to a rack and spur gear. The door was made waterproof with a 51-millimeter-thick (2 in.) rubber gasket.

Flying Submarine



A flying submarine or submersible aircraft is a craft able both to fly or travel under water. The Soviet Union made an unsuccessful attempt at developing a flying submarine during World War II. In 1961 American engineer, Donald Reid designed and built a single-seat craft (32.83 ft length) capable of flight and underwater movement, the Reid Flying Submarine 1 (RSF-1). The first full-cycle flight [underwater at 6.5 feet (2 m) depth, airborne at 33 ft (10 m) altitude] was demonstrated on 9 June 1964.

The US Navy is looking at the Lockheed Martin Cormorant, a drone aircraft launched from a submarine. On launching it floats to the surface and after flight it is retrieved from the water surface; it cannot travel directly underwater. In 2008, DARPA announced that it was preparing to issue contracts for a submersible aircraft.

The Hobie TriFoiler is the fastest production sailboat ever created with a top speed of around 35 mph. Designed by the brothers Greg and Dan Ketterman, this trimaran has two sails, one on each ama, and hydrofoils that lift the hulls out of the water at speed. It lifts on the foils at wind speeds between 10 and 11 mph (18 km/h) and quickly accelerates to twice that speed in seconds.

The TriFoiler’s high price-tag ($12,900), fragility, and usage limited to winds between 10 and 25 mph (40 km/h) with low waves, led the Hobie Cat Company to discontinue production. Approximately 30 Trifoilers were built prior to production starting at Hobie in 1995 and another 170 were produced by Hobie before halt of production in 1999.
