In 1954 George Garcia, owner of Falls City Flying Service, introduced the ‘Marinette’ which was an aluminum houseboat initially built as a twin-hulled cruiser. Choosing to use an aluminum-magnesium alloy, whereas previous attempts at an aluminum watercraft had mainly involved small row boats made of a copper-aluminum alloy , the same ...
The grey area indicates the deck of the boat. A dorade box (also called a dorade vent , collector box , cowl vent , or simply a "ventilator") is a type of vent that permits the passage of air in and out of the cabin or engine room of a boat while keeping rain, spray, and sea wash out.
Werner Krüger (November 23, 1910 – October 21, 2003) was a German engineer who invented the Krueger flap in 1943. He evaluated Krueger (Krüger) flaps in the wind tunnels of Göttingen Aerodynamische Versuchsanstalt, AVA in 1944. Krueger flaps are aircraft lift enhancement devices fitted under the leading edge of an aircraft wing where a ...
Krueger flaps deployed from the leading edge of a Boeing 747 (top left and right in photo). Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Unlike slats or droop flaps, the main wing upper surface and its leading edge is not changed. Instead, a portion of the lower wing ...
The boat's hull and superstructure are constructed entirely from 5456 marine grade aluminum. [3] Designed with a hard chined deep "V" planing hull , [ 6 ] the 47′ MLB exceeds its hull speed . The frame is composed of 17 vertical bulkhead frames, each of which is welded to the deck and hull, and five of which are watertight.

The Landing Craft Air Cushion (LCAC) is a class of air-cushioned landing craft used by the United States Navy and the Japan Maritime Self-Defense Force (JMSDF). They transport weapons systems, equipment, cargo and personnel from ship to shore and across the beach.
An aerodynamically alleviated marine vehicle (AAMV) is a high speed marine vehicle configuration that uses aerodynamically generated forces to 'alleviate' its weight.The advantage is that the hydrodynamic lift required to sustain the weight of the vehicle is diminished, leading to a diminished hydrodynamic drag.
