Carlson CEC of the War Plans Office came up with the concept of NLPs in 1935, [ 1 ] but it was in 1940 that the US Navy looked at the idea more seriously.
Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
Two additional chambers, located below the gunwale on either side and called "speed skags," provide cushioning for the boat's occupants and additional buoyancy in case of pressure loss in the hull. The final chamber is an inflatable keel tube which runs the length of the craft and gives the bottom of the hull a "V" shape, imparting directional ...
Other types feature a casing under the boat, which does not take up space but instead has the problem of increased drag. For this reason, it is not uncommon to find boats with a combination of shallow keel and centreboard (e.g. Randmeer). The keel provides the housing for the centreboard, moving it out of the hull, but adds only a small amount ...
A padeye is a device often found on boats or ships that a line runs through or provides an attachment point. It is a kind of fairlead and often is bolted or welded to the deck or hull. It is also used in oil and gas projects to assist in the purpose of lifting.
Only the leeward side leeboard is used at any time, as it submerges when the boat heels under the force of the wind. A disadvantage, where there is an inadequate fixed keel, is that they typically ship (bear) little ballast, which being on the far side delays the onset of unballasted craft's heeling, that is, to put up a good, constant ...
