Large boats can have as many as four batangan for each outrigger. The floats are slightly diagonal, with the front tips wider apart than the rear tips. The front tips of the floats also extend past the prow and curve upwards, while the rear tips do not extend beyond the stern. Additional booms (sa'am) also extend out from the hull and the main ...
Planing hulls: planing hulls have a shape that allows the boat to rise out of the water as the speed increases. Sail boats that plane are typical V-shaped at the bows and flat-bottomed aft. Hydroplanes are very light, flat bottomed, high powered speed boats that plane easily on flat water, but they become unstable in rough water.
The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. The earliest evidence of maritime transport by modern humans is the settlement of Australia between 50,000 and 60,000 years ago. This almost certainly involved rafts, possibly equipped with some sort of sail.
Ancient boat building methods can be categorized as one of hide, log, sewn, lashed-plank, clinker (and reverse-clinker), shell-first, and frame-first. While the frame-first technique dominates the modern ship construction industry , the ancients relied primarily on the other techniques to build their watercraft.
A bulb alone forces the water to flow up and over it forming a trough. Thus, if a bulb is added to a conventional bow at the proper position, the bulb trough coincides with the crest of the bow wave, and the two cancel out, reducing the vessel's wake. While inducing another wave stream saps energy from the ship, cancelling out the second wave ...
In the late 1970s, the Soviets realised the need for a larger, more seaworthy craft with better gun armament and higher positioned air search radars.In the Tarantul class, both the single 76 mm (3.0 in) main gun and the two 30 mm (1.2 in) Gatling-type guns are used for air defence, together with a comprehensive electronic warfare suite.
The boats of HMS London were kept at five minutes' notice, ready equipped with water, salt pork, biscuits, arms, local currency and a small cask of rum. Manned by eight or nine sailors, with a midshipman or junior lieutenant in command, a boat was often away from the London for two or three weeks, normally anchoring every night, the men off ...
