Edelbrock carburetor question?
Nice call Science Teacher. While there are many catamaran style sailboats there are also fast ferries with a dual hull design. There are even some rowing hulls with catamaran designs.What vessel is best suited for a life permanently at sea? would a hovercraft be.?
A catamaran is a vessel with two distinct hulls.
This dual hull design allows for a large deck area with a smaller submerged hull area. The vessel also tends to be lighter than a mono-hull counterpart would be. This means a boat can go faster with the same amount of power. (There's less resistance.)
Catamaran sail boats may have more trouble turning due to the reduced weight.
It is a two hull sail boat with a mast mounted on a transverse frame joining the two hulls. Three hull models are called Trimarans.
What can me and my friend do at our party?
i've go one.. com on over... ok just messing it is a split hulled sailing vesel for sport sailing it has usually two hulls sometime 3 and connected buy a attaching pieces between the hulls, with a center mast. for the sail.Is it OK to buy a saltwater yacht?
It is a 2 hulled boat. It can be sail or power. Any boat with 2 hulls is considered a catamaran.Want to travel to canada by boat scared of flying . how do i do it from uk?
A catamaran (from Tamil kattu "to tie" and maram "wood, tree") is a type of boat or ship consisting of two hulls joined by a frame. Catamarans can be sail- or engine-powered. The catamaran was the invention of the paravas, a fishing community in the southern coast of Tamil Nadu, India. Catamarans were used by the ancient Tamil Chola dynasty as early as the 5th century AD for moving their fleets to conquer such Southeast Asian regions as Burma, Indonesia and Malaysia.Catamarans are a relatively recent design of boat for both leisure and sport sailing, although they have been used for millennia in Oceania, where Polynesian catamarans and outrigger canoes allowed seafaring Polynesians to settle the world's most far-flung islands. Catamarans have been met by a degree of scepticism from some sailors accustomed to more "traditional" designs.
Can any one help me with information on how to ship salvage cars from L.A. port to El salvador?
Although the principles of sailing are the same for both catamarans and monohulls, there are some "peculiarities"to sailing catamarans. For example:

Catamarans can be harder to tack (turn through the wind). Because they are lighter in proportion to their sail size, they have less momentum to carry them through the turn when they are head to wind. Correct use of the jib sail is often essential in successfully completing a tack without ending up stuck in irons (pointing dead into the wind and sailing backwards, see: No Go Zone).
They have a higher average speed.
Catamarans are less likely to capsize in the classic 'beam-wise' manner but often have a tendency to 'pole-axe' (or 'pitchpole') instead - where the leeward (downwind) bow sinks into the water and the boat 'trips' over forward, leading to a capsize.
Teaching for new sailors is usually carried out in monohulls as they are thought easier to learn to sail, a mixture of all the differences mentioned probably contributes to this.
Do you know anything about inflatable bags used for marine salvage?
Catamarans, and multihulls in general, are normally faster than single-hull boats for four reasons:
Information on the mv derbyshire shipwreck?
each hull of a catamaran is (typically) thinner in cross section than those of monohulls;
catamarans are lighter due to the fact there is no keel counterweight.
catamarans have a wider beam (the distance from one side of the boat to the other), which makes them more stable and therefore able to carry more sail area per unit of length than an equivalent monohull.
the greater stability means that the sail is more likely to stay upright in a gust, drawing more power than a monohull's sail which is more likely to heel (lean) over.
A catamaran is most likely to achieve its maximum speed when its forward motion is not unduly disturbed by wave action. This is achieved in waters where the wavelength of the waves is somewhat greater than the waterline length of the hulls, or it is achieved by the design piercing the waves. In either case pitching (rocking horse-like motion) is reduced. This has led to it being said that catamarans are especially favourable in coastal waters, where the often sheltered waters permit the boat to reach and maintain its maximum speed.
How much off MSRP can you expect to pay for a boat?
Catamarans make good cruising and long distance boats: The Race (around the world, in 2001) was won by the giant catamaran Club Med skippered by Grant Dalton. It went round the earth in 62 days at an average speed of eighteen knots.
