A single hull boat has only one hull, which is the standard for boats. Catamarans have two, or twin hulls.

How does the shape of a boat's hull affect the speed?
How does hull shape affect the speed of a boat? When trying to get the most speed out of your boat, you may want to consider how the hull shape affects the speed of the boat. "Hydrodynamic" is a term that is used when determining the motion or flow of water. It is similar to the more familiar term "aerodynamic," which relates to the flow of air. The speed of a boat is correlated to its hydrodynamic efficiency, and the hydrodynamic efficiency is determined by the shape of the hull of the boat. The hull of the boat is the first area to be hit by water as you speed forward. A round or square hull will connect with the water like a force that is pushing against it. As the force of the water hits the boat hull straight on, the boat must push the water out of the way before it can attain optimal speed. This limitation of the boat's ability to get to a higher speed quickly is known as drag, and is affected by the hull shape. A boat hull shape that is pointed allows the water to flow around the boat quickly. The less water that the hull needs to move out of the way, the faster the boat will go. How hull shape affects the speed of a boat is one factor that the military had taken into consideration when they started to build the V-shape hull design. This shape offers the most hydrodynamic efficiency, which gives the military a boat that can cut across water with little drag and perform well at high speeds.

What is a planing hull?
A planning hull is a hull of a boat that has its weight supported more by hydrodynamic lift, rather than hydrostatic lift or buoyancy.These boats are built for speed.
What is the average speed of a motor boat?
There are to many variables that go into that question . Boat weight , motor size , prop pitch and diameter , form of the boats hull ( flat or a v hull ).
What is a charactristic of catamaran hull?
A catamaran is a boat with two hulls connected over the water. This design is very stable compared to single hull.
What is the maximum speed of a sailboat?
Maximum Speed of a Single-Hull Displacement Boat Hull Speed = 1.34 x the square root of the LWL LWL: length of the hull at the waterline. Please note: this is the theoretical maximum speed of a displacement monohull and does not take into account the following criteria: 1. Hull Design - each hull's contours will effect the laminar flow, that is how smoothly and effortlessly the water flows over it. Every design has a certain co-efficient of drag, and depending on the hull, more or less inherent and induced drag. 2. Displacement - just like with a car, the lighter you make a boat, the faster you can make it go. 3. Sail Area/Displacement Ratio - this is a bit like the power/weight ratio in a car. Since the sails are pushing the boat through the water, the heavier the boat, the larger the sails will have to be in order to take maximum advantage of the hull speed formula. If two vessels have the same hull design and the same sail area, the one with the lower displacement will be the faster vessel. 4. Type of Keel - there are two main types of keels, full and fin. Full means that the keel runs the length of the underside of the hull and fin is just what it sounds like - a fin placed roughly amidships. Depending on the weight and shape of the keel the boat will move faster or slower. If you want to know the hull speed of a particular make and model of boat, see if you can find a polar diagram. Polar diagrams, or plots show the speed of the hull at various points of sail and with various wind velocities.
What is a hull on a boat?
The hull on a boat is the body of it. It is watertight so that no water leaks in and sinks the boat.
How fast is a 10 hp boat boat?
The shape of the boat hull, the gearing, the propeller size and pitch, the draught, the tide all influence the speed a vessel will travel.
What limits the speed of boat?
Type your answer here... Mainly engine size, overall weight, hull design.
Where is the hull identification number on a boat?
On the hull
What does 1.34 SQRTLWL mean when referring to hull speed?
The Hull Speed of a boat, usually referring to a displacement boat (ie, a fuel efficient or slow moving boat), is very closely approximated by the Square Root (SQRT) of the LWL (Length Water Line) multiplied by 1.34. That is - a boat with an 81 foot waterline (about 95' overall (LOA = Length Over All)) will have a hull speed of SQRT(81) * 1.34 = 9 * 1.34 = 12.06 Nautical Miles per Hour, or "Knots".
