The answer would be completely different depending on how the vessel is powered, and the type of water you're in, but I'll do what I can. If we cut down the variables by assuming you're on flat water:
PADDLE: Get the longest length/width ratio you can at the waterline. This is good for "tracking"(vessels tendency to stay moving straight), as well as minimising the effort needed to move max weight. If you push this ratio too far, the boat will be too tippy to stay upright, and/or your butt won't fit in it. Outriggers and rowing sculls are usually the fastest paddleboats, having length to width ratios over 10 to 1.
SAIL: Same as above, but also consider the additional factors like "self righting ability", "keel weight and it's traction at various heel pitches", "how the hull shape below waterline changes at heel". Remember that the freeboard, (hull above waterline) isn't really doing anything for hull performance except adding weight and catching wind, until it's in the water. You need a lot of things to sail that can increase drag, and a wider, more stable hull is good to have in a sailboat. A sailboat with a 10/1 hull ratio would capsize at the slightest breeze.
PROPS: Motorboat hulls are usually designed to plane. There are too many variables to list here, but I hope this horribly over-simplified version is helpful. Consider how the waterline will change at different speeds. If, while planing, the hull below water is as wide as it is long, you will lose tracking, and the steering will be dangerously touchy (this may be partly balanced out by the influence of inertia and weight, of course). That said, the less boat you have in the water, the less resistance you will have; so the fastest speedboat hulls are "hydroplaning" designs, that (once they reach a good speed) leave small sections in the water, having a length to width ratio over 8 to 1
All hull shapes also have a "max hull speed". The hullspeed is reached when the bow wave and/or stern wave causes so much drag that no amount of power can increase its speed. "Theoretical hull speed" is usually a mathematical estimation, and can be way off from an "actual hull speed".

Why is The shape of the hull on a barge different from the shape of a speedboat hull?
Barges are built for maximum weight bearing while other boats are built to move fast. Depth and shape of the hull is characteristic to the way the boat will be used and the speeds it will travel.
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 is the shape of a boat called?
The shape of a boat is referred to as its "hull." The hull is the watertight body of the boat that provides buoyancy and stability in the water. Different hull shapes, such as flat, round, or V-shaped, affect the boat's performance, speed, and handling characteristics.
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.
Why is a boat the shape it is?
The characteristics of water flow determine the shape of the hull; mainly resistance and turbulence.
What is the main part of the boat called?
Hull Is The Inside or bottom(?), and deck is the top. other than that i thinks its just called a boat. My best answer would be hull.
What makes the shape of a speed boat float?
A speed boat floats due to its hull design, which is shaped to displace water and create buoyancy. The hull shape allows the boat to stay afloat by pushing water aside as it moves through the water, creating an upward force that counteracts the force of gravity. Additionally, air compartments in the hull provide added buoyancy, helping the boat stay on the surface of the water.
How fast will a 10 hp out board go on a 12 foot aluminium boat v hull?
While the power of the engine affects the top speed of a boat, it does not determine the speed of the boat, as other factors influence the speed. Those include the shape and design of submerged part of the boat, the shape and design of the not submerged part of the boat, the wind and water conditions, the drive (gears, propeller, etc). While it is not possible to determine the top speed of this boat without more details, it is fair to say that it should go "pretty fast," as a 12 ft boat is not very large, and 10hp provide a fair amount of power for such a small boat.
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.
What is made by Vacuum Moulding?
Vacuum molding is the process of using a vacuum to suck a pliable material into a specified shape. For example, the plastic hull in a boat is made when the warmed plastic is pliable (shape can be altered for useful purposes) and is sucked up against a form in the shape the designer wants the hull of the boat to be in. While the vacuum holds the reshaped plastic hull against the form, the plastic cools and holds the new shape.
How does the shape make a boat float?
The shape of a boat with a hull that displaces water creates buoyancy. When the boat sits in water, the displaced water exerts an equal and opposite force on the boat, pushing it upwards. This buoyant force allows the boat to float on the water's surface.
Which simple machine helps a boat slice through water?
A simple machine that helps a boat slice through water is the hull of the boat. The shape of the hull reduces drag by allowing water to flow smoothly around it, making it easier for the boat to move forward with less resistance.
