A sailboat without a sail is but a hull of itself.
A rough estimate of hull speed in knots is 1.34 times the square root of the length at the waterline in feet. The Catalina 22 has a 19 foot waterline, leading to an estimated hull speed of 5.8 knots
The highest sailboat speeds are by "non-displacement hull" sailboats, such as catamarans and trimarans. The world record speed attained, by official records, is 64 miles per hour for a trimaran.
round bottom hull
As a general rule, catamarans have a higher average speed than mono-hull sailboats. Catamarans are not the fastest sailboat, only sailboats that are know for their speed. In fact the fastest type of sailboat that is available is actually a trimaran; however there is a new design that is currently in the finaly stages of development called the monosailor, when testing is done it is believed that the top speed will reach over 100knts all by wind power.
It depends on many factors. The hull shape, how the sails are rigged, how much sail area you have, the ability of the crew, the wind speed, the tide.
maximum speed (hull speed) with a displacement hull with a 25ft waterline would be 6.75 knots or 7.76 mph. You 25 ft boat may have a shorter waterline, thus be a little slower.
That depends on what length Sunfish you are referring to.
The hull of a boat is the body of the boat. it is the part of the boat in the water. excluding the mast, boom, sail, rudder, keel, etc.
Wind and Water are the main elements that help the boat to sail. Water helps the barge or hull to push forward and the wind gives extra speed.
A sailboat will have positive buoyancy if the weight of the boat is less than the weight of the water it takes the place of. The weight of the water that is being occupied by the hull is displacement.
Maintain present course and speed.
A displacement hull always displaces an amount of water equal to the weight of the boat. A planing hull at a certain speed, will begin PLANING and rise partly out of the water, forced up by its v shaped hull, and only be displacing an amount of water equal to partial weight of the boat. A large ship, a tugboat, a barge, or a sailboat are displacement hulls. A speedboat or a jetski are planing hulls.
Hi There is not an average speed. It depends on the length and wind direction and speed
Hull speed is the theoretical limit of a sailcraft's speed. It can be approximated by the following formula: 1.34 * SQRT(LWL), where LWL is the length of the waterline, in feet. As a small vessel approaches its hull speed, the hull begins to climb its own bow wave. The faster the vessel tries to go, the more difficult climbing the bow wave becomes. Eventually, should the hull type permit it, the hull will begin to hydroplane (skimming across the water.
Speed up to pass in front of the sailboat
------------------------ A sailboat's speed is directly proportional to wind speed and hull design. The longest distance in 24 hours and the fastest circumnavigation are currently held by a trimaran and the short-course speed record is currently is currently held by a multihull built specifically for the attempt. For you and I sailing our fiberglass monohulls on the weekends, we are having a great day if we hit 10 or 12 knots. ------------------------ A sailboat can reach 30 miles per hour. There are two general types of sailboats, displacement type (monohull) and non-displacement type (catamarans, trimarans). The top speed of a displacement sailboat is based upon its waterline length because it sits in the water and cannot climb above the wall of water in front of it as it travels. This is calculated by taking the square root of its waterline length and multiplying by 1.3. The top speed of a non-displacement sailboat is limited by the sailboat design, the speed of the wind, and their point of sail - these sailboats can go much faster than the speed of the wind that is powering them, and are the fastest sailboats.
The Hughes plant burned down in 1991, I understand with all molds.
Some water in the hull is inevitable; that's why bilge pumps and bailing buckets were invented. But a constant inflow of water is a bad sign; you may have a leak somewhere.
Depends. Size is not the predominant factor when determining speed for a sailboat. Depends on the wind condidtions
A single hull boat has only one hull, which is the standard for boats. Catamarans have two, or twin hulls.
the mast and some ropes The sail is attached to the mast, which is in turn supported by stays (lines running from the mast fore and aft to the hull) and shrouds (lines running from the mast to the sides of the hull).
The sailboat operator is the stand-on vessel so they should keep their course and speed while the PWC is the give-away vessel so it should change course and speed.
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.
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.
