It is proved for entertainment only and not intended to be used for any other purpose. Commercial use for any reason is prohibited. Mercury Marine uses the following formula to estimate potential top endthis calculator uses this formula.
The calculator below uses the above formula. By using known values for the weight, power and speed you can come up with speed of boat in still water calculator uk more accurate constant for your boat. You can then see what effect changes to weight or power will have on top speed. Using the calculator in this fashion will produce surprisingly accurate results. Just remember there is no substitute for accurate testing!
If you don't have Internet access on your boat, Mercury has a neat slide rule that makes all this easy. Accurate data is important when using this calculator. Weights should be actual running weight as determined by a speed of boat in still water calculator uk and are to include driver, fuel, engines, supplies. We have found manufactures published weight to be unsuitable for these calculations. Shaft horsepower is to be the actual uncorrected engine horsepower less drive train losses.

First, it is important to have accurate speed and RPM information. This is critical for the best results! If you are serious about getting the most performance out of your boat, invest in accurate instruments. We have found Gaffrig speedometers to be the most accurate. We prefer digital tachometers, especially for testing. Think of a prop as screw. The pitch is the theoretical distance speed of boat in still water calculator uk prop should move through the water in 1 revolution.
A 24" pitch prop would move 2 feet. Slip is figured by comparing this theoretical speed to the actual measured speed. By the way, for these calculations, add 1" to the pitch if your prop is cupped. Just about all hi-performance props are. For the purpose of this test, we are looking for the absolute fastest boat speed. So trim the boat by the Lorem lpsum 317 boatplans/questions/mathematics-question-answer-app-02 just click for source Assuming we are in the ball park, and do not have to worry about over revving the engines, ignore the tachs for the moment.
If this is your first test of a new package you do Lorem lpsum 317 boatplans/fishing/catamaran-fishing-boat-with-cabin-review catamaran fishing with cabin review to watch the RPM, and you might not be able to test at full throttle. DO NOT over rev. Check with speed of boat in still water calculator uk engine manufacturer for maximum RPM. Try increasing and lowering the trim until you find the fastest mph on your GPS or Speedo. Now look at the tach, and make notes of the trim position, rpm and speed.
You can repeat this at any throttle setting or speed. In fact you may be more interested in your cruising speed than top end. The highest RPM is not necessarily the fastest speed! When you get back to the dock, pull out your trusty or rusty if you are like me calculator and do the following: Figure your theoretical speed from above, subtract you actual speed.
Divide this difference by the actual speed. The number you speed of boat in still water calculator uk is your slip percentage. Most hi performance applications will be between 7 and 12 percent. Mercury has a handy slide rule type calculator available to do the math. Contact us for the part number and availability if you are interested. Now that you know the slip, what does it mean? Use this speed calculator to easily calculate the average speed, distance travelled and the trip duration of a vehicle: car, bus, train, bike, motorcycle, plane.
Works with miles, feet, kilometers, meters. You will need to convert the metrics to the same time and distance units, e. For example, if you have speed in Speed Of Boat In Still Water Calculator Facebook mph miles per hourtime should also be in hours. The unit of the result will depend on the units you input, but our speed calculator will conveniently display additional units where appropriate.
As noted above, make sure you convert the units appropriately first, or use our speed calculator which does that automatically. The resulting unit will depend on the units for both time and distance, so if your input was in miles and hours, the speed will be in mph. Example: If you took a plane from New York to Los Angeles and the flight was 5 hours of air time, what was the speed of the plane, given that the flight path was miles?
As usual, make sure that the time unit of the speed Speed Of Boat In Still Water Calculator 09 measure is the same as the time unit for the duration of the trip. Our distance calculator will sometimes output the distance in more than one unit, for your convenience. Example: If a truck travelled at an average speed of 80 km per hour for 4 hours, how many miles did it cover in that time? Speed of boat in still water calculator uk time, or more precisely, the duration of the trip, can be calculated knowing the distance and the average speed using the formula:.
Make sure you convert the units so both their distance and time components match, or use our trip duration calculator above which will handle conversions automatically. The time unit of the result will match the time unit of the speed measure, so if it is measured in something per hour, the result will be in hours. If it is measured in some unit per second, the result will be in seconds. Example: If a train can travel miles with an average speed of 50 miles per hour, how long it would take it to complete a mile route?
Say you travelled a certain distance with Speed Of Boat In Still Water Calculator In China a car or another Lorem lpsum 317 boatplans/sailing-boat/sailing-zingaro-new-boat-tour sailing new boat tour and you want to calculate what its average speed. The easiest way to do that would be by using the speed, distance, and time calculator above, but if you prefer, you can also do the math.
Either way, you need to know the distance to a satisfactory approximation, for which you can use a map e. Google Maps to measure the distance from point to point. Make sure you measure closely to the path you took, and not via a straight line, unless you travelled by air in which case that would be a good approximation. Of course, having a GPS reading of the distance would be more precise.
Then you need to know the travel time. Make sure you subtract any rests or stops you made from the total trip duration.

For a boat hulla simple way to think of theoretical boat speed is that a vessel is limited by the wave that boats hull creates. Going faster than the theoretical hull speed is possible, but the wave moves under the transom so the boat has to plow through the water at an angle, bow up which then requires exponentially more power to move the vessel once theoretical hull speed is reached.
This is the limit to displacement boat speed. A displacement boats theoretical hull speed is when the wave length is equal to the waterline length.
The important thing here is the length of the wave is relative to the length of the boat. Lorem lpsum 317 boatplans/boat-plans/sailboat-vector-art-rank Sailboat vector art SL Ratio is a speed of boat in still water calculator uk formula for calculating displacement boats speed which is typically 1. Not all hulls are the same; depending on other factors like displacement and beam the boat may create a larger or smaller bow wave in proportion to its length.
Heavier displacement vessels will have difficulty getting over 1. This formula applied to planing boats only and only takes into account the displacement of the hull, ignoring length. This may seem odd but as opposed to a displacement hull, the most important factor in determining speed is displacement. These two characteristics apply to the planing hull.
See Planing Hull for details. This chart represents the speed a traditional displacement hull can reasonably attain. Catamaran hull speed, trimaran hull speed and light displacement hull speed may be higher. The results and the chart plot are based on an SL Ratio of 1. Note that this number only applies to displacement hulls.
Hull speed, as calculated here, is important as it is a building block to attaining figures like, what power is required and ultimately calculating what propeller may Lorem lpsum 317 boatplans/pdf/fishing-boats-for-sale-washington-state-pdf �������� fishing boats for sale washington state pdf ������ optimum for a particular boat.
The chart displays speed at different percentages of theoretical hull speed. This speed calculator is a tool that helps you determine the average speed of a moving object based on the distance traveled over a certain time traveled.
