PropExpert makes it easy to find and use trial data. When doing a repower or considering a new propeller, it is recommended to base the speed prediction on a prior trial. Well, when we have a credible vessel trial with good match between all components, you can save this data into the PropExpert vessel database for future use. There is a relationship between vessel size, speed and power that conforms to what is commonly known as a geosim rule. The closer the size, shape and speed range between the two, the better the results.
Many users typically do the same type of hulls over and over.
In southern Florida, for example, users will perform many sizings for twin-screw motor yachts from the same builder. The hulls are very similar, but of different length and weight. Basing the speed prediction on a past trial of one of these vessels is a very successful technique if you do not have actual trial data in hand.
