Investigation of the Resistance a Sailboat is Subjected to in the Case of Draft Changes Caused by Modifying the Powertrain

In our research, calculations were performed using the example of a specific ship when a modification was made to the powertrain of a vehicle. These results were used to observe whether the ship is expected to decelerate or the change in the draft is likely to cause stability problems. In recent years, the rules concerning the use of inland waterways by recreational crafts have been tightened for environmental reasons. In many cases, these restrictions affect the drive chain, making the workflow of the conversion involved frequent. In this case, it is extremely important for shipowners to know how the draft will change and at what speed the ship will operate after the conversion. This study on a numerical flow simulation provides an excellent opportunity to find out.
