When running sensitivities with varying wind and current the tonnage of the vessel affects the dynamics of the vessel. Thanks to the recommendation of one of our users, we have added three tonnage ranges – low displacement (5 to 15 tons); medium displacement (16 to 40 tons); and, high displacement (41 to 60 tons). This will allow to model boats up to about 70 feet in length to be more accurately simulated. Select the tonnage at the start menu.
Please let us know if this is accurate!
