Coming back to the boat design options, I'd like to see the boat models be modular where you can modify the parts on the boats from a menu in game. We could have drop down menus with boat part options, so we can choose the parts we want. The boat could start out as sponsons, turn fin, rudder, propeller, strut and drive shaft and then you add the other parts. In HydroMod, we had four deck designs (modern turbine, older turbine/U13, Leland turbine and modern piston). Those could be the options for the deck designs. You could do that for all the options until you have a finished boat.
I know this may not be possible, but it would be nice to have.
