I've tested the new code using your ferries. No wiggles here that I can see, however the ships now have a default turning radius of 2000ft (adjustable in the scenario file) in the revised code. This radius also varies according to speed. The ship rolls reasonably realistically in the turn. Acceleration is also realistically modelled When testing using your "flightplan" the ferries run into the coast, so either the waypoints are badly placed, or they need adjusting to allow for realistic turning radii, or the coast has moved. This last is possible as we recently changed the mapping of coasts in general. If you want a flightplan to repeat, you leave off the END item in the flightplan, and set <repeat>true</repeat>. The last entry in the old flightplan become the first in the repeated plan so you need to allow for this.
