The roll off points are already solved and are part of the patch that is released today. The issue is that naval factories do not guarantee that there is sufficient space around the factory to allow ships to leave the docks properly. Combine that with the hectic pathing of ships and you have a pathfinding mess that is frustrating, especially for larger ships.
Note that all other factories do make this guarantee, hence we in general experience no pathing issues with those except when we chuck it with 100 assisting engineers.
