Currently im not aware of any options to stop ships from crossing land borders on the Lands plugin

Describe the solution you'd like
Option to respect land borders from the Lands plugin in the config, perhaps making the air/water within act like an obstacle that prevents the ship from moving; "There are blocks in the way". When trusted, the ship would be able to move inside. I'm not too knowledgeable on this, so im not sure of any alternative methods.
