well this is definitely becoming an issue when big players aren't making sails do to lack of R maps ...i suggest that u change the sailing all together and set it up like u have the sails set up basically u can only sit on the shore for 10 minutes at a time and only be able to sit there 3 times a day same as ur sailing sails take 10 minutes and u get 3 shots problem salved no one will attempt to block the seas by sitting on the shores if they have a time limit for the activity jus sayin
