in a random map, a situation arises where you need to sail to another island... but when there are islands in the random map, all the main islands have a shipyard separate from the castle (in general, in a random map, shipyards that can be built in a castle are useless, since the castle is located in the center of the island)...
in other cases, the absence of a shipyard is a bug.
