You can get the swimsuit on the beach (Southern part of the map). I don't understand you're 2nd question. Are you playing the public build? It doesn't have the pirate ship.
My game version is 1.0，I said the pirate ship refers to fucko's ship，fucko says: Do you want to visit this ship? (Mission not completed)，But I finished all the tasks on board, and I couldn't find the next task
That's the end of the public build. You can still go to the fire dungeon! There is a red crystal in the beach cave which will start a quest for the fire dungeon.
