Correct....nothing can be done to change that until they consider giving us the ability to changes the shape of the "spawn area". The way it was explained, regardless of where you put stations the game can't differentiate between land and water. Before I adjusted mine, I had boats in distress in the middle of the National Forest with no water for miles.......no wonder they were in distress.....stupid boat owners!!
The fact that they can't code to differentiate water and land, even with the OSM data available is a bit yikes
