Sunnie

I lost 3 boats this way in 15min, one wasn't even near land.

First: I was out in open water and saw a sunken ship, so I stopped above it, jumped out of the boat and dove down to look for chests. When I came back up, my boat was gone. 

Second: I saw an amethyst geode and dove down to look in it. When I came back up, my boat was gone.

Third: I was approaching my local base, went right up to the land with my boat and hit spacebar to exit, and the boat disappeared immediately. I tried hitting the space I knew it had been with my axe and sword, and couldn't find it.
