Boat dissapears/ deleted from realm unexpectedly

[[EDIT: I have to relog into the realm for it to respawn/reload/reappear]]

Boats that I get into disappear shortly after getting out of them.  There doesn't seem to be a collision, they're just not there anymore.

It might have to do with me mashing the space bar shortly after pressing the CTRL button (to get out of the boat).  I do this so I can attempt to jump out of the boat and not get stuck as usual, which is a secondary problem of course.

Ctrl, then rapidly and shortly afterward spacebar (jump) mashing + trying to move forward

I'm always in open water when doing so; not up against a block.
