If you jump to get onto your boat and your character enters the diving animation, it will continue the animation and float into the air if you use the teleport to helm command.

Steps to reproduce:

1) Park ship just outside of jumping range.

2) Do a running jump towards ship that results in a diving animation (repeat until diving animation achieved).

3) While underwater and in the animation click the ship anchor button to teleport to helm of ship.

4) At this point your character should be flying above the ship in the diving animation until they finish the animation and land.
