Players kicked out of mod-provided boats

[cajlo]

Describe the bug
I'm using pyrotech mod. Pyrotech boats too expensive for early game, so I needed rafts.
I've tried PrimalBoat https://www.curseforge.com/minecraft/mc-mods/primal-boat
I've tried Just A Raft Boat https://www.curseforge.com/minecraft/mc-mods/just-a-raft-mod
I've deleted all other mods for tests
Both of them have strange behavior, when player enters boat, it is mounted for 2-5 seconds, then player is kicked out of the boat, and can't enter it anymore

To Reproduce
Steps to reproduce the behavior:

1. Install one of mods above
2. Sit in mod-provided boats
3. Check that you are on water-source block, solid blocks not cause error
4. See error, as you are kicked out from boat

Expected behavior
Keep mounting boat
