Sinking Ship Plugin

I need some help with the sinking ship plugin!

I’ve started making a sinking ship game and I’ve installed a plugin because I couldn’t make the script for it.
So sometimes when I change the speed or the acceleration of a coordinate, the ship starts to bug ( in play mode )
I can’t upload any video about it unfortunately.

I tried with different types of welding. Sometimes it works with the same numbers but sometimes it’s not.

Thanks for any help!
