structure from boat bugged on sea

sailing with two winged masts at full speed will cause some structure stuck on the sea sometimes

once structure at edge of boat can't follow movement change on boat, they stop synchro movement with the boat

and dispatch from your boat

this usually happen on chest, mast, fishing tin those tiny structure

this is more serious problem that winged mast is still able to affect boat's speed even it is not on the boat anymore

the structure movement and position should be fixed relatively with boat object IMO
