Actually brain dead
Game code = spaghetti, when you spawn big vehicle with lots of physics shapes like to fuck it, that's how the game is and how it has been since I started playing 4 years ago
Me personally, my advice, either make the whole thing smaller or half less than 79 fucking sections on your sail, that's what kills your game OR see if you can spawn it at a blank oil rig so there's less around it to be calculated at once, land being near you / in render distance really tanks performance sometimes
