Hello, I have a boat with around 40k triangles (mesh part with bones), I was wondering how i can make it stop wiggling and shaking while its on water, I dont know if its because the character is on the ship or a part is colliding.

You need to make the boat Mass great enough that player movements donāt affect it too much.
Personally I make the section out of the water very low Density, then hang a CanCollide false Transparent ākeelā Part thatās has a high Density as deep as I can get it and still have it in water.
Another way is to put a Transparent CanCollide false Part with low density above the waterline and put the keel Part on it.
This ākeelā acts like a pendulum, keeping the boat upright, but increasing the overall Mass of the boat.

Thank you so much for the solution, I decided to make the stuff that isnt in the water have low density, and the parts in the water have high density, but it still kinda bugs and wiggles around which is very annoying.
How low are the Density of the parts above the waterline and the Parts below the waterline? Maybe try Massless for the Parts above (or just slightly below) the waterline, then in Test mode play with the Keel Density until the boat floats the way youād like.
The greater the overall Density of you boat the better, but not so much itāll sink below the water when players are on it. If the boat isnāt heavy then players will move it when they interact with it.
Terrain Water Density on Roblox is 1.

back on my main, its around 0.1 at the top, and 5 at the bottom
Maybe send a link or a picture with a Robloxian for scale so we can see how big is the model (in studs) just to get an idea of how much mass you are dealing with.
For example, if the boat is only 5 studs wide by 4 studs high and 12 studs long then itād be very tough to keep it stable and free of player movement.
You say itās 40k triangles so Iām guessing itās a little bit bigger than the size I mentioned.
Other alternatives are to add an AlignOrientation force (similar to the deprecated BodyGyro) to keep the boat level, or make the Density 5 keel much lower.
Another thing is to make sure your boat isnāt really narrow. If you have a wide flat heavy boat like a barge that itās going to be more stable than something like a canoe thatās narrow and light.
Alright, one second, Its around 50k triangles, ill try the alignorientation asap
