I am making the player float in water, what type of Body will I use?

I was scripting a thing, but I used BodyGyro then I used BodyThrust and it ends up adding the player have like a gravity when jumps. What will I use? BodyPosition? Also I am using debounce to stop spamming but when someone touched the ocean instead the other player will fall. So I removed it but it ends up spamming a lot of BodyGyro's...
