First if youre gonna make a floating boat model make sure it can take damage and if someone wants to help you script it if its deformed it can leak and slowly take on water and dip where its sinking. If done correctly there will be almost zero lag and you can make boats larger enough to walk inside of. It will require a bubble like shape/hitbox that cuts out a section of the water so you can walk and ride in below the water surface without too much fuss if any fuss at all due to the 2000 hz refresh rate. Take advantage of that and hopefully there will be submarine mods too. Little subs and big subs(not meshslaps) in the game would be amazing. Note: damaged physical bodies or hulls... Will self damage under extreme pressure. So it could become a case of damage making the vessel drag lower in the water... And it may force the hole open more... Etc causing an exponential issue that causes the boat model to slip under and instability. Be mindful of that.
