custom boats and aircrafts

i would like to see custom vehicles get into the game picture this your on a ship with your crew and BAM cannon fire from anther ship just hit your boat and now a hole is in your ship you go down to repair while your crew fights off the other ship you sink the other ship and win the battle. also i would like to see cannons for pvp as well it would work like this your vehicle would have a core and a seat for contol (wheel.cockpit.ect) if your core breaks than your vehicle explodes also it wold make underwater tavel easer
