Couple of things I would put forward for possible revision

Inside the boat you do get cues to the amount of damage taken. But it may not be obvious. The cues inside are bursting and no longer working lightbulbs. You have only so many that can fail before it's done and over. But agreed, you don't get them outside on the deck. Well except from the obvious impact explosion. That should give enough of a cue to dive. It's not a tank with armor that you are driving, right!?! Do whatever your playstyle is like. But don't expect to live long enough.
