Re: Guy hit my boat on the water yesterday..
First, don't take legal advice over the internet, especially as far as procedures for suing, winning and collecting.
Second, if you do go to small claims court unrepresented, you'd better know youw law of evidence. For example, in Virginia, you can't use an estimate (hearsay) unless you get a specific affidavit from the repair shop (easy to do). You have to know those things in your own court.
Third, getting judgments is easy; collecting them is not. And procedures in one state (like Richard's description of Florida) are not necessarily the same in another (his are mostly all wrong for Virginia).
Fourth, file your insurance claim unless the deductible is high. Some of us self-insure with a high deductible.
Fifth, consider the criminal charge--what did he get cited for? when's court? are you going as a witness? because here's the deal: if he has done the right thing and paid your damages before court, the judge will likely let him off, but you don't care; you're paid. But on the other hand if he hasn't paid, he's likely to get a higher fine. So he has incentive to pay you first, and the courts like seeing things settle. Use it. (I can't give you specifics on how to do it; that would violate #1!)
Sixth, along the lines of #5: find out if the judge in the criminal case has the authority to order restitution. If so, what a win for you! You get a judgment and the state to pressure the collection! (I can't give you specifics on how to do it; that would violate #1!)
Seventh, Keep in mind that your time to do all this is (or should be) worth something. If court is 2 hours away, you miss at least one day of work, maybe 2 if he gets it continued the first time or the officer bumps it. Same with civil court. You'll eat up your $1000 repair bill right quick.
If you decide it's not worth chasing, just remind yourself that accidents happen to boats--I am NOT excusing this idiot--and you could have made some bone-headed move yourself and banged your boat against a piling or something. we all have.
