Did that for a springbreak my senior yr of college. We rented a boat just like all the others from some guy that said he would drive the boat for us.....just call him in the morning when we wanted to leave. Thought this would be a good idea so we could all drink etc. The guy either didnt show up or showed up hrs after we called him. He sucked at driving and couldnt manuver the boat into the party cove like all the other people could...so the one day we actualy made it there we had to turn back around. Guy was a married pervert and wanted us to find him a girl more than half his age. Long story short he called the police on us after we told him how much he sucked and had us kicked off three days early.
