Having spent my teenage years in a condo across from the 15th St boat ramp in Lauderdale, there is no greater entertainment than a boat ramp. The city should let boaters launch for free and charge spectators admission to the follies. Seen it all, the best reason for having your passengers exit the tow vehicle prior to launch is so the harbor police don't have to ask if anyone is still in the vehicle.
Once saw a tow cable (land based) snap that was attached to a 'combo-launch'(car/trailer/boat) and it came back, cut a nice 24" thick palm tree in two .... over a 100' away!
But the best were the low tide, two wheel drive types pulling out a twin I/O 23 footer and burning rubber until the tires popped .... the driver getting out to inspect the fact that, yes, there is no tire left (they always touch it, like their eyes are tricking them) and then (turning in disbelief) slipping on the algae and tumbling into the water.
Aahhh .... good times.
