One of the best vacations I had was cottage that about 200' from public launch. We would eat lunch on deck watching the "festivities". The absolute winner was a beautifully restored old wooden Lyman with I/O. These 2 morons begin to launch, forget to take tie downs off so boat floats trailer off to side. Oops! The bow line guy was screaming at driver and waving, jumping up and down! The driver didn't have windows down so it took some time. Finally pulls boat back up onto ramp, takes tie downs off and launch. Boat still doesn't come off trailer.! OMG! LMAO! Forgot bow hook! OMG you can't make this up. Now back on ramp, backs down and launches. The boat floats off hard and fast pulling the bow line guy right into the water.! My wife is falling out of deck chair, my son is damn near crying from laughing so hard. He gets back up swearing at the driver like a truck driver in a city. Everything calms down and the driver parks truck. Jumps into boat and boat won't crank! OMG! Lifts dog hatch and starts swearing! WTH? He is screaming no F'n battery! We can't eat now from holding stomachs laughing so hard!! He jumps out and gets battery out of truck. Hooks battery up all seems well.....uh oh. He starts cranking the motor and it won't start. I mentioned to wife he better air bilge by lifting dog hatch since old boats didn't have ventilators. Too late. Huge explosion! Ball of fire 10' into air and dog hatch is blown off boat and crazy but it landed about 25' from us in yard.! Boat totally consumed in fire, guy in back blown out of boat! He bobs up and ok. The driver turns around in shock sees it on fire and jumps out. I call 911 and report it. I ran over to ramp with fire extinguisher but too far gone. Huge black billowing cloud like a nuke went off! Fire boats showed up and fire trucks. I was on my dock wetting down my boat with its fresh water wash down system. I actually have a video of this fiasco and will look for it.
For Michigan guys, this was Pentwater lake quite a few years ago.
