Your dumbest mistakes on the water. I made mine today.

Two I can think of that really hurt. 

Snagged a savage gear swimbait from shore, so I could not retrieve it from the snag (breaking off 20lb CXX was fun...)

Spoiled a spool of 20lb Sniper with a backlash when I smacked the lure into the water at the beginning of  a cast.

These are some good stories!  Some are borderline insane, some are complete stupidity, but they are all entertaining.

A lot of people have forgotten to put their plug in the boat.  A new law last year in MN requires boats to be hauled around while on trailer with the plug out so it is evidently taking people a while to remember to put them back in when they get to the access.

Last summer when it was raining at a steep concrete ramp, I saw a big 20 foot fiberglass deep V Ranger walleye tournament boat load up on the trailer.  The individual in the boat failed to hook up the strap in front after he power loaded it and when the driver stepped on the gas to pull it out of the water, the whole boat slid back and landed on the concrete.  SMACK

Every trip I usually do something embarassing, I get too excited to be on the water and don't think things through.

Last trip I was retying, cut the main line (not the tag end) and tossed the tube over the boat into the water. I picked up my rod to make a cast and my tube was gone.

I hate spider, those wind knots kill me.

Started using baitcasters this year myself.

Whenever it tangles i just cut it all out and re spool.

One of my dumbest moments and coolest moments occurred on the same day. Every once in a while you may be glad you have a reel rigged with #50 spiderwire braid. I was launching my boat by myself, for some reason I wasn't paying enough attention and backed too far and too fast down the dock. I realized and hit my brakes. My jeep stopped, the trailer stopped, the boat however did not. As I watched it slowly floating into the lake, I contemplated jumping in and swimming to it when I remembered that I had a catfish rod in my jeep rigged with #50 Spiderwire. I grabbed it and it already had a treble hook and sinkers on it and I started casting towards my boat. The fourth cast hit in the middle of the boat and snagged the carpet (Luckily I had chosen to use carpet from Lowes instead of marine carpet, I probably would have never snagged it if I had). I slowly and carefully reeled/pulled my boat back to the ramp. From that day on, I tie a rope to the cleat and to the back of my Jeep every time I launch the boat by myself.
