I remember one time a couple years ago on Mille Lacs, had my buddy (who doesn’t fish much) and his wife up for a fall smallmouth trip. My buddy backs me in at Mac’s, and his wife hooks the winch and chain from the tongue (she’s a trooper). I go to reverse off the trailer, and the boat doesn’t move. I reverse harder, and nothing. At this point I remember thinking to myself “I remember taking the one transom strap off, then I had to run up to help them with the boat cover…I must have taken the other strap off too, right??” Well, turns out I didn’t! But throttling it up in reverse did have the fun effect of tugging out 2-3′ of transom strap from the retractable base, which along with my buddy backing me in further (he thought I was just too shallow), left me with a trailer hooked up to the back of my boat, floating about 2′ under me in 4′ of water! Of course trying to pull the trailer far enough forward to get it back on solid ground, along with trying to keep the boat relatively centered on it went about as well as you’d expect. Long story short, I wound up reaching back with a fillet knife and cutting the strap. $50 for the strap was the easy part of the lesson, the hard part was looking like such a dumb@ss in front of my friends!
