Siliconed my carpeted bunks one fall on the last load of the year just before winterizing. My thinking was it would be easier to move the boat around on the trailer in the garage when I waxed the bottom...which it was. Come spring and first launch, I forgot about it and as usual, I unhooked the winch strap before backing down the ramp. BIG mistake. Kiddos sitting in the back seat didn’t help...got down the ramp half way and noticed in my rear view mirror the boat started to slide off the trailer with quite a bit of concrete left to go. I knew I couldn’t brake, but rather I needed to accelerate to counter the gravity pulling the boat off. By the time I got to waters edge, I was traveling about 10-15 mph backwards. I remember seeing how big the kids eyes were In the mirror as I was backing down the ramp at NASCAR speed. The boat made a huge splash and created a massive stern wave around the dock. Swamped the kids as the boat rocketed off the trailer backwards. Learned a few lessons that day LOL.
