Here is a list on what not to do when you launch by yourself. These are the steps I performed yesterday. 1. Prep the boat before getting to the ramp, fenders, lines, install plugs, remove back straps, etc. 2. Approach the ramp and back down slowly, once at the slope, switch truck to neutral. 3. Once the boat aft end is floating, put the truck in park and set the parking break. ( I didn't block the tires) 4. Get out of the truck and go to the winch to release the boat 5. Turn the crank to release the latch on the winch that changes the direction of the winch. 6. Slowly crank the boat down. It's 4500 lbs so take your time 7. Lose focus and think your truck is sliding into the water because the boat is moving. 8. Freak out and release the crank so it spins wildly as the boat rapidly goes into the water. 9. Use your elbow and then your wrist to get whacked by the rapidly spinning crank. 10. SWEAR 11. Lick your wounds, and finish the launch. A couple lessons I learned - stay focused, and I should have blocked my tires.
