Loading her on the trailer 3 22 12 012 OK. So she's raised up high over the trailer and ready to be lowered. Believe it or not, this can be the most dangerous step if you're not careful. Caution: Make sure that the trailer is centered and most important of all, make sure that the trailer is level from side to side. Shore up under the wheels if you have to. Put a carpenter's level on the trailer and make sure that it's not leaning. If the trailer is leaning while you're lowering the boat, the boat's hull could hit one of the bunks and upset the boat right off the stands. The trailer isn't going to move but the the stands will tip, and so will your boat. So keep this in mind. Just make sure that the boat clears everything and the keel finally comes to rest right square in the center of the trailer's keel board. If the trailer is off a little with the keel, just use the speedy jack trick under the trailer. If the boat is too far forward, just move the trailer ahead a little so that the bow comes to rest in roller on the winch stanchion. Just keep the boat level as she descends on to the trailer.
