I just read the post on how some of you load up - power-on or crank-up. I just bought a Mastercraft and I haven't done much loading of powerboats. The lake is fairly calm, no currents with the occasional wake and the launch doesn't get much use so I should have it to myself. Any suggestions anybody could offer to help me out? How do you get it lined up properly? Is it just practice to see how deep to set the trailer? How do you get the boat balanced right?
