When I had my boat (& yes - the old saying about the two happiest days in a boat owner's life - 1. when he buys it 2. when he sells it - - is 100% true!) Getting it lined up wasn't the issue, having the lights work was always the problem!
Even when I hooked them up on Friday night so I could hit the water early, the stupid things wouldn't work in the morning.
I do not miss that one tiny bit.
