Can't find the short

Well, we spent several hours tracing wires and were just unable to find the short. We can't even figure out if it's on the stern light or the bow light Soooo... we're going to hire an electrician AGAIN. This time, the problem is easily reproducible, so hopefully the electrician will be helpful. We're going to stay overnight here ($3.05/foot plus $25 for electric + $18 for water) and the electrician gets here at around 8am. We're looking to get out of here by 11am or so and continue on our way to Charleston!
