Our lake is down 15 ft, the ramps are useless, and the crane had to be set-up in a certain area. When we lifted the 1st boat, it became clear the boom on the crane would not be able to raise high enough to go in front of the tree and right over the ramp, so we had to go over the trees.
47 boats in and out, no scares or incidences, took 7 hrs to put them in, 5 hrs to take them out.
