i probably need to explain a bit further...yes bill, while in the water and you touch the metal ladder is when the sensation is felt. the docks are composed of wood planking over metal framework which sets on encapulated foam floats. then from each of the shore side corners are steel cables attached to a land based metal supports driven or cemented into the ground. some of the docks that have this problem have pumps mounted on them. (not submersible)ususlly 120v for washing boats or cleaning fish. also neighboring docks are at least 50' away.
one thing i did learn was the local power co. has lines running across the lake at various locations???? thanks for the comments, ken m
