My understanding is the outer end of the net should be marked with 2 flags, whereas the inner end will have 1 flag. You should be able to run over top of the net, because they should be at least 4 feet below the surface. BE CAREFUL. I inadvertently ran over one last summer off Gem Beach, fouled a prop and had to haul the boat to cut the line off. There was a small float midway between the two flags with the line coming to the surface which I didn't see.
