The only reg out there is this:
IN NON-TIDAL WATERS OF THE STATE IT IS UNLAWFUL:
1. To use more than three (3) rods at one time (except for ice fishing) or more than two (2) hooks per line.
That's only for non-tidal areas (i.e., freshwater). No limits on tidal areas that I could find.
If you're using it in a tidal area, it doesn't matter. If you're using it in a non-tidal area, it's a no-no. These are Maryland regs though. You don't fish in Maryland much though do you?How does a king rig fall into play? I bought one a while back for live lining and it has three hooks on it.
