You can buy rig maps that show all the blocks and rigs within the block by name/number. I have not relied upon one in many years so I can not attest to the currency of the information as rigs are being removed from service quite regularly. GPS mapping software will also have the same information but the frequency of updates may influence accuracy. If you are in a small boat (bay boat) you can catch all of the above mentioned species and never lose sight of land.....so a map is not needed but a compass/gps is recommended as you don't want to get caught out in fog in the early spring or fall.
