The Party Boat Rig gets its name because it is a very common rig that is used on the party boats. It is a simple rig that is easy to set up and it catches fish. Most of the offshore party boats will fish with up to 20 anglers at one time and the boats tend to fish bottom structure. All the anglers have to do is put some bait on the hook and drop it straight down to the bottom. Anglers typically catch snapper, grouper and many other types of bottom fish with the party boat rig.
