Dignity D 727 is Potting catamaran operating out of Dun Laoghaire harbour.

A potting boat is a fishing boat that is specifically designed to catch lobsters and crabs using pots or traps. Pots are typically made of a metal frame covered with mesh and have one or more funnel-shaped openings that allow the lobsters or crabs to enter but not escape. Pots are baited with fish or other seafood and then lowered to the seabed using ropes and buoys.

Potting boats are typically small and manoeuvrable, making them ideal for fishing in sheltered waters and around rocky reefs. They are also typically equipped with a pot hauler, which is a machine that helps to haul the pots up from the seabed.

Potting is a sustainable fishing method, as it does not damage the seabed and only catches lobsters and crabs that are large enough to enter the pots. Potting boats are an important part of the fishing industry in many parts of the world, including Ireland, the United Kingdom, and the United States.

Catamarans' parallel hulls create reliable form stability, which prevents heeling and capsizing, and greatly reduces the vessel roll at rest and at trolling speeds. One of the most obvious advantages of catamaran stability is in the elimination of seasickness for passengers.
