It was hoped that the main beneficiaries of the new harbour would be those employed by the local pilchard, crab, lobster and crawfish fishery. However, there was also an intention to form a "Mullyon Trading Company" based at Mullion, a commercial organisation to help local farmers, retailers and other occupants of the southern part of the Lizard Peninsula who had otherwise to travel on very poor roads to the Ports at Gweek and Porthleven. In doing so they could continue to supply ships anchoring in the Mullion Roads when delayed by bad weather or easterly winds. It also allowed for raw materials such as cement, wood and coal to be delivered.
