The Seine Boats were heavy oak craft long. They weighed up to 30 tons, and were rowed by six crewmen. In addition the crew included two Net Shooters and a bowman. The boats were directed to the pilchard shoals by the Huer and enclosed by circling them with the nets. At Mullion each boat had an "area of ground" whereby the crew had to cast their nets and complete the enclosure of the shoal or part of the shoal as they drifted. These areas or "Stems" as they were called were marked out on land by large posts in the ground on the cliffside and there was a responsibility to complete the enclosure between the two designated markers before retiring and allowing the next boat to come in and cast their net. This was to prevent arguments. The Net Shooters had the extra responsibility of paying out the nets in an accurate manner without tangling and at the direction of the Master Seiner. The bowman provided additional assistance. A second boat, called the "Volyer" or "Follower", carried the "Tuck Net" which was used to remove the fish from the seine net. The "Tuck Net" was the equivalent of a large bag net which made it possible to transfer smaller quantities of fish at a time from the Seine Net to waiting boats before transfer ashore. A smaller boat, called the "Lurker" or "Cock Boat", contained the Master Seiner. The fine mesh Seine Nets, cleaned or barked after each use weighed up to 3 tons each and could be 1200 feet (360 m) long and 60–70 feet (about 20 metres) deep. They were then brought ashore, where they were "baulked" with salt in fish cellars and later casked and transported abroad by the merchants across the Mounts Bay.
