 Doggers were slow but sturdy, capable of fishing in the rough conditions of the North Sea.Like the herring buss, they were wide-beamed and bluff-bowed, but considerably smaller, about 15 metres long, a maximum beam of 4.5 metres, a draught of 1.5 metres, and displacing about 13 tonnes.They could carry a tonne of bait, three tonnes of salt, half a tonne each of food and firewood for the crew, and return with six tonnes of fish.
