As they row back, another line (attached to the net) is fed into the water from the stern of the boat. That line is then attached to a handmade contraption (called a capstan; pictured below) on the bulkhead. A capstan is not necessary but it makes the job of hauling in the net a whole lot easier and a little fun for grandkids.
With both ends of the siene on the beach, they are slowly pulled to shore. If you could see the net underwater it would look something like this diagram (a) . The fish get caught in the net as it is hauled in. Our catch was not much of a success in terms of fish caught. We captured hundreds of jellyfish and 3 smelt - yes 3. But do not fear, Dad has caught up to 700 of this little suckers in one set. And he's had many successful sets. But this day was not our lucky day.
