We usually just used a big plastic handreel with about 100 ft of
cheap green
rope about 6mm like used on crab pots, a good quility Black
game fishing swivel with ball bearings cost abot $6-00 each but worth it if using a lot, then about 6 ft of piano wire. attached to a cheaper 60kg swivel we'd have a large torpedo sinker on this wire and then another 6ft of piano wire another 60kg swivel followed by a nice shiny Halco Barra spoon. Try to use Black coloured swivels as the fish will go after shiny ones.
The important part was attaching it to the
boat. We used old bicycle inner tubes [ free at bike shop] fed through the reel and back through itself, and then back to and through a horn cleat. This takes the shock out of your
gear and let's most fish have a run without breaking off. We never had a tube break and man , can they stretch when you get a good un' on the end.
We always had this out as soon as we started to sail and in some places had a fish on before you'd get to the end of the line. We were rarely without a feed while cruising.
When a fish jumped on we'd just tow him aroun for a while until they were worn out and then they were quite easy to deal with.
