I suppose it depends what sort of fish you're trying to catch.. I'm told that sharks aren't fussy but some larger sport-fish think they're very tasty... Trouble is, the line usually breaks and they get away.
Most people use wind or solar which doesn't tend to attract the same attention...
"Honestly, I don't know why seamen persist in getting wrecked in some of the outlandish places they do, when they can do it in a nice place like Fiji." -- John Caldwell, "Desperate Voyage"
