Thresher Sharks are the jewel in the crown so far as shark angling goes. For those wanting to complete the UK shark Gand Slam, they probably rate on a par with the Mako Shark. Least ways they did until recent times when the grounds to the east of the Isle of Wight started producing them reasonably regularly. Still a rarity though, and a species Andy Griffith required to complete his Grand Slam. But instead of being fortunate enough to catch one, here he describes three days fishing which produced the staggering total of five.
