"Having landed many tuna in excess of 150 pounds, sails to 50 pounds, white marlin to 100 pounds, blue marlin to 300 pounds, and dolphin to 65 pounds, I DO NOT recommend using a hand line - even if you're wearing leather gloves. Purchase an inexpensive 50 to 80-pound IGFA rod and reel, load the reel with 80-pound mono, then attach a rod holder to one of the aft quarter stanchions. Most skip baits, cedar plugs, etc..., are all effective for tuna when the boat is moving at speeds greater than 5 knots. Swimming plugs are a better bet when the boat is moving slower."
Please clarify; you are saying you've landed all those fish from sailing boats with out stopping, on a pole?
