Later, Nilson explained that the technique is very effective on an anchored boat that can't be moved to help the angler. He learned from Jack Webster - a well-known sport and commercial tuna skipper - that the best place to fight a tuna is two-thirds to three-quarters of the way toward the bow, where the rail starts to widen. "Here, a circling tuna can't rub the line on the chine or anchor line," Nilson explained. "If the deckhand has you there, he doesn't want you to move again, so just pry the fish up where you are. When the fish runs, give him line. When he comes in during the circle, wind in low gear. Your crewman will tell you when to lift; he can see the fish better than you. It's a timing thing. At the end, take the rod off the rail and put the butt in your gut, and he's yours."
