Set up each retrieve before casting. Decide how deep the fly should begin, which feature it should cross and where you will finish the turn. Count it down where necessary, then retrieve with deliberate strips and pauses that keep you connected. A pause can let a buoyant or slowly sinking fly hang beside the cover; too much loose line makes a following take hard to detect.
Watch behind the fly, not only at it. A following muskie may appear as a shadow, a bow wave or a sudden change in the apparent depth of the water. Keep the fly moving as it approaches the boat. The figure-eight demonstrated by Orvis and Fish’n Canada carries the presentation into broad, submerged turns beside the angler.
Make the turns large enough for a long fish to follow comfortably. Change direction smoothly and keep control of loose line. Practise the movement without a fish first, with everyone clear of the rod and hook. You want a repeatable finish, not a frantic flourish when a muskie is suddenly under the gunwale.
When a fish commits, use the line hand to drive the hook while keeping the rod in a position to apply pressure. Once it is securely hooked, clear loose line without trapping fingers or feet. A well-prepared boat lets the angler fight the fish while another person readies the net and tools.
