Holy smokes - fatty! Were you trolling or casting and stripping? congratulations - one of the nicest this year! I fish from a yak too - awesome way to hunt the water.
Tony, it was basically a combo cast/strip/troll for that particular fish. Saw fish jumping; launched the 'yak; got out 30-40 yards and threw a cast; stripped a bit to remove the slack; began to propel the boat forward, stripped again to remove some more slack, and while stripping...bingo. Hooked and landed multiple more fish. Some on the drag, some on cast and strip. Where I happened to be, they were totally keyed on sand lance and small ones 1.5"-2" max. Most casts resulted in either a hook up or the nerve wracking experience of watching 3-4 BIG silvers follow the fly to the yak. As far as dragging the fly behind the yak, I couldn't go more than 2 minutes without a strike. Straight cray.
Way to go! I was up north in my kayak Sunday - casting only....and saw a few nice sized fish jumping - but that one's an extra fatty - no hookups for me.
