Lucky guy...I grew up rowing a 6 foot pram aroung the bays of Whidby Island and caught many many salmon that way. I used to use a Canadian Wonder and 2 oz kidney sinker and go like crazy, then pause and let the spoon sink, then go like crazy until the spoon was near the surface again. Was deadly and fun. The fish would slam it as I began rowing hard, so the hook set wasn't too much of a problem.

Another suggestion for jigging that you may not have considered is casting as far away from the boat as is possible and freespooling to the bottom. Then pull hard a full sweep and reel in the slack, repeat three or four times and freespool to the bottom again. Do this all the way back to the boat.

Blackmouth are full of energy and will work much harder to get food than a lazy ol' King. The quick is the deadly. Good Luck and damn that brings back some fun times!
