Me personally, a king of about 25 lbs. at Pt. Defiance.
While guiding in Ak. where the king limit is 1 per day for non-res. I had 4 guests on board, 3 kings (biggest being 32lbs.) in the box and we tripled up, 1 came unpinned but we got the other 2 to the boat, they were twins in the mid 40's, we chose the one that looked the biggest and unhooked the other the one we kept was 46 lbs.
I've also released a bunch of big halibut, voluntarily.
