I used to have a trolley system and gave it up. Just one more thing to lug around. Anchors are tricky in wind in a kayak. Don't get a grapple style, things can go bad real quick. There are times I have found fish and wish that I could stay on them, that is where the anchor comes in handy. I just drift around with the wind like an idiot

if you're out there in 20mph winds, you're crazy. small craft warnings. on those days, you're better off going shopping for more gear. the fish ain't worth your life. don't mean to be preaching but I got caught in some surprise high winds. waves were over 1 foot with white caps. wind kept spinning me around and was impossible to keep on even a semi straight course. took waves over the sides when the wind spun me. have not been on that body of water since that day. will not til the weathr settles a bit.
