Do you love big bluegill?
You don't even need all of that. Just get a couple good-sized carabiners, some parachute cord, and a metal ring (I actually use a metal triangle). Clip one to the carry handle on the bow, the other to handle on the stern. Tie one end of the para-cord to the ring. Run the cord through the bow clip, along the side to the stern clip, then back up the SAME side to the ring. Tie the cord off, making sure to get as much slack as possible out of the loop, while keeping the loop on the side of the boat, and not cutting over the cockpit.
a anchor type I use to use was called a -- doll mate. once attached to your boat- swivel the pully - up- then run your rope thru it- tie on your anchor. all of the other rope is close to you. to let it down; just pull back on the rope; swivel pulley will go up;; easily let the rope down to your desired depth. let go of the rope! swivel will go down automatically locking it in! to pull it up-- just start pulling the rope!
I'm not a fan of trolly systems for my style of kayak fishing. I'm in a river, with current. Allot of it. You drop an anchor towards the stern of your boat or off the side, you have a possibility of turtling the yak (flipping it), loosing gear, and worse.
Although I do have an anchor on my yak - off the bow of the boat so I can see it when I drop it. Carabiner in the carry handle, and a jam cleat is all I have. Simple.
Always carry a knife handy - something you can grab & cut the rope in a hurry if you get into problems. I have a River Gerber on my life vest at all times.
