So you can get the anchor line at one end (prefereably the stern while fishing) of the yak. Anchor tied off to the yak except at the stern (or bow) puts you in a position to get turned over easily. [grin][sad]
Lumps of grass or debris hitting your anchor line, a fish pulling on you, current, or a wave can knock you down fairly easy if not anchored from the end of the boat. [sad]
That's what I thought.I just tie a line from the stern ,then make it long enough so that it is at my side and easy to reach..Tie a loop in the line but don't cut it off yet.Now,pull the loop back again tight off the stern leaving the tag end attached.Sit in the Yak and tie the tag end off next to you where you can just grab the line and pull it towards you to bring the loop back at your side. .I tie mine to my paddle holder.The loop is where you tie your anchor line to.In other words ,if you have a 14 ft.Kayak,you will need about a 14 ft. line if you sit in the center with a loop in the middle with one end tied to the stern and the other tied to your kayak where you can grab it next to your hand at the side of the Yak and pull the loop back to you so you can then pull in your anchor line.You tie the anchor line to the loop,hold on the other side of the loop of the line that's attached to let it slide til the loop with the anchor line is directly behind your yak.I use this method even in the Susky while shad fishing.I just don't see going through the trouble of a trolley when you can accomplish the same thing with a piece of rope.If i didn't explain it well enough,let me know and I'll try to in other words.
If you can tie a rolling hitch it works fine to tie off to a anchor line so it's accessable from the center of a Yak.
For years we did this on big boats that had no good place to haul the anchor from forward.
Another thing we used to do is run the boat up on the anchor line then throw a grapel over it pulling it into the cockpit making it easy for two guys to haul from amidships. It was a big old heavy anchor.
All these rigs have the same end use, But on my yak I use a anchor trolley. It's easy and adjust real quick.
Only thing I do different than most people is I have two. One for forward and another for aft. Less line to run and I almost never need to adjust it the full leingth of the boat.
