I STRONGLY urge you to rethink the way you are rigging your anchor. Please look around how others are doing it so that it can be quick released in case of emergency. The way you have it, you're fastest option to get off anchor would be to cut the line. That is not a good thing if you find yourself in an emergency situation.
The anchor line should be looped through the ring on the trolly, not passed through directly. It should come to a quick release cleat so that all you need to do to come off anchor is release the cleat and the line slips through the ring on the anchor line. It is also advisable to put a float of some sort on the bitter end of your anchor line. This way, you can release the line, get awry from it safely and come back to pick it up later.
It is a nice job you have done installing the trolly system. Very wise to have one. Not sure where you fish, but on the coast wind and current can make situations where you need to be off anchor quickly (or needing to dodge crazy boaters). Not to mention hooking up a really big fish and taking a ride. Folks around these parts hook bull reds all the time. It's a lot easier to land one of these monsters if you're boat actually becomes part of the "drag" system. The only way to make that happen is get off the anchor line and let the fish pull you. Besides... it's fun.
Here's a very basic video that explains the concept I mention;http://www.youtube.com/watch?v=WglOaACZe1E
PLEASE take a moment and understand this concept. It is VERY important to understand this. Also, ALWAYS keep a sharp knife on your person at all times when you have this much line running around your boat. You don't want to be looking for one when a bad situation occurs. A small dive knife attached to your PFD (which you are wearing at all times, right?) is a very good idea.
Kayak fishing is meant to be fun. Think about these things in the comfort of your garage, so you don't have to when you're out on the water.
Have fun, be safe.
