We have a TI (way bigger boat), and are divers and snorklers mostly so it's pretty important to have a good anchor. It's mostly sand bottom in the keys and we found the small grappling type anchors that most kayak owners use don't hold well in sand, we even tried two of them for a while. What we ended up with is a 3.5 lb guardian G4 anchor that we picked up at West Marine. I didn't put a chain rode on mine (didn't want to cut my boat up with a heavy chain), plus I have an automatic anchor system with an anchor line spool with 150' of 3/8" line. We also have a small grapple anchor, we park just offshore a lot at sand bars with our powerboat friends and you kind of need two to keep the boat from drifting into other boats, (they get upset, (lol), Without the chain rode you have to have the scope a little longer (like 5/1 or more). Sometimes we are at places a couple weeks at a time, and often just park the boat just offshore anchored every night, (if the resort doesn't have docks or mooring balls).
If I ever do it again I will likely use much smaller rope (like 1/4"), 150 ft of 3/8" rope completely covers the boat piled in a big pile and gets tangled up easily.
When not in use our anchor is suspended over the rudder in the back of the boat, I just use the handy rudder bungy that came with the boat, to keep it from swinging around. We never remove it, it just lives there.

This is our setup, when diving and snorkeling you have to raise and lower the anchor sometimes 10-12 times as the divers move around, and when spear fishing you have about 30 minutes before you have to move on from an area, or your surrounded by sharks, so we use the anchor a lot.
Obviously this setup is not for everyone. You can see the anchor in this pick. The anchor is never removed from the boat, just lives back there, saves a lot of rigging and messing around time.
Just ideas
