Thank you Trinkka, That bow roller is what I was looking for. I may go with power in addition but only because I'm not worried about my batteries. I've more power than I can use right now and I only really day sail her.
Power is OK. It will save your back from going out and that's for sure. I've had my back go out a couple of times just by standing on the bow trying to hold the strain of the anchor sunk into the mud. Now I just get the line as vertical as I can and just cleat it off until the anchor comes up. The Aluminum anchor is pretty light to handle once the mud is washed off the flukes.
The anchor roller that I'm using is a Bruce anchor roller and it works great. There's no bale on it and I prefer that it doesn't have one because a lot of times when I'm pulling the anchor up the boat floats ahead past the anchor and the angle of the line gets too acute and it becomes hard to pull. I'm usually able to solve that problem by pulling the line up against the bow pulpit rail until the boat gets straight with the anchor. Then I just put the line back on the roller again and finish hoisting the anchor. So what I'm saying is that the anchor roller can be a pain at times in that respect only. Outside of that, you can't beat it.
I do a lot of overnight trips on my boat so I'm always concerned about electric usage but if power consumption isn't a problem for you, I'd say go ahead an buy an electric anchor roller.
Once my anchor is up, my main concern is making sure that all the mud is off the flukes before I have to anchor again. I suppose that there are ways of getting around that problem without having to dunk the anchor back and forth in the water to shake the mud off it though.
With that said though, I really enjoy anchoring and if I have my choice of using someone's mooring for the night or anchoring, I'll always choose to anchor.
