Thanks for all of the replies. I am seriously thinking about trading the boat on a 21 foot lowe with a 115 on it so motivation should not be a problem but I do wonder how hard it will be to hold it over a brush pile in the wind.
I will have a 80 lb Terrova with IPilot on the front so hopefully that will hold me fairly steady over the brush. The 55 lb Power Drive I have now has IPilot and I love it. It works a little harder on windy days but I still stay fairly close to where I want to be once I learned to set the spot lock upwind of where I want to be!

I do wonder what type of anchor I will need to hold a pontoon still when I decide to anchor. I dont have much luck getting anchors to bite even with my small boat (yes I let out a 5 to 1 line to depth ratio) so I can only imagine the cussing that will go on trying to get a pontoon anchored up!
What type of anchors work best for you when trying to get them to bite and hold?
