I float solo a lot. Fishing solo you're never going to be as effective as fishing with a partner or two, but sometimes if your going to get out its your only option.
I used to just anchor up or get out and fish, skipping the in between water. I also would run an electric and try fishing on the move with that. Works pretty well on larger rivers but can be more trouble than its worth on smaller rivers.
This year I've been playing around with holding my rod between my knees while I row so I can hit more of the in between water. I either run a float down in front of the boat or do the standard side drifting thing.
It can be a bit of a cluster at times and you need to be careful not to get too agressive and not be safe. It can be easy to not pay attention to where your floating if you get hung up, are trying to untangle the ineveible mess, or just trying to hit that really sweet spot and all of sudden be in the trees or worse.
However, it has turned out to be suprisingly effective. I've hit quit a few fish in spots I would have usually passed up fishing solo in the past. Two of the three fish I got yesterday I got holding my rod between my knees and rowing.
Of course once you hook up a whole other set of problems arrises, but that's all part of the fun.
This summarizes my experience fishing alone as well.
