Sure it has crossed my mind but cant say I have really given it any deep thought. If I want to go for a fish I hook the boat up and go . When flicking lures I prefer to have the boat to myself, move the electric where I want and dont have to worry about making sure another person does not fall in the drink (anyone who owns a bowmount electric will know what I mean ) or is always lined up for a decent cast and retrieve and if things are slow I can stay or go as I please. I take the bigger boat out the Bar myself and always log on/off with the coast guard and tell the missus where i am going and ETA back. I guess the point of getting knocked out is a good one if there is somebody to keep your head up but when it comes down to it, if the conditions are safe I will always rather go for a fish than miss the opportunity just cause you cant find a decky.
As for launching and retreiving the boat, while the wind can be a pain I think alot comes down to the trailer. A boat 5mts and under and a well set up trailer should be a simple enough job to deal with without turning you off going out. The biggest prob I have is when using the fiberglass cuddy with no sand or jetty to keep the boat off the ramp. Thats my biggest turn off for a solo trip.
