Last summer I got hooked and went all gung-ho(had to do something to get profootball and the horrible events of 2/3/08 off my mind). After about a dozen trips or so I bought a 10 ft jon boat off of craigslist from some guy in RI.
Its pretty good for one person but will all my gear, rods, oars, trolling motor and battery in it feels a little unstable. I can stand up in it if conditions are calm, but its not comfy to stand and fish in.
Also the wind really can blow you around in the smaller, lighter boats like this.
Just this morning (4/5) I was out on a new lake looking for smallies, only to realize in the 5 minutes it took me to rig my poles I was blown almost clear across the lake. I spent the next 45 minutes rowing/fighting my way back to the boat lauch. Needless to say I didn't get much fishing done beacuse of the windy conditions.
One thing I can recomend if you want to try a small boat is renting one at the Hopkinton resevoir. I haven't done it so I don't know the rates but I've heard its reasonable. Here is the link and number.
