Fishing Alone

I vote WS Commander 120. 60 pounds, tons of storage space. Easy to stand and fish.

I would recommend an inflatable. They come in all sizes, are relatively inexpensive, and the special "angler" ones have reinforced hulls for those accidental hookups. Most will take an electric motor too.

Should look into a 375 foldcat from SeaEagle.com or a 285 Frameless Pontoon Boat for 1 person
