These days my flyfishing is limited mainly to lakes in and around the Sierras. Most of the time I either cast from the shore or wade in. Lately, I have been wanting to venture out and have rented from time to time small boats (10' with 5hp motor). I would like to buy some type of watercraft to have handy. What would you suggest for use in lakes that could be considered small to medium in size and winds not exceeding 20 - 30 miles an hour (rare)? I am not necessarily looking for a boat. I need something I can carry or launch on my own.
