I'd be extremely interest in trading my 2520SL for your 2120. However my 2520 would fetch about what you are asking for your 2120, so it would not make sense financially for me, as I want to free up some cash . Check your pm.
I would give the move to a larger hull serious thought. My plans were to sell my 2120 and move up to a 25'. However after long consideration I arrived at the conclusion that owning a larger boat is too much aggravation and adds limitations. The 2120 gives me freedom to trailer up and down the coast. Also, the F150 is extremely economical to maintain and run.
Public ramps with unlimited use cost between 50. and 150. per year. No bottom paint and no slip needed.
I am not on the market for a boat and mine is not for sale. However, I feel compelled to comment on the superb layout of all of your electronics. Outstanding first class job. Your experience really shows. I have a feeling that Seneca Lake Dave will be contacting you soon. Charge him extra due to all his whining.
