Just sold my '72 C&C 30 after 11 years of ownership.
Could have kept her another 10 years, but, I was looking for more creature comforts.
Could have spent 10K upgrading, but no amount of reasonable investment would have given me more head, bunk and shower room.
Otherwise I would still have the boat. Great all around sailboat, but a bit too much like camping for a 6'2" person.
I don't have 4, 3, 2, or even 1 footitis, just headroomitis.
I would like to keep my next boat for at least ten years, hopefully fifteen. Then I will be close to retirement and can start looking for a comfy live aboard cruiser.
The hunt continues....
