Is a 30 footer too small? For what? for how many? What is your expectations ? what are you willing to give up? what do you hope to gain?
Not a simple question.
As far as I am concerned a 30 footer is not too small .I lived on a 27 footer for 2 years with my husband and a small dog spending that time in the Keys and the Bahamas and mainly at anchor and with no shower and no refridgeration and very little money.We have no horror stories to tell and had a great deal of fun.
What do you want?
