Re: Real Cost
Ok, The OP asked what it really costs didn't he? Well I haven't seen any real numbers, so I'll start with this.
My wife and I live aboard a 39' Catalina in Portland Oregon We have a 40' slip to cover the overall length. We pay $279.00 mo. plus $125.00 for a live aboard fee which covers water,garbage, showers, parking & free ice if you need it. We use a combination of 1 small space heater and a Dickinson propane heater, we cook with propane, we never use the marina shower simply because it's less hastle using our own. Our elect. bill goes from $15.00 in summer to $110.00 in feb. in winter we use about 6-10 gal. of propane per month at $2.79/gal. Other than that, what boat repairs are necessary will depend on your boat and how you use it.
Hope the numbers will help you in making your decisions.
ps. welcome aboard
I'm retired electrician/marine mechanic so I don't usually need any outside help.
