Liveaboard Houseboat Cost?

wow that's alot of questions,but i'll try to hit the high spots. i've lived on my 34' sport fish/express cruiser for 4 years with my girl friend and may not ever live in a house again, if that gives you any idea about the life style. it will be difficult for me to give you exact prices in your area, as i live on the gulf coast in alabama. fuel economy on boats is generally measured in gallons per hour. don't expect much more than 1 mile per gallon.also marina fuel is higher , even tho there is no road tax involved. i bring my fuel in, in 55 gal drums, but if your marina sells fuel(mine doesn't) don't expect them to be that nice. slip rent for liveaboards here averages about $10.00 per foot. i was lucky enough to find a nice marina that charges a flat fee of $250.00 per month. had to fight with the power company to get a residential rate, as they want to charge commercial rate for boats for some reason.power will be higher,boats aren't insulated that well. i have an 8,000 btu a/c with a 3,500 watt heater. a reverse cycle cruise air is more efficient. i pay up to $200.00 a month in the winter. there is NEVER enough space for all of your stuff. it may be difficult if you are a material person. if you aren't going to use something every month, you don't need it. i bought a storage building to keep some things in, but it's a pain at best. then there's haul out costs. you will need to haul the boat every few years to check/repaint the bottom and running gear.barnacles are not nice and will kill your speed/fuel economy. as far as pricing? i did a repower on an older 47' not long ago that cost $30,000.00 for the engines installed alone. a marine surveyor is worth his weight in gold to avoid getting ripped off. hope this helps. feel free to contact me through yahoo if you think i can help. good luck!
