Costs are extremely variable. In FL slip
fees for a 40'
boat can range from $250/month to $1250/month.
Maintenance the same answer.
DIY at a low cost yard in N FL might cost you $400-$500 to do a
bottom paint job. Take it to the fancy yard in Palm Beach and pay them to do it will be double or triple or more.
Question is how much can you do and how much do you want to do yourself in
engine maintenance and
repair,
wiring,
plumbing, painting, carpentry, etc. You do it all and live at a
cheap dock then the regular costs could be under $1000/month (not counting
food,
clothing and other standard living expenses, just boat costs). There will be periodic big buck bills that come along. New
sails every 5-10 years $3000-$5000 each.
Engine blows up, new engine $15,000.
So what are your
DIY skills?
