We are looking to retire, and move on to a boat in 7~10 years. We had read articles talking about boats in charter having all maintenance, expenses, and the mortgage covered.
I was was assuming these where 10 year mortgages, and we'd be close to having the boat paid off at retirement. But I am guessing now, that is not the case.

Do you need a 30 year mortgage with 20~25% down to have your payments covered? Or maybe a better question, what can you expect as far as cash from the charter company yearly? ~8% of the purchase price?

While I see how ownership time would be a huge plus, if we had the ability to use it. I think we would struggle to use 10 days a year.
