Re: Making a living as a liveaboard
Overall, I would hope you would believe that you will survive / succeed at least as well while living on a boat, as you have while living on land.
As with all of us, as long as you are willing to do what is available to you to earn what you need, you will survive.
I have met some people who place boxes around themselves, wherein they are ONLY a: "realtor / accountant / manager / etc." and it is those people who remain out of work for months & years.
When I have been "in between computer programming contracts", I have taken security guard jobs, washed boats, i.e., whatever was available to me, and therefore never went flat broke.
Good luck and fair winds!
