Lots of factors you didnt list there.
Where are you? In antarctica you wont get any money
because no boats will be there. In Ensenada there will be nobody with any money
(because the monied boats either dont stop there or they just left SD and are fine).
So anyway, lots of variables. I guess it isnt much different from the rest of life. Can you make money at home fixing people's boats?
Not much changes out there, still people, still towns with resources.
I will say though, that it costs money to cruise
, can be done cheaply but I wouldnt count on odd jobs to fund your cruise
. I have run into more than a few deadbeat cruisers who have no money and hope they can earn it along the way. Very few of them were earning a living cruising and not very few were freeloading.
Not saying it cant be done but I can say it seems like "out there" is analogous to "back here" my buddy the sailmaker
makes money "out there" but he was a sailmaker
at home and made money doing it there too.
