It sounds as though you have already made up your mind. Living and cruising on a boat can be an awesome way of life if you are in love with the lifestyle, but people change and what was heaven for you ten years ago may not be so now. It will not get better once your project
boat is finished and to miss your 'window' for finding love and happiness might leave you resentful of the sacrifices you make for the dreams of yesteryear.
I am assuming you are only joking about living in a shipping
container, but maybe selling the boat and doing a bit of world travel - Asia
, inland areas or driving the West coast
in a Mustang ... whatever floats your boat (oops ... too soon?).
Look at your priorities, find your partner (having neither looks nor money
myself, I would be cashing THAT cheque if I were you) and if she is boaty, then find something to sail together.
Just don't forget that pre-nup.
Best of luck!!
