Sounds like you have it figured out...I'd go there for a few weeks and go and chat to the locals...I'm sure your
marine background will open some doors and you can get some insider info.
You have had your own business before, but I'd still warn you to be weary dealing with banks for this kind of business. They aren't your friend and don't normally care if you go under... but like to sell dreams and as you are well capitalised, they will want to get their hands on your cash. So make sure you have modelled all the caveats into the cash flow model, know your DSCR and have a DSRA.
Also, as your retiring, if you haven't done so I build in exit strategies into your cashflow model so you can change direction based on market conditions or
health etc. You might be better off getting highly leveraged and protecting your capital if there is a feasible structure to achieve that.
My mate did this of the coast of
Africa running
diving. They found it too much
work for the reward and gave up. Selling a
boat when your forced to is not optimal so I'd get down there and try and be the buyer of that kind of
boat.
Best of luck sounds exciting!
