Could be a case of not having done due diligence. If he is wanted for illegal activities related to development schemes, he would have found out the country has already been picked over by shady developers and scam artists. Now on the other hand, if he is a legitimate person sailing the Caribbean on his boat and researched Belize, he would have known that based on the corruption and crime, it would not be wise to let officials know you had considerable cash on your boat.
"How naive does one have to be. Yes, get a credit card, carry travellers cheques, use your atm card, and if he's that fricken rich why can't he arrange to have money wired to him."
Obviously others are naive. Anyone familiar with boats,knows they often are in need of repair, sometimes costly repairs, especially a boat that is capabable of traveling remote parts of the world. Those repairs don't always occur where there is a bank, atm or places that accept credit cards or travelers checks. Last time I was at Glovers atoll, I searched the whole area and could not find one place to have money wired to.
