My buddy's boss has a 160' megayacht with twin MTU 3500 HP diesels.....

...I know, now, why the marina doesn't send out a pump guy to top off our 90
gallon tank on Lionheart unless we bitch at them on Ch 68....

You know that you have really arrived in megayacht world when you no
longer have to go to the fuel dock at all. In major fueling ports like
New Bedford, Mass they will come out to your boat with either a small
or large fuel barge depending on your requirements. We watched a 200+
footer take on 40,000 gallons that way last month. The commercial
fishing boats that operate from New Bedford routinely take on thousands
of gallons at a time from the fuel barges.
