I'd buy this:
The Superyacht Tiara Yacht PADI Dive Center
Not charter it... buy it...
Then I'd sail it down through the Keys, across the Exumas in the Bahamas, west to Belize, southeast to Roatan, back east to the ABC's (maybe hang in Aruba for a while for an extended SI)... then west across the canal, and a leisurely sail across the Pacific to Fiji, the Solomons, Coral Sea, and up to PNG, and Palau...
Finally, back east to Hawaii... back through the canal to the US Virgin Islands...
... then, buy a bigger boat... because I could...
