Dutchman Bart de Zwart is officially on the list of people I'd like to meet.
Read about his 300 mile journey from one end of the Hawaiian Islands to the other on a standup paddleboard in this Yahoo News piece.
Then take a look at his blog:
"The Ultimate Crossing"
Search the internet and you'll find lots of similar coverage of this great accomplishment.
Bart now lives in Maui, and owns a surf shop in Haiku. The 41-year old did the whole thing unsupported, and is now recovering (and eating) well.
Also check out Bart's surf shop - Kanaha Kai Maui.
I have a feeling he'll be selling more SUP boards and equipment (once he returns to work).
