They are incredibly popular here. I even designed one for the company
that operates two here in Portland.

If you go to Boston on a summer day, you'll see one go by about every five
minutes. Due to their success in the tour business, all the WWII ones
have probably been snatched up and refurbished by now.

I recently read a fascinating book about ocean waves. The author spent a
several years surveying and studying beaches in the Pacific Northwest
using DUWK's in high surf and stated something that I would never have
expected. They are one of the best surf boats ever designed. The drag of
the forward wheels pulls them forward without actually surfing in such a
way that they don't pick up too much speed and risk broaching. Despite
the fact that they will sink if swamped, the author and his crew survived
many years of extensive operation in waves up to twenty feet.

The book is at my office and I'm home but I'll post the title if anyone is
interested. Well worth reading for anyone whose interests in life bring
them into contact with waves. (Would that cover anyone in this group?)
Old and probably unobtainable though.



Anything like the Vietnam era Lark V vehicles they like to use up here for
tours?
