The boat with the person, thats my brother checking the engine pre-flight
The extremely cooling looking USCG boat dry docked, is not a rib. I got to see it up close and personal.

Its aluminum with foam filled pontoons (?), very sweet nonetheless. It has 2 Honda 225s. It was soooo quite while idling, I wasn't even sure it was on.
The huge prop from hell

is quite obviously a dredger of some sort. It came all the way from Florida.
And the picture of the tank " NO SMOKING "!!!! was the last photo my brother snapped off before we were promptly attacked by big brother.
