then I found this:
http://oceancurrents.rsmas.miami.edu/atlantic/gulf-stream_2.html
If he were fairly close inshore when he lost propulsion, etc., he could have drifted south for a while before getting snagged in the Stream.
I still think he looks a bit healthy for having been adrift for 66 days, but at least he had a cabin for shelter. But think of all the fronts and storms that have passed over that area in the past two months!
