[Scan-DC] Potomac Harbor Units

[Rick Charles]

At about 4:20 PM this afternoon I was crossing the Potomac on board a 
VRE commuter train and observed a police vessel under the 14th street 
bridge near the Pentagon side of the river.  The boat was moving slowly 
as if conducting an inspection.  The boat was a "go-fast", about 15' in 
length with twin outboard engines and had a single officer at the helm. 
There was no pilot house of any kind.  The officer was wearing a light 
blue polo shirt with only the word "POLICE" on his back.  No other 
markings were observed.

Question for the group:  What units, if any, other than MPD actively 
patrol the Potomac in the DC vicinity?  Does Bureau of Customs and 
Border Protection (BCBP-former Customs), Park Police, or any other 
federal agency have a maritime security mission up here?

And, what are the operating channels/frequencies.

Also observed a USCG buoy tender heading north bound on the river 
adjacent to Quantico MCAF this morning but couldn't see him this afternoon.

Thanks.
