Seems that most if not all Coast Guard inflatables are red like the photo.
On a recent cruise, they DID have high power machinery mounted. All personnel aboard had very heavy duty life jacket gear, and helmets, as they moved around the ship as it exited the harbor. There may have been two.
All part of U.S. Coast Guard presence on our coasts & harbors.

So, instead of the armed Secret Service on foot, and w big black armored SUV, with presidential candidates, we will see armed Coast Guard boats on any body of water!

EDIT: I am now visiting in Annapolis MD. People are on same "creek" as Coast Guard Station is located farther in. We see them go by, in & out all the time. Man here says same red hulled boats made by Zodiac are all over the country. Nothing new for them to be patrolling coast with ships constantly moving; here there are cargo ships constantly moving in/out of Baltimore, for example.

So, to see them around presidential candidates will be nothing new. Same is true if we were to visit an airport where they fly in & out of, we will see additional aircraft on patrol. Even an added plane or two carries the secure automobile the President rides in, and secret service personnel with their vehicles. Nothing is left to chance.

Therefore, THIS is what will happen and what happens NOW on the LAKE!
