There are three different "areas" where the Navy deals with "small boats".
First, you have the units that are protecting harbors.
Second, you have the new Riverine Squadrons. .
Finally, there are the Naval Special Warfare boats.
You are missing quite a few "areas" that deal with boats.
The largest area is the Amphibious Navy. In addition to the landing craft like LCVP (Higgins Boats) Mike 6, Mike 8, and LCUs, the Navy uses command and control boats, as well as salvage craft (including amphibious wheeled boats called LARCs)
The next area is salvage. Navy divers have a large assortment of boats that they use.
Then there is the Amphibious Construction battalions (Called PhibCBs) who use modified Landing craft as "pusher" boats and tugs to control causways and barges. and assist in building and salvage ops.
Of course, every ship has a "Motor Whale Boat" at the ready in case of a man overboard. These boats are mounted so they can be quickly lowered with a crew and rescue personel if needed. During Flight Ops, or other hazardous ops (like refueling at sea, or underway repleneshment) these boats are usually staffed and ready to drop into the water in just moments.
Most ships also have a Captains GIG (fancy boat) , which is used to transport the captain, or others from ship to ship, or ship to shore. In addition, larger vessels may also have an Admirals Barge (bigger fancy boat).
There are a lot of TUG BOATS in the Navy. While generally not regarded as "small boats" they are classed as boats, and not ships.
The other area is in Security. While stationed overseas, or in combat areas, at anchor, the Navy will deploy Security patrol boats that keep other boats or enemy divers away from the Navy ships. These boats could be the ships own (like a Gig or motor whale boat) loaded with some sailors and hand weapons, or could be more specialized boats like a RIB or Fast Craft and mounted weapons.
