Who registers and titles my boat?
Your state, not the federal government. Each state agency publishes its own registration and titling rules, forms and renewals.
Who sets each requirement for a recreational sailboat, and the official page where you read it. This page restates no rule: requirements depend on your state, your boat and the date, so the source is the only safe answer.
Federal and state, both. The US Coast Guard sets the federal minimum for equipment and identification. Your state sets registration, titling and operator education, and may add rules for its waters.

Federal documentation is an alternative to state numbering for eligible vessels, and lenders often ask for it. The Documentation Center sets eligibility and handles applications.
The federal regulation on boat identification sets the format of the hull identification number and where it is marked. Read it off the hull and compare it with your paperwork.
The Coast Guard's federal guide sets the minimum equipment by boat type and length, and your state may add to it. Note which edition you read.
Operator education is set by each state, so the answer depends on where you sail and who is at the helm. Your state agency has the current rule; the Coast Guard lists courses.
An EPIRB or PLB is registered in NOAA's online database, and the owner keeps the entry current when details, ownership or the boat change.
The FCC sets when a ship station needs a licence. The Coast Guard Navigation Center explains how recreational owners obtain an MMSI and keep its details current.
The EPA publishes the discharge rules and the no-discharge zones; marine sanitation devices are certified under Coast Guard rules. Your state may designate further zones.
CBP sets how pleasure boats report their arrival from a foreign port, including its ROAM reporting app and the user fee decal.
Both. Federal rules from the US Coast Guard set the minimum for equipment and identification. Your state sets registration, titling and operator education, and may add equipment rules for its waters.
Because they depend on your state, your boat and the date you read them, and they change. A copied list goes out of date without telling you; the official source does not.
Write each one on the reference page of your record: the authority, the page you read, and the date. Next season you check the source again rather than relying on memory.
