If a sailing boat is on passage in international waters near US territory, can it anchor overnight within territorial waters for eg shelter/rest/repairs or whatever if nobody goes ashore?


I believe the issue is not about whether people ("persons") on the vessel have visas or not. Whether or not they have visas is completely irrelevant to anything except when going through customs to see if they'll let you in. All cargo, the vessel itself, and people on board, even if they have US passports, must check in to customs.

Vessels that have not cleared customs usually follow strict rules. It varies by country. Vessels are allowed to pass through seas belonging to another country to reduce their travel distance, or wait in a harbor if required. When entering foreign waters, and before clearing customs, the vessel usually flies the yellow and black quarantine flag. It should proceed directly to a port of entry to clear customs, where only the captain will go on shore. If you have passengers who cannot clear customs, then your whole boat will probably be restricted and those passengers will not be permitted to go on land (unless you hand them over to customs as stowaways). After checking in, you should still be able load and unload other people and cargo and buy supplies even if your boat doesn't clear. Customs should tell you what you're allowed to do.

So your question is about if a boat that has not cleared customs can anchor in a foreign country's waters. Well the answer depends on the country. For the US the answer is no except for emergencies or as needed to check in.

For the USA, disregarding emergencies:

Until you have cleared customs, it is not legal to anchor, tie up to a dock or tie to a buoy unless you are there to check in. Other then docking assistance, only the vessel captain may leave the vessel until check-in is completed.

Law depends on circumstances. OP specifies yacht and "sailing boat" & "overnight". Under those circumstances this is common practice and is part of "innocent passage".

A sailing craft anchoring overnight 10 miles off the coast is not the same as a guided missle cruiser sailing into Boston Bay without permission.

Even pulling into a confined harbor without everyone having visas wouldn't necessarily land you in hot water. Allowances are made for circumstances. The laws & customs of the sea place a very high priority of safety, and by and large, they are pretty much common sense.

Are you subject to U.S. law within U.S. territorial waters? Sure, BY DEFINITION, because that is what "territorial waters" MEANS. Does everybody on board have to have a visa or equivalent to anchor overnight. Absolutely not.

Of the above, I'm certain. I'll go further, but without certainty. Even on cruise ships coming into port, I don't think people who don't leave the ship are legally required to have a visa. Also foreign Naval vessels on state visits (or for emergencies) - I'm fairly confident the same applies.

    This sounds very plausible but only the most naive/trusting person would sail their boat into U.S. waters without visas, just because some anonymous person on the Internet said it would be ok. – David Richerby Apr 21 '18 at 19:31

    Cruise lines usually require you have the ability to enter the countries where they port. You can't usually just say "oh I don't have a visa but I won't get off the ship." You'd have to check with the cruise line for their specific policies at each port if you really wanted to rely on this. Otherwise, the risk of being denied boarding and missing the whole cruise is too great. – Zach Lipton Apr 21 '18 at 21:05

Once the craft enters US territorial waters, for any reason, US Customs and Border Protection must be notified immediately and the vessel is subject to inspection, along with all aboard. Both it and its passengers have to comply with US laws, including immigration, and those who require prior approval before travel to the United States (ESTA, visa) must have done so.

Pleasure Boat Reporting Requirements

Pursuant to 19 CFR 4.2, operators of small pleasure vessels, arriving in the United States from a foreign port or place to include any vessel which has visited a hovering vessel or received merchandise outside the territorial sea, are required to report their arrival to CBP immediately (see 19 U.S.C. 1433).

The master of the vessel reports their arrival at the nearest Customs facility or such other place as the Secretary may prescribe by regulations. These reports are tracked in the Pleasure Boat Reporting System. Pursuant to 8 CFR 235.1, an application to lawfully enter the United States must be made in person to a CBP officer at a U.S. port-of-entry when the port is open for inspection.

Reporting Requirements

CBP has designated specific reporting locations within the Field Offices that are staffed during boating season for pleasure boats to report their arrival and be inspected by CBP. The master of the boat must report to CBP telephonically and be directed to the nearest Port of Entry to satisfy the face-to-face requirement, or report to the nearest designated reporting location along with the boat's passengers for inspection.

Exceptions to Face-to-Face reporting to CBP

Alternative Inspection Systems (AIS) satisfy the boat operator's legal requirement to report for face-to-face inspection in accordance with 8 CFR 235.1, but boaters must still phone in their arrival to satisfy 19 USC 1433.

There are four exceptions to the face-to-face inspection at a designated reporting location, NEXUS, Canadian Border Boat Landing Permit (I-68), Outlying Area Reporting Stations (OARS), and the Small Vessel Reporting System (SVRS). Participation in any of the programs does not preclude the requirement for physical report upon request by U.S. Customs and Border Protection.

Any small pleasure vessel leaving a United States port into international or foreign waters, without a call at a foreign port, does not satisfy the foreign departure requirement. Therefore, certain fishing vessels, cruises to nowhere, or any vessel that leaves from a United States port and returns without calling a foreign port or place, has not departed the United States

    This answer is incorrect, because the CBP page it quotes is imprecise. The web page says "vessels arriving in the United States", but the regulation actually concerns "arrival in any port or place within the U.S." (emphasis added), so it does not apply to vessels in territorial waters. Furthermore, at 19 CFR 4.0, "arrival of a vessel" is defined as " that time when the vessel first comes to rest, whether at anchor or at a dock, in any harbor within the Customs territory of the U.S." – phoog Apr 20 '18 at 19:02

    I disagree. The question asks about 'shelter/rest/repairs' which strongly suggests a port of some sort. – xyious Apr 20 '18 at 20:55

    @xyious It implies it, but it doesn't outright say it - a good answer would simply say that out at sea within territorial limits, you're good without visas; come into port, you need visas. – Jim MacKenzie Apr 20 '18 at 22:50

    Worth noting that your vessel occupants probably won't meet the conditions for the VWP (unless the operator is a signatory carrier), in which case the reference to an ESTA is incorrect. If visas are required, they will be required of VWP travellers as well. – Hedgehog Apr 21 '18 at 10:24

I have been on cruise ships who specifically will dock somewhere but certain people are not allowed off due to visa. So, therefore, yes, a ship can anchor without a visa.

    A cruise and a yacht are two different things. – JonathanReez Apr 21 '18 at 18:31

    Out of curiosity, was it docked at a US Customs Port of Entry? – Alex Cannon Apr 21 '18 at 22:19
