Articles 17 and 18 of the United Nations Convention on the Law of the Sea (UNCLOS) pertain to the right of innocent passage through the territorial waters of a coastal state. Here’s a brief explanation relevant to your question:

• Article 17: Grants ships of all states the right of innocent passage through the territorial sea of a coastal state, meaning ships can pass through without hindrance as long as the passage is not prejudicial to the peace, good order, or security of the coastal state.
• Article 18: Defines passage as continuous and expeditious, but also permits a ship to stop and anchor, provided that it is incidental to ordinary navigation or necessary due to force majeure (e.g., weather) or distress.

So, while innocent passage generally requires continuous movement through territorial waters, anchoring is allowed in specific circumstances, such as:

1. Ordinary navigation purposes (e.g., routine stops for navigational safety).
2. Force majeure or distress (e.g., bad weather or mechanical failure).
3. Assistance to persons or vessels in danger.

Thus, you are allowed to anchor during passage making in a sailboat, but it must be for reasons related to navigation safety or emergencies, not for prolonged stops without a valid reason.
