We believe every day’s a school day on a boat! That’s why we built Nautical Know-How, dedicated to answering your questions. Even better, if it can’t answer your question immediately, you can request it, and we’ll add it to our knowledge base.
Nautical Terms & TerminologyUnderstanding the language of the marine world is like trying to learn a pirate’s secret code while juggling fish. Let us explain why a sheet isn’t for your bed, why “heave ho” doesn’t mean throw up (most of the time), and why “dead reckoning” is surprisingly less ominous than it sounds.
Why do we have tides?Have you ever wondered what causes the tides? Check out this video, which introduces the forces that create the tides we experience on Earth.
What causes our weather?A video introducing the drivers behind our weather, part of our RYA Day Skipper & RYA Coastal Skipper / Yachtmaster® Offshore theory courses.

The Salty Sea BlogFrom salty old sea dogs to fresh-faced deckhands, this blog is for anyone who finds peace, adventure, and a bit of mischief on the water. So hoist the main, set your course, and let’s sail into the stories, lessons, and musings that make life on the sea so irresistible.This is the bit that everyone needs to know. It’s divided into three sections and is the only subdivided part of the rule book. Each section focuses on our ability to see one another (or not):
Each section starts with a rule outlining the visibility conditions under which the rules apply.
There is a special provision in the rules for what happens during restricted visibility. Covered in Part B – Steering & sailing rules, Section III is specific to the Conduct of Vessels in Restricted Visibility. There is only one rule in this section, Rule 19. This rule supersedes the other sections of Part B with…
Every vessel which is directed to keep out of the way of another vessel shall, so far as possible, take early and substantial action to keep well clear. Under the rules, a vessel defined as give-way is obliged to ‘take early’ and ‘substantial’ action to avoid a collision. Rule 16 is a summarised, single-sentence version…
Except where Rules 9, 10 and 13 otherwise require: This rule caters to any potential collision between two vessels of different types. In each, one is given the status ‘stand-on’, the other ‘give-way’. The give-way vessel is obliged to take action, but the stand-on vessel has responsibilities too. Hierarchy The underlying principle of the rules…
In an overtaking situation, the usual hierarchy rules fall away, and this rule (13) takes precedence. It specifically refers to the arc created by the 22.5° angle abaft abeam, on either side of the vessel, which co-insides with the stern light coverage required by all vessels in Rule 21: Definitions. Vessels Overtaking
Narrow channels are often found at the entrance to natural harbours and ports. They are usually buoyed, specifically to help commercial shipping navigate in and out safely. We are not prohibited from using the channel, but we must do so without impeding vessels larger than 20 meters in length. Rules for using a narrow channel…
When sailing vessels come together, two potential situations need to be resolved: one in which each vessel is on a different tack (its sails are on different sides) and one in which it is on the same tack (its sails are on the same side). Sailing vessels on different tacks In many cases, sailing vessels…
This rule applies only to power-driven vessels when they come together head-on. Any vessel can be power-driven; for example, a passenger ferry is power-driven in open water. A sailing yacht using an engine is power-driven, and a fishing boat not engaged in fishing is also a power-driven vessel. Power-driven vessels head-on Neither is defined as…
When two power-driven vessels are crossing so as to involve risk of collision, the vessel which has the other on her own starboard side shall keep out of the way and shall, if the circumstances of the case admit, avoid crossing ahead of the other vessel. This rule applies only when two power-driven vessels come…
Rule 17 covers the obligations of the other vessel in the collision situation. Whilst the give-way vessel is expected to alter course and take necessary action to avoid a collision, the stand-on vessel has obligations, too. The primary one is that it ‘shall’ keep her course and speed. It would be unfair for the stand-on…
Rules in this Section apply in any condition of visibility This rule introduces the section and clarifies that everything in Part B—Section I is concerned with what happens irrespective of visibility (i.e., whether vessels can see one another or not).
