Ask how fast a boat is going and a sailor will answer in knots<\/strong> – not km\/h or mph. If you've ever wondered what \"we're doing 6 knots\" actually means, here's the simple answer: 1 knot = 1.852 km\/h<\/strong> (about 1.15 mph). Below you'll find an easy conversion table, a quick way to estimate it in your head, and why sailors stubbornly stick to knots.<\/p>\n\n\n\n

What is a knot?<\/h2>\n\n\n\n

A knot is one nautical mile per hour<\/strong>. And a nautical mile isn't arbitrary: it equals one minute of latitude – 1\/60th of a degree – which is why it's so useful at sea. One nautical mile is 1.852 kilometres<\/strong>, so one knot is 1.852 km\/h. The word itself comes from the old practice of counting knots in a rope streamed behind the ship to measure its speed.<\/p>\n\n\n\n

The quick mental trick<\/h2>\n\n\n\n

For a fast estimate, double the knots and add about 10 %<\/strong> to get km\/h. So 6 knots → 12, plus a bit → roughly 11 km\/h. Close enough for everyday use. For mph, knots and mph are almost the same – just add roughly 15 %.<\/p>\n\n\n\n

How fast does a sailing yacht actually go?<\/h2>\n\n\n\n

Cruising yachts are not fast by car standards – and that's the whole point. A typical monohull sails at 5 to 8 knots<\/strong> (roughly 9–15 km\/h); a performance catamaran can hit double figures in a good breeze. Wind strength drives it all, which is why sailors read the Beaufort scale<\/a> so closely: more wind (up to a point) means more speed. At a gentle 6 knots you cover a lot of coastline in a day while still having time to swim and explore.<\/p>\n\n\n\n

Why do sailors use knots?<\/h2>\n\n\n\n

Because it makes navigation elegant: since one nautical mile is one minute of latitude, speed in knots ties directly to the chart. Aviation uses knots for the same reason. It's a global standard at sea, so wherever you sail, \"knots\" means the same thing. Curious about more sailing basics? Our sailing wiki<\/a> has you covered.<\/p>\n\n\n\n

Frequently asked questions<\/h2>\n\n\n\n

How many km\/h is 1 knot?<\/h3>\n\n\n

Exactly 1.852 km\/h, which is about 1.15 mph. It comes from one nautical mile (1.852 km) per hour.<\/p>\n\n\n\n

How fast is 10 knots in km\/h?<\/h3>\n\n\n

10 knots is 18.5 km\/h (about 11.5 mph) – a brisk pace for a cruising yacht.<\/p>\n\n\n\n

Why is speed at sea measured in knots?<\/h3>\n\n\n

Because one nautical mile equals one minute of latitude, so speed in knots links directly to the navigation chart. It's the international standard at sea and in the air.<\/p>\n\n\n\n

Conclusion<\/h2>\n\n\n

One knot is 1.852 km\/h – and once you know that, \"we're doing 6 knots\" makes perfect sense. It's a gentle, wind-driven pace that's all about the journey. Ready to feel it? Discover our sailing trips<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
