Sail Commons

Most sailing knowledge gets handed over in person. Someone who knows stands next to someone who doesn't, on a boat, and explains why the boat is doing what it's doing. It's a good system. It's also a closed one, because it depends on already knowing a person with a boat.

Sail Commons is an attempt to open it up. It's an open source approach to sailing knowledge, built for young people who want to get genuinely good at this and who don't have a family mooring or a club membership to start from.

What open source means here

The same thing it means in software. The material is free to read and free to reuse, under an open licence, so a sailing school on the other side of the world can take a lesson, translate it, adapt it to their water, and publish it without asking anyone's permission. When something is wrong, anyone can say so in public and the record gets corrected.

No membership wall, and no sign-up before you're allowed to read something. If a fifteen-year-old with a library card and a borrowed dinghy can't use it, it has failed.

Who this is for

Young people learning to sail, and the people teaching them. A club instructor putting a season together. A parent trying to follow what their kid is being taught. Someone in their twenties who crewed once, loved it, and wants to actually understand the boat instead of just following instructions.

Experienced sailors are welcome here, and their corrections are a large part of how this is meant to work, but they aren't who it's built for.

What I want this to be in a year

A body of sailing material that anyone can teach from. Plain explanations of how a boat actually works, what the rules mean before you have to know them by number, and how to read the water you're on. Written to be understood the first time, and correctable by anyone who knows better.

Where it is today

Nothing but this page. I registered the domain in July 2026 and I'm building this over the following year, in the open. I'd rather say that plainly than dress an empty site up as a launch.

If you teach young sailors, or you learned this way yourself and still remember what was missing, I'd like to hear from you.
