Learn the Rules
by Sailing Them.

You have never raced a boat. Good. SailMOB drops you on a start line and shows you what "starboard" means before anyone yells it at you. The simulator shows you the rule; text only confirms what you already saw.

Sailing School

No download. No credit card. Runs in your browser.

See it before you read it

Wind arrows, right-of-way markers, target-angle cones, laylines. Every rule turns up on screen as a picture first. You will feel who has to keep clear before you can name the rule. Start with the Rules Lab: one encounter at a time, watch the bots play it out, then sail it yourself.

No jargon wall

Windward, leeward, mark-room, VMG. The words show up right when they matter, in plain language, tied to what is happening in front of you. No rulebook homework to get started.

A start line you can redo

Blow the start, foul a boat, miss the mark. Nobody is watching and nothing is at stake. Do it again until the call comes easy. Free, in your browser, no boat required.

Your first race is already waiting.

The fastest way to learn the rules is to sail them, get one wrong, and see why.
