The tactics whiteboard for sailors and coaches.
Build and animate any on-the-water situation, settle it against the rules, and turn it into a protest, a PDF, or a replay you can hand to the jury. Optimist to keelboat, on the grid where one square is one boat length.
Everything you need to explain a situation.
From a thirty-second coaching diagram to a formal protest sheet, SailBoard keeps the geometry honest and the rules where you can see them.
Rule-accurate animation
Scenarios animate to the Racing Rules of Sailing 2025–2028. Boats keep clear, sails flip with the wind, and nothing clips a mark it shouldn’t.
A boat-length grid
Every square is one Optimist length, so the distances stay honest. Zoom, pan, and snap each boat to exactly where it sat.
Protest & defense sheets
Capture the moments, add the facts, and download a clean A4 PDF — six or eight diagrams to a page, ready for the table.
Shareable jury replays
Send a read-only link the committee can simply watch. The animation plays; the editing tools stay out of the way.
AI rules analysis
Ask which rules were broken. The AI umpire reads your diagram and lays out right-of-way, the rules in force, and the likely outcome.
Cases & rules library
Browse animated case studies and rule explainers. Search by case or rule number and watch exactly what happened.
Walk into the room with the whole incident on one page.
A protest is usually two people remembering it differently. SailBoard turns the argument into a picture: rebuild the moment on the grid, animate the approach, and the geometry settles what words can’t. The form does the rest — it asks for the facts a committee actually needs, so nothing gets left out under pressure.

A second opinion before you commit.
Drawn the incident but not sure which rule bites? Ask. The AI umpire reads the boats, the marks and the wind off your diagram and explains who had right of way, which rules were in force at each moment, and where the penalty most likely falls. It’s there to help you think — a sparring partner for the hearing, not the judge. Every read points back to the rule number so you can check it yourself.
Show a ten-year-old the rule, don’t recite it.
The rulebook is dense and the language is for adults. The case library turns it into something a youth squad can watch: search a case or a rule number, press play, and the boats act it out on the same honest grid. Pause at the overlap, ask the group who has to keep clear, then run it on. It’s the fastest way to take a kid from “I think I had right of way” to actually knowing — and it works just as well for a coach brushing up before a regatta.

Your own scenarios, kept in one place.
Drop in the boats, set the wind, place the marks and animate it — a start-line pile-up, a leeward-mark rounding, a tactic you want the squad to drill. Save it to your library and it’s there for the next session instead of redrawn on a whiteboard that gets wiped. Share any scenario with a link: another coach can open it, a sailor can rewatch it at home, and the whole squad can work from the same picture.
- →Build any situation from scratch on the grid
- →Save it to your own library, named and searchable
- →Reopen and edit it any time, on any device you sign in on
- →Share a link so coaches and sailors see the same scenario
Settle it on the board.
