Maritime Master Whiteboard

Maritime Master Whiteboard is the sketching tool the classroom and the clubhouse have been missing. Draw pilotage plans, chartwork exercises, mooring briefs, and race tactics over real chart backdrops, then share the result in seconds.

​

Instructors reach for it to explain a tidal gate, race officers use it to brief the fleet, and students use it to sketch their way to understanding. If you have ever drawn a harbour on the back of a napkin, this is the upgrade.

​

Start From a Real Backdrop

Capture a chart-style snapshot of anywhere in the world, with seamark detail overlaid on the base map, and sketch straight over the top. Prefer a clean slate? Start from a blank open-water canvas instead.

​

A Proper Maritime Symbol Library

Drop in more than forty draggable, resizable, rotatable symbols across seven categories: cardinal marks, lateral marks for Region A, preferred channel marks, hazard and safe water marks, racing buoys, vessels large and small, and wind and tide indicators. Everything snaps together into a clear, teachable diagram.

​

Natural Drawing Tools

Sketch with Apple Pencil or a fingertip using pens, markers, and highlighters, erase and lasso to tidy up, and keep bearings straight with the ruler. Three modes keep things simple: edit to draw and place symbols, pan and zoom to move around, and a locked presentation mode for teaching from the screen.

​

Save, Export, Share

Projects save on your device with full editing whenever you come back, and any board exports as a crisp image through the standard share sheet, perfect for AirDrop to the fleet, course handouts, or the club group chat.

​

Private by Default

No accounts, no analytics, no cloud lock-in. Your boards live on your device and go only where you send them.

​

Who It Is For

Made for sailing instructors and coaches, maritime lecturers, race officers, cadets, and students. Sketches are teaching aids, not navigational charts, and must never be used for real-world navigation or passage planning.

​

Part of the Maritime Master Family

Teach the theory alongside it with Maritime Master IALA Buoyage for the marks, Maritime Master COLREGs for the rules, and Maritime Master Skipper for the chartwork behind the sketch.

​

Frequently Asked Questions

Do I need an account or subscription? No. Whiteboard is a one-time purchase with no sign-up, and your boards are stored locally on your device.

​

Can I use my own chart area? Yes. Navigate the built-in map to any location and capture it as your backdrop, complete with seamark detail.

​

Are the exported diagrams real charts? No. Exports are teaching sketches for briefings and study, never a substitute for official charts and publications.
