Keeldragger Sailing
Offshore Toolkit

Prepare the boat. Plan the passage. Post it at the nav station.

A readiness checklist, float plan, watch bill, and emergency cards for cruising sailors — bound into one document packet you can print, laminate, and hand to your shore team before you cast off.

One toolkit. Four documents your passage actually needs.

Everything feeds everything else — enter your vessel, crew, and passage once, and it flows into the checklist, the float plan, the watch bill, and the emergency cards.

Offshore Readiness

Know where the boat stands

Self-assess across 26 boat systems and nearly 400 checklist items — rigging to medical kit. A readiness heatmap shows weak systems at a glance, and a stack-ranked priority work list puts the highest-risk open items on top. Attach photos, add your own items, mark what doesn't apply.

Float Plan

The document your shore team holds you to

Vessel description written for search and rescue, crew with photos and critical health information, itinerary with waypoints and distances, comms schedule — and step-by-step instructions for exactly what to do if you're overdue.

Watch Bill

Who's on, when — and what handover means

Rotating watches, the Swedish system, staggered pairs, or a solo rest plan. A visual grid with exact start and stop times, handover tasks for coming on and going off, and a seven-day daily-rounds tick sheet for the walkaround that keeps small problems small.

Emergency Cards

For the moments nobody thinks clearly

Eleven action cards loosely modeled on SOLAS muster conventions — fire, flooding, man overboard, the Mayday script, abandon ship, seacock locations, fuel and electrical isolation. Pre-filled for a cruising sailboat; every line editable for yours. Print, laminate, stow within reach.

Pick your documents. Get one packet.

Tick what you want and the toolkit binds it into a single PDF behind a cover sheet with a contents list — one file to print for the boat, one file to send ashore. A photo-quality control keeps the file small enough to send over a satellite connection.

Built to be used three times

1 · Preparing the boat

Work the checklist over weeks or months. The priority list tells you what matters next; the heatmap tells you when a system is actually ready.

2 · Briefing the crew

Walk the crew through the watch bill, the handover tasks, and every emergency card before departure — the cards are for recall under stress, not for learning on the day.

3 · Underway

The laminated set lives at the nav station: watch times, daily rounds ticked off with a chinagraph, and action cards where they can be reached in the dark.

Your data is your data.

Stored on your devices

Everything lives locally on your iPhone, iPad, and Mac. If you turn on sync, it travels through your own private iCloud account — and nowhere else.

No accounts. No tracking.

No sign-up, no analytics, no third parties. The developer has no server and no access to anything you enter — crew passports and medical details included.

You choose what leaves the boat

Nothing is shared until you export it. Print the packet, save it as a PDF, or send it — to exactly the people you choose.

A planning aid — not a substitute for seamanship. The Keeldragger Sailing Offshore Toolkit helps you prepare, document, and brief. It does not replace training, sound judgment, or experience, and the developer assumes no liability for its use or its output. The captain or master remains solely responsible for the vessel, the crew, and safe passage. Every checklist item, card, and task is a starting point — customize them to your vessel, your crew, and your passage, and verify every location and procedure aboard your own boat.
