Rainbow's End Manifest

The book of your boat

$9.99 · Designed for iPad. Not verified for macOS.

The Coast Guard’s safety list, built from your boat and cited to the rule; where it’s stowed; the guest briefing; the log; the upkeep. One purchase, no account. The Coast Guard’s equipment list, derived from your boat and cited to the regulation. Where each item is stowed, the briefing your guests hear, her log, and the schedule that keeps her fit: one book. Enter your vessel once — length, propulsion, fuel, heads, tanks, systems — and every page derives from her. Change the boat and the book redraws. GEAR — The federal safety-equipment checklist for your boat’s size and waters, with the 33 CFR and 46 CFR citation under every item: wearable and throwable personal flotation devices (PFDs), 5-B and 20-B extinguisher ratings, visual distress signals and their expiration rules, sound signals, navigation lights, placards, sanitation devices. A gasoline generator on a diesel boat brings the ventilation rules with it. Check each item aboard and record where it lives. Beneath the federal floor, a separate layer of what prudence adds. And a declarable inventory for clearing in abroad, shared with an official as plain text. BRIEFING — A passenger walkthrough written from your own gear map: where things live on this boat, in the words you recorded; a MAYDAY card with your vessel’s name, call sign, and MMSI filled in; the crew-overboard drill — shout, point, throw, press; and the house rules: PFDs, tethers, and jacklines at night, offshore, and in heavy weather. BEFORE YOU GO — A predeparture checklist drawn from her manifest, not a laminated generic: the blower on a gasoline inboard, the jacklines on a sailboat, the generator’s strainer, with the fuel and water estimates and the flare and extinguisher dates printed on the lines. Checks reset with the date, and the float plan is a tap away. MAINTENANCE — Service intervals seeded and filtered to her systems: twins get port and starboard lines, each fuel separator its own. Hard legal expirations come preset — documentation renewal, EPIRB registration, flares, extinguishers. Engine items come due at whichever arrives first, the months or the hours on the meter. Every item says what the job is: replace, inspect, test, clean. A 60-day lookahead shows what needs the skipper’s attention, and four ledgers — fuel, work, ownership, cruising — tally what she costs over any dates, set against last year, and export as CSV or PDF. LOG — The daily cruising log: legs and lay days, the persons aboard, voyages that collect entries until you end them, distance run, hours under way and engine hours, weather, a journal, and the day’s photos, kept on the device. Fuel and water estimates refuse to guess: top off or enter a measured level and the arithmetic runs from there; the gauge outranks the arithmetic. ON PASSAGE — Log the departure as you leave; every day at sea counts toward the voyage and the water until you tap Arrived. At each change of watch, log the time in local or UTC, the position from the GPS or typed as on a chart, course and speed, wind, sea, sky, sails, engine, and who kept it. From the second fix on, the log works out the speed and course made good, and the barometer — typed, or read from the phone’s own — shows its trend in the forecast’s words. HER FLEET — More than one boat, each with her own complete book. Export the book to a file you control and import it on a new phone, or switch on iCloud sync and every device signed into your Apple ID keeps the same fleet, through your own iCloud. Fully offline. No account, no subscription, no server of ours, no tracking; nothing you enter leaves your device unless you export it or switch on iCloud sync, which keeps it in your own iCloud. Your location is read only when you tap Fill from GPS on a watch — one position, into your log, never in the background. Manifest checks against the federal minimums — state law can add to them — and it prepares you for, never replaces, the free Coast Guard Auxiliary Vessel Safety Check. An aid to seamanship, not a substitute for it. May you find a rainbow’s end and treasure found wherever you sail or set your anchor. Apps for sailors, by sailors.

What a voyage cost. Every fill, repair and expense can name its voyage. A fourth ledger, Cruising expenses, holds provisions, meals ashore, fees, transport ashore and moorings. The Voyage expenses page, after the voyage card in the Log, shows the total, the cost per day and per nautical mile, and each category. What the boat costs. The four ledgers share one Expenses tab. Its first page totals fuel, work and ownership for this month, year to date, last year, all, or dates you choose; add cruising expenses with a tap. Compare any period with another, the same dates last year to start. Export the page as a CSV or a PDF. Every entry, any dates. Each ledger and the log show every entry in the dates you choose. Tap an entry to correct or delete it. Deleting anything now asks first. Measure a tank. Measure, beside each tank on the Fuel Log, takes the gauge by quarters or in gallons. The fuel estimate runs from that reading. Photos on the day. Add up to 12 photos to a day in the log, from the camera or your library. With iCloud sync on, they reach your other device. Sea service. A Sea service page in the Log counts days of service by year for the Coast Guard form: four hours or more under way, with the waters for each leg. Share the summary as text. You attest the time. A track for your chart app. Share as GPX, on the voyage card, sends the positions from the voyage's watches as a track. Maintenance says what the job is. Each item starts with its job: replace, inspect, test, clean, exercise, service or renew. Belts, the heat exchanger and its pencil zinc, and spark plugs have separate lines for inspection and replacement. Dates you recorded stay where they were. Finding your way. Every page has a name. The Index lists every page and finds one by name. Entry forms open over the page, and a link to another page leaves a way back. Update both devices together. A device on an older version that edits a boat saves her without the new ledger and photo lists.
