One crew aboard, each with a job.
Shimbiri connects your boat’s instruments, manuals and live data, and gives each job to an officer. Ask the Captain anything; the right officer answers. Built and proven in Australian waters first.
The Captain
One place to ask. The Captain answers from your boat’s own instruments, manuals and logs, and brings in the right officer.
- Answers from your boat’s own data, manuals and history
- Weather, systems, manuals, maintenance and crew in one conversation
- Attach a photo and ask about it
- Ask in WhatsApp as well as in the app
- A briefing morning, midday and evening, or whenever you ask
- The morning briefing covers position, batteries, tanks, weather and the last 24 hours
- Connect your own AI assistant: it reads the boat, and asks you before it changes anything
The Weather Officer
Several forecast models side by side, a flag when they disagree, and a plain read on the passage.
- GFS, ECMWF, AIFS, ICON and UKMO compared side by side
- Checked against your own instruments and the nearest weather station
- Bureau of Meteorology warnings and rain radar
- Observed lightning, where that satellite picture covers the passage.
- The Bureau’s coastal waters forecast for your zone, word for word as issued
- Sunrise, sunset and moon times for where you are
- Anchor watch with an alarm to your phone
The Cruise Officer
What is this passage for, and so: do we go, when, and is it still the right plan? Race Officer when you race.
- Passage plans on your boat’s own polars
- Departure times compared passage against passage
- Tide gates for bars and channels, with window times
- A bar register for Queensland and New South Wales, with each bar’s local cautions
- Wind against tide flagged on the legs where it happens
- Under power: legs planned at motoring speed, with fuel burn from your own fills
- Race mode during a race, cruise mode the rest of the time
The Chief Engineer
Engine, batteries, tanks and bilge, live from the boat, with alarms to your phone.
- Engine: RPM, oil pressure, temperatures, hours
- Batteries: voltage, state of charge, charging and runtime
- Tanks: fuel and water in litres, with range
- Bilge and alarms, with critical engine alarms sent to your phone
- The alarm history
- History of any reading by the hour or the day: heel, batteries, solar, tanks
- Hours and miles left under power, from the fuel aboard and your own burn
- The boat’s internet link and Starlink data in one place
The Bosun
The service schedule, defects, spares and certificates, kept in one place.
- Service schedule by engine hours and by date
- Defects recorded with their history and the manual’s procedure
- Stores and spares, with days remaining
- Boat certificates and the Category 1 compliance checklist
- Service and repair records, filed from your receipts
- Your yards, mechanics, marinas and insurers, gathered from your receipts, each trade editable
- A readiness check before a passage
The Purser
A search engine for your boat, answered from your own manuals, policies and receipts.
- Upload manuals as PDFs; scanned pages are read too
- Search every manual on the boat at once
- Answers with page references, opened at the exact page
- Search with a photo, or ask by voice
- Search your receipts, service records, notes and suppliers too
Signals
Crew, conversations and the calendar, with the boat as a member of the chat.
- Crew threads and group chats, with the boat as a member
- Ask the boat in WhatsApp, and she answers
- The crew roster, with each person’s role
- Crew list with certificates and expiry badges
- Events and a crew calendar you can subscribe to
- Photos from the crew published to the boat’s tracking page
A real plan, Moreton Bay to Mooloolaba.
This is a real plan from Shimbiri, run on 16 October 2026 for a Saturday departure, on the boat’s own polar and the forecasts held at the time.
Moreton Bay (Manly) to Mooloolaba
- 51.0 nm, about 5.3 hours on the boat’s polar
- Worst leg: GO, with the highest sea about 2 m near the Mooloolaba approach
- Mooloolah River bar: window 10:45 to 12:45 aboard on Saturday, high water 12:15
- Tidal streams checked on every leg; no wind against tide at the planned times
Full: weather, tides, tidal streams, bar windows and official charts.
A planning aid from stored forecasts, not for navigation. Check official warnings and use your own judgement.
For the whole crew.
The parts of Shimbiri that belong to every officer.
Systems and manuals, for the crew
Give each crew member access to the boat’s live systems and manuals, and choose who sees what. Engine, batteries, charging, tanks and bilge are shown on a phone or PC wherever you are, and every manual on the boat can be searched at once.
The Apps →WhatsApp and crew threads
Ask the boat in WhatsApp, and she answers. Crew threads and group chats in the app include the boat as a member.
Communications →Certificates, with expiry
Shimbiri keeps the crew list with each person’s certificates and expiry dates, and shows at a glance who is in date and who is not.
Crew →The COLREGs, learned
Every rule as a short lesson, with flashcards for lights and shapes, a quiz and the sound signals.
COLREGs →Day and Night
One switch for the whole app. Night is a red palette that keeps your night vision on watch.
On every screen aboard
Phone, tablet and computer. Beta testers get the Android app; on iPhone, add it to your Home Screen.
