Bridge Con: Officer of Watch

Offline tides for 5,900 ports with alerts before high and low water, 35 swipe checklists, GMDSS distress steps and celestial navigation - made by a Captain.

Bridge Con is a toolkit for the officer of the watch: the tide, the checklist, the radio procedure and the sight you need on watch - offline, in plain words, in English, Ukrainian or Russian.

TIDES - 5,900 PORTS, OFFLINE

• High and low water, the curve and the height now, for any day
• Search by port, local name or UN/LOCODE - Hamburg, Antwerpen, Rotterdam find the stations around them
• Tidal window for the height you need (UKC or air draft)
• Alerts before HW and LW and when the fast rise or fall begins - set for alongside, at anchor or underway
• Own harmonic engine, checked against NOAA: median 0.3 minutes and 1 mm on 80 ports

BRIDGE CHECKLISTS

• 35 checklists, 397 points - watch handover, departure, arrival, pilot, anchoring, restricted visibility, heavy weather and 13 emergencies
• Every point with a short how-to
• Swipe right - done; left - postpone; postponed points come back at the end
• Share the record when you finish

GMDSS

• We are in distress, we received an alert, cancel a false alert - one decision at a time
• The MAYDAY written with your ship's name, call sign, MMSI and position, ready to read out
• Urgency, safety, tests, sea areas and frequencies

VESSEL IDENTIFIER

• Tap the lights you see, get the vessel, her heading and what to do - with the COLREG rule

CELESTIAL NAVIGATION

• Sky, almanac, ABC tables and sight reduction

PORT INFO - 3,000 PORTS

• Position, water density and your own notes for every port, on a world map
• The port plan, water side only: basins, berths and the fairway
• Pilotage and where the pilot boards, VTS and radio, drafts and depths

IALA BUOYAGE

• Every mark of regions A and B as a drawing, with its light at night and a photo of a real one
• All marks on one page, to check which is which

IAMSAR - SEARCH AND RESCUE

• Person overboard and a distress alert received, step by step
• Search patterns played out, the legs worked for your track spacing
• Every situation from on scene to rescue, in plain words

AND MORE

• ETA by great circle or rhumb line, in ship's and port time
• Rest hours against MLC and STCW, with a month editor and an inspection-ready PDF
• Compass error and the compass book, true wind from the anemometer or the sea state, air draft from the drafts as read
• A private journal: notes by voice, contract days, ports, documents
• Everything syncs through your own iCloud to your other iPhones
