Three public domain maritime references in one offline library. An independent reference app. Not affiliated with, endorsed by, or sponsored by the US Coast Guard, the USCG Auxiliary, NGA, or the Department of Homeland Security. It reproduces their public domain publications, which are also free at navcen.uscg.gov. Free forever. No ads, no subscription, no account, no data sharing. NAVIGATION RULES HANDBOOK (COLREGS AND INLAND) The complete International Rules (72 COLREGS) and Inland Rules (33 CFR 83), presented side by side rule by rule exactly as the official handbook does, with a quick toggle to show only International, only Inland, or both at once. Parts A through F plus Annexes I through V. This is the whole rules of the road text, not a summary or a quiz bank. BOAT CREW SEAMANSHIP MANUAL The full manual: boat handling, towing, search and rescue, heavy weather, navigation, sound signals, anchoring. Every chapter, fully searchable. INTERNATIONAL CODE OF SIGNALS (NGA PUB 102) All 40 signal flags (26 letters, 10 numerals, 3 substitutes and the answering pennant) with their single letter meanings, plus the two letter Distress, SAR, Maneuvering and Weather sections. WHO IT IS FOR โข Captains preparing for a USCG OUPV (six pack) or Master license โข Anyone studying the rules of the road for a licence exam โข Coast Guard Auxiliarists working through Boat Crew Member or Coxswain qualifications โข Recreational boaters and sailors who want the real rules at a glance, not a paraphrase โข Anyone responsible for the safe operation of a vessel WHY THIS ONE Most navigation rules apps charge between four and sixteen dollars for the text alone.

Each with its use case, the verbatim Boat Crew procedure, and a deep link back to the manual section that covers it.
