Best iPhone Notes App for Harbor Pilots

Harbor piloting is applied precision navigation in constrained environments. You're responsible for vessels worth tens of millions of dollars, cargoes worth as much or more, and the safety of the waterway and its users — all while working with ship's crews you've never met before, in conditions ranging from flat calm to storm force visibility.

Your local knowledge is your primary tool. Notes keep that knowledge organized, current, and accessible.

What Harbor Pilots Need to Capture

Underkeel clearance observations. Actual bottom conditions, shoaling reports, dredging activity. The channel that showed 40 feet last month may be 36 feet today if a storm has moved sediment.

Berth and terminal conditions. Berth construction that affects approach angles. New fender positions. Bollard line configurations. Terminal developments that change your maneuvering options.

Tidal and current observations. How the ebb and flood behave at specific points — the eddy near the turning basin that affects steering at low water, the set and drift through the channel narrows. These local observations supplement the current tables.

Vessel behavior notes. How specific vessel classes or types handle in your port's conditions — wide-beam container ships in cross-channel current, LNG carriers in wind. Notes from each pilotage build your vessel behavior library.

Regulatory and administrative notes. Bridge clearance notifications, channel closures, temporary restrictions, VTS frequencies, port entry requirements. Current information that changes frequently.

How Nemos Works for Harbor Pilots

Channel Condition Notes

"Channel update 2025-03-15: Main channel, inner section: shoaling reported near green 14 marker. Port authority dredge survey pending. CAUTION: reduce UKC allowance and consider tide window for deep-draft vessels until survey complete. Turning basin: new pile cluster on NW corner (temporary construction material staging). Marked with unlighted buoy — confirm with VTS before inbound."

Berth and Terminal Notes

"Northside Container Terminal — notes (updated 2025-03-): Berth 3: new foam fender system installed Jan 2025. Wider standoff than old system — approach angle adjustment required. First few berthing on this fender: slow approach and test. Berth 4: approach restricted — construction barge moored on east end of dock until April. Effective berth length 250m (was 320m). Tug staging: 2 tugs standard for large ships. Tug #3 (Assist) recently overhauled — better power than before."

Tidal and Current Observations

Personal notes on behavior at specific locations:

"Main channel narrows — current behavior: Spring ebb: set N-NE up to 2.5 kt at peak. Peak approximately 2 hrs before LW. Effect on inbound: significant cross-set through narrows — allow for set or compensate with heading. Effect on outbound: favorable — ebb assists departure. Eddy: turning basin S corner at mid-ebb creates clockwise eddy. Affects stern swing for eastward berths."

Vessel Behavior Notes

"Container ship class (UL-class, >14,000 TEU) notes: - Maneuvering at slow speed: minimal rudder effect below 4 kt — use bow thruster or tug. - Wind sensitivity: >25 kt beam wind causes significant leeway — adjust for. - Turning basin: minimum 580m turning radius with wind. 600m preferred. - Docking: spring line first on ebb current — holds the bow in."

FAQ

Q: How do I keep my channel condition notes current? A: Review and date-stamp updates after each pilotage. Add a "last verified" date to condition notes. Outdated notes are worse than no notes — clearly mark observations that need verification.

Q: Can I use voice dictation while on the bridge? A: During transit, your full attention must be on the pilotage. Notes are for before boarding (preparation) and after disembarking (observations). Never let note-taking distract from navigation.

Q: What about emergency notes during an incident? A: In any emergency, navigation and vessel safety come first. Notes come after the vessel is safe and the incident is stabilized.

Q: How do I organize notes for a port with 15 different berths? A: One note per terminal or berth cluster. A master "Port Conditions" note for channel and waterway updates. Cross-reference berth notes when conditions affect approaches.
