Glossary
Marine and app terms used in this manual.
Active Vessel — the boat AnchorQueen is currently tracking as yours. Set
it by dragging a boat onto the active slot in
Captain → My Vessels; it survives relaunch.
Airtime — how long you were off the water in a jump during a
Sea Sports session. Jump height is worked out from
it; on long kite jumps the barometer can raise the height.
AIS (Automatic Identification System) — live position broadcasts from
nearby vessels. Jules can list the closest traffic
on request.
Anchor watch — keeping check that an anchored boat is not dragging.
AnchorQueen automates this from the SafeAnchor tab.
Anchor watch in 3D — the armed anchorage shown over 3D terrain: rings on
the seabed, the swing so far, the live boat and the drift forecast, with the
marine weather on the page. Opened from the glowing 3D button on the
Anchor Watch chart.
Armed — the alarm state in which the anchor watch is actively
monitoring your position. The watch arms itself once the anchor commits —
there is no separate Arm button.
ATT (App Tracking Transparency) — Apple's first-run prompt asking
whether the app may track activity for ads. Declining does not limit any
AnchorQueen feature; a PRO subscription removes ads entirely.
Beaufort scale — an empirical measure relating wind speed to observed conditions
at sea or on land (levels 0 to 12). Used by the Sea State card
and the 3D Ocean in Passage Replay to drive wave height,
steepness, whitecap foam, and spray.
Base map — the underlying chart style. Pick it in the chart's
Chart Layers → Maps panel, not in Settings.
Captain's Library — the unified manager for saved routes, waypoints,
captain's marks, and recorded passages. Opened from the side menu's
Capt's Routes entry — see [Chart → Captain's
Library](chart.html#captains-library).
Captain's mark — a position you saved on the chart. Marks appear in
the Capt's Notebook Pin Carousel and can carry
photos, voice memos, and a signature.
Chart region — a packaged offline map area you install from the
Store. The offline-first source of soundings and
vector charts.
Chart-transfer strip — the slim glass bar at the bottom of every screen
that shows a chart download or automatic update: progress, what is holding it
back, INSTALL when it is ready. Tap it to open My Maps. See
Charter base — the marina a charter boat is let from and returned to.
It is the position shown for every boat in
Renting a boat here — a base, never a live
position, and never AIS traffic.
Charter partner — the company a charter boat is booked through:
BOATAROUND or Click&Boat. Which one leads depends on the country; the other
appears as Also on …. See Two charter partners.
Charter plan — a saved charter search: destination, Saturday-to-Saturday
week (optionally ±3 days), guests, cabins, category, licence, budget and
sort. Saved from the charter planner
and re-run from the Notebook's Charter panel; it stores the question,
never the boats, so reopening it shows current availability.
Compare (charter) — up to four charter boats laid out side by side —
price, week total, length, cabins, sleeps, built, engines, rating, licence,
base, distance — with the best value in each row highlighted. Ticked from
any charter list; see Compare boats.
Community route — a Sea Sports route, planned or recorded, that a captain
chose to share. Other captains see it in Discover
near where it starts; the shared copy has the ends of a recorded track
trimmed off. See Share a route.
Comfort index / score — a sea-state rating (e.g. Moderate Sea State)
shown in Meteo → Events. Tap it for the comfort
history and forecast.
Command Palette — the dual-mode search overlay opened from the search
icon: a Map Search tab (places, harbours, seamarks, saved waypoints,
with recent history) and a Features tab. See
Course Predictor — the dashed line drawn ahead of your boat showing
where you will be six minutes from now. A toggle in the chart's
Chart Layers → Navigation tab (on by default).
Crosshair / reticule — the on-screen target marker that reports depth
at the chart center; toggle in Discover.
Datum (tidal) — the reference level tide heights are measured from
(e.g. MLLW, Mean Lower Low Water). Shown as a badge on the
Meteo station card; subtract it to estimate
real clearance.
Depth-aware route — a route that is planned to keep you in safe water
for your boat. Jules plans these on request.
Direct It — nudging the set anchor a chosen distance ahead of the
boat along your live heading, using a slider — see
SafeAnchor. No bearing is typed.
Dock to Dock — the guided A→B route-build mode (departure and
destination slots) as opposed to free-form drawing. See
Document Vault — a private 50 MB store on the
Captain tab for certificates, insurance,
and ship's papers (PDF / JPEG / PNG).
DOP (dilution of precision) — a GPS fix quality number. Lower is
better.
Douglas sea state — a 0–9 scale naming the sea by its wave height, from calm (glassy) through slight, moderate and rough to phenomenal. Sea Sports Plan shows it beside the forecast wave height.
Drifting — the alarm state when your boat has crossed the alarm
radius. The radar flashes and the alarm sounds.
EEZ / maritime zone — a sea-area jurisdiction (territorial sea,
Exclusive Economic Zone) belonging to a sovereign state.
Jules can tell you which one you are in.
Favourite ❤️ — a seamark, route, passage, Captain's Mark or past anchorage
you have hearted. It carries a ❤️ badge on the chart at every zoom, is listed
first in Search, and syncs with your account. See
Fishing effort — vessel-hours of active fishing, the metric behind the
Merconi fishing heatmap. Sourced from GFW.
Flotilla — multi-vessel remote anchor-watch for a fleet sailing
together: up to 10 vessels with Real-Time Remote or Pro, 100 with Max; joining
one is free. See Remote → Flotilla.
Full chart access — the 14 days that start with your account's first
chart download, during which every downloaded region works completely —
routing, navigation, Passage 3D, updates — even with nothing paying for it.
Afterwards such regions are view-only. See
GFW (Global Fishing Watch) — the open source behind the
Merconi fishing-effort heatmap. The app carries its
own GFW key.
Ghost Fleet — the live positions of other AnchorQueen captains shown
on the chart (distinct from the Voyage Ghost vessel below). A layer in
the Region Button Bar.
Ghost vessel — the semi-transparent vessel marker that plays back the
route during Voyage.
Grace period — the window (up to 90 days) after a chart-region
subscription lapses: the region stays viewable but automated routing and
updates pause. See Store.
Grounding alarm — a warning that the water under your keel has dropped
below your safety margin. Shows a red chart banner with Silence /
Dismiss. Unlike the drag and man-overboard alarms it is visual only —
it plays no sound; see SafeAnchor.
Heading — the compass direction your bow points, in degrees (0–360).
Holding score — a rating of how well an anchor will grip the seabed
at a spot, based on the seabed type. Ask Jules.
Jules Needs / Jules token — your daily AI allowance for
Jules. Buy bonus token packs (Deckhand / Navigator /
Admiral) in Store → Jules Needs.
Legend panel — a collapsible side panel that holds layer toggles on
the chart; minimize it to the Region Button Bar.
Live mode — the full-screen Sea Sports screen shown while a session runs: elapsed time, speed, your sport's figures and distance, with a hold-to-stop button and a water lock. See Sea Sports → Live.
Live Discover — the sidebar tally of nautical objects (lights, buoys,
harbours, anchorages, wrecks…) AnchorQueen collects as you pan the chart.
See Basic UI.
Meteogram — a multi-day graphical forecast; the third sub-tab of
Meteo. Its 3-day and 7-day ranges are a PRO
feature.
MOB — Man Overboard. The button on every map tab that drops an
emergency marker, starts return guidance, and records a recovery track.
See Basic UI → MOB and
NMEA — the standard sentence format marine instruments use to share
data. Connect a Wi-Fi gateway or Bluetooth pod in
Settings → NMEA; model-specific instructions are
OBIS — the live Ocean Biodiversity Information System database behind
Merconi marine-life pins. Networked, with the last
viewed area cached.
Officer — one of Jules's expert personas (e.g.
meteorologist, navigator). Selected from the pill row at the top of the
chat.
Open-water crossing — a stretch of a Sea Sports plan that runs further from
shore than is comfortable for your sport. Plan draws it with a dashed amber line
and lists nearby bail-out beaches. See
Pin Carousel — the row of floating captain's-mark chips at the top of
the Capt's Notebook chart, sorted nearest-first
to the chart center. Its leading count badge opens the Pin Manager.
Pin Manager — the sheet opened from the Pin Carousel count badge to
list, fly to, and delete saved marks (including bulk delete). See
Port of entry — a harbour with customs and immigration offices where
you can clear in to a country. Jules can find the
nearest ones.
Pre-arm ("Locking GPS…") — the brief step after you tap Drop
Anchor while the watch averages accurate fixes before committing the
anchor position. See SafeAnchor.
Public Beacons — the opt-in live positions of other AnchorQueen
captains, shown on the chart with an amber ring (your own flotilla shows
teal; raw AIS has no ring).
Reel — a short vertical (9:16) film made on your phone from the 3D
chart, with a link that plays it in any browser. Four subjects share one
reel: a recorded passage, a planned
route, an
anchorage — the armed watch or a past stay —
and a seamark fly-over. Every reel you make is
listed under My shares.
Region Button Bar — the bottom-left vertical capsule of minimized
legend-panel buttons. Zero-count categories auto-hide; the bar collapses
to a chevron.
Rode — the chain or rope connecting your boat to its anchor.
Safety Profile — optional SOLAS SAR / ISAF details (blood type,
emergency contact) on the Captain tab,
used when you raise a distress alert. Its SAR Ready badge lights when
the three critical fields are set.
Scope — the ratio of deployed rode length to water depth. More scope
holds better but lets the boat swing in a wider circle.
Sea Sports session — a passage recorded at full GPS rate while you
ride, sail, paddle or swim — seventeen sports from jet ski and kitesurf to
dinghy, rowing and freediving — with the figures that matter for the sport
(jumps, waves, tacks and gybes, stroke rate, pace) from the motion sensors
of your iPhone or Apple Watch. Started from the Voyage pill, Siri or Apple
Watch — see Chart → Sea Sports.
Seamark — a charted navigation aid such as a buoy, beacon, or
lighthouse. Jules can list those near you.
Server / Client — the two roles in
Remote monitoring. The server stays aboard; the
client goes ashore.
Significant wave height ($H_s$) — the mean wave height (trough to crest)
of the highest third of the waves in a wave spectrum, expressed in metres or feet.
Used across the Meteo tab and the
3D Ocean in Passage Replay as the primary measure of sea roughness.
Speed over ground (SOG) — your speed across the seabed, from GPS.
On the chart HUD the SOG readout colour-shifts as an early drag cue.
Sport route — a water-only route planned for a paddle, swim or board
sport, from a departure through optional stops to an arrival. It ignores depth
and uses the coastline built into the app, so very small islets and rocks may
be missing. See Sea Sports → Plan.
Story — a short video you compose from a Sea Sports session: its 3D film
plus your own photos and videos and title, stats and map cards. See
Stroke rate (spm) — paddle, oar or arm strokes per minute, measured
from the rhythm of the motion sensors during a paddling, rowing or swimming
Sub-mode — a switch inside a tab, shown as a frosted pill bar at the
bottom. The AnchorQueen chart has Route / Discover / Voyage; Merconi has Diving /
Discover; SafeAnchor has Anchor Watch / History / Radar.
Swing radius — the distance a boat moves around its anchor as wind
and tide change.
Tack / gybe — turning a sailing boat's bow through the wind (tack) or
its stern through the wind (gybe). A dinghy
Sea Sports session counts both from your
course against the session's wind.
Tile Engine — the Settings → Chart
option that chooses how map tiles are fetched: a three-tier offline cache
or direct streaming.
Tile pack — a downloaded bundle of chart tiles for offline use,
either cached on demand from the Chart tab or as
part of an installed region.
Track Style — the Settings → Chart
controls for how recorded tracks are drawn (solid or speed-gradient
colour, line width, opacity, fade).
Trackcam — the low camera beside you in the 3D replay of a Sea Sports
session; it moves in before each jump and circles you in the air. See
TSS (Traffic Separation Scheme) — IMO-designated one-way shipping lanes
divided by a no-go separation zone. COLREGS Rule 10 requires crossing
near a right angle and forbids anchoring in the zone (Rule 10(g)). AnchorQueen
draws schemes offline and alarms on violations — see
Turn card — the heading and distance instruction shown above the
ghost vessel during Voyage.
Under-keel clearance — estimated metres of water beneath the keel
(negative means aground). Drives the
View-only chart — a downloaded region nothing pays for, after your
14 days of full chart access have ended. It keeps drawing; depth-aware
routing, navigation, Passage 3D and automatic updates need a plan or the
region's subscription. See Store.
VMG (velocity made good) — the part of your speed that takes you
straight upwind or downwind. A dinghy session shows its best upwind VMG
when the session has wind.
Voice memo — a spoken note (up to 45 seconds) attached to a captain's
mark; plays back even with the silent switch on. See
Water Lock — the Apple Watch mode that ignores touches so water can't
press buttons. AnchorQueen turns it on when a
Sea Sports session starts on the watch; press and
hold the Digital Crown to unlock.
On the iPhone's Live mode the same idea is the
water lock drop icon: the screen ignores drops and spray, and the stop
button becomes Hold to unlock (2 seconds).
WoRMS — the World Register of Marine Species, the taxonomy source that
enriches Merconi species pins with common names and
reference links.
