Navigation · IALA A & B · Night channel focus
Leave-to lateral marks, cardinals, and junctions cold—before you cast off. Study enamel cards, scrub real light rhythms, grade channel drills, and run your own home-waters approach strip under IALA A or B.
Deck at a glance
Spin the brass helm, lock a region, then work enamel laterals, preferred-channel junctions, cardinals, isolated-danger, safe-water, and special marks—with live flash characteristics you can scrub before fog rolls in.
Pick a region → study illustrated marks with live light-flash playback → rehearse junction scenarios → build a home-waters approach strip.
01 — HUB
Lock IALA A or B once, then browse enamel-style cards for laterals, preferred-channel, cardinals N/E/S/W, isolated-danger, safe-water, and special marks with body, topmark, and light color.
02 — LIGHTS
Open any mark and scrub its real characteristic as an on-device blink preview—period, duty cycle, and waveform—so night recognition sticks before you see the real buoy.
03 — DRILLS
Channel diagrams throw junctions and bends; tap Port or Starboard leave-to (or safe-water behavior) and get an instant score, rule callout, and corrected overlay path.
04 — STRIP
Drag seeded or custom marks into sequence, annotate mile notes, and flip the strip full-screen as a pre-departure mental rehearsal deck for your inlet or marina.
05 — SPLIT
Same junction silhouette, simultaneous enamel cards, one-tap region swap—so red-right versus red-left differences lock in without flipping textbooks.
06 — FOG
Play power, sail, and mark-at-anchor sound patterns, quiz pattern-to-meaning, then pin missed Light Rhythm boards into a Weak Signals pile for crew brief share-outs.
Why it exists
BuoyRead Channel Kit is the cockpit rehearsal studio for new boaters, sailing-school students, kayak tour leads, and harbor skippers who cannot afford a red-right guess in fog.
Dense COLREGS/IALA buoyage becomes a tactile, scenario-graded skill you carry to the helm—enamel cards, timed flashes, scored junctions, and a Home Stretch strip you run mentally before departure.
