Passage Plan

Passage Plan: пересечение Ла-Манша

Планирование маршрута яхты — основа безопасного перехода. Ниже представлен реальный passage plan для пересечения Ла-Манша, который может служить образцом для passage planning yacht.

Vessel: ARMONIA (Gib Sea 43, 2003)

Date: 18 January 2026

Boat speed (STW for planning): 6.0 kn

Time standard: UTC

Navigation: Paper chart + GPS/plotter + AIS Class B (NO radar)

Маршрут яхты: планирование waypoints

2. Route (WGS84)

Карта маршрута яхты с нанесёнными waypoints — обязательная часть подготовки. Каждая точка выбрана с учётом правил плавания в зонах разделения движения (TSS) и приливных течений.

3. Legs — CTS (your chart work)

—

4. Watchkeeping / AIS

– High traffic watch: WP3 → WP4

– AIS Class B ON, monitor targets, check CPA/TCPA, early and clear avoiding action.

– Maintain proper visual lookout at all times.

—

5. Safety Brief

– Lifejackets on deck.

– Jackstays / tethers at night and in rough weather.

– MOB: shout, point, mark, throw buoyancy, recovery plan.

– Fire/Flooding: extinguishers, seacocks, bilge pump, Mayday/Pan-Pan.

– Engine stop / fuel shut-off / emergency tiller.

– Warm clothing, headtorch, hydration.

Пересечение зоны разделения движения

6. TSS / Crossing Brief (WP3 → WP4 area)

– Cross traffic lanes close to 90°.

– Do not enter separation zone.

– Early avoiding action, keep clear of commercial traffic.

– AIS monitoring + visual lookout.

– If visibility reduces: reduce speed, sound signals, engines ready.

Парусная навигация в зонах TSS требует особого внимания к правилам плавания МППСС-72. Яхта обязана пересекать полосу движения под углом, близким к 90 градусам, и уступать дорогу судам, следующим по установленному маршруту.

—

7. Arrival Brief

– Prepare fenders/lines early, crew roles allocated.

– Position check, depth/tide check, lights identified, VHF call prepared.

– If no safe entrance: hold position in safe water or divert to Cherbourg.

—

8. Restricted Visibility / Fog

– Reduce speed to safe speed.

– Sound signal (motorsailing): one prolonged blast every 2 minutes.

– Extra lookout, AIS monitoring, frequent position fixing.

– If below safety limit near approach: hold position or divert to Cherbourg.

9. Weather Timeline (18–19 Jan 2026)

Key times (UTC): Sunrise 0800, Sunset 1650.

19 Jan: fronts affect the Channel, pressure drops, wind freshens and sea state worsens.

10. Tides — Standard Ports and Secondary Port (St Vaast)

Portsmouth — Standard Port (UTC)

Mean Levels (m): MHWS 4.7, MHWN 3.8, MLWN 1.9, MLWS 0.8.

TIDES +0020 Dover; ML 2.8.

Cherbourg — Standard Port (UT−01 on table; converted to UTC)

Mean Levels (m): MHWS 6.4, MHWN 5.0, MLWN 2.5, MLWS 1.1.

St Vaast La Hougue — Secondary Port (from Cherbourg)

Time differences (from table):

– Reference HW 0300 / 1500: +0115

– Reference HW 1000 / 2200: +0045

Height differences (from table):

– HW: +0.4 m

– LW: −0.1 m

Time method: St Vaast HW time obtained using Crocodile triangle between the reference times.

Place for Crocodile triangle (interpolation diagram):

Results used in this plan (UTC):

– St Vaast HW 0830, height 6.3 m

– St Vaast HW 2054, height 6.2 m

St Vaast notes: TIDES −0240 Dover; ML 4.1; Duration 0530.

St Vaast tidal gate (HW 2054)

Gate: HW − 2h 15m to HW + 3h

– Opens 1839 UTC

– Closes 2354 UTC

11. Streams — Dover reference and Computation of Rates

Dover tides (18 Jan, UTC)

– LW 0539 1.5 m

– HW 1052 6.0 m

– LW 1757 1.4 m

– HW 2312 6.2 m

Computation:

– Rate_comp = Spring_rate × F

– Cycle 1: Range = 6.0 − 1.5 = 4.5 m; Mean Spring Range = 6.0 m; F1 = 0.75

– Cycle 2: Range = 6.2 − 1.4 = 4.8 m; Mean Spring Range = 6.0 m; F2 = 0.80

13. Ports of Refuge

– Legs 1–2: return Portsmouth.

– Leg 3: return Portsmouth until halfway Leg 3.

– After halfway Leg 3 and further: refuge Cherbourg.

– Leg 4–5: refuge Cherbourg.
