COLRIN Flashcards
COLRIN: applicability
Def: Large Vessel
- ≥ 20 m
- vsl engaged in towing/pushing/assisting large vsl
- pax vessel approved > 12 pax (whether or not) -> shows yellow diamond if < 20 m
- Ferry crossing fairway
- vsl engaged in fishing
Def: Seagoing vsl
large vsl underway to/from sea => lights and shapes according COLREGS
Def: Oversized Vessel
Seagoing vessel constrained by draught
Def: High Speed Vessel
Large Vessel that can go > 40 km/h = 21 kn
(whether or not!)
Def: Convoys
Towed convoy: one or more vessels, towed by one or more tugs
Pushed convoy: Rigid group of one or more vessels, placed in front of a pusher.
Side-by-side formation: Two or more vessels coupled side-by-side.
A tow or convoy of small vessels remains a small vessel
Def: Small Vessel
any ship < 20m, i.e. not a large vsl
=> fast motorboat: can go faster than 20 km/h
Fast motorboat:
requirements
- registration number
- dead man’s cord
- fire extinguisher
- life jacket
- > 18 y.o. & license
General rules
- Stationary: anchored or moored
- Fairway: That part of the waterway that can be used by shipping.
- Reduced visibility: Conditions in which visibility is reduced due to fog, mist, snow, …
- Skipper is always responsible, and must be on board
- Precautions: Even where no special rules, the skipper shall take all the precautions required to exercise vigilance and good navigational practice to avoid danger and damage. Good seamanship
- Conduct in special circumstances: To avoid imminent danger, the skipper shall take all the steps required by the situation, even if this entails deviating from these regulations.

On the stern:
Name, homeport, countrycode:
N = Netherlands
Small VSL:
name of ship
inside: name of owners/place of residency
Large MV:
lights
Small MV (7-20m):
Lights
Tug:
lights
unlike COLREGS: length of tow irrelevant
3 mastlights => more than 1 tug towing same object
daysignal: cylinder white/black/yellow/black/white
Towed object:
lights
if towed object ≥ 110m => 2 white allround lights (1 fwd, 1 aft) at same height
Pushed convoy:
lights
if the pushed barges are wider than the pusher they must also exhibit stern lights
If pushed convoy < 110 m or beam < 12m => regarded as normal MV
Side-by-side formation
Lights
Large SV:
lights
Motor sailing @ day: black cone pointing downwards

Sound Signals
COLRIN - general
VHF
Annex 9 lists fairwys where 2nd VHF is mandatory and where radar use is obligatory in reduced visibility
High Speed Vessel
Gives way to any other ship; even if proceeding slower
2 yellow flashing lights (day/night)
oversized seagoing
all ships must give way
3 red all-round lights / black cylinder (= COLREG)
COLRIN
General Principles
- Vessels are only allowed to meet or overtake, if there is suffient space.
- Do not create dangerous situations. (Elbe 5)
- If you must give way: change course (turn) or slow down (or both),
do it in time and clearly. Avoid passing in front of the other vessel.
(Elbe 5) - Stand-on vessel: keep your course and speed, but always avoid a collision
Important: If you desire co-operation of another vessel: prevent the other vessel having to make sudden course or speed changes
And: Communicate!
COLRIN
3 possible ways to manoevre
- Change course (‘turn’)
- Give way: change course (turn) and/or slow down
- Desire co-operation
Important: If you desire co-operation of another vessel: prevent the other vessel having to make sudden course or speed changes
And: Communicate!

Rules for Berthing & Waterway Signs
- Avoid hindering traffic while berthing (mooring or anchoring)
- Waterways signs regulate berthing.
- Minimal distance to a moored ‘cone’ vessel: resp. 10, 50, 100 m
- Moored ashore vessel should allow another vessel to come alongside.
- Co-operation should be given when other vessel wants to depart. Or the vessel wants to (un)load.
