1. Before Leaving Home

 1.1 Weather Forecast

Weather forecast sources:

[ Contents ]

1.2 Tides

Check the times of high/low water at one of the sources listed below. You should then know if you will be sailing with/against the tide – it will be more difficult to return if you will be sailing against the tide.

Tidal data sources:

Boat’s draft: When calculating critical tidal heights be aware that the swell may mean that the actual water level will fluctuate above and below the calculated level.

1.3 Stena HSS

Check departure and arrival times and stay out of its way! If you impede the HSS you, not the club, will face a severe fine (approximately €5,000).

2.3 Ruffian

Ensure compliance with the Irish Ruffian Association’s Safety Checklist.

[ Contents ]

2.4 Weather Forecast

Check it again before you depart.

Offshore winds: An offshore wind becomes considerably stronger as you sail away from the shore. Ensure that your sails are appropriately reefed if necessary.

[ Contents ]

2.5 Passage Plan

By law (SOLAS) the skipper must prepare a written passage plan before departure, use the Captain’s log. This may be quite basic if just sailing in Dublin Bay. Consider:

2.7 Skipper’s safety briefing

The skipper should inform the crew about: locations of safety equipment, lifelines, lifebuoys, flares, fire fighting equipment, first aid kit, introduce the first aider, ask if any crew have medical issues.
Discuss hazards: boom, winches, sheets, foredeck, gas (including cut off switches), fires (engine + general).

Also, brief at least one other person about: launching liferafts, man overboard procedures, anchoring/mooring/berthing, the use of communications equipment, GPS + navigation lights, controlling the engine, location of grab bag, how to navigate to a place of safety. Jointly plan places of refuge in case of bad weather.

3 On the Water

3.1 Personal safety

[ Contents ]

3.2 Collisions

Keep a good lookout at all times (this includes monitoring VHF channel 16, and radar, if fitted) and ensure that the way is clear before performing any manoeuvres.

[ Contents ]

3.3 Ship’s log

Update the log every hour if making a passage. (e.g. Glenans Cruising Logbook).

[ Contents ]

3.4 Engine checks

Check the engine + fuel level regularly. Turn the greaser every couple of hours when the engine is running.

[ Contents ]

3.5 Bilge check

Check the bilge periodically.

[ Contents ]

3.6 Gas cooker

Check regularly for fire, and for the smell of gas in case there is a leak or the flame is extinguished. Be very careful of boiling water – especially in rough seas and during manoeuvres. Stack delft and cutlery away straight after use. Do not leave the gas cooker unattended while it is lit.

[ Contents ]

3.7 Minimum age levels

By law persons under the age of 12 may not operate or control a craft with an engine rating of more than 5hp (3.7kW).

[ Contents ]

3.8 Alcohol/Drugs/Smoking

The master or owner of a pleasure craft must not operate or control or allow another person to operate or control the craft while under the influence of alcohol or drugs.
Any person on board a pleasure craft must not consume alcohol or drugs in circumstances that could affect the safety of other persons.
Smoking is not permitted below deck due to the fire hazard.

3.9 Pollution Prevention (MARPOL)

In a nutshell: Don’t throw anything into the sea!
Details:

3.10 Anchoring

[ Contents ]

3.11 Night sailing

Beware of the risk of hitting (almost invisible) containers at sea. Ensure that all crew on deck use safety lines. Have an emergency plan in place. Using bright lights below deck can ruin the crew’s night vision.

[ Contents ]

3.12 Monitoring the weather while cruising

If the barometer shows a drop of more than 4 hPa in 1 hour, there is lots of wind on the way!! A reduction of 2 hPa per hor for at least 3 hours means that a gale is on the way!
Keep monitoring the barometer after a depression passes: a secondary depression may be rapidly approaching – these are often more violent! Warning signs: Cirrus clouds, a halo around the sun or moon and a dip in pressure.

Forecasts on VHF

Irish Coast Guard radio stations make a prior announcement of weather forecasts on Marine VHF Radio channel 16 and then broadcast the forecast on the named relevant VHF Radio working channel. Sea Area Forecasts are broadcast every 3 hours beginning at 0103 local time, i.e. 0103, 0403, 0703, 1003, 1303, 1606, 1903, 2203 local time.
Gale Warning broadcasts are also preceded by an announcement on Marine VHF channel 16. They are broadcast on receipt and are repeated at the next one of the following times: 0033, 0633, 1233 and 1833 local time.

See procedures at www.safetyonthewater.ie/upload/general/8790-4.pdf
If a lifejacket is inflated, do not repack t in case somebody thinks that it is safe to use!

Survival times:

[ Contents ]

3.16 Strong winds

If running in strong winds (e.g. 40 knots) beware that the apparent wind will mean that you will experience about 33 knots. If you turn to windward and sail at 6 knots the apparent wind will rise to about 46 knots, i.e. the force on the sail will double!
All gear below deck should be secured (in all weather conditions).

[ Contents ]

3.17 Rigging a preventer

When running, it is safe practice to rig a “preventer” in order to prevent accidental gybes. This is a line rigged from the cockpit (where it can be quickly released), through a forward cleat and then outside the boat back to the end of the boom.

[ Contents ]

3.18 Motoring to/from marina/harbour

Always have the sails ready for use, in case of engine trouble.

[ Contents ]

3.19 Raising/lowering and reefing the mainsail

It is safer to be ~ 10 degrees off the wind (rather than head to wind) to stop the boom from swinging from side to side.

[ Contents ]

4 After Sailing

4.1 Captain’s log

Update the log.

4.2 Damage/Repairs

Report any damage or required repairs to the maintenance officer.

4.3 Shore Contact

Ensure that you tell the shore contact that you have reached your destination or returned safely!

5 Information for Skippers

5.1 Ruffian tender

Ensure that the Ruffian tender is in good condition, not overloaded (make several trips if required), contains oars + a bailer, and that all occupants are wearing lifejackets.
A handheld, waterproof VHF radio, mobile phone and whistle should be aboard.
Be aware of wind and tidal conditions.

[ Contents ]

5.2 Documents

If you are cruising abroad you should bring your ICC card and ensure that the vessel’s VHF license and insurance certificate are aboard.

5.5 Engine failure

Judge the situation if you have enough space/sea-room to make a quick check of the engine.

Engine checks

 Engine will not turn over

Hand starting:

The most likely cause is that the battery is not able to deliver sufficient current to energise the starter motor. Less likely causes would be electrical problem with the circuit between key and solenoid, starter motor itself is faulty or the engine seized.

In this case switch to the other battery and try once, if the engine still won’t turn over switch to both and try again. If the engine still won’t turn over release the cylinder compression by pushing up the lever located at front top of engine on rocker cover. If the engine still won’t turn over the starter motor/ solenoid may be faulty and the engine will have to be turned over by hand to start it. Set the throttle to half.

A starting handle is connected to engine and with compression lever up the engine is turned over as fast as possible by turning the starting handle, when maximum speed is reached flick down the decompression lever and the momentum in the flywheel should be sufficient to compress the air in the cylinders to make the engine fire and start.

 

Engine will turn over but not start

The most likely cause would be problem with fuel. The fuel system consists of a storage tank connected to a low pressure “lift” pump connected to the high pressure injector pump and on to the injectors. Dirt or air in any of the fuel lines will cause starting problems. Dirt from the tank will be caught in a filter on the low pressure line which can be removed and cleaned.

After the filter has been replaced the line will need to be purged of air which can be done with a lever designed for this purpose located near the fuel pump. Problems with dirt in the fuel line are most likely to occur when you want them least, i.e. in heavy weather as this is when the contents of the tank will be agitated most mixing dirt that would normally not move with the diesel.

If the fuel is clean and the low pressure side has no air then you need to check the high pressure side as there may be air in the line between the injector pump and the injector itself. The only way to do this is to open the nut on the injector half a turn and turn over the engine until the air is purged and diesel is sprayed out. Tighten the nut again as the engine is turning over and this should ensure diesel is delivered to the cylinder. Do the same for the other injector on the other cylinder.

If the engine cannot be started

If there is no time as in most of the situations where you use the engine, for example coming back to the marina/mooring:
Anchor, or pick up a mooring, or set sail if there is wind, or get into a tender to bring a long warp to a pontoon or some strong point to keep it off the danger zone, possible use of boathook, call on VHF a nearby boat/coastguard to request a tow.

Batteries, further information

Best practice when using two batteries as on Obsession is to have "Battery 1" exclusively as a starter battery and "Battery 2" as a services battery.
Battery 1 should be a shallow cycle starter battery (supplies a large current for a short time). On Obsession it is a 100AH marine battery.
Battery 2 should be a deep cycle battery (supplies small currents for long periods, for lights, instruments, VHF etc.). It may be depleted to a very low level before being recharged again by the engine alternator. On Obsession it is a 105AH battery.

5.6 Boat holed - taking in water

First priority is to determine where the water is coming in.
Could put one person working on the bilge pump to get as much water out as possible
Possible alter course e.g. go about, heave to - if that would help stem the flow
If the leak is coming through a skin fitting - then there should be a wooden bung near it - plan is then to remove hoses to get back to pure skin fitting then push in the wooden bung
If leak is some kind of puncture of the hull - the use something to block the hole - this could be a cushion, rubber glove, cloth etc.
If immediate risk of sinking - then put out a mayday on VHF
If a liferaft or tender is available - could start to inflate it of have it ready for launch

5.7 Dismasting

Dismasting is a pretty dramatic event and usually occurs without warning when boat is under stress.

Things to have thought about beforehand

Can you rig a spare aerial in the event the aerial gets broken ?
Bolt cutters should be readily available and its location known to the crew.

[ Contents ]

5.8 Heavy Weather

Make sure you know the weather forecast so as to avoid it in the first place if possible. Prepare appropriate sails (reefs, storm jibs etc.).

7 Equipment Maintenance

All keelboats and the tender should receive maintenance checks three times a year (at the start of the summer season, mid-summer season and at the start of the winter season).

Checks should include:

Read the RNLI Sea Safety booklet: www.rnli.org.uk/what_we_do/sea_and_beach_safety/sea_safety/sea_safety_home and Caring for your lifejacket: www.rnli.org.uk/who_we_are/press_centre/download_centre?selectSection=142348

Ruffian: The Ruffian class safety officer should be invited to check the Ruffian once per year.
