1.1 CertificationApproved under section V regulation 47 Solas 1983 including 1996amendments.

1.2 General description

The craft has been designed and constructed for offshore use in rough water. Itwill provide high-sustained speed in rough offshore environments.

The boat is moulded from fire retardant polyester resin. The space between thehull and liner is filled with polyurethane buoyancy foam, which provide the craftwith enough buoyancy to remain afloat even if holed below the waterline.

Carrying capacity is up to 15 persons including space for stretcher. The boat isself bailing and protected by a closed cell foam fender covered with two layersof heavy duty PVC skin. This design gives excellent shock absorbingcharacteristics with low re-bound. Lifelines and handgrips are fitted around thegunwale.

An approved Off Load single point lifting hook for attaching the fall from a davitor crane is mounted on the centre console. The hook can only be opened whenthere is no load on the fall and must be used together with the painter releasehook on the bow for safe launching of the boat.

In the event that the boat capsizes, it may be righted by two of the crew, one ateach end, climbing onto the fender and pulling sideways.

Fuel is filled on the bow of the boat. Access to the fuel tank is via a hatch on thedeck in front of the console. Draining of the tank and fuel filter is made here.

Loose equipment is placed in a storage locker under deck forward or mounted

in the boat. A bilge pump and a battery -charger are mounted in the centralconsole. Two independently charged batteries are mounted under the aftinspection hatch. When running, the engines will charge the batteries. Whenthe boat is in the stowed position, the charger will take over. The charger is

supplied with 42V ac from the ship via a quick release plug on the starboardside of the central console.

2 LAUNCHING AND RECOVERY PROCEDURES

2.1 Launching the boat

The boat is attached to a lifting cable from a davit or deck crane through asingle point lifting hook mounted on top of the central console. The lifting hookis released manually by stepping on a release pedal on the aft end of theconsole when the boat is fully waterborne.

This applies to boat only, for davit/crane, see davit manual.

To launch boat, proceed as follows:

1 Prepare boat for launch by disconnecting external power supply plug andreleasing lashing arrangement. See fig. 1

Figure 1.

4 Secure painter to painter release hook at the bow with the other end securedto the ship. The position on the ship must be well forward of boat position.The length off the painter to be such that when the boat is on the water witha taut painter line, the boat is directly under the davit/crane. See fig. 3

Figure 3.

Painter release hook.

WARNING!

If the ship is making headway and the painter is not used, this may resultin injury or death to the crew of the rescue boat, and damage toequipment.

5 Lower the boat with its crew until a slack lifting cable indicates you are fullywater borne. The painter now drags the boat.

6 Start the engine. See chap 3.1

7 Remove the safety pin from the lifting hook. See fig.4

WARNING!

Do not put your fot on the release pedal before the boat is fully waterborne.When lowering the boat a sudden stop may cause the lifting wire to behaveelastically witch can effect a slack wire. Stepping on the pedal can then releasethe hook and the boat will fall freely. This may result in injury or death to thecrew and damage to equipment.

9 Engage gear and prepare to drive off. Release the painter by pulling sharplyon the painter release handle mounted on the forward spray hood. See fig.6

WARNING!If the ship is making headway and the painter is released before the liftingcable, this may result in injury or death to the crew of the rescue boat,and damage to equipment.

2.2 Recovery of the boat

Ensure the safety pin is in place and secure radar reflector and mast for markerlight in a horizontal position for protection when hoisted or launched.

To recover boat, proceed as follows:

1 Manoeuvre the boat toward the loose painter end hanging from the ship,2 Attach the painter to the painter release hook. See fig. 3 above

3 Let the boat drift slowly until the painter line is taut. The rescue craft shouldnow be situated directly under the davit or lifting crane.

4 Place the end link of the fall wire into the single point hook on top of theconsole. See fig. 4 above.Make certain hook is in closed position.

5 Turn off the engine.(see chap. 3.5)

6 Hoist the boat just clear of water. Check the lifting hook to make sure it isfully locked and that the safety pin is in place. Please see the instruction

plate mounted on hook.

WARNING!

If the ship is making headway and the painter is not fasten to the boatbefore lifting the boat out of water, this may result in injury or death to thecrew of the rescue boat, and damage to equipment.

7 Hoist the boat aboard and secure it on the cradle. Connect the externalpower supply and refill fueltank. Turn fuel shut off valve on the aft end ofthe fuel tank to closed position. See fig. 2 above.

8 For draining of cooling water when operating the boat in very lowtemperatures, see engine operating manual.

9 Check loose equipment and perform maintenance procedure as describedin chap. 5.

NB! The boat can be recovered with its full complement of crewandpassengers, subject to the davit lifting capacity.

DANGER!

Try to balance the boat if the off horizontal angle, or trim, is considerable

by position the crew equally fore and aft. The risk of injuries tocrewmembers by slipping or falling or to get hit by a falling object isproportional to the trim-angle.

1 Turn main battery switch (13) to ON position by turning clockwise.

2 Fix the dead manswitchon the engine control panel in the run position bypressing a special clip onto the switch. This clip has a lanyard that is to beattached to the drivers clothing. This ensures that the engine will stop ifthe driver is removed from his position.

3 Check that the throttle / gearshift control (16) is in neutral position.

4 Push the start button (12) until engine start, but no longer than 15 seconds

at a time to avoid overheating. When the engine start, release button.

5 If main battery is not able to supply enough power to turn the engine over,transfer battery switch key to emergency battery and turn on. Starting maynow continue with the emergency start battery.


9


10/24

6 If the engine does not start after 2-3 attempts, investigate and rectify theproblem before starting is continued. Repeated starting attempts will onlydeplete batteries and damage the engine.

3.2 Engine operation

When the engine has started, leave the engine running at idle or fast idle for afew seconds to ensure that oil will reach all necessary parts before racing theengine.

When the engine is running, make sure that water is coming out of the exhaustpipe. This indicate the cooling water system is in order.

Check immediately after starting that the oil pressure gauge and the voltmetershow normal values and that all alarms are quiet. If abnormal values are shownor any alarm sounds during operation, the engine should be stoppedimmediately and the cause investigated.

3.3 Flow deflector

The flow deflector mounted to the stator is when lowered into the jet streamdesigned to force the water-trust forward. This enables the boat to reverse anda skilled helmsman can with semi-engaged deflector accurately manoeuvre orposition the boat even in rough water or currents.

ForwardPush control lever forward, away from you. In topmost position the flowdeflector will be out of the jet stream and the boat may accelerate forward.

Reverse

Push control lever backward, towards you. In downmost position the flowdeflector will be inn the jet stream and the boat may accelerate backward.

3.4 Throttle / gear control

To select forward gear move lever out of neutral position by pushing it forwards.

To increase speed, continue to push the lever away from you. When it stopsthe engine is running at maximum forward speed.

To select reverse gear move lever out of neutral position by pushing itbackwards. This will turn the rotation of the impeller and the direction of the flowinto a direction for witch this unit was not designed. Resulting in a very weakreversed thrust with no practical use other than to clear minor blockage at thejet intake.

3.5 Stopping the engines (normal)

Idle engines and shift to neutral. After high speed running, leave engine to cool

down at idle speed for 1 to 2 minutes. Push the stop button until engine stops.

3.6 Stopping the engines (emergency)

In an emergency the engines can be stopped at any speed, in or out of gear.


10


11/24

Push the stop button until engine stops. Engine will also stop if the dead manswitchis removed.

Warning!Activation of the dead man switch at high speed will cause an immediatedeceleration of the craft, therefor all passengers should remain seated at

all times especially when the boat is proceeding with speed.

3.7 Dead man switch

The purpose of the dead man switch is to stop the engine when the operatorleaves his control station either accidentally by falling into the boat or by fallingor being ejected overboard.

The dead man switch consists of a lanyard with clip at both ends. One end issecured to the operator of the boat and the other end is fastened to the deadman switch on the engine instrument panel. If the operator is removed from hisposition the lanyard automatically turns the switch to the off position thusstopping the engines.

It is possible to manually hold the dead man switch out in the run position, thusoperating the boat temporarily without the dead man switch clip.

3.8 Rescue of persons in the water

A person in the water will be drifting due to the effects of wind and sea, thereforit is important for the helmsman to plan any rescue and inform the crew of theplan.

To effectuate a safe and successful rescue bear in mind the following:

Set a course that puts the boat in a position where the person in the water isdrifting towards the boat.

Reduce speed when close to the person in the water. It is better to stop shortthan to overshoot and have to go around again.

When very close to the person let him drift into the side of the boat.

Two crew members should position themselves on the side of the boat onwhich the rescue is to be effected.

When contact is made the crew should grab the person under the arms andtogether pull him up into the boat. If the person is injured he should be placedon the stretcher keeping his head elevated.

CAUTION!The helmsman should pay careful attention to the position of the personin the water.Make sure he is always clear of the jet drive. If in doubt, put engines inneutral position.Never attempt to bring someone into the boat over the stern. Always usethe side of the boat.

3.9 Towing

A principal function of a rescue boat is to tow and marshal liferafts. Two towingbollards are located under the self-righting arch.


11


12/24

CAUTION!During towing, care should be taken not to foul the jet intake with thetowing line.

3.10 Rowing

Should it be required to row the boat, a set of paddles is supplied. These aresecured to the port inside of the boat.

3.11 Loose equipment

Loose equipment according to regulation is supplied. A list of this is enclosed atthe end of this manual. The equipment is stowed inside the equipment lockerunder the forward part of the deck or mounted in the boat. This equipment mustbe periodically checked to verify that it is in serviceable condition, and that it iscomplete.

3.12 Fuel tank

A 110 litres fuel tank is installed below deck level in front of the console. Onlyclean fuel of a grade specified by the engine supplier must be used.

WARNING!Fire and explosion hazard. Fuel leakage from any part of the fuel systemcan be a fire and explosion hazard, which can cause serious bodily injuryor death.

Careful periodic inspection of the entire fuel system is mandatory, particularlyafter storage. All fuel components including fuel tank, fuel lines, primer bulb,

fittings, fuel filters and carburettors should be inspected for leakage,deterioration or corrosion. Any sign of leakage or deterioration necessitatesreplacement before further engine operation.

3.13 Fuel shut off valve

A fuel shut off valve is situated at aft. side of the fuel tank.Turn handleclockwise to close all fuel delivery in situation with fire and explosion hazard orwhile docked. See fig. 6

3.14 Radar reflector and marker lights

A radar reflector is mounted on top of the console. To avoid damage, securethe reflector in the vertical position before recovery and launching of the boat.

Marker lights are mounted on each side (red/green) and on the top (white) ofthe capsize reversal arc. To avoid damage, secure the marker light in thevertical position before recovery and launching of the boat.

MAINTENANCE PROCEDURES

ForewordMaintenance to this craft is extremely important, as the duties it fulfils requirethe boat to be in a state of continuous readiness. In order to keep a record ofcontinuous maintenance, sign the attached log sheet in chapter 8 after eachinspection. Continue on additional sheet when the enclosed log is full.

5.1 Loose equipment

Loose equipment should be periodically checked to ensure equipment isproperly stowed and is in serviceable condition.

See list at the end of the document

Engine

The engine maintenance and checks should be performed in accordance withengine manufacturer instruction manual, although some basic engine checkswill be covered here.

5.2 Fuel / Diesel

Use only diesel of a quality equal to or higher than prescribed in manufacturesmanual. If refilling from a drum, allow drum to stand 3 to 4 days to precipitate

the water and dirt to the bottom. Then use the fuel at the top.A fuel filter and water-separator is installed in the engine compartment. Thismust be drained and filter cleared or changed as required

5.3 Engine oil level

Check the lube oil level before starting. Ensure that the oil level is within themarked field on the dipstick. Refill if necessary on top of the crankcase, makesure not to exeede the maximum mark on the dipstick.

5.4 Cooling system

As soon as the engine has cooled down,the cap may be opened by turn.Check the cooling water level against the lower edge of filler socket in theexpansion tank.Refill tank from the top cap up till the lower edge of fillersocket (B) in the expansion tank.


15


16/24

Raw water cooling

The cooling water is taken from the pressure side of the waterjet.This system prevents possible damaged rubber impellers,which can createhazardious situations.It will also ensure a more conbinous waterflow throughthe engine,especially in choppy seas.

NOTE :Maximum 20 minutes idle speed running in sea when gearbox isdisengaged.Maximum 5 minutes idle speed running in davit.

Waterjet

This unit has been designed to require the absolute minimum of maintenance.However, it is recommended that the unit be dismantled and inspected for thewear on bearings, seals etc, and corrosion annually as a minimum requirement.

Furthermore, to comply with the recommended maintenance, both the log in theend of this manual and the provided manual from the manufacturer, will ensuremaximum utilization of the boat.

5.5 Water seal

Any leakage through the water seal is detected by water flowing directly into thehull from under the bearing housing.

Inspect this area periodically to ensure that the main seal is sound. To inspectseal, see dismantling procedure in manufacturer handbook.

5.6 Drive shaft universals

Every 30 hours sparingly grease the universal joints and sliding splines. Do notover grease.

5.7 Sacrificial anodes

The unit is fitted with zinc anodes for cathodic protection. They will waste away

in sea or contaminated water. (See manufacturers manual for exact anodelocations).

Regularly inspect these anodes andreplace if eroded by more than 50%. Ifallowed to disappear, corrosion will start on the aluminium parts, which couldeventually damage the unit.

NOTE!

The rate at which anodes erode away will vary considerably depending on thenature of the water. Check anodes monthly initially until a safe longer checkinterval can be established from experience
