Engine Maintenance

Engine Maintenance

Beta BD722 20 HP Number K15553.

She has a High Rise exhaust and a siphon break plus an extra fuel line filter.

Beta Marine engines are essentially Kubota diesels & meet all current and projected exhaust emission regulations – the RCD (Recreational Craft Directive 94/25/EC as amended by 2003/44/EC).

Fitted by TS Marine for Ron Pell on 24th June 2005



She was service by TS Marine whilst in Derek Morland's Yachting Sport's yard in July 2011

Did about 190 hours during summer 2011 as we moved her North, round Land's End to Maryport by way of Milford Haven, Holyhead and Douglas!

Serviced today 7th June 2012 by John, Foreman of MPM North West Ltd. I watched and tried to learn!

The service was designed to be a 250 hour service - raw water inlet looked clear and bubbled. John changed all the oil, oil filter, air cleaner, impeller, sacrificial anode and topped up antifreeze coolant. Fan belt changed and adjusted. Two new Additionally sprayed the throttle control with WD40 (need to do panel next time up) and cleaned the oil from the bilge. Engine checked for leaks.

John showed me how to change the oil filter (screwed back on clockwise) and first put s thin film of oil around the rubber gasket and thread to ensure a good seal.

Didn't see how the fuel filter was replaced - it was at the back of the engine and hard to manage. John did in the end but this needs looking at. Luckily only needs doing every 750 hours so should be OK.

Air filter was fitted too tightly and slightly damaged. John replaced anyway. Reasonably easy to get to.

Sea water impeller was fine - no degradation at all - good job as Beta Marine had sent the wrong size impeller. I will get the right one (and a spare fan belt) by post from MPM North West Ltd.

- I need to have a 10mm and a 12 mm screw wrench on board.
- Also a spare oil filter / fan belt / 'o' rings / impeller lubricant and spare impeller.

Beta Marine’s Seagoing engines are:
• Heat Exchanger cooled, indirect injection, naturally aspirated marine diesel engines.
• Multi-cylinder with high inertia flywheel for smooth running.
• Three vortex combustion for quiet running, low emissions and excellent fuel consumption.
• Quiet gear driven camshaft for engine reliability and easy servicing – no timing chains or tooth belts to replace.
• Water cooled exhaust manifold.
• Battery charging alternator 40/65 amps – giving full power at cruising speed with 12 volt starting as standard.
• Heater plugs for cold start below 5°C.
• Output rotation is clockwise in ahead, viewed from gearbox end.
• Technodrive or Newage PRM gearboxes with 2:1 reduction ratio as standard.
• Fuel filter and mechanical fuel lift pump.
• Lubricating oil filter and sump drain pump.



M.O.B.

M.O.B.



Harness Rules for Cryptic

Harnesses should be worn whenever

- Whenever a crew member feels it necessary.

- Whenever the sails are reefed due to the wind strength

- When approaching an area of tidal disturbance

- Whenever a person is alone on deck

- Always after dark

M.O.B.

Many people's first response to someone falling overboard, while the boat is under sail, is to turn on the engine and return under power. This technique can easily cause greater harm to the situation. Lines can get caught around the propeller and the spinning propeller can cause harm to the victim in the water.

Whatever method you choose the old mantra applies: Practice, practice, practice.

The Deep Beam recovery.

Yell “man overboard”.
Throw a PFD or other buoyant objects.
Assign a spotter.
Helmsperson steers to a 'deep beam' reach - about 20 degrees below a beam reach.
The apparent wind should be about 110 degrees off the bow.
Sail for about 2 boat lengths.
Tack into the wind and you will be all set up to return on a close reach.
Sail to windward of the victim.
Cut the sails to stop just windward of the victim.

The Quick Stop recovery.

Yell “man overboard”.
Throw a PFD or other buoyant objects.
Assign a spotter.
Tack the boat into the wind but leave the jib sheet trimmed on its original side.
As the boat tacks trim the main and leave it trimmed.
Keep sailing a circle around the victim always shouting encouragement.
When you are ready with a line to throw head upwind near the victim
Drop sails or approach on a close reach and cut the sails.
Return under power.
Secure lines so they are not dragging in the water
Cut the engine when close to the victim.

Under Power Recovery Technique

Yell “man overboard”.
Throw a PFD or other buoyant objects.
Assign a spotter.
Bring the boat upwind of the victim and broad side to the wind.
Then allow the wind to gently push the boat towards the victim
Adjust position with the engine.
Have crew throw lines to the victim
Be sure to cut the engine once close.


Or ... as the New Zealand Coast Guard would do it ...

WITH AN ENGINE


To stay as close to the person in the water as possible:
1. Come up to wind and tack, leaving headsail cleated so that boat stops hove to.
2. Throw a heaving line to the person in the water, if in range and haul alongide.
3. If not within heaving line range:
- start the engine
- lower or furl the headsail
- sheet the main sail amidships.
Ensure there are no lines or sheets lying loose that could foul the propeller.
4. Motor to leeway of the person in the water and approach him/her head to wind.

WITHOUT AN ENGINE


A simple way to recovery is to:
1. Put boat into an "apparent" beam reach (burgee across the boat). Allow yourself some sea room to maneuver and get yourself organized to recover the person from the water.
2. Tack and sail on the opposite beam reach (person in water now on weather bow).
3. Approach on a close reach easing the sheets in the final stages. Leeway will increase as you slow down - allow for this.
4. In a larger boat it is easier to come alongside to windward of the person in the water and make the recovery over the leeward side.
5. In a dinghy, come alongside to the leeward of the person in the water and make the recovery by he weather shroud.

Is A Third Reef Necessary?

For Cryptic this season (2012) I have had a fully battened mainsail put on a new ZSpar mast and boom. Its been hard work putting up the mainsail and getting the reefs sorted. I thought I had it straight away - two (first and third) on the port clutches and the second on the inside starboard clutch. Turns out this is correct but the one I assumed was the first reef was actually the third (it is the first if you count up the mast!).

I am a bit clearer now but fitting the foot of the reef rings around the 'rams-head' is hard work - especially as you have to go on deck to do this. I need to remember to keep all the reef sheets running free too ... especially as when hauling up the main halliard.

Do I think I need three? I am not sure. The boat soared up the Sound of Mull (less than four hours!) under mainsail only, when the second reef was in ... in about 20 knots of wind.

Still, early days.

Below is an article I found of interest and am re-publishing it again here. I have changed nothing and all the work is John Vigor's - see http://www.johnvigor.com/Welcome.html

http://johnvigor.blogspot.co.uk/2011/01/is-third-reef-necessary.htmlJanuary 27, 2011

Is a third reef necessary?

EVERY NOW AND THEN some cruising sailor gets caught out in a gale and comes home wondering out loud if the mainsail should have a third reef. The advice comes pouring in from all sides, and it’s usually contradictory and confusing.

Racing skippers will tell you they never reef. Well, hardly ever. But it’s different for them. They don’t care if their mainsails flog themselves to bits on the beat. They’re going to buy new sails next season anyhow. And they’ve got large muscular crews with highly developed clinging powers, so they won’t fall overboard when the boat broaches and the mast hits the water.

Some sailmakers aren’t much use, either. A contributor to one bulletin board I read recently said his sailmaker simply refused to put a third reef in the mainsail for his 26-foot full-keeler. “He said the extra sailcloth and grommets involved would screw up my main's light-air performance. I would add too much ‘stuff’ (weight, hardware, etc.) up high, where I don't want it. And would not let the leech open up properly in light air.” Well, to put it delicately, this is pure poppycock, of course. That sailmaker has been brain-washed by racing skippers.

However, I personally don’t believe a boat of average displacement under 35 feet in length is going to benefit from a third reef in storm conditions in the open ocean. Perhaps that reef might help in calm water near shore, but it’s not going to generate enough power to push a boat to windward in the big seas a storm generates.

My preference is for two oversized reefs on a boat of that size, and when things become too hectic for the second reef you have three choices: lie a-hull, heave to under a main trysail, or run off, either under a storm jib or under bare poles.

Now when it comes to bigger boats, a third reef can make sense. The difference here is that a big boat not only finds it easier to carry its way against big waves, but it also can carry comparatively more sail to drive it to windward. That’s because stability (hence the power to carry sail) increases as a cube of the boat’s length, while the force of the wind increases only as a square of its speed.

So, while a 40-footer is only 62 percent longer than a 25-footer, it can carry 410 percent more sail for the same degree of stability. That means a third reef in a 40-footer is comparatively much bigger than a third reef in a 25-footer, and is thus able to generate a comparatively greater amount of power.

I once had a third reef added to my main on a 31-foot heavy displacement sloop. I went through seven gales with that boat and never used my third reef once. I thought it would substitute for a main trysail, but by the time the third reef was down, the center of effort had moved too far forward. The heavy wind against the mast and rigging simply blew the bows off and she wouldn’t heave to. That’s what a trysail is all about. It gets sail area well aft, so the stern will blow to leeward and the boat will end up lying pointing at an angle of 60 or 70 degrees off the oncoming wind and waves. That’s the safest, most comfortable position until the boat starts to be picked up bodily and hurled down sideways.

Finally, let me repeat the three basic rules of thumb about the timing of reefing:
1. Reef before you have to.
2. When sailing downwind, reef in the same wind speed you would if you were beating. (Not easy either to judge or to do, but very necessary.)
3. When in doubt, go straight to the double reef.

Today’s Thought
The tempest’s howl, it soothes my soul,
My griefs it seems to join;
The leafless trees my fancy please,
Their fate resembles mine.
— Burns, Winter: A Dirge

Boaters’ Rules of Thumb, #152
WHEN to reef? Before you lose control. On the wind, the signs are pretty obvious: sidedecks awash, dreadful weather helm, and lack of response to the helm. Downwind, watch for prolonged surfing and a sloppy, dead feeling to the helm when a waves passes underneath the stern. Time to slow down.

“Okay.”

our Van de stadt 34 had three reefs,and hove to perfectly for 48 hours in a mid Atlantic gale, was also useful sheeted right in hard as a steadying sail with twin headsails going down win, would stop the rolling.

Your experience with a Nic 31 probably says more about the boat than the sails - having tried both types I'm convinced that medium to light displacement and traditional hull from i.e narrow transom is the best all round cruising boat. i'm sure others will disagree

John Vigor said...

Hi Bursledon B:

Yes, I would agree with you that moderation in all respects is the way to go with a cruising boat. The extremes of very light displacement and very heavy displacement often have more cons than pros. And Van de Stadt knew what he was doing when he designed the 34. Very nice boat.
Have to say, though, that I'm always astonished when people in foreign countries reveal what they know about me. It wasn't actually a Nicholson 31 that I owned, but it was a very close relative, a Performance 31 designed by Angelo Lavranos.

Cheers,

My 26 footer ended up with 4 reefs (long story), One to many, but I used the 4th reef alot around Wellington, across the Tasman and then around Tassie. (3.5 hp outboard so really needed to sail in strong winds).

I delivered a 28 footer back to NZ with only two deep reefs... couldn't get the groove right, either too much sail or not enough, really wished I had three moderate reefs.

Saying that neither boat had roller reefing headsails so I used the main as my throttle. I reef and unreef often, sometimes a couple of times per watch to keep in that nice comfey groove just below hull speed were the windvane works best.

Give me three reefs on any sized sloop or cutter designed for offshore.

I enjoy your writing John, and love the black box theory, I apply it alot in real life, it's probably saved me a few times..

Cheers

Hi Ben:

Yes, most of us are inclined not to fine-tune the exact amount of reef, as you do with such dedication. Most of us are content to be a bit underpowered and get nowhere fast. But you're absolutely right about the need for a good amount of sail area in strong winds, especially in the tough seas you seem to be sailing in, between OZ and NZ. Your frequent reefing and unreefing is certainly earning you points in the black box.

Cheers and best wishes,

s/v Windward said...

Windward, my Herreshoff 26 (OK, it's a Chrysler, perhaps the Rodney Dangerfield of sailboats, but Halsey was the hired gun and she sails very, very well) has three fairly deep reef points, each reducing the 26 ft luff by 4 ft.

On my local mountain lake I'm able to use the 3rd reef a couple of times each winter, when winds are 20-25 kt or more. I don't have pretenses to sailing offshore, but do sail on North Carolina's Pamlico Sound, and up to 25 miles offshore (but inside the gulf stream) from Ocracoke to Cape Fear. I was thankful for the 3rd reef a couple of years ago on Pamlico Sound during several days of small craft advisories, making 5.4 to 5.8 kt upwind using that and about 40 sq ft of headsail. The waves were only 4-6 feet despite the 25-30 kt breeze, so there was no problem getting enough clear air to move the boat. Downwind that sail combination kept me above hull speed most of the time, and I could not have carried more sail safely.

Sailing 20-25 miles offshore south of Cape Lookout, I have found it challenging to keep the boat moving when heavily reefed, and have had to carry more sail than I anticipated. I've had the luxury (good fortune? good sense?) of avoiding gale conditions there, so don't yet know whether the third reef would be effective for me then.

Some Hand signals used by scuba divers

Some Hand signals used by scuba divers .... usually used underwater!

I am cold! Hugging chest - Crossed arms in front of chest, upper arms grabbed by opposite hands.

I am out of breath! Hands indicate rising and falling chest.

I can't clear this ear: Pointing at the ear with forefinger.

Go that way: Fist with one hand, thumb extended and pointing in the direction indicated.

Go under, over or around: With palm down, hand motion used to indicate intended route to go under, over or around an obstacle.

Ascend, or I am going up: A fist is made with one hand, thumb extended upward, and hand is moved upward to emphasize direction of travel.

Descend, or I am going down: A fist is made with one hand, thumb extended downward, and hand is moved downward to emphasize direction of travel.

Something is wrong: An open hand with palm down and fingers apart is rocked back and forth on the axis of the forearm.

Are you OK? or I am OK! A circle is made with thumb and forefinger, extending the remaining fingers if possible. (The OK sign may be also be made without extending the fingers if wearing gloves).

Stop! Hand raised vertically with fingers together and palm facing the receiver.

Turn around: A forefinger extended vertically and rotated in a circular motion.

Which direction? A fist is make with one hand with extemded thumb and the hand rotated on the axis of the forearm through 180° a few times to ask which way to go.

Boat: Hands cupped together.

Buddy reference. Used alone: Get with your buddy: Fists made with both hands, forefingers extended, and hands placed together with forefingers parallel and in contact.

Hold on to each other - Maintain physical contact: Both hands clasped together.

Who will lead, who will follow: One hand pointed at the diver who will lead then positioned in front of the body, pointing forward, then other hand pointed to the diver who will follow and positioned behind the first, direction indicated with forefingers.

Level off at this depth: Flat hand with palm down and fingers spread moved slowly back and forth horizontally.

Take it easy, Relax or Slow down: Flat hand with palm down moved slowly up and down a few times.

Give me air now (emergency implied): pointing to the mouth with thumb and fingers together, moving hand back and forth a short distance.

I'm out of air: "Cutting" or "chopping" throat with a flat hand!

I don't know: Shrugging shoulders, arms bent, hands to each side, palms up

Danger in that direction: Clenched fist pushed/pointed in the direction of the perceived hazard.

How much air do you have left?: One hand held flat, palm up, while index and middle finger of the other hand are placed on the palm.

There is air leaking from your equipment: Index finger is brought down to thumb in repetitive motion. Size of movement indicates severity of leak.

Cut the line: A request to another diver to cut a line or net. Often used in case of entanglement where the diver making the signal can not reach the point where the line should be cut.

Safety stop: Signal is used to indicate that the diver intends to do a safety stop at that point.

Line, Line tangle or Cutting the line: The index finger is crossed with the middle finger to indicate line. If the hand is moved in a figure 8 it means a line tangle. Pointed down and rotated means a line tie off. In combination with the cutting signal it means cut the line.

Silt, or Silting: Palm and fingers down, thumb rubbed against the tips of the fingers

I have a cramp: Repeatedly clenching and un-clenching fist, and point at cramped area

I am on reserve or I am on bailout gas or I am low on gas: Clenched fist held steady, about level with head or chest, palm side usually forward

Time up - time to turn the dive and start heading back: Flat hand held roughly horizontal with tips of other flat hand's fingers touching the palm at right angles

Come and get me as soon as you can, but not an emergency: Signal to boat. Arm held straight up at the surface.

I see a hammerhead shark: Both fists against sides of head.

I see a lobster: Fist with index and middle finger pointed out horizontally and alternately waggling up and down.

I see an octopus: Back of hand or wrist covering mouth, all fingers pointing outward from mouth and wiggling.

I see a shark: Hand flat, fingers vertical, thumb against forehead or chest.

Using A Marine Radio

The accepted conventions for use of marine radio are collectively termed "proper operating procedure."

These conventions include:
o Listening for 2 minutes before transmitting
o Using Channel 16 only to establish communication (if necessary) and then switch to a different channel, using a set of international "calling" procedures such as the "Mayday" distress call, the "Pan-pan" urgency call and "Securité" navigational hazard call.

o Using "pro-words" based on the English language –
o Acknowledge,
o All after,
o All before,
o All stations,
o Confirm,
o Correct,
o Correction,
o In figures,
o In letters,
o Over,
o Out,
o Radio check,
o Read back,
o Received,
o Repeat,
o Say again,
o Spell,
o Standby,
o Station calling,
o This is,
o Wait,
o Word after,
o Word before,
o Wrong
o Using the NATO phonetic alphabet: (see later)
o Using a phonetic numbering system based on English


VHF Marine Radios: VHF marine radios are a great asset to all who use them. They are not chat lines however, and should be used for working messages only. Misuse of the equipment could disrupt other users within the area. All VHF radio users are legally required to hold an operators licence and he vessel to which the radio is fitted must have a ship radio licence. A 'station' is a term for a VHF Radio. As a general rule listen to the channel for 30 seconds before transmitting to ensure it is not already in use.

The Radio: All marine radio equipment must be approved according to government specifications. There is a maximum power output of 25W although 1W is usually sufficient for most activities other than distress calls or public correspondence.

Channel Purpose:
• 16 International Distress, safety and calling
• 6 Primary Inter ship
• 8, 72, 77 Inter ship
• 12, 14 Port Operations
• 67 Small Craft safety
• M, M2 Marina Special Licence
• 2, 24, 26, 28 Ship to shore (public correspondence)
• 6, 67, 73 Search And Rescue Co-ordination

VHF Signals: The range of VHF is line of sight and has an Inter-ship range of 15-25 miles. Ship to shore range is about 30-50 miles.
Dual Watch (D/W): a facility that allows you to monitor two channels via switching. Do not transmit on dual watch.

Digital Selective Calling: uses CRS but requires an additional kit for the radio set.

Capture Effect: when a receiver within range of two stations will receive only the more powerful or closer signal, the other signal will be lost.

Aerials - should be high and upright and clear of other aerials by at least 1M. An emergency aerial should also be carried.

Control of Communication
o Ship to shore - coast radio station
o Inter-ship - station calling
o Search and Rescue - Vessel in distress, relay station, Coastguard, on scene vessel / aircraft

Duration of Calls
o Test Call / Radio Check - 10 sec
o Calling on Channel 16 - 1 min
o Calling again on Channel 16 - 3 min
o Listen on channel before calling - 30 sec

Distress calls: Coastguard use GMT all year round. Each station has an obligation to respond to a distress call: write down time, name, position, nature of distress, no of people on board and additional information.

If the Coastguard says 'wait' this means they will respond within 10 minutes.

Any longer than that should be given a reason prior. Only repeat things three times if it is a distress call.

Otherwise use their name once and your name twice. Distress calls should make the following 7 points in order:

o Distress call
o Identity
o Position (Note that the position is given in geographical area as distance 'from object' not 'to object' when working out bearing. Otherwise use Lat. and Long.)
o Nature of distress
o Information for search and rescue
o Invitation to reply
o Message Meaning
o Mayday (Distress)

Definition: When a vessel or person is in grave and imminent danger and requires immediate assistance - fire, accident damage, lee shore situation (under lee shore is when you are sheltered by the shore), diver not surfaced, man lost overboard, person is gravely ill.

Example:

MAYDAY CRYPTIC,

My position is: 180 degrees, one mile from buoy number 1.

I am sinking and require immediate assistance

Four crew members on board, all safety equipment and

EPIRB at 406 MHz


Mayday Relay: Mayday relays are transmitted when the station in distress cannot itself transmit a distress signal or when, although not in a position to assist a distress message is heard that has not been acknowledged. Example:

MAYDAY RELAY, MAYDAY RELAY, MAYDAY RELAY.

This is Yacht CRYPTIC, Yacht CRYPTIC, Yacht CRYPTIC,

MAYDAY Evelyn Rose.

Position is: 180 degrees, one mile from buoy number 1.

Yacht sinking and requires immediate assistance

Four crew members on board, all safety equipment and
EPIRB at 406 MHz


Pan Pan: When a station has a very urgent message to transmit concerning safety of a ship, aircraft or person.

Example:

PAN PAN, PAN PAN, PAN PAN

Hello all stations, Hello all stations, Hello all stations

This is Yacht CRYPTIC, Yacht CRYPTIC, Yacht CRYPTIC,

My position is: 180 degrees, one mile from buoy number 1.

NAME OF SHIP....................... CALL SIGN...................................


DISTRESS TRANSMITTING PROCEDURES
(For use only when Immediate Assistance required)

1.Ensure transmitter is switched to 156.8MHz.

2. If possible transmit two tone Alarm Signal for 1/2 to 1 minute.

3. Then say:
