Alternative solutions to replace a broken belt when not having a replacement

Alternative solutions to replace a broken belt when not having a replacement

As declared earlier we experienced the less nice wake up call of not having a specific belt in our spare part storage. In our case it was the belt to the sea water pump that broke and by some reason we did not ave that specific belt in our otherwise pretty comprehensive storage of spare belts.

When this specific occasion happened we was in the central Med. about one day from south Sardinia and less than two to western Sicily with little wind and pretty high old sea making live less comfortable. Ann-Sofie came up with the idea that we might be able to use thin rope to connect the pump wheel with the engine one. After checking with house Bible for Diesel Engine by Nigel Calder we found support for her idea.

As part of the not specific spare parts on board we have 4 mm Dynema Leech line. That was to be the chosen line for our experiment as to replace the belt. We measured the minimum length and added some length to be able to connect the ends to each other. After connecting three lines we found that measuring the line was the easy part get the same length when fastened was another thing.

We tightened the pump with the lines attached and then we started to engine to check functionality. It worked perfectly!

After running for 10 minutes we stopped the engine and checked the stretch of the lines and as suspected it need additional stretch adjustment and then we started the engine again. For the first 24 hours we checked the engine every 10-15 minutes to make sure it worked and that water was coming out at the goose neck vacuum valve.

We used this solution for over 120 engine hours before we found a replacement belt. After half the number of hours we replaced the three lines with new ones, after inspection the old ones would most likely had coped with many more hours but it felt good to the change.

Conclusion of this experience is that carrying spare leech line 4 mm Dynema could be used to more than originally though. The stretch in Dynema is enough to handle the load when the engine starts and it is strong enough to survive many hours of mistreatment in a warm environment both from load as well as from heat generated by friction as well as heat from the engine.

We exercised our ideas on our Volvo TMD 22 Diesel engine but this could be a solution for the majority of engines on the market and it should work with the V-shaped wheel design also however the stretch has to be checked more often due to possible load. V-Shaped wheels are usually used for alternators which puts on a load on the belt/replacement when it starts to charge. That’s also why some stretch in the line is important so the initial load does not break the lines.

Good news – Dolphins are back in the Med.

 

Sailing outside Algarve, in the Gibraltar Straights and east of Gibraltar along Costa del Sol is offering numerous opportunities to enjoy Dolphins playing around your boat. It is always a joy to see them play, you feel instantly better with their company.

The further in to the Med. the fewer you usually see. This year we had another experience, we spotted Dolphins over the total length of our sail to the Ionian sea and back which made us happy both for the company they offered but more that it meant that the amount of small fish has increased enough to provide enough food for them to be able to live in the Med.

We also got the feeling that we saw more fish when we were snorkelling both in Greece, Sicily and Sardinia. We hope that this is a trend that the fish is coming back to the Med. and that fishing will continue to be limited until a stable volume been created.

2017 – The return sail to Greece with a lot of strange weather and other experiences

 

We discussed during May that a return trip to Greece from Algarve was something that was possible and could be done just for the fun of it. We have done the tour before and had some knowledge what was laying ahead of us. Downside for us was the fact that we where leaving around Midsummer (late June) which put us close to high season and the period of less wind in the Med.

The shakedown cruise was to Gibraltar where we stayed a couple of days as both of us are enjoying Gibraltar but also to choose a weather window for or next leg destined to Sicily and Licata on the south side. Its roughly a week’s sailing and we thought the weather window for the week to come was reasonably good with aft winds and speed. Leaving Gibraltar and sailing into the Med. is magic, the feeling of all the cruising ground laying ahead of you together with crystal clear water and good anchoring was shearing us up.

But the first sign that the weather was turning things upside down for us started a day out from Gibraltar when our westerly wind increased with 10 to 15 Kn (giving 30+ wind in average) more than the forecast predicted but was still manageable but the wave situation increased to 4.5 to 5.5 m high waves coming pretty close to each other and breaking – they were looking pretty mean! Well, to quote Ann-Sofie, do we have a convenient stop around so we could get rid of this very uncomfortable sailing but as we all know no bus stops at sea.

These conditions kept on for two days and we broke our speed record without realising it, new record is 16.9 kn through water.

Almost as worse is when the wind all of a sudden quits but you still experience the state of the sea, this took less than an hour and putting on the engine to make life more comfortable was an easy decision. We started but I shut it down almost direct because there was a strange sound that did not belong there. Opening the hatch to the engine room showed the hunch was right, we were met by a cloud of black smoke that smelled like burnt rubber. After a quick look the diagnose was clear, the belt to our sea water pump on the main engine was broken and the I was unable to move the wheels at the sea water pump. Well, that is no problem we have a newly renovated pump and a big storage of belts in the boat. To change the pump showed that the crack of the belt origins from the pump being stuck. To change the sea water pump on our Volvo Penta is an easy task so after the old one was removed the new one was put in place the search for the correct belt started. We have a lot of spare belts but by some reason that particular belt was not present on board, most likely in one of the many boxes in our apartment.

Finding our self in a pretty rolling environment the motivation to get the sea water pump working was high. Ann-Sofie brought up the idea that we could use thin rope to replace the belt. After a fast check in the Nigel Calder Diesel Engines book we decided to test the idea. We took 4 mm Dynema line, cut it in the right length and put three ropes to replace the belt, tightened the solution and started the engine. It worked!! For the first 24 hours we checked it every 10-15 minutes but after a while confidence grow and at the end the solution was used for over 120 engine hours before we got a new belt. See http://www.sailinglife.se for Ann-Sofies story and pictures.

For safety we changed our plans and decided to go to south Sardinia to anchor and then decide if we should go to Cagliari or not for a new belt. After 24 hours rest we decided to go to Sicily and Licata. Wind where very light and engine was used more or less all the way. We tried to get a new belt in Licata, but sadly we failed. After a short but lovely stop in Licata we went directly to Argostoli, Kefalonia, Greece.

Light winds and clear sky felt like descent conditions however close to the south east corner of Sicily we were stopped (totally black and +1 m waves) and two guys from Guardia Finaza come on board to check that we did not have any immigrants on board which we did’nt. After we showed our intended course for the Finzaza guys, to Greece they warned us that there were a lot of immigrant boats around and we should be very alert and if seen not stop to help for our own safety but communicated with the Italian authorities. During the nigh another two of the high speed boats checked us out which felt good and the trip to Argostoly went without any problems.

Coming back to Greece felt more than good, we missed the Greek cruising grounds a lot. For this cruise we limited our sailing area to the Ionian Sea. Being there in July and August is being exposed to more than one charter boat and a lot of other boats, crowded it was. But, it is a lovely cruising ground with short distances between anchorages and a lot to choose from.

Sailing in the Ionian Sea is using the wind that usually blows a few hours every afternoon so to some extent we sailed a little but motoring a lot. As we all know the north east part of the Med. countries had very warm weather for a month in a row which opened for the weather to actually play havoc with everyone.

For us it meant starting to plan our cruising after the Cape index instead of wind direction and speed. Lightning is not uncommon in the Ionian but this year the intensity was impressive.

Due to this and the reports we heard from Sicily, Sardinia and the Baleares of weather that had been tougher with lightning, higher wind speeds etc we decided to go back west earlier than planned. The basic plan for the return sail was to visit new places we had not been to and not to stress. Well, with history in place we sailed in two day passages between lightning storms and strange weather totally planning our sail to go where the Cape index was as low as possible. Except from our passage from Sicily to South of Sardinia we managed to avoid the lightning storms with margin. Going to Sardinia we were followed by a huge lightning front originated from the north of Africa and we missed it by less than 10 Nm. It kept us on our toes for 5 hours sailing and motoring keeping up a boat speed over 9 kn. We do not like lightning at sea!!

The rest of the trip to Gibraltar was in two day legs to avoid upcoming bad weather that will put us in a standby situation for a week or so. Sailing during this period was not very present but motor sailing was to keep the speed to at least 5 kn. After Gibraltar the Cape index all of a sudden decided to not be a problem and we sailed for half the distance to Rio Formosa in Algarve.

Conclusions regarding the weather was that we used the engine for approximately 500 hours and sailed in less than 120 hours during our 3500 Nm for this cruise. The warm water in the north part of the Med. supported the strange weather situation and we have got many reports of serious lightning storms both in Sardinia, Sicily and on the Baleares during this period of the summer.

The weather was stabilising the further west we come and once passed Gibraltar it was more normal. This profile has kept until now with in-stability in the eastern and central part of the Med. and more stable weather in the west. One reason to the more stable weather in the western part might be that the water temperature has been lower this year than earlier.

Sailing in the Med. is still a wonderful cruising environment. The clear water, usually not to long legs between marinas and anchorages, stable weather and availability to supermarkets in various forms makes life enjoyable. We do miss that we did not sail in the Agean sea this time.

Did we have more failures on this cruise, yes the clutch on our autopilot linear drive broke and had to be changed, and one stainless steel shackle broke but was easily changed.

Good things to have as spare parts are among other things a sea water pump for your engine, spare linear drive or at least spare clutch, an assortment of stainless steel shackles and the right belts.

Snatch blocks

Onboard Lady Annila we have a lot of different blocks. All except three has their given place. The other three are snatch blocks


The two to the left is Lewmar size 2. Big and heavy. But we know that we can rely on them everytime we use them. The specifications as below. One in Lb/in and one in kg/cm.


We use them when we sail with the genacker to guide the sheet into the cockpit and winsch and we use them when hoisting a person up in the mast. 

The small one to the right is a Wichard soft block with very low friction. We have two of them. One is permanently in the top of the main mast replacing the standard block to the genus hailyard. Making less shafe and leave more space up there. We mounted it in dec 2013 and have made two Atlantic crossing plus a lot of other sailing with it.

The other one we have attached to a line that we use on the gennacker sheet change the angel on the sheet to get better controll over the sail when sailing downwinds. The weight of the block is only 82 grams but with a working load on 2000 kg. 

We have not been sponsored by neither Lewmar nor Wichard. This is just our own opponions on these gadgets.

Here we are sailing with gennacker and missen stay sail. With both sheets on the cockpit winsches. The thick white is the genoa sheet, not in use at the moment, and the thinn one with black stripes is the Mizzen Stay sail. And the white using the Lewmar Snatch block is the Gennacker sheet. The fourth block in the background is for the main boom preventer.

Insights part II

 

Owning an Amel Super Maramu is owning the privilege of learning new things almost every day. To summarise is far to boring for the reader so I decided to cherry picking some interesting experiences.

On most SM you have a Goose neck that handles the vacuum being created on the exhaust side of the engine. Sea water is gently coming out when the engine is running and when it’s turned off you could hear the air being sucked in through the goose neck. Over the years the amount of water coming out this way is increasing and when it’s really bad it splashes out in the area where the water evacuation pipes are in the aft of the hatch to the engine room. Making it very wet even in the aft part of the cockpit.

A normal view of this is the vacuum connection/goose neck is malfunctioning in some way. Sorry to say this is not the case if you are running a Volvo Penta TMD 22 engine. The reason for the increase of seawater through the goose neck is that the thin pipes inside the exhaust pipe/exhaust elbow that is mounted on the turbo are clogged preventing cooling water to cool down the pipe.

Most of us are aware that we are not over using the Turbo on the engine which should be used regularly to prevent carbon to clog the Turbo and the exhaust pipe but are we… Well, we have been less good at running at higher revs so the exhaust pipe was clogged and the Turbo had a fair amount of carbon just outside the fan.

The operation to change the exhaust pipe is an easy dismounting excersice but be care full when cleaning the Turbo, it is very easy to damage the fan blades.

After cleaning the Turbo and changing the exhaust pipe the engine was running as new and the water through the goose neck was coming in a normal amount.

Checking the exhaust pipe is not on the normal checklist but will be in the future at least once every second year.

Is this applicable to other engine types like the Volvo Penta TAMD 22 and the 100 HP Yanmar, do not know for sure but a recommendation is to keep an eye on the amount of water coming out of the goose neck and if it increases the exhaust pipe might be the problem.

Most of the Amel Super Maramus are carrying an Onan diesel generator that is supplied with a sea water pump. The sea water pump is mounted with a shaft going into the main engine body. When the lip seal starts to get worn out water might be transported to the engine body and compromise the engine oil with the consequence that it change colour to grey and it fills up the oil sump.

The quality of the sea water pump seals and bearing are good but need an update occasionally to prevent this type of action. Onan offers an upgrade kit that includes all vital parts for this upgrade.

The signs to look for is when you see small drips of water coming out from the seawater pump body, its normally identified through small traces of salt crystals in the open parts of the shaft body.

The seal is a special seal that is not easy to find on the open market so a recommendation is to have this repair kit or a spare seawater pump to handle this type of happening.

We are on the road again or should I say we are sailing again!

We are on the road again or should I say we are sailing again!

After seven months in a Marina you are really looking forward to go sailing again. This time we left the marina with the strategy that the first leg should be an easy one and so it did. Leaving the marina is not hard to do but leaving your friends are worse.

When we left with our friends gathered to say good by, the big hugs and waving us good bye when we left our mooring, sounded our horn in response and slowly moved out from the marina. We miss you already guys!

Out side the marina the state of the sea was calm and no wind so we decided to motor the 25 Nm to our first anchorage of the year. The lack of wind was no surprise and we used the time to fill up the water tank with our water maker that has been in sleeping mood for the last seven months. Happily it worked perfect and the tank was almost filled when we reached our chosen anchorage.

The happiness to spend our first night on anchor was hard to camouflage, when properly anchored we sat in the cockpit, enjoyed the sun set and a small Dry Martini. After this session we fired up the Gas BBQ and grilled home made burgers of decent size and just relaxed. The fact that the boat rolled again after seven moths of total still experience was only positive and pretty soon we realised that the air of the sea had taken its toll, we went to an early sleep.

Early next morning I woke up after recognising an engine sound to close to the boat and went up. A fisherman was circulating our boat and tried to get our attention. He was convinced that our chain was put of´over his net so within 10 minutes we had re-anchored and the fisherman was happy because we had not anchored over his net. After a slow breakfast we lifted the anchor for what we thought will be a short 50 Nm sail. The gennacker was hoisted after an hour on motor together with the mizzen and of we took.

The conditions could not be better and we logged between 7 and 10 knots for the first hours and far earlier than expected we passed our first choice of anchorage, Mazzaro del Vallo and decided to anchor out side Marsala instead but due to increasing speed, we where doing between 9 to 11 knots, we decided that Trapani will be our final destination. After been securely anchored we found that despite a slow start we have had an average speed of 7.8 knots doing only just nothing letting the autopilot steer and enjoying the sail from the cockpit. This is what dreams are built up from!

A good start of the 2016 season has been the case and we will do our best to continue on this track!!

Winter in a marina

What do we do during the winter, are we developing into cave personalities or social participants?

Many persons not living on a boat asks this question, how do you stand to live in such a limited environment over such a long time?

The answer is that one common denominator that cruisers experience is that their social life and diversity has broadened a lot since they went cruising. Especially during the winter/hurricane season cruisers are gathered in marinas for a period of four months or more and most of them are open people and easy to spend time with.

During a long stay like this a social program develops including music lessons, Pilates, experience sharing, joint BBQs, different types of excursions to learn more about the region you are visiting. In all it brings people together and you meet people from many different countries around the world and some times the language is a barrier but you usually find a common language to use if English is not the choice.

Also very nice is when the cruisers starts and supports the radio nets on VHF to distribute general information between the cruisers. These radio nets are very common in the Caribbean and less common in the Mediterranean. Regardless they serve as an important source of information for the cruisers.

Usually a weekly program is published for the cruisers where time and place is announced and if you are not found of or have to focus on boat maintenance you have no problems spending time together with other cruisers on this and that.

So cruising is a very social life and you meet many new persons that over time develops in to dear friends in a way that the shore life seldom do. We have developed many new relationships and more than a hand full of new friends that we will have contact with over time spread over the world. Mail, Skype and blogs are from this perspective nice tools to use.
