Cycling to an Aquaduct in Rural France

The weather report looks very promising for winter...some sunshine, high of 3C for the day. Now that is a good reason to take my Dahon folding bike to explore rural France. I had known of an aquaduct in the region from my earlier trips (An aquaduct is an ancient man made structure to tranport water between on hill to the next over the valley). Good old google earth was consulted and the coordinates entered to my Garmin 60Csx GPS. A route from where I am staying at the moment at an olive farm in Rognac was planned. This trip will take me through some villages and the estimated distance with some diversions will be about 45b km. Just about ideal.I had to rely on my GPS for navigation since I do not speak French. Asking for directions in English languiage in France might not be a very good idea. You can end up in Holland! A thick rubber band was used to strap the GPS to my Dahon. I promised myself that I will buy a proper GPS holder in future.If the GPS fails then I will use the road signs which is ok.After cycling about 6 km from Rognac I came across an open air market. I was told sinec it is near Christmas there are quite a lot of these pasar malams all over.These guys werte selling some Spanish made electric bikes at the market. I had a chat with them and they were very interested in my machine. The electric bikes are quite expensive..around 1500 Euro for a basic model.The view along the way is fantastic. Only a person on a bicycle will be able to enjoy such views. There is a small river that flows parallel to the road. There were also farms not too far from the main road but of course the growing will have to wait for better weather.Then from a distance I could see the majestic structure of this ancient aquaduct. By then I had cycled for over an hour. Although it was 3 C, I did not feel cold while cycling but when I stopped I found that I was sweating a little.It is amazingly beautiful. I just cannot imagine the number of (probably slave labour) that was required to build it. And they can think of the arches to support the column.I saw a trek by the side of the aquaduct and wanted to climb up to the top. Being unable to understand French, I had entered a private property and by the time I was 100 meters on the trek, some fierce looking dog that looked like it had not been fed for a week came after after me. Then the owner , a fat lady appeared. I told her using sign language that I wanted to go to the top of the aquaduct but she shoke her head and said "Neil" . I think that was simple enough to understand and I went off.I took off on my bicycle again along the D20 route, hoping to get to a store where I can get some sandwiches for lunch. There was a restaurant along the way but it was a high class one so I skipped that.By now, I had guessed the meaning of "la propriété privée" but I could not resist venturing into this arae to enjoy the nice river. Besides i did not see or smell any dogs.There were no sandwich stores for the next 10 km so when I saw a fruit store I stopped and bought myself a bunch of bananas for a healthy lunch. these few bananas cost me 2.5 euros which is about RM12.00 so it is not cheap. Turning back towards home, I decided to climb up Ventabren which is about 1200 ft high. A pleasant climb with a lot of cold sweat.

At the top after a few kilos of steep climbing.Nice view from the top and I was suprised to find a museum and other tourist attractions around. It is now time to go home as it gets dark by just after 5 Pm. so it was another hour of cycling.

This si the railway station at Rognac which is located in the village centre. It has been a great day and I had enjoyed cycling in the cold 3C weather.

A quick tour of Switzerland

It all started when I casually mentioned that I will be going for a cousre in France and I will be side tracking to Switzerland over my old school's forum. One old scout KC Foong came over with a private email that he can arrange for a hiking trip in Switzerland if I am keen. He has a Malaysian friend staying in Switzerland who is also a keen outdoorman. So I was linked up with a fine gentlemen KB Tan from Johore. Several emails later everything was set and I was ready to go. We were scheduled to meet up at the train station at Yverdon Les Bains on Friday 25 Nov 2010 at 1700 hrs local time. I arranged my flight from Kuala Lumpur to Amsterdam with a connecting flight to Geneva. Upon arrival at Geneva I have about 6 hours to loiter around before taking a train to KB's village. The airport offers a free bus trip down to town but it is valid for only 80 min. So I took along my bike to Geneva town for some sight seeing.Geneva is a nice clean city. Everything seems so organised and neat here! But it is cold.By evening I took a train to Yerdon Les Bains where KB Tan will come and pick me up at 5 pm. From there it is another 15 min drive to KB's house which is in a village. Sorry ..no photos of his house as it was dark by the time we arrived and the next whole day we were out. BUT believe me, it is a very nice old farm house and KB Tan has done a good job renovating it.Next morning by 6 am were were already on the train to Zermatt a popular skiing resort at the base of the famous Matterrhorns.KB is a veteran traveller..always well prepared. He even stocks up sandwiches and drinks for the trip. As this is the winter sports season, there are a lot of tourist in the area. we went away from the crowd as soon as we could.This area is like KB's backyard and he knows the area well . After putting on the snow rackets we started trekking on the snow. For a beginner like me it is very tiring trekking on the snow.Except for a shepherd there was nobody on the trail. One gets a wonderful feeling of loneliness here.The temperature is minus 17 degrees for that day and we decided to head for a church where we can get some shelther so thatwe can have a hot drink.After our tea time we spent another hour coming down. It was an interesting trip for me.It is now time to catch a train to Berne , the capital of Switzerland.It started snowing by the time we arrrive Berne. This is the famous clock tower in Berne. But life goes on like normal. people here are used to snowing..it is just like a light shower but a little bit colder.Even the cheese from this outdoor market is frozen.

From Berne, we took another train to another town Basel where there is a very popular Christmas night market...some sort of pasar malam to me but cleaner and run by Mat Sallehs.

This man was selling puppets and at the same time giving a puppet show. I enjoyed the show but did not buy any puppets. I have a short video and will upload it later.
KB's wife, Melody a Swiss and is also a seasoned traveller, having stayed in India and Malaysia.


Next morning I was up early to take a TGV train to Marseille, France for some more adventure. Thank You KB Tan for hosting me and thank you KC Foong for connecting us! We will meet in Malaysia!

Building a Hull of my Gypsy Catamaran

After the 4 pieces of foam composite panels were constructed it is now time to assemble the pieces together to form one hull. First I have to find some timber to become the base of the bulkheads. Someone was demolishing a wooden house and I bought 4 pieces of 2 by 6 quite cheaply from him.

The spacings for the bulkheads are marked as per the plans. Wooden blocks are placed at the correct stations . Bulheads 4 and 5 were the first to be installed. The bulkheads are built from BS 1088 export quality Meranti marine plywood. A sprit level gauge is used to ensure that the bulkheads are perpendicular.A thread through a hole at the half width waterline of all the bulkheads are used to judge the levels/bulkhead heights. All the figures are given in the plan.I only have to use my physical strength to position the bulkheads. 2 by 1 woods are used to raise the bulkheads. Chipboard backbones are then made to provide some temporary structural strength and later to ensure the hull bottom is flat when it is offered to the hulls.These chipboards are removed when the hull is ready. A lot of "heavy" physical work is involved at thsi stage so I got hold of a local fisherman Yee to assist when he is not at sea.The backbone goes all the way to the transom.The first composite flat panel is then brought in. It need 3 person to put it in position. This is not so much of a weight problem but more of a size proble. Wooden stilts from 2 by 1 wood are used to support the panels. The panel is clammed onto the wood. Final position adjustments of the panel are made.The panel is then secured to the bulheads by screwing the panel into temporary wooden blocks.The second panel is then brought in and the same process is then repeated.
The initial use of F clamps make the job of fine adjustment of the panel position easier.The bow of the hull is then "forced" together using long clamps and twisting wires. At this stage the shape of the hull is formed. I cannot stop admiring the beautiful shape!The bow is glassed in stages so thet the wires can be removed one at a time.Next the bottom panel is positioned at the top of this inverted hull. Heavy objects like bricks and stones are used to ensure a flat bottom and not an "S" shaped bottom!The most difficult part is building the bow and getting the correct shape. A sort of stich and glue method is used. Next will be the fairing and painting of the hull before turning over '

Doing the Helicopter Underwater Escape Training

It is a requirement by the oil companies that all pilots and passengers flying offshore to have a regular Helicopter Underwater Escape Training (HUET). In the early days, the training was conducted overseas (Singapore only lah) but over the last few years we have one training centre in Terengganu..the TSTC (Terengganu Safety Training Centre) so there goes our paid vacation. This course is to enlighten and train pilots and passengers how to escape from a sinking helicopter in the unlikely event of a ditching. If you talk to survivors of these helicopter ditching incident you will realise how undergoing these regular training had saved their lives. ( There had been three ditching incidents in my company so far!)
Normally the training starts at the base itself. Here we get to refresh ourselves on all our emergency packs and actually feel its contents including eating the super high energy glucose. Flares are provided for us to fire. Since I am a sailor as well I take this training very seriously.


After the fireworks we adjourn to the Terengganu Safety Training Centre. Normally we have some ground lectures to update ourselves with the latest procedures etc. For this trip we were introduced to the STASS..Short Time Air Supply system which actually provides us with air for an extra minutes should we go underwater. By then the helicopter simulator is ready.

There are three compulsory exercises to be done in the pool. The exercises are( a)...to escape through a hatch nearest to where you are seated,( b)..Escape through only one available hatch assuming the other exits are blocked and damaged and the most interesting exercise (c) ... is to escape with the helicopter rolled upside down.Exiting is one thing but to exit applying the CORRECT technique is another thing. You will be surprised that many people declare themselves as non swimmers hoping for some discount but normally that is not available!


It is actually quite good fun for me but the inverted exercise normally has a lot of water going into the nose!


We finally spend some time inflating and boarding a dinghy similar to the type that we carry all the time. In the olden days we had an additional exercise ie uprighting a capsized dinghy but nowadays the modern dinghy can be use on either side so there is no requirement for this strenuous exercise.
I am actually paid to do these fun things! So it is a good life after all.

Building Foam Composite Panels for the Hulls

Having gained some experience in the making of the flat panels under the hulls, I come to the most exciting part of the work so far...building COMPOSITE panels for the hulls. Normally when a boat maker wants to build a composite panel vacuum bags will be used. The air is sucked out at a few atmospheric pressure so that the FOAM bonds with the skin. Now, if I am mass producing boats that is the option to use but then I am only going to build one boat so a LOW Tech solution has to be made. Luckily I have bought Richard Woods' plans and he has given instructions for a low tech way of making hull laminates. Reasons why a Foam laminated hull is more superior is that it is light, Very strong, heat insulator and the foam does not burn. Of course it cost much more than solid fibreglass and wood but in the end it is worth the extra cost and work.This year's weather has not been normal....a lot of rain even during this "dry" period so I had to extend my tent workshop and buy extra canvas so that if it rains after I had laid a glass panel it will not be affected.These 16 mm thick melamine boards are the mould for the production of the composite panels. It had to be on a level floor and are joined together with cellotape. The dimensions as per the plans are drawn onto the hulls. Flanges, which are strips of 4 mm melamine wood are placed at the edges of the drawn hull shape. these flanges makes the joining of one panel to the next easier later on.After the shapes and flanges are ready, a layer of gelcoat is applied. It is laid to set for several hours.When the layer of gelcoat has almost cured, a layer of 600/225 biaxial matt is applied. I had requested my friend Robin Tan to come over and give me some hands on training on the making of these panels. Robin has magical hands and he has built several boats including a catamaran (24 ft) . He explained the correct technique of rolling the matts and how to minimise and get rid of air bubbles which are the natural enemies to the panels.These are the PVC Foams that I bought from DIAB Australia. DIAB has a branch in Thailand and I had to deal with the Thailand branch . Now listen very carefully.....if you have to deal with them, be very very careful. My plan calls for Grid Scored foams and my request from DIAB Thailand was Grid Scored Foam.Yes we have ..no problem we can sell..etc and they invoiced and delivered me the Plain Foam. The foam comes in sheets of 7 ft by 4 ft . Quick correspondence with Richard Woods the boat designer suggested the only way that I could use the plain foam is to cut it into 6 inch squares with a hole in the centre and paste the pieces together again so that a good laminate could be achieved. It is a real pain in the **se! What you see here is the amount of foam for one panel.The foams had to be bonded onto the layer of glass using a special paste Divilette 600. The paste is VERY expensive, had to be imported from DIAB Australia and is classified as a dangerous good so the handling charges are a lot! And even though DIAB has a regional office in Thailand, no stocks are kept in Thailand so each user had to individually import the stuff from Australia. It looks like poor business sense but the real reason is that these paste has a life of 90 days if stored at a room temp of less than 25 C. Of the 90 days, 30 days are spent at sea and wharehouse so that leaves me with only a month to work.I did a trial with a few pieces of foam on a small part of the panel and waited for it to cure to see if the method works. Once I established that it works, then the work work of tiling and gluing the foams began. It is a back breaking task and I had to work fast so that the bonding paste do not cure in the pot. Each foam had to be inspected for proper bonding.

After the layer of foam is ready, another layer of 600/225 matt is laid on top the foam. the foam is now "sandwiched" in the middle of the two glass skin. 600 mm strips are placed all around the panel for extra protection.There is only so much of mixing and working that one person can do so in the later panels i had engaged the services of my friend Yee who is a fisherman to help. I imparted whatever knowledge I had on the subject to him and he was of a great help.
The cured panels are then trimmed and stored. a total of 35 man hours is required to produce on of these panels so it took me about 5 weeks of free time to produce the 4 panels for then hulls.
