I have a so42ds from 2011 (3 cabins). At some point in the future I hope to make a longer trip. The diesel tank I now have is 130 liters which I find inadequate. Has anyone in this great forum put in any extra diesel tank?

Hello Olof, A couple of possibilities you may like to consider. a. If water is not a problem (perhaps with the addition of a water maker) the water tank under the aft port side bunk could be swapped out for a similar sized diesel tank, doubling fuel capacity. b. The space under the floor above the keel and two back from the bilge pump is ideal for an appropriately sized plastimo tank. c. Copy what Xlnt has done in this forum thread from 2013. check this out and particularly Xints photos. They are excellent and this is my favourite solution and in my view very well done by our friend from Norway. jeanneau.proboards.com/thread/2926/so42ds-similar-adding-capacity-siphonI hope this helps as a start. Regards, Trevor

Wow!
Thank you very much. This was very instructive. I like XIts solution. Now I have something to think about.
Thanks Trevor

Dear Olaf, same boat, same problem. I tried several times to solve but... difficult. one solution is to change the original tank with one build in inox, modifying the position of the battery charger and with this you could gain almost 40 lt (they told me 60, but is hard to believe). This solution it costs about 1200€ Second is to take out 5he water tank in the AFT cabin and build there a new diesel tank, but you have to use the aft water access to fill it and an electric pump to move from 9ne tank to the second one or to build a new diesel line to the engine.
any different solution will need a second hole to fill in the new tank and an electric pump to transfer the diesel OR a system to choose which tank you want to use but be aware that when you will be out of fuel from one tank, switch to the second and you restart the engine can take several minutes.....
I did not modify my tank or my boat, I added two plastic tanks of 20 litres each for emergency.
by the way did the level of diesel works on your boat?

Hello Spritz!
My fuel meter works excellent. "Only" one Raymarine instrument and Yanmar's hour counter have stopped to work. I have bought an hour counter from China that I paired with the engine room fan
In the case of an extra diesel tank, I have looked closely at the Inox solution and it is very smart. Maybe it will be a project for me when it gets a little warmer here in Sweden.

I too like XIts solution. I did some climbing around in the area where the tank would be located. This is what the empty area looks like. I thought this photo might be useful for anyone that is contemplating fitting this extra tank: www.23hq.com/J42ds/photo/40729220/originalI'm looking to see if I can find a suitable tank in Australia. One of the limiting factors with this approach is the height of the tank. It needs to sit under the steps that go down to the transom. It also needs to have the bottom hose fitting on the long side of the tank. I did some measurements and it appears there is enough space (at least in our 2 berth 42ds) to get the tank through the opening in the main cabin, without needing to remove the gas tanks. The diesel filler cap (on the aft starboard side of the yacht), connects to the existing fuel tank with a very long rubber hose. Does anyone know where the two other hoses connect on the other side (are these breathers?). Does anyone know if it is possible to connect a second fuel tank level meter to the instrument panel at the nav station so that by pressing the button it shows tank 1 and tank 2?

Dear Syrah, i guess you do not have air conditioning.... No aircon. Does something else normally occupy this space?

We have a 2001 DS40 - 2 cabin version - we had extra space under our rear berth for a 3rd water tank or storage - so we had a custom made aluminum diesel tank built and installed - we have a factory installed 36 gallon tank and the new one is a 50 gal tank.
we used Deltaville Boat Yard to design the tank and it looks like a piece of Picasso art with so many curves and angles -
