Hi and thanks for the response. I am sure I have seen 'Substantially built' on a document before but so far cant find anywhere that says this must include the hull . Would it be possible to show me where you got that information from ?

Hi Alan can I ask where you found this information ? I can only find (g)watercraft built for own use, provided that such watercraft are not subsequently placed on the EU market for a period of five years beginning with the date on which the watercraft was put into service;

Sorry it seems my question was badly worded but a couple of you seem to understand what I was asking. Also does anyone know what is going on inside the linked unit ? Is it really a battery to battery charger as just looks too small or is it some sort of relay ? https://www.ebay.co.uk/itm/196910036112?_ul=GB&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338990947&toolid=10001&customid=eb%3Ag%3Avms%3Aeb%3Ap%3A196910036112%3BCjwKCAjw-qi_BhBxEiwAkxvbkGUMDf7Y2zB4z_NE6InJOQUk-6t1zA7tRzjS1o--Ie16cOolEENNvxoCsXwQAvD_BwE&gad_source=1&gclid=CjwKCAjw-qi_BhBxEiwAkxvbkGUMDf7Y2zB4z_NE6InJOQUk-6t1zA7tRzjS1o--Ie16cOolEENNvxoCsXwQAvD_BwE

Hi can you clarify you are saying the vehicle starter battery and all vehicle electric needs ( Lights / wipers / fans / ECU ? Radio etc ) can now only take a maximum of 4A from the alternator ?

It sounds to me you are saying the measurement in the pic above is the problem . Is that the case ? If so I would just file it down until it fits.

This is not the first first time these boats have featured in the local paper. https://www.northamptonchron.co.uk/lifestyle/outdoors/mystery-solved-over-saudi-coffin-that-washed-up-on-northampton-field-in-christmas-floods-3093961

This guy has kindly added some videos on installing bubble testers on boats that I found useful. As I was starting from scratch going for thick wall 10mm pipe just made more sense to me . I do a test every time I replace a bottle. it just seems a sensible thing to do. My bubble tester is installed in the gas locker and is easy enough to see.

This is an interesting option . Have you a link to something that would not get confused by the cabin Roof that is only 25mm away ?

Ian seems to have it spot on from my experience, It just behaves like an Mppt or mains charger.

I can understand that and I do believe the Tr Smart 12 / 12 - 18 will achieve what you are after. I would be very intrigued to hear a response from Ian / Nick / Tony as I am not an electronics engineer.

On the boat pictured above the the box section was 2.5mm wall. After drilling a 4.2mm hole and using an M5 tap I hung my 80 odd KG weight off it and felt comfortable I could not make it fail no mater how hard I tried. If it was a single point I needed I would perhaps go up to an M6 just to be sure. If you find a small diameter drill bit and put a mark or tape at 40mm from the tip you will soon know if you are hitting one of the supports or not without causing too much mess.

As far as I am aware the cheapest model in the current Victron range that will do what you want is the Orion-Tr Smart 12 / 12 - 18. This unit is actually sold as a charger and not just as a converter. My understanding is that if you proceed with the unit you have purchased it may possibly work , but as far as I can tell it has no current limiting so if the batteries ever try to pull much more than the 9 Amp rating the internal fuse will blow. I have recently installed a Tr smart for a similar situation and have so far been very impressed with it as a good value and quality product. With the Bluetooth app you have lots of options to get it configured in the way you want . I hope this is of some help and I understand your confusion as Victron seems to have over a dozen products using the Orion name. As a side note and I know its not what you asked , but If it was me and I could find the space to put it I would spend the money on a small solar panel and mppt.

It is fairly likely you will have 25mm x 25mm steel box section roof supports mounted at 600mm centres down the length of the boat. If you can locate one of these it will be fairly easy to drill and tap a thread.

Ok that all makes sense. Thank you .

Hi and thank you for the quick replies. It seems I was wrong in my belief that it was bad practice to leave the tank half empty. Hi Tony can you please clarify that the unpainted inside surfaces of the tank are not going to rust and cause problems ?
