Thanks for sharing all your knowledge and experience with these videos.I'm really enjoying seeing whats involved in each part of your restoration.The Whitsundays are such a beautiful part of Australia and a wonderful playground to sail.Would you consider doing a video on how you both got into sailing and where you gained your experience?Cheers!
@@jimmyd6279 thanks Jimmy, really glad you’re enjoying the videos. We absolutely will take a trip down memory lane at some point in our filming but for now you can read a bit more about our backgrounds here: epoxycraft.com/projects/is-brilliant-ii-their-real-life-movie-set/
That seems plausible but where is the mild steel and why only the angled surface? Could have been fuel with high iron content water causing a bacteria but water settles…mystery.
@@jamesmarshall2015 the tanks were only joined by a single rubber hose and the diesel that travelled from the iron tank into the aluminium tank. We think it was the diesel that carried metal-based sediment, which then had no mechanism to be flushed out of the aluminium tank and therefore accumulated over the years. In the video you can see how that corrosion is still ongoing from those bright metal sections where the sludge gets scraped away.
@@normlarsen4803 the black iron/steel, is what the original boat tanks are made of. The aluminium tank is an add-on installed by the previous owner. The starboard black iron tank is right next to this auxiliary aluminium tank (separated by a bulkhead) joined only by one single rubber hose. There was no water in the auxiliary tank and the sediment was 100% ferrous metal-based, which makes us think it had come from the steel tank via the diesel. It then settled on the bottom of the tank, which in this case, because of the angle, was the diagonal face. Just gravity at work there!
Lot of bronze plumbing fittins being used in aluminum aux tank? esoecially if electrolysis is aconcern? why are main tanks stainless and aux tank alumium???
Hi, the main tanks are black iron aka steel. The fittings on those are also steel (welded). The auxiliary tank was added on by the previous owner. He probably chose that material for ease of manufacture (plus all modern fuel tanks are either aluminium, stainless steel or polypropylene - not black iron). The fittings we’ve just put into the auxiliary tank are brass and they’re isolated from the aluminium by PTFE tape, which is the recommended method. There was an original brass screw-in drain plug and original brass elbow, which we just replaced and which had been in that tank for close to 20 years, also isolated with PTFE tape, neither of which were the cause of the problem. Hope that answers your questions 😉

@@brilliantsailing Thanks for sharing,that was great!
@@jimmyd6279 we’ll definitely cover more of the ‘how we got into sailing’ down the track 😉
It must have been very satisfying to get rid of all that corrosion. What a mess!
Sure was! A bit of a surprise too!!
Quite the corrosion in the fuel tank but another great refurbish.
Thank you 🙏🏻 It was a bit of a revelation but good to have got it fixed - and ticked another job off the list!
I suspect that it may have been galvanic corrosion between the mild(?) steel tank with the ally tank acting as the anode.
