Boat Anode Resistance Check | ⛵ Sailing Britaly ⛵

[@SailingBritaly]

Hi guys, we have some new videos on the way (turning an ice-box into a fridge is coming next) and you'll get to see how much Emma has grown up in recent months, it is CRAZY... Cheers! Chris, Rossella & Emma 😊

Excellent tip for something that is often overlooked. I like the format of this video. Quick and to the point with no fluff. I'll still love the regular videos you put out, but I'd love to see more of this style of video.

[@SailingBritaly]

Thank you Jacobus, I'll look at doing some more of these. Cheers, Chris 👍

I saw your video in one of the recommendations to one of mine about a Volvo saildrive anode resistance/isolation "mystery". I am actually a bit honoured that the youtube algorithm associated them because your videos are part of the reasons I got started making my own channel. Far from the amount of content you made, but working steadily on it while fixing the boat.

[@paterson00]

Absolutely love this tip. Thanks very much, i didn't know that one.

[@SailingBritaly]

Thank you Paul, it's very rare to see anyone chrecking this, but it doesn't take much resistance to stop anodes from working. A 30-second check can avoid a world of hurt on the next haul out... Cheers, Chris 👍

Thanks for the video Chris, my mesures shows 0.4 to 0.5, i don't know if it's low enough but i want to belive it is :) It would be very useful if you could make a video using your multimeter to detect current leaks as it's an important job and nobody really know how to do it ! Cheers

Good tips 👍

[@SailingBritaly]

Thank you Paul! 👍👍

[@boardelia]

Very useful , thanks !

[@SailingBritaly]

My pleasure! 👍

So good to teach how to check things being right BEFORE invisible long-term failure sets in

[@SailingBritaly]

Thank you. 30 seconds spent doing this could potentially save thousands on a future haulout... Cheers, Chris 👍

[@nomadequipment2177]

Thanks for reminding me of this. My port side anodes are suspiciously intact🤔✌❤

[@SailingBritaly]

This is a common problem as it takes very little resistance to render the anodes inactive. Thanks, Chris 👍

[@jimwesselman]

Is it possible for anodes to be useful on vehicles to minimize the effect of salt on metal? Academically speaking?

[@SailingBritaly]

Hi Jim, you need a complete circuit for cathodic protection systems to work - seawater is the electrolyte on boat anodes - so anodes wouldn't work on vehicles. Chris

[@whyme8068]

Great info! Is there a way to test the anode after changing it while the boat is in the water?

[@flyingdutchman6984]

It is possible by using a reference electrode connected to volts in on your multimeter. You then touch the common probe to the anode and then what it is suppose to be protecting. You should get almost identical readings for both. While possible doing it this way it is hardly practical because of the length of probes you would need. If possible I would dive to check the anodes weekly. If you notice a change in how fast they are wearing, you may have a problem. By doing a regular inspection you will probably notice if the anodes are not wearing away as expected.

Cool.

[@SailingBritaly]

It's not exactly a glamorous subject, but this 30 second check can save a world of hurt on the next haul out if the anodes are doing nothing... Cheers, Chris 👍

Checking electrical bond with multimeter = good. Checking electrical bond with bonding meter = better. However, bonding meter = very expensive.
