Boat Electrical Made Easy. Part two. And some sailing.

[@simonbell6310]

Excellent tutorial. I did this stuff at school 45 years ago and never got it. This is great. As was the sailing footage at the end and also the Spanish accompanying music. Brilliant. Part three next.

[@SVImpavidus]

Simon that's fantastic. Thank you Sail Safe mate. Ant, Cid & the pooch crew.

[@trevorread5200]

This is superb stuff; so practically helpful for old novices like yours truly. Your clear explanations, gradual step-by-step progress and regular recaps mean I am beginning to understand something I had always found completely mystifying. MERCI BEAUCOUP

Your getting through the videos then. Glad your enjoying them.

just come across your content and it is great.

Welcome aboard Bill! We also have a web site with blogs and technical stuff on. We are still building it but it's getting more info as we move forward: svimpavidus.com Enjoy te channel. It's good to hear from you in the comments. Sail Safe Guys, Ant, Cid & the pooch crew.

Thanks for making these videos, they are very helpful. I've been to Majorca twice back in the 80's, I was very young.

Brilliant! (I love the way you Brits use that word!) Although I already knew this stuff, I found your presentation to be pure genius. I've made a part of my career in adult education, and I wish I was as good at as you are. Thank you

[@SVImpavidus]

Thank you for such kind words. I guess its about explaining things in terms people will grasp better than being all technical and jargon filled. We are passionate about sharing knowledge and experience and that helps too. This is a 4 part series and we are working on the last part that will tie everything together. We want folks to be able to fault find or diagnose problems for themselves. Hopefully then they will be able to go on to fix them because they understand how they work.Thanks for watching. Glad you liked it. Ant.

[@SVImpavidus]

Sir you are a gentleman! Thank you so much for your kind words. We Just want to help others and pass on what we have learned over the years. Ant has actually lectured in a couple of universities in the UK. He would not say so but, he just loves seeing people get the subject and master it. He was once invited to lecture at the Science Museum in London and I think it's one of his great achievements. I am very proud of him, and having such good feedback just makes me blush. Thank you. Cid. xx (Ant & Cid) SV Impavidus.

Hi, thanks for teaching and sharing. I am learning a lot and electricity always was an area that i could not find someone explian with simplicity this knowledge, Paul

[@SVImpavidus]

Thanks Paul. We are still putting together part 4 It should be up on YT soon. Ant

[@WanderingKnapps]

Great sailing info. We are a family of 5, just buying our first sailboat. We are new KZbin friends and just found the Facebook KZbin sailing channels. I think we are in for a great new community

[@SVImpavidus]

Welcome aboard SV Impavidus! We started sail with our family many years ago. We believe it gives children a great outlook and understanding of their environment. There are so many thing they learn on a boat. Where are you currently sailing? What boat are going to buy or are you yet to make the decision? Ant & Cid xx

[@josephlai9759]

Hi, I cannot get my head around when you said the resistance for the 24V is lower than the 12V when the calculated figure clearly showed the opposite. How is it so? Appreciate your clarification. Thank you.

[@SVImpavidus]

You are correct. While the 12v is 16.66 Ohms and 0.72 Ohms the 24 volt is 8.3 Amps @ 2.89Ohms. The calculation is on the paper but I miss read the script. We have put a correction in the notes as we cannot re-upload the same video or edit it after loading. Sorry if this caused any confusion.

Hi mate. It is in BEME and Binge watch from the beginning. Ant.

[@normanboyes4983]

Bit disappointed you did not cover the heating effect in the cables?😉😀👍

[@SVImpavidus]

I thought we would do that with cable calcs Norman. Or with heater elements? It's a bit of a job to cover so much without going into a lot of detail or just covering the basics that will get people knowing how to fault find or repair. I debated the magnetism and poles subject in my head for ages trying to keep it simple but still making the point. Perhaps we should make it a series rather than trying to keep it to 4 videos there is still a lot to cover? Sail Safe Ant.

[@normanboyes4983]

SV Impavidus (Ant & Cid Sailing) Ant - I think you are doing an excellent job - I was just teasing about (I squared R).👍

[@SVImpavidus]

@@normanboyes4983 I have a plan for transformers more about AC and safety. I think I should do a simple charger showing diodes or rectifiers. Reversing solenoids for things like winches. Double pole switches. and a typical boat schematic. Charging from alternators, solar and wind gens. Before going on to fault finding. That's a lot to cover in one video so It is most likely going to go 5 or 6 videos on just the basics. Any suggestions would be greatly appreciated. Sail Safe. Ant.

Hi Ant. Thank you for all the great information. What software or application do you use to draw the electrical schematics that are shown?

Hi Mate I have just done a bit on this in our latest video. Enjoy.... kzbin.info/www/bejne/lXqwlH5optVqnJo

[@kennethswiney9283]

12 v / 16.66 = 0.72 Ohms 24 v / 8.3 = 2.89 Ohms How is the resistance lower in a 24v system ?? Please explain ???

[@SVImpavidus]

Kenith, Will do we have had the same question before, But a full explanation will take a bit of time to type and we set sail at first light. We will get back to you when we are a few miles south of the coming weather system. Thanks for watching. Ant

[@SVImpavidus]

Kenneth have you watch the next video? We put a better description in it? At the beginning. Or give us your email address and we can send you a very detailed explanation with diagrams. Best regards Ant.

[@s.rosenberg4334]

Great video, but why the heck are you towing your dinghy with the engine onboard the dinghy?

[@SVImpavidus]

On short trips we tow it as it is lest trouble to do that than fit the davits, lift the dingy up on the davits and then go the whole process again when we get where we are going. AS we have a tail gate stern. Sail Safe mate. Ant, Cid & the pooch crew.

[@wpgskp]

Hi, please can you help me understand why in series batteries setting we do not have increase in Amps and vice versa with parallel. Thank you

[@SVImpavidus]

Hi, Thats a really good question! I will try to explain. When batteries are in series the voltage goes up not the Amp hour rating. 2 x 12 Volt batteries with 100 Amp/h will give you a 24 Volt battery bank with 100 Amp/h rating. The Voltage has increased not the Amp/h rating. If you put the same two batteries in parallel, the voltage stays the same. However, the Amp/h rating will be 200 Amp/h. Going back to our water tower explanation. Think of it like this; Parallel: Adding more water to a water tower gives you more water to use, (Amp/h). As there is more volume of water. But, the height or pressure of water (Volts) does not change. Series: Making the water tower higher will give you more pressure (Volts) but, not more volume of water as the volume of water is the same (Amp/h)..... I hope that makes sense. Sail Safe mate.

[@dongibbs4450]

Hi, when I worked in the electrical industry we always thought electricity in a battery flows from negative to positive have I been wrong all these years we would always put fuses in the negative line.

[@SVImpavidus]

Hi Don. Well actually your sort of correct. There are two things that contradict. Firstly there is what we refer to as current flow, from positive to negative or in AC live(hot) to earth(ground) But actually the flow of electrons is the opposite. From negative to positive. Negative remains negative because it gives up electrons to the positive. However, fusing on the positive side means in the case of a switch or fuse being blown or open the remainder of the circuit is harmless or negative /grounded. It's a very good point you have made in this comment and something we should cover at a later date when things get more in depth. Thanks for taking the time to comment. Hope you enjoyed the video. Ant.
