This video series is perfect. I am sitting here watching ordering parts and wires as I go and can't wait to watch it over while installing items in my little runabout, Cheers for your work with sincere thanks from Victoria BC Canada

[@BoatFittings]

Hi many thanks for your kind comment. Kind regards, Richard

[@jamesneirinck413]

Great how-to videos so thanks for putting these out. You commented you prefer solder vs crimp connections. My experience is driven from aircraft standards and those specify crimped connections using good quality AMP / aircraft grade terminals that crimp both the stranded tinned wire and also the insulation covering the wire. Also need to use a good quality crimp tool for this purpose. If you use low quality automotive style terminals and the simple single point crimp tool they only crimp to the wire and poorly at that and will fail if you pull on it. The correct AMP / aircraft style double crimp connector crimped with a good crimp tool will not pull out or fail. We tested them to failure and the wire will always fail first (so as strong as you can get) and the crimped connection remained intact. The crimped aircraft terminals are done that way for the strength but also for the same reason we use tinned and stranded wire, never solid wire, because of the possibility of flexing and vibration which is the same type environment on a boat as on an aircraft. A soldered connection is more prone to fail if flexed or subject to long term vibration. The added benefit of using AMP / aircraft grade crimped terminals is it is easy to do a new connection or add another terminal on the water as you don’t need power for soldering or the soldering equipment. Easier to carry a good quality crimp tool, wire stripper and extra terminals. Just a suggestion for you to consider or try yourself.

[@jeffclapp7330]

As a note, ABYC Standards do not allow solder as the sole means of connection for an electrical connector. You can crimp AND solder, but solder by itself is not permitted. So if your boat may be subject to ABVC Standards (or you want to meet typical standards) then crimping should be used or used as well. Not probably an issue based on the accent in the video, but I'm not sure of Euro/UK standards and if they differ.

[@jeffgriglack9624]

@@jeffclapp7330 I believe that soldering is not recommended because it can make the wire more brittle. You want the water to be flexible. Also, he "tinned" the wire with solder, but he should have already been using tinned wire.

[@BoatFittings]

Hi many thanks for your detailed comments / suggestions. I agree that good quality crimping tools and the corresponding connectors make for a robust solution. In many cases though people use cheap and nasty crimp tools leading to a poor joint, which in my opinion makes soldering more reliable compared to many poorly crimped connectors. I do take on board your comments though, and thanks for making them. Kind regards, Richard

I’m working on a project 22 foot sailboat. I’ve stripped all the old wiring in it and you made it easy for me to understand how to wire the whole boat I like how you broke it down from the beginning from scratch thank you

[@waterboy8999]

Brilliantly simple, but very well explained, thank you very much. I didn't think it was rocket science, just a bit overwhelming seeing the back of the control panels, but I did think its only one wire at a time.

I have found it easier to understand once I get the concept of a circuit in my mind. A circle; starting and ending at the battery going out to the appliance on positive and back from the appliance on negative; with the various switches and fuses on the positive side. Good videos, thanks.

[@timothyhowell6931]

Thank you for this great and clear demonstration. I have a 16’ aluminum boat I recently bought and found all of the electrical components wired directly to the battery. So I want to take what I learn from you and rewire the whole boat. So the battery is in a single walled aluminum compartment, and I’m wondering if it would be safe to attach plywood or pcv to the inside walls of this compartment to attach all the electrical components to eliminate penetrating the aluminum walls with a bunch of screws?

[@andrewcase9652]

Very well explained and looking forward to Part 3. I am hoping you will deal with the challenge of multiple interior lights and running out of switches as the series progresses . Thanks again

[@BoatFittings]

Hi thanks for your kind comment. Thanks for your suggestion on looking into the wiring of multiple lights - I will keep this in mind for one of the videos in the series. All the best, Richard

[@hoverwatch4131]

Can you run a busbar for all your led lights back via a single wire to the switch/breaker to avoid overcrowding the switch with more and more wires as lights are added (or any other system where things are added on. Subject to load obviously).

[@2frogland]

crimps are normally preferred in harsh environments, great aid for the diyer

[@danielboughton3624]

Which is why they are used on automobiles and pretty much everything else. There are people who insist on soldering everything because they had a crimp they did go bad but they can never answer why a 30 year old car still has good crimps. If you are going to solder then get solder connectors v.s. using crimp ones and then add shrink wrap to provide some stress relief as well as short protection. The big issues with solder beyond the time to do it are corrosion due to the flux and cracking due to the hard spot. Modern solders also take a lot of heat and that means melted wire covering which is perhaps why silicon is being used here.

[@kimberlyjacobsen4148]

I would use the brother label maker pt-e500vp. It can print on heat shrink. Love it. And it was surprisingly affordable.

Hi Richard, brilliant series. i've just discovered your channel and will be bingeing your back catalogue every day! What a mind of information you are! Even just to remind oneself before carrying out a "job" your series is brilliant!. I have an old 1992 35ft Nimbus DC currently based down in Cornwall (legs reconditioning!) with so many jobs, my early retirement will definitely not be idly spent! And if you ever want to set up a boat series, I'm happy to work with you to make it happen! I have 2 x VP AD41's on sterndrives, so plenty of electrical stuff to work on both engine and domestic!! I dearly want to replace a switch panel on the helm station, as the bakelite switches are all perishing, and was wondering if you have contacts other than the usual large distributors that I might try finding old replacements? New may be better for waterproofing, etc, but will change the look substantially? Keep up the great videos. regards, Daniel

[@mistercaptain2000]

The amount of positive comments is testament to how great your videos are. Thank you. I have a question: why couldn’t I use the negative bus bar on the switch panel for individual negative returns? On my switch panel the negative bar is of a similar gauge to that of the positive one, making me think it should handle the current that would return through it if I connect the peripherals there directly. Also, if no peripheral negative returns go to the panel bar, then why do you need the fat return from panel to battery? It would seem you would then only need a cable to handle the current from the panel pilot lights?

[@BoatFittings]

Hi thanks for you comment / questions. I don't want to comment on your specific switch panel, but I if your switch panel has a good sized negative bus-bar then it would seem reasonable to make use of it. For your second question, the 'fat' negative return cable was used mainly as it came as part of a set (positive and negative) than the need for a fat wire. Kind regards, Richard

[@BoatFittings]

Hi thanks for your question. Actually the negative wire happened to be part of a set purchased together, so it seemed a shame to waste it. Other than that no reason at all, and a lighter gauge wire would have been absolutely fine - well spotted. Kind regards, Richard

I looked but could not see question & answer in previous posts, so here goes: why does the negative from light not connected to negative side of switch panel, but instead is run to negative bus? Or does the switch panel not have a negative side and for my simplistic brain, would it make more sense to put the negative bus beside switch panel?

[@wellyftw]

This is really useful for someone trying to figure out the wiring in their narrowboat! A question I have is for when you want to wire up multiple lights. Because the wiring is all hidden on my boat, I'm not sure how it's currently wired up. What would be the most likely way that they've been wired up? I can see on the switch panel there is just one switch for internal lighting. I have two lights which aren't behaving properly - one of them is not lighting at all and putting my multimeter on the wires to the light shows 0 volts, and the other at the front of the boat just flickrs although it lights dimly and so trying to work out what the problem might be. Any suggestions of where to start looking? Thanks very much!

[@ladygardener100]

Neat video. One thing i dont think you explained is why you use solder on what is essentially a terminal which is forced on the the wire i have never seen solder on boats . I understand that it is not used to join things due to vibration

[@BoatFittings]

Hi thanks for your question. In my experience solder has never let me down, but crimps sometimes have. I am aware that some people prefer to rely on a crimp. Kind regards, Richard

[@petemac8229]

curious why you run the component ground/negative all the way to the bus bar versus just writing the component circuit to the negative switch bus? What drives the choice? Assuming the switch is at the front and the bus at the back would you just run the wiring to the closest ground? It may make sense as you build out the boat?

[@BonkaWonka816]

I have a question about 2:02 Why did you solder it? Is it an alternative to crimping?

[@redhotcannon]

Don't do this. Marine wiring basics - All terminals should be crimped & insulated. It's ok to use solder + crimp, but not solder alone. Also "tinning" the end of the wire is not a substitute for marine grade wire that's tinned all the way through and the insulation is made to handle higher heat and exposure. Remember, you can't run away from a fire on a boat!

[@kimbirkebaekeskildsen637]

Great video which explain boat wiring in an easy understandable way, but sorry that I have to be the grumpy old man, but a fuse between the positive side of the battery and the master switch is mandatory, to be in compliance with the safety standards for boats, booth in EU and for USA. Imagine what will happen if a shortage happens between the positive side to the negative side somewhere between the battery and the switch board. Worst case scenario is a fire onboard, overheating of the battery, which might cause the battery to explode. So please add a main fuse. How to dimension the fuse? Calculate the total possible load and add 25%.
