Good afternoon hive mind, I want to size a petrol outboard for a little 2x1m metal tender. I’ve never done this before so want to make sure it’s not under powered (like the current electric one is) nor so muscular I’ll look like James Bond in the Lea. Ignore the nest, those squatters have moved on.

Evening ladies & gents, Ive got myself a moonraker tv ariel and a poynting 4G antenna. I want to put them on the same mast, as high up as is feasible. What does everyone else use for masts like this? Any ideas of how to temporarily clamp it to the boat whilst it is static? Cheers,

That’s a good idea. Would do for some of the stuff that I might want to grab. However, some how it is bigger stuff like combi drill, multitool, containers holding liquids etc.

Evening ladies and gents, I want to keep basic tools, engine spares, bits and bobs, a couple of jerry cans of spare diesel, engine fluids, whatever else, in my engine bay. Its a widebeam, so I have space. Question is, how to keep it all organised? I kinda think it would be good to weld something in, something modular that could house shelves, straps, holders, bungee cord etc. Has anyone done anything similar or have any ideas about what I could use? TIA

What part of London ?

Evening ladies and gents and Merry Xmas to all. Just a quick, not so christmasy question for those who have pigeon boxes or have lined them. What mechanism have you got to prop the hatches open? Any mechanisms that would do it incrementally? Most of what Ive found doesn't seem like it would do the job. Anyone go for a car bonnet style prop or a gas strut?

NMEA? Only NMEA I know is NMEA2000 .... ?

The following still needs to be done. 1) Pressure testing the system for leaks 2) Siting the aerator (I’m not exactly sure where this is supposed to go) 3) Setting up the boiler diesel feed in and return 4) Filling and testing the boiler 5) Plumbing the engine cooling to the calorifier coil 6) Plumbing the boiler to the calorifier coil 7) Installing a heat exchanger system to take hot water from the engine to heat the rads, incl limit stat, motorised valve, etc. As seen in the link below: http://boatbuildblog.blogspot.co.uk/2013/06/last-tuesday-i-set-about-installing-new.html

I'm looking for a plumber, which experience fitting diesel fired boiler or ideally ITR Hurricane Heaters, who is happy to travel to the Stansted area. I've done the donkey work, so just need some down for a day. I could attempt it myself but at this stage I'm happy to pay for someone with skills to finish the job. Anyone (know anyone) ?

Wow this thread really has side tracked; serves me right for using the term Hi-Fi. If someone wanted to start converting physical media to digital media today, I would recommend flac/lossless format, without a doubt. Unfortunately when I started, MP3 was the only really viable solution, with 32GB hard drives considered big!

Some interesting responses and clearly a lot of experience in this area. I had actually tried to insight a debate on which was more viable on a boat, especially regards DC vs AC. Dmr, the reason I have avoided a car stereo head unit in my hypothetical setup is because I have to get a Raspberry Pi to handle other aspects of my system, so I figured the HiFi Berry add on will provide adequate signal to the speakers via an amp. As you said, most car stereo's have aux input on the front, which isnt ideal. As for MP3's, it's obviously about storage space. I have around 300GB of music in MP3 format. If simply couldn't store that in CD format and in vinyl, no chance.

Thats useful info cheers. So if you were placing that amp say 5m from the power source and trying to work out voltage drop to size cable, would you use that figure of 640watts? e.g. if I ran 10mm2, I calculate around 10% voltage drop between battery and amp. I am limited by a few factors, space being the obvious one on a boat and the fact that they will be playing MP3 (albeit high bit rate). I'm going for Raspberry Pi + HiFi Berry as none of the car stereo's I have found have the functionality I want. As for the headphones argument. I have a decent pair of sennheiser 25's. However, these don't work so well when others want to enjoy the music/movie. It shouldn't be assumed (although it always is by at least a few) that when someone wants a decent sound system, they intend to crank it up and disturb everyone else.

After much research and advice from the wise fellows of the forum, I'm setting up a media server with Raspberry Pi + HiFi Berry. I had assumed that a 12v dc audio system, much like a cars, with amp, 2 way component speakers and a sub woofer, would be the most efficient way to create a sound of decent quality for less power consumption. However, after doing some hypothetical maths.... 2 Pairs of Speakers = 560 watts Subwoofer = 240 watts Amp = 640 watts https://www.caraudiocentre.co.uk/product_m-alpine-sxe-1750s_p-20265.htm https://www.caraudiocentre.co.uk/product_m-alpine-pwe-s8_p-33197.htm https://www.caraudiocentre.co.uk/product_m-alpine-pmx-f640_p-23894.htm Thats a lot of consumption and a lot of voltage drop to contend with. Are the figures stated on car audio products theoretical or are they typical? Might a 240v system be more efficient in this circumstance after all? Are there any other boaters with a HiFi / audiophile background who could offer an opinion or perhaps explain their setup? Many thanks

My mrs and I work shifts and either of us is often getting up to shower whilst the other is in bed. i had thought of building a box with soundproofing to put it in. Though I'm not sure how well this would work.

Thanks Rebotco. Can I ask, is the entire run to the pump 'downhill' or does the pipework raise before the pump creating negative lift?

Good question. Answers is, I'm learning as I go and presumed bigger meant better It puts out a flow rate, which I wanted but the noise is a bit much. I suppose if it was in the galley most people would be fine it.

Yup flexible hose all over the show. I held the pump in my hand today whilst it was operating and it was just as loud. Jabsco arent far from me so I might pop in with it to see if its usually that loud or if its faulty. I know its a particularly powerful one so perhaps thats why its noisey.

Im talking about 45 ft! I'm think that if Im going to the effort of moving it the ideal place, in terms of noise, wiring and space saving, would be the engine room. Thanks for your experience

Didn't realise Calcutt charged so much. That's extortionate. Does yours have a return fuel line ?

Evening ladies and gents, What better way to spend a friday night than to wonder about pumps. I have a Jabcso Par max 4, 12v the standard pressure model. It's on 1m run to the fresh water tank and is protected by an inline filter. It's followed by an accumulator for good measure. All linked up by flexible hose before the main hep2o pipe run. However, due to reverse layout, my bed is pretty close to the thing and it's loud! So, while the lining isnt up and its not too hard to do, I'm considering moving the thing to the engine room. Has anyone done this? Are there any problem's I havent foreseen with this method? The manual suggests pump placement should be no more than 2m away from the tank. Given that the pump will effectlivey be gravity fed when the pitch of the boat is considered, I'm not sure how important this is? Last resort is making a soundproof box, but I'd much rather be rid of the sound altogether.

Cheers for your help Dr Bob. Im assuming cat7 being unshielded means its susceptible to interference? Would putting it in conduit solve this?

It seems like Raspberry Pi is the solution and I'll just have to do the requisite learning. I'll take your advice and run a network cable down the boat whilst I still can!

Cheers Robbo, seems great for Audio but not so great for Video.

Youre probably right. Its just that with my fit out I feel like I am having to learn so much all the time, be it wiring, plumbing, carpentry... the thought of having to sit down and learn another thing feels like a pain. So assuming I had KODI setup on Pi connected to a usb hard drive, what is the best method of receiving that data to lets say 2 video outputs (TV x 2) and 2 audio speaker sets?

Moving on the from the traditional and more obvious arrangement of a car head unit, amp and speakers and perhaps a 240ac HiFi to supplement... So the I am looking to tick the following boxes. 1) One centralised media server - films/music on a hard drive 2) Be able to play said media from 2 locations (Saloon and Cabin) 3) Be able to introduce media from another device via spotify, apple airplay, vlc and the like.. As I am yet to line out, wired solutions would be fine. I would of course prefer to run as much as possible on 12vdc however, I think Raspberry Pi and Arduino might require too much learning. I haven't yet decided on speakers, however, 6x9 car speakers and a slimline sub would hide nicely in the lining. Has anyone had any success bodging together a similar system?
