Connecting battery negative to hull

A few months back I had someone look over the boat and I was told the battery 0V must be connected to the hull bonding point to pass the BSS. Is this correct?

Stainless steel water tanks.

This is not a question but our experience. We found water in our cabin bilge and went through the process of checking pipework for leaks (none), checking condensation collection, (none) and nearly gave up thinking the hull must be leaking. At only 7 years old and having had an out of the water full survey before purchase we took it that a stainless steel water tank would not be the problem. We finally disassembled furniture, bed and front bulkhead to gain access and found that indeed the corner weld were leaking and also causing rust to appear in the domestic water supply, which we had put down to sand etc in the canal side water feeds. It transpired that the tank had been welded with MIG welding and stainless requires TIG welding. It cost us nearly £700 for a new tank and much hard work to fit and re-build the boat and much lost cruising time. This would not have formed part of the pre purchase survey. The moral is, check your bilges regularly and the colour of your water from the taps etc. Our new tank now includes an access hatch to allow us to inspect the condition with the tank drained down. Hope this is of interest.

Solar panel wiring

Our boat has the output from the charge controller feeding direct to the Domestic Busbars which are fed via an isolator and fuse from the batteries. Should the Solar panel wiring go direct to the batteries with a fuse for protection. We don't usually isolate the domestic isolator.

Boat Width

Does the width of a boat matter when you exceed 6ft 10". More specifically is a say 9ft boat able to access more canals than a 10-13 ft boat.

Stove or aga

Hi after living on a Narrowboat for 5 years we've decided we have outgrown our boat and looking to buy a widebeam( not everyone's taste) but living on a boat with a 8 yr old boy we've outgrown a Narrowboat and don't do much cruising so widebeam is far more practical for the next few years. Would you go for a stove or a solid fuel cooker? Tia for your opinions

Diesel additive

We get our new boat delivered in few days and I'll need to fill up with diesel for the first time. Should I use a fuel additive from the start, and on a regular basis, to inhibit the diesel bug and help precipitate any moisture? I'm having a Fuel Guard filter system fitted for added protection.
Thank you

Exhaust lagging

I would like to ask if it would be a good idea for me to lag the hospital silencer in my engine bay? If so are there alternatives to the lagging that is mostly sold for exhausts as it appears to be quite narrow and would take a lot and is expensive. I was wondering about domestic regular hot water lagging?

Repainting a water tank

Is there any rust preventive treatment that can be used on existing rust patches in a potable water tank before repainting ? Rylard Paints seem to be the only supplier of bitumen water tank paint.

Gettin Goin

I'm a 25 year old fella. I was born on boats and lives on the canals for most of my life. It's something that I have decided I cannot do without. However, with section 8's being a thing of the past. No mortgages for narrowboats unless you want ridiculous interest rate and frankly not having £15,000 laying about. What can I do? I'm not after much, just a 32ft plus springer with a running inboard diesel, hull in decent nic and a bsc!
Any advice?
