Failing Leisure Batteries?

The boat we have owned for a year has 3 x 120ah leisure batteries charged from solar panels via an MPT controller, a 55 amp alternator or from a charger when on shore power. The batteries are of indeterminate age.
Our 12 volt system runs led lighting, water pump, a LEC 12 volt fridge and a Webasto heatre (though only rarely). We have recently fitted a 2000 watt inverter but this is rarely switched on.
Recently it appears the batteries are acting very strangely. Over the course of a sunny day, they charge to 14.4 volts. They then rapidly lose charge to 12.8 volts and seem to sit at that voltage overnight with the fridge running. However, if any load is put on them, say the Webasto or the inverter, the voltage immediately drops to below 11 volts and has dropped below 10. When the load is switched off it slowly recovers to about 12.5 volts.
I have disconnected each battery in turn when fully charged; the charge on a multi-meter shows as about 12.7 volts and matches the voltage shown on the solar controller. All three batteries show about the same voltage so it doesn't seem to indicate one particular battery has failed.
We have just changed the starter battery as this had obviously failed; voltage dropped to below 8 volts, wouldn't charge at all. The starter and leisure batteries were probably fitted to the boat at the same time.
Do you think the leisure batteries have lived out their useful life and need replacing? If so, I'm inclined to replace them with 4 x 100ah lead / carbon batteries. Thanks.

Watermota exhaust

Painting ones boat

Not a question just a report of a fatal mistake. We had the paint on our roof bubbling and badly stained by droppings etc. We deduced this required stripping and re-paint. Following advice read and paint manufacturer recommendation we stripped back to bare metal. A long job as removing the sanded surface kills sanding discs etc, and was eventually achieved using 4" blade paint scrappers; hard work but cleaner and successful. Paint application was 4 coats of primer, 2 coats of pre-coat (undercoat) and 2 coats of top coat. The final finish is quite good for an beginner. Whilst applying the pre-coat in the open air we noticed small specks of paint on the sides of the boat which we then had to clean off with white spirit and re-polish, not a quick job. To avoid this when applying the top coat we booking a polly tunnel paint dock and took the precaution to cover the sides with plastic dust sheeting secured at the edges. BIG MISTAKE. On removal of the sheeting after only 6 days we discovered the paintwork on the sides had 'bloomed' in random patches to ruin the paintwork. The paint manufacturer advises that this is not recoverable(T-Cut and polish won't touch it) and a repaint is now necessary.
The moral is be warned. Our attempt to save money by doing the work ourselves has cost us dearly. Lets hope we can now find a professional painter who will do a good job at a reasonable cost. We have all heard of customers who have paid a lot of money for a finish that fails within 12 to 18 months.

What's the best way to drain the engine coolant?

I need to change the engine coolant in my Isuzu 42 hp engine as it is of unknown vintage. There is no separate tap or drain point to do this, so I have to remove the hose attachment from the bottom of the skin tank. But the bilge will then be filled with a large amount of toxic liquid, so cannot be just pumped overboard. What are the best ways of extracting and disposing of the old coolant easily and efficiently?

2-pack on top of bitumen

My narrowboat was blacked only last year, but in the winter I was forced to do some icebreaking and it neatly removed a lot of the bitumen. I wanted to get it done again, and the boatyard is recommending 2-pack epoxy. Your last feature on the subject (October 2017) said 2-pack would last a decade or more - does that apply to icebreaking too?

Ironworks Company

Do you know anything about the Ironworks Company, which is named as builder of my 1989 57ft narrowboat? I have searched extensively, but I can find no reference to them, which is a pity as the boat seems to be quite well put together, currently moored at Wenlock Basin in Hackney.
Many thanks in advance

Hi I'm interested in getting a canal boat in a few years. I have epilepsy and I was wondering if I can sail a narrow boat with epilepsy even if I engineered the back of the boat to be safe for me. My seizures can accrue months apart from eachother and are well controlled but I was wondering how I go about been allowed to sail a Narrow boat and with epilepsy if I'm even allowed? I shall look forward to hearing from you. Kind regards Isabel.

Water Pump on its Way Out?

Recently our water pump has started making different noises from usual: possibly a bit more gurgly and sometimes seems to run on sightly more than expected after the tap is closed. Although we have had the boat for 11 years, I have no idea if we have an accumulator. There are two mysterious boxes on the hull-side under each side of the pullman dinnette. Should we be buying a new pump at the earliest opportunity? We've had three pumps whist we've had the boat so at that rate we we might be due another one.

Engine vibrations

The engine in my narrowboat, a 3 cylinder Thornicroft 60 on oil filled mounts, is fine when on tickover, but as engine speed increases it starts to vibrate until between 800 and 1000 rpm the vibration of the engine is quite violent. Then at 1100 rpm the vibration stops and doesn't reoccur at higher revs. This has occurred over the last year, before which it ran smoothly at all engine speeds . Any suggestions as to a likely cause. The mounts are about 15 years old.

Blacking over vinyl tar

I found out recently that coal tar products are being banned from January 2019 and my narrowboat was blacked with Rylards Vinyl Tar from new last year and I understand that this product is coal tar based. I've also heard that bituminous blacking doesn't adhere to vinyl tar, so I was wondering which blacking I can use when the time comes, and for touching up any scrapes?
Many thanks
