Re: Another "best deep cycle battery" thread

Update : Unfortunately, the GC2s are too tall. I'd need to make a new battery box, and I can't be arsed. I've had to go with the US Battery 24 DC XC2s. I bought them from a Powerstride agent and they...

Re: Auto vs manual inflate lifejackets

Sure, why not? Dinghy sailors wear that kind of thing all the time. Usually, though, cruising sailors are on the boat long enough to want something more comfortable, and flexible - ie layers you can...

Re: Auto vs manual inflate lifejackets

Here is an interesting explanation of how they work. My Mustang appears to have the Secumatic mechanism, which contains a small pill that dissolves in water. These are prone to going off if the pill...

Re: Auto vs manual inflate lifejackets

How is that pertinent? (answer : it isn't). We're discussing whether auto inflate is safer than manual, not whether to wear a life jacket at all.

A knife will cut through standing rigging, will...

Battery charge vs. voltage under load

I was testing my old house bank today (6 years old). Two group 24s of (allegedly) 85Ah at 20 hours.

Does anyone know if the chart on page 68 is correct?

Re: Another "best deep cycle battery" thread

The GC2s would also address a couple of things that annoy me right now : the time involved in removing and re-installing 12 screw caps to check the electrolyte, and the fact that the batteries are...

Re: Another "best deep cycle battery" thread

Thanks for the suggestion of the 6V batteries. I'll have to measure the box next time I'm at the boat. But there's loads of room above the battery box, so it could be modified if necessary.

Another "best deep cycle battery" thread

My house bank is two group 24s (although I have thought about just putting one group 31 in there).

Right now they are Powerstride 24 TMs, which are 6 years old, and I want to replace them before...

Re: trailer sailer electrical refit: safety first advice

Re: Marina personnel attached battery wrong

The tachometer gets its signal from the alternator, so fix that and the tach should be fine.

Do you know what electronics would have got switched on?

Re: Marine multi-pole connector?

Another advantage of the busbar : it took a while to figure out the NMEA 0183 connections, between VHF and chartplotter, and the ring terminals allow you to easily alter the connections. It is likely...

Re: Good Small Boat for Older, Fatter Woman to learn on

Suggesting triathlons as a way to get fit is a lot like suggesting a mission to Mars as a way to get into electronics.

Re: Best MultiFunction Instrument

In my opinion, the best use of the Ipad nav apps is as a planning tool, and as a backup to a proper marine device.

The price difference between an MFD, and a chartplotter, is not that great and...

On my last haulout a year ago, they replaced the old packing with Western Pacific Tefpack. So far this has been great. It's almost completely dry, certainly a dramatic difference in leak rate from...

Re: Painted topside maintenance and care?

Mine's 30 years old and not looking too bad. A little faded, but the only way to tell is that an area has been repainted and is darker. Pretty impressive paint.

Re: Painted topside maintenance and care?

If the paint is Awlgrip, they recommend washing with Awlwash regularly, and treating with Awlcare. They recommend NOT waxing it. Dont buff it either, the heat will damage the finish.

Re: Lifespan of a Diesel Engine

IMHO, an engine with those hours could have years and years of life left, or be ready for the scrap heap, depending on many factors. An engine survey will tell you which one is the case.

Re: Lifespan of a Diesel Engine

This is one of those "how long is a piece of string" questions. To wear out could be anything from 5,000 to 10,000 hours, if used regularly and taken care of. I would venture to say that they rarely...
