Monitoring Battery Temperatures

If your batteries are getting HOT then I suggest your battery capacity is too small for the load or conversely the charger is running at too high a rate.

Either way you can test the temperature by placing a spare hand (sic) on or near the battery bank.

He might be better measuring the temperature of his loo?

No, a surface vessel.

 

This guy came to a stick end to his "boating" if I remember correctly.

 

??

 

It is a surface vessel.  He wouldn't get far if he tried to "dive...dive...dive".. 

 

I think......he went bankrupt....?

I saw it for real some years back...moored at Botany mills . Very sinister.

Do you have an altimeter on your boat as well?

A lot of boats, including mine, have a barometer aboard. An altimeter is just a barometer with a different scale under the needle, so effectively yes.

You need a barometer.

 

You can then tap it repeatedly and annoy the wife.....who says " if you want to know the weather..just look out the Bloody  window !.?

But how do you know if its the boat rising or the atmospheric pressure falling

You don't. You have hit on the fundamental problem with using a barometer as an altimeter. It has to be set at a known height and any weather induced changes will cause it to read wrong. Hence aeroplanes relying on them accidentally flying in to cumulogranite clouds.
