mystery tank.

[jtylr]

Can anyone shed some light on what this tank is for at the bow of my NB please? 

 

It’s empty/bone dry, definitely not connected to the diesel tank above it (because I assumed it was and now have some diesel to clean from the bilge I had almost finished prepping for paint 😅)

 

1.5 inches tall so some kind of skin tank perhaps?

 

Thanks

Hard to judge really, without seeing 

 

1) All of it

2) Context, i.e. where in the boat is it?

Although I can't see any pipe bosses, it might have been a gearbox oil cooler.

I agree, not enough context or anything to scale from to get much idea.

There are possibly two bosses top left and top right. Or they might be nuts or bolt heads.

Thanks. That more or less rules out an oil cooler. Skin tank for a water-cooled genny perhaps. Can we see a close-up of those bolt heads on it please?

Although the general "context" supports you - a Gas Locker above a diesel tank, in the bow?

Excellent - a diesel powered bowthruster - every boat should have one...

That might be for 3/8 BSP pipe fittings. Plausible. No idea what the tank is though.

[Tony Brooks]

Might the bat have had a small water cooled generator and that was its skin tank. If so, the bosses and tank seem very small.

Potentially, I have the impression it was a fairly well built/specced boat when built 40 odd years ago…

I reckon a skin tank for a genny.  Possibly never fitted.

off I trot to buy a diesel genny then 😅
