Re: [PSUBS-MAILIST] idea/keel cooling
Hi Ian, that s a pretty good idear.
The forward 2/3 of my keel cooling is use to cool the Diesel engine.
But the same style build and allready with coolant
filled keel area under the aft section is used for nothing.
To use is for an aircondition unit to get the temperature in the
engine compartment done is a clever simple solution.

You can see the not used cooling "Pipes" in the right side of
the picture welded as two triangles below the aft section.
You can see also the two stainless steel pipes with
coolant water coming down from the engine and ending
after assembling in the forward section.
