Re: Keel cooling

you will require a lot of formulas.

the cat certified marine analist hand book has the formulas.


what is your enigne going to be and the power output?

but you need details as engine cooling water heat rejection data but you only know this after you select the engine.

then you have to consider auxillary equipment also inline with this system.


and most important the vessels area of operation.
