Gulf 32's have air vents at the stern for the engine
compartment, which helps, in addition to the finger holes in the floorboards in the pilothouse that well exceed the diameter of the intake pipe. As for cabin ventilation, I pity all those people out there without a pilothouse as we enjoy 360 views, natural light, and massive ventilation opportunities! Enough smugry.
Anyway, here is my blog post on the cabin heater I installed a few years back:Stories of Aeolus- Our Gulf 32 Pilothouse: New cabin heater, bilge hoses, windlass batteries and..
The heater draws air from the space adjacent to the diesel
, and I have long wanted to have it suck air directly from the lower footwell of the cabin but there is a design feature of these things that makes running the hose rather tough. It is possible, but not a bit of a pain.
As for these high end CCV filters like the one linked and the Racor
, it is unclear to me why thousands of cars and boats are run with the crankcase fumes plumbed right into the air intake and yet these devices are sold as though there is some need to filter that air separately. It may be that these big models are used on commercial
trucks which have higher standards of one sort or another.
In any case, thanks to all for the input and now I am heading out for another three weeks in British Columbia
and Desolation Sound! The good ship Aeolus is enjoying lots of trips this summer and plenty of time in that warm norther water
(how? what? check temps in Pendrel Sound!).
