[Public-list] Solar Vent

[Jim Davis]

With air flow through the bilge area and other minor openings you are going to get mixing of cabin and engine room air.  the trick is to try and maintain fore to aft air flow as much as is reasonably practical and not sweat the small stuff.  On a boat with a gasoline engine you have to have two vents to create air flow through the engine space and bilge.  For heat dissipation reasons you should have this same air flow on a diesel boat.  

A simple suggestion  3 and 4 inch computer fans are cheap and move a lot of air.  They also draw very little current and run on 12 volt DC.  They are also brushless so sparking isn't a factor.  On Isa Lei I have two that are running 24/7 feeding a pair of cowl vent aft.  This creates a positive air flow at all times.

Enjoy
