No Engine Room Is Too Small

A MAFI Intake Grille in a Kirby Marine Project

This NAIAD rhib project by Kirby Marine showcases that small boats still need engine room ventilation

We are often asked how small an engine room has to be before it won't benefit from MAFI's equipment.


The easy answer for that is there is no engine room too small.


This NAIAD RHIB project we recently completed for Kirby Marine is a great example of this. While this engine room isn't a walk around engine room, it was still in need of good salt mist and spray protection and a great air supply. 


Even though this centre console RHIB doesn't seem to have a "real" engine room, every space that holds engine equipment and is a closed space is an engine room. No matter how small the space it can benefit from Marine Air Flow mist eliminator grillesfans and even air dampers.


No matter the size of the cavity containing your engine and equipment, it will still require good air supply, ventilation, cooling and possibly even directional air. By taking this into consideration prior to building your boat you can alleviate operating conditions that can be detrimental to your new and expensive plant. Often the smaller spaces are more in need of correct air supply than the larger rooms with can be more forgiving. 


Another factor in smaller vessel engine spaces is that they are often directly exposed to the weather. If you boat is punching through heavy seas, often the engine box is being drowned in salt water, or alternatively if you are fishing in the Kimberly region, temperatures reaching over 40 degrees Celsius can mean temps of up to 60-65 degrees inside a small engine cavity. Don't make the mistake of believing that because your engine and electronic gear isn't inside a "full size" engine room that it doesn't need help to work at its best. Often it needs more help and we are happy to assist.
