Cabin Type and Size

We need to know the type of cabin and its square area and height so we can work out the cooling requirement in Btu/h. A raised deck saloon will have much more glazing than a flush deck saloon so the cooling load or K factor will be higher.  Please select the cabin that most closely matches yours.  If there is nothing that matches the area you are looking to cool select the ‘Misc cabin’ and you can set the K value manually below.

Sailboat Cabins K Value Power Boat Cabins K Value

Raised deck Saloon 32 Flybridge saloon 35

How accurate do your measurements need to be?

We do not need measurements to the mm and appreciate that the width of the cabin sole (floor) can be significantly less than the width at the head lining. We are looking for the average to give us an approx area to give us our BTU/h load

Sharing a Compact unit with multiple cabins

It is possible to cool more than one cabin with one AC unit.  To do this we split the air to a delivery cabin in the main cabin and add a second closable grill to cool the smaller cabin.  If you would like to do this, select the first cabin, then when you select cabin 2 you can link it to the first cabin by selecting ‘AC Unit to be shared with adjacent cabin’

You also need to consider the return air from each cabin to ensure you get the correct amount back to the AC unit. If the AC unit is in the main (larger) cabin for example and you have a second outlet into a forward V berth you would need to put a louvered grill in the door of the V berth so that you are getting return air back to the saloon.  If you had the unit located in the V berth with an outlet to the saloon it will cause reduce the temperature in the V berth before the temperature in the saloon has reduced significantly – in this case you may need a larger grill in the door joining the two cabins or even look at ducting air from the saloon back to the sleeping cabin.

Effect of the Level of Glazing

If your cabin has lots of windows, sky lights or full height glazing we may need to adjust up the K value for the cooling load for your cabin. Equally if there is very little glazing we can revise the K value down manually.
