woman blowing pedals rajdeep kataki 220911 640x309There has long been a debate about air cooling versus water cooling for marine refrigeration systems. Water cooling has traditionally been generally accepted to be between 25% and 35% more efficient in warm/hot ambient conditions, but some of that efficiency gain has to be offset by the energy required to run a water pump.

The Frigoboat Keel Cooled system is water cooled and does a fantastic job without the need for a fan or a pump. That will be mentioned later, but the following compares air cooled systems to traditional water cooled systems using sea water with a pump.

Many boaters these days seem to be opting for air cooled refrigeration systems even though they’re heading south into hot climates, and despite the notion that air cooled is inherently less efficient than water cooled. Why is that?

Mangoes for Life

mango seller     Walking through the gaudy and gay Miami Bayside entertainment area during the Miami Strictly Sail show last week, whilst dodging obstacles such as parrot-wielding hawkers and perfume swatch pushers, I spotted a sign promoting a bar/restaurant called “Mangoes”.
     This, reinforced recently by the sight of them on a supermarket shelf, reminded me that if I ever go back to St. Lucia, I have been promised free mangoes there for life.

How that all came about makes for quite a tale.
