I Think, Therefore I Am ... I think

I’ve been thinking about a lot of things lately. I don’t know why, maybe it was the winter blues bringing on a bout of the melancholies. In particular, I’m often fascinated with things that just seem to happen, but without any obvious visible clues as to why or how. Take the theory of flight, for example.
I was on a ‘plane recently, and got to thinking about the whole theory of lift and flight. We are taught that air flows over the wing and bla bla bla. But air doesn’t actually flow over the wing, now does it? No, it’s the wing that slices through the air.
10 Signs it’s Time to Replace Your Boat’s Refrigeration

1. Box no longer reaches desired temperature set point
A refrigerator box should be kept at 35-40F for safe food storage.

2. System works sometimes OK, sometimes not
You can bet your bottom paint that everything will be hunky-dory for month after month, and that the gremlins will strike on the first day of your annual cruise with all the family on board. Time to get proactive and get the fridge fairies on your side with a nice new, shiny ,reliable, fridge system.

Right away, let’s quell the myth that By-Pass Diodes are there primarily to improve performance under shaded conditions.
Solar Myth Busters - Revisited

We had another highly successful show in Miami this year, with a lot of interest in our solar offerings, but we still find it necessary to spend considerable time with interested parties having to explain the what’s what of solar power for boats. Evidently there is still a lot of misinformation out there on the subject, so this seems like a good time to re-hash one of our most popular blogs from many moons ago. Here follows a list of ten myths and busts in an effort to set the record straight.
