Give a guy a sunny day on a boat with solar panels and some down time and he'll inevitably turn into the dreaded Amp Police. Whether you have a yacht or a power vessel, the Amp Police are known to lurk around looking for trouble as you can see by the above photo of Maynard's iridescent note book. Now ladies, don't tell me you've never heard of the Amp Police before. They walk slowly around the boat in a hunched fashion looking for voltage thieves, switching off any electrical appliance they deem unnecessary while batting off cries of indignation from their respective partners.
Maynard has meticulously quantified the power usage of all the various systems on board Vanish which, I might add, are numerous..........fancy fridges, untold number of lights, so many TV's, 3 home entertainment AV systems, 3 microwaves, not to mention a hoard of phones, computers, coffee makers, hair dryers, yes...you name it, we got it, even an iron (or two). He's found that if we combine the contents of two of the smaller fridges and put that into the larger more efficient fridges when they have the space, and if we turn off the three AV (audio visual) systems along with the direct satellite TV system when we're not using them, we can cut our electricity usage by an astounding 30% whilst suffering no degradation in life style.
This has a huge effect on the amount of time we genset. Under the new Abaco Amp Regime, we have a base load use of 350 amps a day. On a typical winter's day in the Bahamas, our solar panels put out about 150 amp hours a day at 24 volts. During the summer, we would get nearly double this figure. We have been able to cut our gensetting from 5 - 6 hours a day to approximately 3 hours a day. This works out well as it takes at least an hour to one and a half hours a day to run the watermaker and the stove/oven for cooking but the great thing about this is that even though it is a power vessel, it is a very quiet vessel at anchor with about the same amount of genset time being run now as we did on our 52 foot yacht.
There are ways around the Amp Police. Many years ago I remember a serious meeting on a sandy beach in Northern Queensland in Oz where we ladies were in a huddle discussing who amongst us were allowed to have an iron on board. Some of the irons were hidden under bunks, but all of us had one, except the lady who asked the question. Haha, she was young and innocent and hadn't learned the finer points of sailing. Live and learn.
