Decisions: Smoked Phish or Byrned curtains?
1) it has only four strings,2) you plonk along playing only one note at a time, and 3) if you make a mistake no one notices! Perfect. The choice was made. So, now that Iβd settled on being a plonker, I needed to see some live action in order to analy...
Making the Most of Bank Charges
Charging Diodes. Many vessels have separate battery banks for the house supply, engine start, thruster, etc. Shore power chargers typically have multiple outputs, each isolated from the other so that separate banks can be charged simultaneously, but ...
Full Speed Ahead!
While perusing the promotional material published by what appears to be the sole manufacturer of marine variable speed self-contained air conditioning units, the claim of 50% energy savings leaped out at me right away. But on reading the small print,...
Beware of the Speedy Meanie!
Observing these two got me to thinking how this speed disparity relates to the variable speed compressors we have now in both refrigeration and air conditioning systems. If thereβs not much work to do, then why not slow the compressor down and run it...
On the Road Again
Interest was high, but the level of customer participation, the actual act of making a purchase, is too early to gauge. There were many βoohsβ and βahsβ for the Solara walk-on panel that we had laid flat at the foot of the steps on our display, and a...
I Think, Therefore I Am ... I think
Just imagine: a glob of air is sitting there in the sky, just enjoying life and looking at the clouds, when all of a sudden it is assaulted by a blade travelling at high speed and is split into two air masses. The lower air mass sees the wing passing...
Get used to it

Current Affairs - Making the Right Connections
For my testing I connected five brand new Group 31 batteries in parallel with equal length straps. The first set of tests was with Firefly AGMβs, followed by identical tests with RELiON lithium iron phosphate (LiFePO4) batteries, as I was curious to ...
Solar Myth Busters - Revisited
MYTH 1 - Glass solar panels with aluminum frames are the most efficient. BUST - No, no, no! The type of cell determines how efficient a solar panel is, not how it is constructed. Coastal Climate Control offers three types of panels: aluminum-framed g...
Pissing in the Harbor
The objective of the cooling water discharges on these sailboats seems to be quite the opposite to the powerboats. Now the trend appears to be to install mini cowlings over the discharge thru-hulls in order for them to be noticeable in various ways, ...

Opps My Mistake!

Shining Some Light on Lithium Battery Systems
Prismatic cells with lithium iron phosphate chemistry (LiFePO4) come in many shapes and forms, but a popular size is of around 100 amp/hours with a voltage of 3.2 volts or thereabouts, so four are required wired in series to make a nominal 12 volt 10...
Solbian Solar Panels on Hylas 54 Genevieve

Charge of the Lightweight Brigade
LiFePO4 batteries exhibit very different charge characteristics to lead-acid types. They can accept a very high charge current, and will do so for the entirety of the charge, and then effectively switch themselves off when full. You can see the diffe...
10 Steps to a Perfect Refrigerant Charge
2. Do not have someone attempt to asses refrigerant charge level by weight. These small systems contain a ridiculously small amount of refrigerant, and it is impossible to weigh in refrigerant accurately, especially if the boat is rocking. Moreover, ...
Trouble in Paradise
A capillary tube (cap tube) refrigeration system contains a very precise amount of refrigerant. There is no reservoir or holding tank for excess refrigerant, and over-charging will inevitably result in poor performance. The system will be either perf...

What a Wallop!

Flexible Solar Panels - Are They Any Good?
But what all those people are saying in effect is, unfortunately, that the flexible panels they bought were of a lesser quality than desired for marine use. At some point we all have succumb to advertising claims that make a product sound too good to...
A Re-Volting Thought
In theory, as the 12v battery is depleted it will be recharged from the traction battery, and when the traction battery gets low the built-in generator will kick in and charge it up. So, in theory if I leave the Volt switched on I could have 110v AC ...

Good Luck and Bad Luck Omens on a Boat...
Good luck and back luck omens are different on a boat than on dry land. For instance, whistling on a boat is expected to bring upon strong winds and is therefore considered bad luck. Bananas on a boat are also seen as bad luck especially on fishing boats. It is thought that fish do not bite on a hook if there are bananas close by. Finding a cat on a boat on the other hand is considered good luck, even if it is a black cat. Cats eat rats and keep the boat clean and safe.
17th Century Vessel - The Only One of it's Kind
Vasa is a Swedish warship that is known for sinking in 1628 and being recovered in 1961. After spending centuries in the water, this boat was still completely intact and in good shape. It is actually the only vessel left from the 17th century. This boat now lies in the Vasa Museum of Stockholm which was built as a tribute to this ship. It is now one of Swedenβs most popular attractions. It receives almost 30 million tourists.
Boats Have a Life Expectancy
Usually, cargo ships that sail in the oceans can have a lifespan of 20 to 30 years. Sailboats are meant to be used for 30-40 years even if they are made of softer materials such as plywood or fiberglass.Β They are not deemed safe or stable after their expectancy.
