OUR PURPOSE
We empower BOATERS with the tools, inspiration and know-how to get the job DONE!
Something's Bugging Me
In my first season running a sailboat in The Caribbean I was faced with the dilemma of an approaching hurricane out in The Atlantic. It was September after all, so not unexpected, and it was forecast to eventually veer northwards and again not bother...
Frozen Dreams
For those of you snowbirds currently basking in warmth and lathered up with sunblock, this will serve to reinforce the notion that you shouldn’t start heading north anytime soon. In the years leading up to 2019 BC (Before Covid), boats would be sold ...
10 Signs it’s Time to Replace Your Boat’s Refrigeration
3. It’s using too much energy The older DC powered systems using the Danfoss BD3.0 and earlier compressors (or even the humungous, clunky holding plate systems that pre-date the 12v revolution) were great in their day, but their day has passed. Syste...
Holiday Spirit
If past years are anything to go by, this office will soon be awash with requests to supply parts and organize repairs to systems on moving-targets of vessels that are flitting from island to island day by day. Our efforts will no doubt be exacerbate...
RIP Holding Plates
Holding plates are basically a tank containing a solution that is designed to thaw at a particular temperature. Included also is a coil of tubing through which a refrigerant circulates at very low temperatures when the refrigeration system is running...
Get used to it
When backing up I’m nonchalantly expecting a radar device to start beeping if I get too close to anything, a luxury that’s usually non-existent in the level of rental car I’m lumbered with. The first sounds of contact I’d hear would be the scrunch of...
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, ...
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 ...
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...
Magnetic Personalities
Outwardly, the only sign of anything untoward was a small blister in the top foil, but an autopsy revealed a connecting track beneath the blister reduced to cinders, and two tiny zap holes in the aluminum backing plate. Where the lightning went from ...
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 there’s not much work to do, then why not slow the compressor down and run it...
Mummy, the batteries have melted!
Apart from greatly reducing their life-span, storing and/or cycling batteries in elevated temperatures can greatly enhance the possibility of a thermal runaway situation in AGM batteries, as can using incorrect charging parameters. But thermal runawa...
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, ...
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 ...
Time is Now for Lithium Batteries on Your Boat
Lithium batteries have far more useable capacity than lead acid; charge much, much faster; offer better support for heavy loads; are about half the weight; and have a cycle life many times that of lead acid equivalents; to name just a few attributes....
Solbian Solar Panels on Hylas 54 Genevieve
So, we had a curved frame of stainless rail welded to the top of the Simpson Davits which matches the existing Hylas rails. Over that is a GRP [fiberglass] panel color matched to deck GRP to act as structure to attach the semi flexible solar panels (...
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 I’d settled on being a plonker, I needed to see some live action in order to analy...
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,...
Air Conditioning + Your boat + Batteries = Great Summer!
Any air conditioning unit can run from lead-acid or lithium batteries through an inverter. The issue is whether this is practical and economical considering batteries will need to be recharged at some point. For overnight use in sleeping cabins, wher...
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...
A Good Whacking
The Frigoboat Keel Cooler refrigeration system is a case in point. The actual Keel Cooler component is a condenser/heat exchanger that is the external component of a thru-hull fitting and is mounted on the exterior of the boat, under water, and is de...
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 AGM’s, followed by identical tests with RELiON lithium iron phosphate (LiFePO4) batteries, as I was curious to ...
Hurry Up and Wait
And that is what I got, a long wait, only realizing the joke when the sniggering reached a level that triggered my suspicions. Another long wait back then was at Easter each year preparing to launch for the yacht club’s first dinghy races of the year...
Start 'Em Up!
Part 1 Electrical motors powered from single phase alternating current (AC) have one big dilemma, and it’s because the current is alternating between positive and negative. If no provision is made to encourage it to do otherwise, the rotor of the mot...

A Burning Desire to Help
On one such occasion the tranquility was interrupted by the sound of emergency vehicles; mainly fire trucks judging by the sirens. Something was afoot close by, and human nature being what it is, I searched the internet for a means to listen in to th...
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...
My Mate Chris

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...
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 “oohs” and “ahs” for the Solara walk-on panel that we had laid flat at the foot of the steps on our display, and a...
Well Blow Me Down!
This bit may be a tad difficult to comprehend, but whereas the heat that the evaporator removes from a fridge or freezer is very cold, that very same heat magically transforms to become very warm at the condenser. That’s why I love this stuff ...
Won't Get Cooled Again
This article will focus on small air-conditioning systems that are suitable for sleeping cabins or for small boat applications. With a small air conditioning unit, the DC current draw is low enough that they can usually be powered by an engine altern...

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...
Air It Up!

Off to the Moon? Don’t forget the Sextant!
In the lead-up to the Apollo 11 moon landings, the Apollo 8 mission has been described as the most dangerous while carrying the most risks of the unknown. Apollo 8’s mission was to get to the moon, orbit it ten times, and return the astronauts safely...
Gauge Talk
The following refers specifically to MarinAire products, but the principles apply to all marine air conditioning units. There are two actual gauges; one connected to the high pressure side of the compressor, and one to the low pressure side, and they...
What a Wallop!
So that’s that. Until further notice, Coastal Climate Control will no longer be offering Solara Standard Series panels, from 12 watt through 80 watt. It’s a shame really. We only saw a small return on these small panels as they were quite expensive t...
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...
High From Amsterdam
I wish flights could be quicker though, but there is no supersonic service any more now that Concorde has been mothballed, and Coastal Climate Control couldn’t afford that luxury anyway. So, we’re stuck with flying commercial airlines at subsonic spe...
Opps My Mistake!
Back in 1999, after a journey lasting 10 months, the $125m Mars Climate Orbiter which, as its name implied was supposed to orbit the red planet and gather climate and other information, was seen to venture a little too close to the planet surface for...

There were all sorts of strange war-related artifacts left around after the second world war in the area of south east England where I grew up. This was in southeastern Kent, which was given the nickname of Hellfire Corner due to its proximity to the...
Love Hertz
Typically, onboard generators are synchronous devices. In other words, they must run at a fixed speed to be able to maintain the correct frequency of alternating current (AC). That’s 60 Hertz (Hz), or cycles per second, in North America, and 50 Hz in...

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 Sweden’s 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. They are not deemed safe or stable after their expectancy.
