AnswersFirst there was the abacus. Then there were slide rules (I still have one that I use as a straight edge). After that came rudimentary mechanical calculators followed by electric and then electronic versions, and now calculators have wound up being one of the most rudimentary features of computers, smart phones, watches, etc. All of the aforementioned devices require that the operator first input the correct information and then give the correct commands in order to be supplied with the desired result. Put in the wrong information and/or give an incorrect command, and the result will be erroneous. Garbage in - Garbage out.

Now imagine that someone picks up an abacus and sees that the beads are arranged to indicate the number 42. So if the answer is 42, what was the question? Was it: “What is 6 x 7”? or “What is 17.5 x (9.8 - 7.4)”? or … Hmm. Maybe 42 is the answer to the ultimate question of life, the universe, and everything.

There are the typical ones such as the sign in the warehouse toilet saying “Gentlemen please lower seat when finished”, and then there are unwritten words of wisdom like; ”If you have it, flaunt it”. Personally I’m a bit lacking in flauntable assets, but Coastal sells some of the best specialized marine equipment available, and we flaunt it whenever possible. In fact, next week we will be in very flaunty mood at the Annapolis Spring Sailboat Show April 20 thru 22, so if you’re in town come on by and see what’s new.

Another unwritten house rule is: “If we don’t have it, we can’t sell it”. It seems obvious I know, but keeping adequate stock of popular items is becoming a bit of a problem these days, especially for products that we import. We strive to be good girls and boys and pay our bills on time and plan way ahead in order to anticipate shipping delays, but we still often get caught out, and increasingly so these days. There are three main areas that we have no control over:

Just imagine having the capability and resources to do that, and the mind boggles at the thought of what else you could dispose of up there in the big blue yonder. I presume that he removed the battery before take-off, because those things are heavy.

Yes, I know they are Lithium Ion (LI) batteries, but those are not as light as some imagine. I know this from when I drive my Chevy Volt to my office in Tesla Drive (a bit ironic don’t you think) and feel how solid and sure-footed it is on the highway. That’s because it weighs about 800 pounds more than a similarly sized Chevy Cruze due to the hefty battery pack. But thanks to that 17kw lump, I have sizzling, silent acceleration and decent range in a very stable platform.

Talk is that there’s soon to be an Electric GT motor racing series featuring a modified Tesla. This will no doubt have phenomenal out-of-the-box performance, but weighs in at about 200 pounds more than my road-going Volt, and where less weight = more speed (i.e. on the race track) that means a lot of lithium to be grappling with lurching around the bendy bits.

I started tinkering with LI batteries six years ago, and even made my own 100 amp/hr pack from bits and bobs I bought online. I did it primarily to investigate whether that might be a viable alternative to the few expensive and complex marine LI systems available back then, but soon realized that the safety aspect was paramount.

Those specialized marine LI systems featured external Battery Management Systems (BMS) that could cut loads and/or charging devices if anything got slightly out of whack, and when you’re in the middle of an ocean that’s a pretty important feature. Most of the online offerings I came across were for auto use, where it’s assumed that if something goes wrong you can pull over to side of the road, hop out, and run away. Not so good for a yacht where the closest land may be a just mile away, but happens to be straight down, on the ocean floor.

Dover, England. A fascinating place. I was there recently meeting with a friend who keeps a sailboat in the marina, and he showed me around the ongoing construction project that will one day be a spanking new marina complex plus more desperately-needed parking spaces for lorries (trucks) waiting to embark to Europe on ferries. I also happened across the huge Banksy street art that appeared overnight recently on the end wall of a building near the docks. This features a star being chiseled off the European flag, a satirical comment on Brexit for the amusement of those heading to the ferries over to Europe.

There’s enough history in Dover, both ancient and recent, to satisfy all manner of inquiring minds. Being at the closest point in England to Europe it has proved to be an enticing location for a water-borne invasion through the ages, so it’s only natural that various means of defense have been constructed to repel attacks. The town itself is at sea level, but at its eastern and western extremes it is under the shadow of the higher elevations of the famous White Cliffs of Dover. The cliffs are sans bluebirds these days, as that was the nickname given to wartime fighter pilots in their blue uniforms. Perched menacingly on top of the eastern cliff is one of the most imposing and magnificent castles to be found anywhere; Dover Castle.
