The Truth About Watermaker Membranes…

24 Jun

IMG_1994
…is that they’ve gotten pretty cheap.

In not-too-distant past replacing a single membrane on a small watermaker was a $600-$800 hit. Now, as with so many other things, you can go online and buy a membrane for $150-$220. And it doesn’t matter whether you’re replacing a 20-inch membrane or a 40-inch – the two most common sizes – the price is the same.

Before I go any farther, when a watermaker is performing poorly it is seldom the membrane, but the membrane is the first thing people want to blame. You must first ensure that everything else is within spec ...

New Cooling System on Perkins 4.236

16 Jun

IMG_0150
This upgrade is common to all older Perkins diesels (the Perkins 4.108 is probably the most common Perkins found on boats). Bowman, the company that made the marinizing equipment for Perkins, has re-engineered things over the years, so that instead of having a combination header tank and heat exchanger on one part of the engine, and a water jacketed exhaust on another, they combine it all into a combination header tank/heat exchanger/exhaust manifold.

These engines were originally fitted with oil coolers. Now in some cases they say you can do away with the oil cooler unless your engine is run ...

With copper-based antifouling paints just being banned in Washington state, the writing is on the wall. We’re going to have to figure out an an environmentally-friendly way to keep the critters from growing on the bottoms of our boats. That’s where BottomBot comes in.

Dan Stein, BottomBot’s CEO says, “We took our technology from the medical industry, where nanobots have long been in development. There is a family of nanobots designed to be released in the blood stream to remove plaque from the insides of your arteries. These nanobots aren’t quite ready for prime time in medicine, for safety ...

Human Arm Found Floating At Olympic Sailing Venue

26 Feb

I’ve have tended to downplay all the press about the filth in Guanabara Bay, the 2016 Olympic sailing venue. I spent a few months living aboard there, and it’s on par with many large ports around the world. Finding a dead dog wouldn’t be out of the ordinary many places in the world, especially in a tropical place where the tends to be lots of flotsam and jetsam. But this kind of takes the cake. I won’t post the photo, in case you don’t want to see such a photo, but the photo is at the end of the story, ...

Tough French Cruiser Shot, Stabbed, Bashed, and Robbed off St. Croix

22 Feb

Arc en Ciel 2(1)-240x171

The whole story is here. Either local law enforcement completely bungled this case, or the victim’s story doesn’t add up. What is a matter of fact, because there were witnesses, is that this guy, at age 70, limped his boat back into port with his femur shattered by a gunshot wound, came alongside a tugboat, then proceeded to throw winch handles and sundry objects at the side of said tugboat for 45 minutes before somebody took notice. Shiver me timbers.

After Twenty Years, Naval Academy Brings Back Celestial Navigation

18 Feb

sextant
After removing it from their standard curriculum for nearly two decades, the navy has decided that the threat of cyberterrorism, electrical pulse attacks, lightening strikes, and other potential blackouts of the GPS system warrant reinstating the age-old art. The US Coast Guard, which stripped it from their curriculum a decade ago, is following suit.

Should cruisers be taking a hint?

You can read about it in the Capital Gazette or The Washington Post

The GPS system has never been “brought down,” according to the government, but local disturbances and drop-outs are commonplace. And it’s conceivable that the system might be ...

That Sinking Feeling off the Baja Coast

3 Feb

3 on deck
It was 1991, and we were three fools fresh out of San Diego State. Brian had bought an old Catalina 30, and we spent six months fitting her out. Against my protests, Brian changed her name to Break‘n Wind, a boat name I’ve encountered several times over the years, and never liked any better.

Brian’s artist buddy painted the new name and hailing port on the transom, along with some sorry-ass blue palm trees. I asked the artist, “Isn’t break spelled B-R-E-A-K?” He’d spelled it Brake’n Wind. The paint had already semi-dried, so we ended up with one E ...

Knowing Your Boat: The thing nobody ever talks about

21 Jan

“Uh, how is the boat going to behave when that thing hits us?”

Contrary to all the focus on new boats, their features, and their performance, the captain’s knowledge and intimacy with said boat is probably more important. In fact, when it comes to heavy weather sailing, what resides in the captain’s head is probably the most important piece of safety gear aboard. What some might call “getting to know your boat” may accurately be called the most intimate relationship a human being can have with an inanimate object.

The Cliff Notes version of getting to know a boat is ...
