Birthday II

The blog has turned two, which in boat years is about 99. The year started out with a bang, and a lesson. The first story of the second year was 120 Seconds, and it got a lot of attention on the forums. The lesson learned is that attempting to defend yourself in the wild west of Internet forum land is often like pouring gasoline on a fire. I now rarely comment, and my skin is much thicker.

The no wire pull zone

You are traveling through another bad dimension, a dimension of not only frustration and ire, but of mind. A journey into a horrific land whose boundaries are that of poor workmanship. That's a signpost ahead, your next stop, the "No Wire Pull Zone".

It's a hot day, and the air is as still as death. The wire fish slides effortlessly through the small hole and heads up the pipe, and then stops with a clink. The installer wipes the sweat from his brow, backs the fish off a bit, and tries again. Clink, and again clink. A flash of fear crosses the installers face as he nervously tries again and again to push the wire fish into the abyss. Clink, clink, clink, clink, clink. The installers sense of foreboding, builds to a peak and he screams in terror, for he now knows he has entered the "No Wire Pull Zone".

The 2011 NMEA conference

This was the first time I had been to a NMEA conference, and I was there because I had been given the honor of being one of the three judges that would decide what new marine electronics product would be awarded the 2011 NMEA Industry Technology Award. Below are fellow judges Tim Queeney, (front) editor of Ocean Navigator magazine, and Ben Ellison, (back) Bonnier's electronics editor most notably Yachting, and Cruising World magazines, and publisher of, Panbo, The Marine Electronics Weblog. This was most august company indeed for this humble installer to work with.

Hole in none

Once upon a time a good local electronics repairman could fix your marine gear. Manuals had pages of circuit diagrams in the back of them. Of course then, TV's were black and white, and you could take the tubes out of them and test them. The trade off was the gear was very large, and was full of antique transistors, capacitors, crystals and the ilk. There are still a few of these specialized technicians around, but nowadays most marine electronics are repaired by replacing the bad board, or more often warranty repairs are done by replacing the entire unit, lock stock and barrel. The huge hole you see below had a VHF radio in it that has now joined those who are dearly departed.

NEMA, oops I mean NMEA

Language is a wonderful and changeable thing.  Acronyms, and our attempts to pronounce them can bring about decidedly weird effects, so today we are discussing the National Marine Electronics Association, or in its acronym form NMEA. This is not to be confused with NEMA, the National Electrical Manufacturers Association, the National Emergency Management Association, or even the New England Multihull Association.

Somehow over linguistic time, the acronym NMEA has ended up being universally pronounced, such as acronyms can ever be pronounced, as Nee ma. This verbal utterance has become so pervasive, that the marine populous, has actually changed the spelling of the acronym NMEA to NEMA to reflect how we actually say the acronym. If you search "NEMA 0183" -NMEA, Google finds over 24,000 references. I did some snipping off the web of examples, and noted that even the Installer himself has screwed this up at times, and boy I'm not alone. I have purposely not changed it as a personal reminder to myself. 

The rate of change from NMEA, to NEMA has been increasing rapidly over time. There are a few references in the eighties, even more in the nineties, and in this decade using NEMA in place of NMEA is almost common place.

So there are are three options available, do nothing, and continue to pronounce NMEA as Knee ma, change the name of the National Marine Electronics Association to the National  Electronics Marine Association, or change the way we pronounce it to "NA Me Ah.  My vote is to be diligent about spelling it correctly, and to continue to pronounce it Knee ma, or Knee maw if you live in the south. Tomato, tomahto, potato, potahto. Nmea, (it is a word, sort of) that is a cool electronics network on your boat bro.

By the way this was all triggered by attending the NMEA conference on Sanibel Island (almost). I am just about done with the piece.

Palm Beach Florida, a travel log.

Kate and I took a road trip this weekend to visit her brother Mathew, and his wife Robin who were vacationing in Palm Beach Florida. Mapquest routed us across the state on primarily picturesque, and rural two lane roads across old Florida crossing just above Lake Okeechobee.

Ripped out, ripped off, and other meanderings

Yep it's gone. About the only thing you can say about this install is whoever did it apparently couldn't read, because the directions tell you not to use the sealants they did, and at least two types were used. The second layer was smeared on no doubt to stop the leaks found after the first layer was glopped on with a precision that could only have only been done by a drunk organ grinder's monkey, or maybe just a drunk organ grinder. And I don't even want to know what that disgusting black stuff was in the lower corner. Okay, I won't contest the fact that this is the only place on this boat for a in-hull transducer to be mounted, and that it is damnably difficult to access. So what makes this so irritating, is the previous owner ripped it out before he sold the boat, thus ripping off the new owner.

The excavation, it's all your fault

Yuck, it was disgusting, and time to get the rubber gloves out. A half eaten bag of chips, old rusty fishing hooks, a foil pack of Trojan eye glass wipes, mildewed papers, and a leaking bottle of suntan lotion giving everything a lubricious sheen. The sad reality of this eclectic collection of sea going goods, is they will end up on the deck when I drop the hatch fully down. Just to make it more visually interesting for me, it will start to ooze some suntan lotion mixed with assorted detritus onto the deck.

The "Yogattorney" and the Kerala houseboats of India.

Nancy, is a yogattorney. Yes it's spelled right, sort of, because she is both an attorney, and a Iyengar yoga instructer. The yogattorney makes frequent trips to India, and on her last trip, she had the opportunity to take a trip on one of the famous Kerala house boats from Cochin to Kovalam Beach in the Indian state of Kerala. So playing the game of "Where in the world is Nancy?", I have constructed a little map to show you where Kerala is.

The state of Kerala, is located on the very southwestern coast of India facing the Arabian sea. It's bounded to the east by the Western Ghats mountain range, and then transitions to low coastal plains, and the Kerala backwaters areas on the coast. The climate is tropical and it lies just north of the equator (8 to 12 degrees north latitude). Millions of tourists are drawn to Kerala for its lush tropical backwaters, biodiversity, and 370 miles of beaches.

The houseboat Nancy traveled on is in the local parlance a kettuvallam, an ancient form of watercraft that has been plying India's waters for centuries. The kettuvallam is historically a double ended cargo vessel used to transport goods such as rice, and spices up and down the coasts, and into the more remote backwaters. They are by design shallow draft, and can also be poled when needed.

With the advent of the modern world, the automobile, the backwater areas became crisscrossed with roads, and bridges that steadily reduced the areas the kettuvallams could access. This coupled with less expensive transport of goods by truck made shipping by kettuvallam less viable. Over time the numbers of larger kettuvallams, especially the sailing versions were dwindling away, and more importantly the pool of skilled artisans who knew how to build these vessels were diminishing with them.

What's so fascinating about these very graceful, and elegant watercraft is that they can be upwards of 100' long, and they are literally tied together, hull and all, using a rope made from coconut husks. These boats are completely made of local indigenous raw materials, using simple hand tools, and techniques that have been used to build them for over two thousand years.

In the late eighties Babu Varghese, an Indian entrepreneur and tour operator spearheaded an effort to take the traditional kettuvallam, and transform it into a houseboat suitable for ecotourism, and at the same time reviving the art of building them. The first "Kerala house boat" was launched in 1991, and ever since this specialized floating tour business has flourished, with hundreds of these vessels built, and directly, and indirectly employing thousands of workers.

Despite the simple tools, and lack of mechanized boat building technologies, the Kerala kettuvallam houseboats are beautifully executed, and finished. They have all of the amenities one would expect to find on a modern boat, but with a traditional, and hand crafted elegance, that comes through the clever, and skillful use of all natural materials. Unlike the original kettuvallams, most of these house boat versions are now engine powered, and still, in many cases often oar steered. In some locations in the backwaters, poling is required to maneuver in some areas.

The Kettuvallam's primary building materials, are all local, and sustainable consisting of white coir rope, and brown coir (both from coconut husks), bamboo, anjili wood for the hulls, palm leaf thatching, and a caustic water proofing oil derived from boiling cashew shells. With these few simple materials, a gorgeous boat is built.

Coir rope is made by soaking the husks from immature coconuts (white coir) for many months in a process called water retting uses micro-organisms to dissolve the plant matter around the fibers. The remaining husks are then beaten to loosen the fibers which are separated by hand. The fibers are spun into a yarn used make rope typically with the aid of a spinning wheel.

The mature coconut husks (brown coir) are treated in a similar way, but it does not require the very long retting periods of the white coir. Brown coir is used for floor mats mattress stuffing, and other utility purposes. Coir is relatively waterproof, and is one of the few natural fibers that is resistant to damage by salt water, making it ideal for boat building use.

The word "Kettuvallam" comes from the Malayalam word kettu, meaning to tie, and vallam, meaning boat, and hence the literal meaning "tied boat".

The unique aspect of kettuvallam construction is the hull planks are physically tied together. Planks are spiled, and shaped just like all wooden boat builders have done for centuries, but the difference here is the hull planks have holes drilled in them at the edges allowing them to be stiched together. Larger vessels have plank edges cut in a tongue and groove shape to provide additional interlocking strength to the joints.

White coir rope is used to lash the planks together encapsulating a bundle of brown coir that is being hammered to reduce its volume as the coir rope is being tightened. The brown coir acts as the hull plank crack filler, and serves the same role oakum does in traditional western boat building.

The stitched seams (kettu) are then coated with a paste of charcoal powder, lime, and fish oil for water proofing, and the hull is then over coated with cashew nut shell oil/resin, and charcoal powder. The charcoal powder gives the hull its distinctive black color, and the caustic cashew resin coating makes the hull resistant to wood boring molluscs. There are regional variations in the recipes of these natural coatings that vary somewhat from builder to builder.

The vessel you see being tied in the photo above is a smaller kettuvalam referred to locally as a "1/3 load" kettuvallam, that is used for mud collecting, sand mining and the ilk. (See the link to Dr. Ransley's project synopsis below to see how important this function is).

The end result of all of this activity is a hull that is fair, strong, and very durable. Kettuvallam house boats typically have substantial spine planks (keel), stems (fore and aft), and gunwales.

In the photograph, you can see the gunwales are made of scarfed planks that have been secured with large copper rivets, and or roves. The same system is being used to secure the primary framing structures to the inside of the hulls. We are looking at the sterns of both boats. I think I see a drive shaft hole on the left kettuvallam, and I can clearly see it on the right one.

The finished hull gets decked, and a curvaceous frame of split bamboo is tied together with coir rope to make the superstructure. Thatched/woven palm leaves are tied onto the frame, and additional split bamboo frames are again lashed over the structure.

Although the superstructure appears to be flimsy, you can see in the photo there are now three people now sitting on the partially finished work. When completed the structure will be very strong and waterproof. Interiors are finished with locally available natural materials, fabrics, and carpets. In the end, it's striking how such graceful, durable, and watertight vessels can be constructed out of such very basic materials, and with so little modern boat building technology being utilized. These vessels are truly testaments to the skills of their artisans and a time proven design.

I want to leave this little vignette with this photograph and a few thoughts that struck me about this smaller kettuvallam. The first is that if you rolled the clock back a thousand years, the ancestor of this boat would likely be very similar to this one.

Looking closely at the construction details as a boat builder myself, I recognize many of the construction elements and I believe much of today's modern wood boat building techniques owe their beginnings to this ageless craft, and the many generations of talented artisans who have crafted them. Although this boat building approach has been used in India for many centuries, we didn't get around to adopting it until 1964. We were a little slow out of the gate.

Boating yin and yang

We're starting in the happy place today. June Cleaver is baking a fresh apple pie, the Beaver is doing his homework, little Opie Taylor is fishing down at the pond, and the sun is shinning. I have to re-install a VHF antenna, and an older Raystar 120 GPS antenna. Brand new T-top canvas has just been installed, and I had to untie a portion of it to see where the old equipment holes were located. Lo and behold, look at that hole, it's a beauty. Two inches in diameter, and someone took a moment to deburr the edges. How sweet it is, this is the way it's supposed to be done, and my hats off to the builder of this T-top.

When hurricanes collide, the Apocalypse

The meteorologists at the Parmain secret labs have been studying the latest NOAA weather data, and using our advanced Commodore Pet computer have modeled the latest lasgana tracks for both Lee and Katia. Our expert opinion is that these two storms will collide together right over Washington DC. We understand that Congress, in a rare bipartisan move has agreed that any sighting of the Weather Channel's Jim "Dr. Doom" Cantore checking into any 5 star hotel in the area will be the signal to immediately get out of town. Funds have been allocated to charter private Gulfstream G550 corporate jets for this purpose. Congressional staffers will be given a $75.00 travel voucher, for bus fare to Topeka. Some scientists have theorized that when the two storms meet, that it is possible that a black hole could be formed, or the state of Maryland could wash out to sea.

What's that job?

"Welcome everyone! I'm your host Larry Hokem, and this is What's that job, the game show in which contestants try to guess what job is being done. We have selected the first three players that could correctly spell the word boat, and now let's meet them."

Steps, and second steering stations on smaller boats, nope, don't like them

All too often advances in technology or performance comes with a price, and a step hull is no exception. Step hulls are much different from the deep V hulls most are familiar with, and come with their own special jargon that contains words such as chine walking, snapping, rolling, hooking, step tripping, porpoising, turn blow outs, and many others, none of which have successful boating connotations. The point is that all boat hulls are compromises, and step hull vessels have more of them than most, particularly for the less than experienced boater.

Knocked up

This is a common sight in many marinas. The "Steel Forks" of the lift snatch your boat out of the water, and place it onto a storage rack, or the ilk. The forks always end up generally in the same place, sort of, and that is the outboard edges of the hull, give or take. Running these machines takes practice, hopefully not too much on your boat, and a lot of skill. There are always signs around dry storage marinas that say something to the tune of, "Make sure your antennas are lowered, and the trim tabs are all the way up." Loosely translated, this means it ain't our fault if you end up with broken, or bent stuff on your boat, or any of the other possible variants such as "Tell it to the judge", "We told you so", and my favorite, "What, you can't read? So given the fact that these huge metal hydraulically operated prongs are going to snatch your boat from its undersides, why would you mount your transducer where the forks can knock them up?

Why didn't I think of that? Outboard lower unit salvation.

I have always wondered why, at some subliminal level, when you tip back a modern outboard motor, a little bit of the lower unit always remains in the water. Maybe the reason for this is to insure that one of the most vulnerable portions of the motor stays in contact with the salt water to insure galvanic corrosion will occur, and hence new parts will be needed. Or maybe there are unknown mechanical reasons why the motor can't be lifted that last six inches or so to clear the water. I mean we went to the moon didn't we? So I was most surprised when I encountered two boats next to each other, one with this nifty little box under the lower units, and one without the little box.

Cooking with the "Splendid Galley"

The trick to good marine cooking is great ingredients, and lots of patience. Today's simple recipes feature a gorgeous roasted batteries au jus, with a tasty side dish of blackened air conditioning controller. You will find the spicy crunchiness of the blackened controller will harmonize beautifully with the savory acidic flavors of well cooked plump batteries. The mouth, and eye watering aroma while cooking is indescribably exquisite. I can hear your tummy growling in anticipation already. This recipe will feed a good sized crowd, so be sure to size the recipe proportions to fit your needs.

Ingredients:

2 Plump 8D batteries (I like to squeeze the sides to make sure they're firm.)

1 Heavy duty battery charger.

1 Air conditioning system (the best ones are mounted high up on a bridge)

1 Undersized water hose to air conditioning system.

1 Galvanized iron pipe nipple
Salt and pepper to taste
Serve on a bed of lettuce for a little extra panache. 

Cheesy boat, the movie

String theory

In the beginning God created the heaven and earth. And the earth was without form, or void, and darkness was upon the face of the deep. "Um Dad? can I ask you a question?" "Make it quick son, can't you see I'm busy?" "I know, but are you going to leave all of those quantum strings you're using just laying around for the inhabitants to find?" "Don't worry son, when they find them, and figure out how to use them, I will just get really far away. I don't need the tan." Now go back, and keep practicing on Pluto, it looks like a potato for gosh sakes. Let me be. I barely have a week to get the job done, and this photon stuff is very tricky, but if you're good, we can play Asteroids when I'm done." "Thanks dad."

Aluminum animus

Bronze has been around, well at least since the start of the bronze age, about 3000 BCE. As a matter of fact, the first use of metals starts with gold around 6000 BCE, and by the time Jesus appears, there are only seven known metals in the world. Their appearance in history starts with gold, then copper, silver, lead, tin, iron, and mercury. Aluminum however was first made in a crude form in 1825, and really wasn't a viable commercial metal until the late 1800's. It's a marvelous material when used in the right place for the right reasons. But I would opine that dash panels are not a good long term use for this material, especially when exposed to the salt water environment. 

In the real world, or at least in my version of it, I know why it's used, and that's because you can make it pretty, much to the delight of the marketing departments. From this installers viewpoint, the stuff is a real pain in the ass to deal with.

Ships log, the North Channel

July 29th

Pulled into the Bad River anchorage last evening, and this morning was eventful. Little Johnny said there was water on the floor of his cabin, and there was. The seawater hose for the toilet had cracked. I used a piece from the garden hose to fix it, and pumped the water out. The only causality was all of the canned goods were stored below, and all of the labels came off. A couple of those sailbote guys came rowing over, and complained about the Coleman generator on the swim platform running all night. What was I supposed to do? The kids wanted to watch movies, and Joan wanted the AC on. What a whiny lot. The place is nice, but you can't get a TV signal at all. Sent the kids ashore to dump the garbage some place, pumped the holding tank out, and we headed for Killarney.

It's one thing after another, it's a boat.

A friend of mine recently bought a late model outboard motor that was attached to a free older center console boat. On the whole it was a very good buy, but the previous owner was somewhat cack handed at repairs, if they were made at all. The boat hull was buffed back into shape, and out it goes for an inaugural trip which results in a near sinking in some rowdy water. As the vessels stern compartment was filling with water it was observed that the bilge pump was not functional, but with some luck they made it back to the boat ramp. After waiting for half an hour for the water to drain out, home they went. I came over to look, and to listen to the story. Everything was fine in the beginning, but it was getting rough by the time they noticed the lowered back end and returned
