Sealed Battery Warning

David Gill, new owner of Tondelayo and new member here ran into an interesting situation that is relevant to us here. As a matter of fact I have 6 AGM batterys on Valkyr. I like them because you can’t spill acid out of them. I have had bad problems on a prior boat with that. However the description here and the photos David provided are very sobering. I have had 3 AGM batteries in the past that have swollen in a very limited way and went bad. We had them replaced. I have had this happen to a couple of west marines SeaVolt AGM group 27 and 31 batteries as well as one of the optima blue top spiral AGM batteries just in the last month. So this is a very reasonable heads up. Thank you David for writing this up, and submitting it with the pictures.

Hi Scott.

Here’s a bit of information that may be relevant to anyone using Sealed 12v batteries. I don’t use them on Tondelayo but anyone who does wouldn’t want this to happen while at sea.

At 0848 hrs on 12 July 2010, pumper 402 Nelson Bay attended a caravan park in Nelson Bay. On arrival they found a 12V sealed caravan battery (also called Valve Regulated Lead Acid or VRLA battery) with its sides and top markedly bulging.

Park staff had removed the battery from inside a caravan to a grassed area.

The BA team was to cool the battery with spray from a line of 38 mm hose from behind substantial cover. However, the battery slowly continued to expand. Temperature readings taken with a TIC registered 49 ºC.

As it appeared the battery could explode, a hot zone of 30 m and a 50 m exclusion zone were established. A […]

IE display problem on website fixed!

I know that a lot of people have had issues viewing the website lately. That should be fixed now. The code for the last upgrade caused a bug in IE to not display the site correctly because of a ( ” ) sign in a comment on a post. Something so simple that brought the whole site down in IE. I could really hope that Microsoft would start writing standards compliance into IE but am not going to hold my breath.

It took a while to track it down but it is up and working again thanks to the help of the theme developers that built the theme we are using on the website. I kicked them a few dollars for their help as they were gracious enough to spend some of their valuable time looking at our problem. I was pulling my hair out about it.

Thank you everyone for your patience while this was resolved. As always if you are having a problem using the site or see something that is wrong let me know and I will do my best to get it fixed.

Original Front view. with five inch long 1/2" ID Thermostat by pass hose

Existing barbs are good enough for 1/2 inch ID hose. Original Barbs in place

I ended up using a 1/2" hose on the existing barbs. The 1/2 " hose runs about three feet back to the existing 5/8" heater hoses. At that point there is a 1/2" to 5/8" plastic adaptor that makes the conversion as shown.

Plan view w/o brass elbow

I have found some brass 90 deg elbows that may fit into the pipe thread of the engine so that the “From WH” line can stay below the “to WH” line to make it easier to fill the water heater when changing coolant.  I may install them next winter, but so far everything is working OK and our continuous speed is 15% faster as we are no longer cooling system limited.

Front View w/o Brass Elbow

There is a manufacturer that specializes in marine heaters I ordered their H-406, H-417, and H-407 3/8″ Male Pipe Thread to 5/8″ inch hose adaptors, but I have not installed them yet.

Heater Craft’s, Dan Shull at 208-687-4400. or e-mail him by clicking here

Westerbeke has the straight adaptor P/N 302391.

I have not been able to get the old barbs out yet.   The system is working fine now so I may never add the brass elbows.  It is difficult to get the air out of the water heater lines, and I expect that the […]

sv Bluesky: Passage from St Helena to Salvador, Brazil, May 2010

#gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } /* see gallery_shortcode() in wp-includes/media.php */ The passage from Saint Helena to Salvador, Brazil is 1,914 nautical miles. As Blue Sky sailed away from the island a pod of dolphins bade us farewell. Fourteen days later we arrived in Baia de Salvador, Brazil! The voyage was calm and we rarely had to touch the sails. Everyday we put the trolling line out so we could enjoy a fresh fish for dinner, but had no luck, not even a bite. Becalmed for a couple of days we were forced to motor. This delighted the children as they had all the electricity they needed for DVD’s and Game Boys. Left is a photograph of a typical South Atlantic squall, fortunately they did not produce much wind, unlike the ones we encountered in the Pacific Ocean. The tall buildings dot the skyline of Salvador. This historic town was once the capital of Brazil. Begining in 1549 until the role was transferred to Rio de Janeiro in 1763. Until then the city was the second most important Portugese capitol second only to Lisbon. This was due to its huge trade in sugar and gold. There are two sections of the city, the upper or Pelourinho, which is a Unesco World Heritage sight. The historic colonial architecture dates back to the 17th and 18th centuries, built atop a cliff. You can access this area either by an elevator, built in the 1930’s or a cable car on an inclined plane. The children prefered going up on the train, but both are spectacular! Anchoring Blue Sky behind the circular Forte de Santo Antonio in the small craft harbor. The fuel dock was right next door and the men in charge lived aboard the barge. We had read that there could be petty crime in the anchorage but possibly because of our friends on the fuel barge we experienced nothing of the kind. Instead we were greeted only with kindness from everyone we met. I think our little “ambassadors” have a great deal to do with our good luck!

Exploring town there is a church on every corner, we read that there are over 365, one for each day of the year

the Greja de Sao Francisco, built in the Baroque Style in 1723, and is one of the richest temples in Salvador. The gold plated wood carvings on the altar and the fine Portuguese glazed tiles surrounding the walls are dramatic. We were lucky to arrive on a day when there were guides. It was a fantastic tour.

Above we are at the top of the elevator on the upper section of the city, looking at the circular fort and small boat harbor. Blue Sky is anchored behind the fort out-of -view.

The San Antonio light, is the first light house in the Americas. In 1839 the roatating kerosen lamp was located in a wooden tower.. In 1890 the structure you see today was installed with a 3.5m lens, this mechanism is still in use. The light was electrified in1932 and can be seen 38 miles off shore. Above: Phoebe and Drake pose at the light’s base.

For our first visit to Brazil this was a very good choice.  Checking into the country was realitivly easy.  Thankfully the dock master had all the paper work we needed and provided it to us in advance!  To do this he charged a small fee.  In my opinion it was worth every Reais!   There are small luncheonettes all around town and we managed to sample most of what Brazil could offer.  The buses were very efficient and it was easy to get to the shopping to re-load our provisions.  The people were very friendly, it was sometimes confusing to communicate, as our Spanish, although close to Portugese does not quite match up.  Even so with the patience of the some of the nicest people we have had the great fortune to meet we were able to get by.  We did get lucky at a book store and found a copy of a Portugese/English dictionary.  Each night we would work on the words that we had needed that day.  Little by little our vocabulary increased with the children being best able to absorb our new language.  Many of the children we met loved to practice their english with us and assisted us in learning new phrases and translating menus.  There is a big push for this generation of students to learn english having one hour of the school day devoted to studying english.

Dorade Vents

This was another project from a few months ago.. actually last october.. since then both cowls have been replaced with Nicro Solar vents.

The plastic cowls on Valkyr’s dorade vents had become very discolored and brittle with large chunks broken out.

As a last project before we left the boat yesterday we decided to replace the cowls on the dorade boxes. Angela who we bought the boat from had already bought a couple Nicro plastic cowls.. They were the exact same cowl as was originally installed on Valkyr so all the holes perfectly matched for the mounting screws. We thought it would take a few minutes to do this. Two hours later we actually finished. The screws holding the cowls on were all bronze with a nut on the opposite side. So we ended up taking the entire top lid off the dorade box to get to the underside. I’m very glad we did. There was really nasty stuff in the dorage boxes. Mud dobbers had been living in one years ago and left behind about a two cups of dirt that was holding moisture. The other dorade box was a cockroach motel. Shop vac to the rescue.. it sucks dirt and cockroaches equally well.

Also as you can see in the above images the wood in the cross pieces the box is attached to on deck is starting to rot out.

The design of the current opening through the deck leaves something to be desired. It is a flanged piece of pipe that is screwed to the underside of the deck and comes up through a hole cut through the deck. It only extends about an inch above deck level. It also doesn’t have any way of sealing it closed. Under most conditions it is probably […]
