ELECTRIC PROPULSION GOES MAINSTREAM

It did not take long for West Marine to see the future. 

Sorry West Marine. Been there, done that:

I've been very happy with my ASMO MARINE Thoosa 9000 system which I installed in 2008. Still it's good to see marine electric propulsion systems start to appear in stores like West Marine. Many of us who made the switch are never going back to diesel. Others will follow in our wake. No pun intended.Because electric propulsion systems are easily upgradable everyone will benefit from an increased users and improved technology especially in the battery area. Having the world's first electrically propelled Nonsuch 30 it's such a pleasure to open the hatch to where the diesel use to reside and just have the smell of clean and not oil and diesel. It's also nice to enjoy a quiet conversation in the cockpit as you motor out of the harbor. Perhaps others will now start to enjoy the same pleasant experiences.


 

BONDING AND ANTI-BONDING WITH YOUR BOAT

One day I was down below checking the mast area and noticed some water dripping off one of the bolts that held the deck mast collar to the partner area. This is not good. So I figured it was time to re bed the mast collar. Since water was leaking from the deck. The photo below shows the  mast collar as it is installed on the deck.

I was not looking forward to this because the scuttle butt was that this collar was bedded at the factory with 3M 5200 adhesive. This is known as an especially tenacious adhesive. People often say once you use 5200 on something consider it permanently attached to your boat. I had owned BIANKA for over ten years at this point and as far as I knew the mast collar had never been removed. So I was expecting a real battle in getting the metal collar removed from the deck.

I removed all the bolts and took out a mallet, heat gun and chisel expecting to spend a lot of time trying to remove the collar. Much to my surprise the collar just lifted off with a simple hand pull. So it goes! No wonder it had been leaking as the bond between the 5200 and the cast aluminum collar was virtually non existent. I also found the the remaining 5200 was still very pliant after all these years as shown below:

This pulled off rather easily too. There was some of the adhesive that need to be cleaned up however. For this I used a product called Anti-Bond 2015 . It really helps in removing and cleaning up adhesives like 5200. I just sprayed it on the area I where I wanted to remove the adhesive and let it sit for a bit. Then I used a Proprep detail scraper to peel the remaining 5200 from the area.

In a few minutes I had the whole collar area cleaned and ready for a new coat of 5200 for re bedding the mast collar. A quick wipe down with a little solvent on a rag to remove any of the residue remaining. I also did the same for the underside of the metal mast collar.

BEFORE

AND AFTER

Now that it is time to re bed I wanted to make sure I would avoid getting any of the 5200 on the bolts as I insert them. I want to be able to remove them easily in the future. NOTE: I do put a dab under the bolt head to seal it where it rests on the mast collar.  I made circles around the bolt holes with 5200. This would allow me to insert the bolts cleanly back into the holes without getting the 5200 on the threads. But would also make sure the bolts were sealed when the collar was put back on the deck. As shown below:

NOTE: You can also see the blue 3M masking tape that I installed around the outside of the collar before I removed it. It helps make it easier to clean up any of the 5200 that squeezes out from under the collar. I also put 5200 on the underside of the mast collar in a continuous heavy bead again avoiding getting it into the bolt holes. I then placed shims on the deck and rested the collar on them so that it was slightly raised off the deck. This allows me to place the bolts in the holes without getting 5200 on the threads as I insert them:

After the bolts were installed and the shims removed the collar was laying on the deck. I applied a little pressure to set the collar. But, because 5200 takes a number of days to fully cure. I waited a week before I tightened the bolts down to secure the collar. The collar was re bedded three years ago and has not leaked since. Hopefully, it will be another twenty years before I have to do it again.

GOODNIGHT LORAN C

Some news you need to use:

"The Coast Guard strongly urges mariners currently using LORAN-C for navigation to shift to a GPS navigation system and become familiar with its operation as soon as possible. Mariners will not be able to rely upon LORAN-C for navigation as of Feb. 8, 2010."

"*** Special Notice Regarding LORAN Closure: *** In accordance with the DHS Appropriations Act, the U.S. Coast Guard will terminate the transmission of all U.S. LORAN-C signals effective 2000Z 08 Feb 2010. At that time, the U.S. LORAN-C signal will be unusable and permanently discontinued. This termination does not affect U.S. participation in the Russian American or Canadian LORAN-C chains. U.S. participation in these chains will continue temporarily in accordance with international agreements. You may read more and download pertinent documents via our LORAN-C page."

Todays the day when the Coast Guard shuts down most of the Loran transmitters around the country.

When I bought BIANKA in 1995 it had a KINGS 8001 Loran unit already installed.

It took a season or two for me to really appreciate it's usefulness. It was pretty reliable but, somehow occassionaly failed just when I needed it most. I viewed it as just another tool that I could use when sailing. But, it was so useful that I did feel the need to get a GPS unit for the boat until 2008. It's interesting to ponder how many lives were saved and how many safe passages were made thanks to all the people in the Coast Guard operating the Loran C stations that were often located hundreds of miles from the sea.

Then there are all the engineers and people who put the Loran units together in companies like King Radio. Started by an engineer named Ed King. He was a private pilot in the 1950's who thought the units he could by for his plane were too expensive and did not fit his needs. So he designed his own and started a company. Roger McGuinn yes that Roger McGuinn of the Byrds fame posted the story of Ed King and his company. This quote by Ed King I think shows why he was succesful:
"If you have highly innovative, reliable products at competitive prices, a lot of your marketing problems are solved."
I'd say that's good advice for anyone thinking about starting a business.

So it is the end of another era. The end of the history of a technology designed to help use sailors keep away from danger. But, it was not just the technology but, the unkown people behind it that kept those signals beaming out.

"COAST GUARD PERSONNEL HAVE STAFFED AND OPERATED LORAN SINCE 1943. SINCE THAT TIME, LORAN HAS GONE THROUGH SEVERAL CHANGES WITH INCREDIBLE ACCURACY AND WITH NEAR ZERO LOST TIME. THE LORAN SYSTEM SUPERBLY SUPPORTED NAVIGATION AND POSITIONING NEEDS FOR MANY YEARS, AND HAS BEEN A FOUNDATIONAL ELEMENT OF THE COAST GUARDS LONG AND PROUD HISTORY. THANK YOU ALL FOR YOUR CONTINUED PROFESSIONALISM AND DEDICATION TO THE LORAN PROGRAM AND THE COAST GUARD. -Master Chief Charles W. Bowen"


Good night Loran and thank you.

SOMETHING YOU DON'T KNEAD ON A BOAT

It's been too cold and snowy to spend too much time working on the boat this winter. So I'm spending a lot of time at home in the kitchen cooking and perfecting recipes that I can use on board when cruising next season on BIANKA. I must admit I am rather spoiled using the bread maker and having fresh bread at home everyday. Unfortuntely, the breadmaker uses too much power and takes too long to be useful on board my boat. But, I came across this book Healthy Bread in Five Minutes a Day by Jeff Hertzberg and Zoe Francis which shows how to make fresh bread dough in about five minutes using a technique that looks like it would be perfect to use on a boat especially since it makes enough for four one pound loafs. That's enough for a whole week of cruising. I especially like that you don't have to knead the bread and basically make it in a plastic container. Sounds like it's made for a lazy sailor who likes to eat well and healthy if possible. Take a look at the technique in this video and see if you agree:

Why I don't sail here in winter

First saw this a few days ago on Craft a Craft. It's a video on Kontain.com. It's a time lapse of the recovery of U.S. Air Flight 1549 which crash landed in the Hudson River in New York City a little over a year ago. What I found interesting is that because of the ice you can really see the current and tidal change of the Hudson River which is a force the prudent sailor uses to his advantage. It also shows the power of ice and currents as it jostles and moves the airliner as it hits the tail. It also dramatically shows why I don't have a desire to sail these waters in winter.

A DIFFERENT KIND OF FISHING

>BIANKA having an electric motor for auxiliary propulsion uses various forms of wiring run to various locations on board. In fact there are a few wires left over from the old diesel days that still need to be removed or reassigned to other duties. Then there are other projects requiring new wires. Like installing a new 12 volt receptacle in the galley area. Which I need to do so I can use the Braun mixer/chopper in the galley location instead of moving it and the 200 watt inverter that powers it to some other location on the boat to use it.

Running new wires behind walls or bulkheads is called fishing. Which is not the same as dropping a line over the side in the hopes of catching dinner. But, it can use a similar type of a fiberglass pole. It has been a learning experience for me as I used the technique on various projects. Here's what I found. At first I used a rod that was made from a wire coat hanger.
It was cheap but, also had some disadvantages. You could bend it easily but, it would also stay bent and that was a problem when trying to "fish" it around sharp bends. It would sometimes get hung up. Another disadvantage was it was conductive. You run the risk of having it contact some terminal or breakthrough a wires insulating jacket causing a short circuit, fire or shock hazard. Not an ideal situation or the ideal tool to use.
I then went looking for a better solution and found it at my local Home Depot store. This was a Greenlee 540-12 Fish Stix kit.


Which consists of several 1/4" fiberglass poles that interlock and allow one to run or pull wires in tight spaces up to 12 feet. They cost about $35 bucks. It was better than poking behind bulkheads with a conductive piece of metal coat hanger wire but, still not perfect. They bent a little but, did not stay bent like the a coat hanger wire method. But, they were a little too stiff for some of bends I had to run wires through. I started thinking that I might be able to also use them for an idea I had for another project so they still might still be useful on board.
One day while looking through an online catalog. I came across the Cen-Tech wire running kit. Since they cost less then the Greenlee 540-12 Fish Stix. I bought two sets for this other project. When I got them I realized that they were the perfect tool for fishing wires on board my boat much better than using the Greenlee sticks. For one thing they were thinner than the Greenlee poles and much more flexible. As you can see in the photo below:

Another advantage of the Cen-Tech poles is they come with a flexible screw on tip.

This makes it even easier to snake the pole into tight bends and spaces. You can also get a flexible tip for the much stiffer Greenlee Fish Stix but, at extra cost. Below shows a photo of Cen-Tech pole making a tight bend behind a bulkhead before pulling a wire through.

If you've got some wires to run I recommend using something like the Cen-Tech product. They also have other uses on board. I've used them to knock out Barnacles that found their way into some of the through hulls. So if you need to do some "fishing" inside the boat this is the tool to use.

LIGHTHOUSE: Baron Bliss, Belize City

As a sailor I have an affinity for Lighthouses. They are structures whose comfort radiates outward to us sailors. So since I was staying at the Radisson Fort George Hotel in Belize City just a few minutes walk from Fort Point as the sailors call it. A visit to the Baron Bliss Lighthouse was in order.

The structure actually serves two purposes. It's a Lighthouse and a memorial to a fellow named Baron Henry Edward Ernest Victor Bliss. You can see his tomb at the base of the light off to the right in the photo below:

Bliss was an engineer by trade who made a fortune in oil futures. But, in a karmic twist of fate he became paralyzed at the age of 42. But, that did not stop Bliss from enjoying life. He moved aboard a yacht for the rest of his life and went fishing. After fishing his way through the Bahamas and Mexico. He and his yacht eventually ended up off the coast of Belize. Though he never set foot on the Belize mainland but, was still touched by the generosity of the Belize people.
When his health took a turn for the worse at age 57 he decided to donate a large part of his fortune to the people of Belize.

Bliss died soon after aboard his yacht, on March 9, 1926. The country erected this lighthouse/memorial to him and celebrate Baron Bliss Day every year in March.

WINTERLUDE 2010

Well winter is just a few weeks old but it feels like it's been around for a long time. Two feet of snow one week 8 inches the next. What's sailor to do? I don't know about you but, I'm heading south to Belize to get in some warm water sailing for the next ten days. I'll be back posting later in January.

INTERESTING PROPOSITIONS

One good thing about pulling the boat every year is that you get to inspect the hull without holding your breath or putting on Scuba gear. You can also look around the boat yard and see what other boat owners have for keels, props etc... Sometimes there are some mysteries as well. Such as what's the story behind this prop?


Did this boats owner never turn on his engine? Did he always sail off the mooring? Perhaps they never even got on the boat the whole season. Looks like they would have been in for a little surprise if they did need to use the motor considering the growth on the prop. Speaking of props I have a little mystery concerning BIANKA's prop. While polising it last spring I noticed some confusing markings on it.


From the numbers stamped on it I am assuming that it's a 16 inch diameter right handed prop. But, it appears that the original 14 inch pitch was restamped to 13 inch. Since I speced BIANKA with a 16 inch 14 inch pitch I will need to try and see how the 13 inch pitch would affect preformance under electric propulsion with the different pitch. Another reason why it's good to double check things on haulouts.

WHAT WORKS: SOLLIGHT LIGHTSHIP LED LIGHTS

Several years ago I bought two items called Lightships which are made by a company called Sollight. They have turned out to be one of the most reliable and trouble free items on board and just do what they are supposed to do. A sailor could not ask for more than that. They are small LED light fixtures that are solar charged. They look like miniature lunar lander or some high tech bug with their three legs and suction cups. The suction cups are there so you can mount them to a hatch like this:

Those suction cups are pretty tenacious too. The units stayed attached to the overhead hatches all season until I pulled them off to be used at home in the winter.

On the opposite side is a small solar panel that charges up the battery contained in the unit and a switch as shown here:

The three position switch allows the unit to switch on two white LEDS for general illumination or a red LED only so that night vision is not ruined while moving about the cabin. The third position is the off position and no light will come on at dusk. I purchased two units three years ago. I use one in the main cabin and the other in the head. I would not say that you'll be able to read by their light but, they will shed enough light so you won't be tripping over things in the middle of the night. The one I installed in the head is about as bright as a night light but, not so bright that it will jolt you awake like the other lights on board will do. Another good thing is you never have to worry about turning them off because they might drain the battery as they shut off at dawn and start charging with the first rays of dawn. They also make it look like someone in the cabin as they turn on at dusk even if you are ashore and therefore can act as a possible deterrent to a thief who does not like to take any chances. They get Capt. Mike's approval because they just plain work.
