ELECTRIC PROPULSION: SOME THOUGHTS ON ELECTRO-SAILING. PART ONE

I was awakened from my mid winter doldrums by an email from a fellow who had some questions about electro-sailing if he were to convert to electric propulsion:

"My wife and I are looking at converting our Vancouver 27 to electric. I think electric with approximately 200 amp hour 48v bank would meet all of our needs under normal conditions, but because there may be rare occasions

but because there may be rare occasions, like if we have to transit a canal the like Erie Canal, where we would need to motor for an extended period I am I am trying to determine if a small generator like the 2000i would be suitable to propel the boat at a slow speed for extended periods.

You stated that you could motor at about 3 knots with your 2000i generator. What charger do you use? Have you done this for several hours at a time? I am curious if you have experienced issues with heat build up, or other problems that might be an issue with extended use of the charger to power the electric engine."

These are great questions and ones I wondered about back in 2007 where I began to get serious about converting to electric propulsion. So I thought I'd make a blog post about my experience over the past nine seasons with electric propulsion and electro-sailing.

1) I am trying to determine if a small generator like the 2000i would be suitable to propel the boat at a slow speed for extended periods.

The answer is yes. I have found I don't really need to do it often but I have had to at times  motor up to 40 nautical miles just using a Honda 2000i generator and battery charger to move my 30 foot boat along. An example of such a day is shown in this video:

Again I have not had to do this often since at some point during most sailing days a breeze does kick up at some point. But, even if it does not I find electro-sailing with Electric Propulsion to be much quieter and much less vibration than when I had a diesel which makes for a much more pleasant day on the water.

I'll get into more specifics as to the components used on BIANKA for extended electro-sailing  and the things you need to know to make it possible in the next post.

MESSING ABOUT IN BOATS: Honda 2000i Oil Change Help

One of the maintenance rituals I do before launching is to change the oil in the Honda 2000 EU generator. I've been able to significantly reduce the the mess of this procedure by using a Hopkins Measure Funnel:

While this eliminates a lot of the mess of the oil changing procedure I still...

WINTER HEAT

 It's looking like another cold cold winter here at Rancho de Captain Mike. I write this staring at slushy cold winter landscape in the middle of a winter storm watch. Earlier this week a Blizzard hit the area dropping about two feet of snow. I had spent most of January in the Caribbean hoping to miss the worst of the winter. Looks like I was a few weeks too short. After digging out from the blizzard I still had icy patches on the walks. Then I remembered I still had some items on the winterizing check list from the boat. As usual I had taken the Honda 2000 generator off the boat for the winter. One of the nice things about being able to use the Honda 2000 for my on board electric propulsion system is it's portability. I take it home just in case I may need it if the power goes out over the winter. I also get it ready for the next boating season. I had not yet drained the gas entirely from it's gas tank when the blizzard hit. So in order to kill two birds with one stone I fired up the generator and used it to help melt the icy part of the walkway with it's downward facing heat exhaust:

As you can see it does a good job melting the ice. I just move it along the path ever few minutes until it had used up all the fuel that was left in the fuel tank.  As an added bonus I also hooked a radiant Dish Heater in the garage and used it to help warm me up during breaks  as I continued to dig out from the storm. After seven years the Honda 2000 generator continues to be a useful and  versatile workhorse both on and off the boat.

HURRICANE SANDY: AFTERMATH DAY FOUR and FIVE

I am noticing a difference at night while living on board BIANKA. The harbor the first night on Tuesday had a different feel to it. Mostly because the lights of the beach parking lot and those houses in the surrounding hills were dark due to the power outages. The nearly full moon rose and played peak a boo in the swirling clouds that were the remnants of Sandy.  It was very calm and somewhat warm enough that I was able to have dinner in the cockpit and enjoy the scene.

On Thursday I drove home to check on the house which was still without power  and did some yard cleanup before returning to BIANKA for the night. It was comforting to return to BIANKA where I had power and food available thanks to solar and wind power which were doing a nice job keeping things topped up. But, I did fire up the generator as the cloud cover during the day did keep the 12 volt house bank a little under charged.  It did not take long to fully charge it and I used the waste heat from the Honda generator to totally dry the portion of the quit on my bunk that got wet from the open over head hatch. I enjoyed the nights dinner which was Pasta with Captain Mike's homemade Bolognese sauce. It was a colder night than the previous ones but, under the down quilt in BIANKA's cabin I did not notice it.

On Friday I bought the boat to the dock as the boatyard boss was getting antsy to pull her and put BIANKA in the special corner where I get a very nice harbor view over the winter as I work on projects. He wants to do this soon so that he can also put in other boats in front of her and fill up the yard. I've finished the water from the 50 gallon tank on board and switched over to the 30 gallon tank so I guess it's time to think about ending the season anyway. I tried grappling for the lost Honda BP-2 outboard but, I was not able to find it. I may try again over the weekend. A gusty wind kept the Marine Air-X wind turbine spinning all day  nicely adding some  amps into the battery bank and we had enough sun that I did not need to use the Honda 2000 generator to top things up. Driving home to check on the house I notice that gas has become an issue with many gas stations closed because of no supply and those that were open had long lines and Police directing traffic. This is not a crucial issue on an electric boat like BIANKA  the solar and wind generation are able to keep up with my demands while I live on board most days. I heard some scuttlebutt in the boatyard about hiring private security to keep an eye on things. As contractors in the area were finding it hard to find fuel for their trucks and a boatyard full of diesel fueled boats was a tempting target. As for me I will be hiding the half gallon of gas I have on board for the Honda generator and sleeping with one eye open.

HONDA 2000i GENERATOR REPAIR: Pull Cord Replacement

Tweet
I've mention that my Honda 2000i generator has been very reliable for the past five years. So reliable that when it came time to repair it there was a lot of aggravation involved. The original problem was an expected one. The pull cord that allows one to start the engine broke. A simple problem that will probably befall all generators at some point if they are used often enough. What I did not expect was how seized up the outside screws that hold the 2000i covers on would be.

 The aggravation was in how long it would take to remove them. In addition some of the screws were ...
