A few weeks ago I did another of the annual harbor tests I have been doing on BIANKA's electric propulsion system. Here is a graph of the results:

Results are similar to least years tests with no real significant differences. Here is a graph of this years data compared with the 2014 test:

Some of the other data comparisons of the tests:

 The % battery at the end of the test was 89.7% compared to 90.6% last year.

The Amp Hours used for the test was 16.5 compared to 15.2 for the 2014 test.

NOTE: Some of the increase may be due to the distance traveled for the the test. This year the distance traveled for the test was 2.2 nm while in 2014 it was 1.8 nm. The difference might be explained by the location of the buoys which are removed and replaced each year in the harbor.

The tests show that the Thoosa electric propulsion system is still preforming well. It has been eight years after I installed it.  Along with  the reduction in maintenance and cost savings it continues to reinforce the notion  that it was a good decision to convert to electric propulsion back in 2007.

Winds and WIFI

I have not been posting too much on this Blog lately. Not because there is nothing to write about but, because the cellular/internet connection is so bad in BIANKA's home port. It makes posting frustrating and tedious. Much like the winds yesterday as I started a cruise to New York which were light and from the wrong direction. So I decided to change my plans and ducked into a harbor only three miles from the homeport where the cell signals are better. I'll hang out here for a few days enjoying the better communications and sunsets. Cruising is sometimes about just finding a better place. Even if it is only a few miles down the coast.

I've been wearing an inflatable Life Jacket on board BIANKA for decades. Happily, I've never had to use it.  Since it has automatic inflation I've always thought it would save me if I ever went into the water in an unconscious state. I thought it was the best lifesaving device I could wear until I saw...

It's nice when a project lends it's self to another project benefit. Such was the case with the cabin wood molding project I completed to cover up the handrail access openings. I thought that I might mount a fan to the molding at some point. But, then I thought that  the wood molding strip would also provide an excellent mounting place for ...

Looking through my emergency signalling canister this spring I found four handheld Handheld Signal Flares. Since it was the Fourth of July I thought it might be a good time to dispose of them by lighting them off on the shore. Seems to me learning and lighting about emergency signal flares is best tried with out being under an emergency situation. So soon after sunset I took the dingy to shore along with a large metal can that I would use to hold the flares after I set them off. It was an eye opening experience. While these flares are meant to be handheld the flame is extremely hot. They can also sputter dropping hot flaming particles about. How hot are these flares? Hot enough to melt through the metal can that I put them in:

That's pretty hot! If a handheld emergency flare can melt the metal can. Imagine what it will do to a fiberglass deck or the pontoon of an inflatable!
LESSON LEARNED: If you need to light an emergency handheld flare make sure you hold it far enough over the side so that it won't cause a fire on deck or damage your life raft.

Showing the flag on the Fourth of July is always seems a little more special somehow.
