THE ELECTRIC PADDLE: Part Two: Capt. Mike's Review

When it looked like the costs of trying to resuscitate the Honda 2HP outboard drowned by superstorm Sandy were going to head upward by several hundred dollars. I decided it was time to move on. Since I had already converted BIANKA to electric propulsion getting an electric outboard seemed like the logical choice. As I explained in the previous post I did not use the gas powered Honda too often. Using it mostly when the winds would make rowing the dingy tough if not impossible and some occasional gunkholing. Though it was under thirty pounds moving it on board and installing it in the dingy was sometimes dicey. So when looking at the alternatives I had several choices for an Electric outboard. There were trolling motors. Though they required that I carry a hefty battery on board to use it. A Torqueedo outboard which are nice though a little pricy for my needs. Finally,  there was the Electric Paddle made by PropEle Electric Boat Motors. It was an electric outboard I was intrigued with it since I first blogged about it several years ago. It seemed to be the right fit for my needs so I bought one:

As you can see it is small enough to fit on the cabin table along with the battery pack, charger and the spares that come with it. It is very light and compact and is much easier to stow under the cockpit without the worry of leaking oil and other fluids. It was about two hundred dollars more than a new Honda BF2 outboard would be. But, there are no oil changes, zincs, lower lube or winterization costs like with the gas powered Honda. It also means I need to carry less gasoline on board. Indeed maintenance seems to only involve dipping the lower unit into a bucket of fresh water and letting it drain.

It's designed for propelling small yacht tenders, rowboats, canoes, kayaks and sailing dinghies less than 9 feet long and under 800 pounds when loaded. So it looked like it would work well with my 8 foot Porta Boat and it does.

Both the Electric Paddle and it's 24 volt battery pack  fit very nice and compact on the transom. The battery pack hangs suspended on the locking handle out of the way and off the bottom of the dingy. There is no concern it will be sliding around if the boat gets hit by a wake. The motor and battery pack each weigh only eight pounds and are much easier to install on the dingy than the 28 pound Honda gas outboard. I am able to hold it in one hand and still have one hand for the boat. I never felt it or me had the possibility of going overboard while trying to attach it to the transom in rough conditions. PropEle also make a 12 volt Electric Paddle without battery or charger too.

It has a magnetic key attached to a lanyard that inserts into the steering handle and stops if it is pulled out. It also has a safety start feature in that the motor will not start unless the throttle is first turn to the off position. So that there is no sudden unplanned forward movement when inserting the key. Another nice thing about electric outboards is unlike small gas outboards you won't knock out your passengers or spouses teeth when pulling the starter cord because there is none. A turn of the throttle and you are moving. Connection between the motor and the battery pack is with a secure waterproof connector:

 I've left the Electric Paddle hooked in the dingy during several rainstorms with no ill effects. I've also inadvertently left the throttle control laying in water in the bottom of the dingy when I tilted the unit up and it has not caused any problem. That's because the design uses waterproof magnetic hall effect sensors for the control.  Adjusting the tilt of the Electric Paddle is very easy as shown in this video:



Note: You don't have to be in the water to make the adjustment. It was just easier to get a good camera angle for the video.

Another nice feature is the ability to slide the shaft and prop up in the bracket when tilting the motor up:

This makes it easier to reach the prop to clear it of weeds. Though the Joe Grez the Industrial Product Designer who designed the Electric Paddle said usually all one has to do it power the prop a second or two once it is out of the water and any debris goes spinning off easily. Speaking of props the Electric Paddle uses a large diameter, high pitch, high aspect prop like those used on propeller airplanes. But, Electric Paddle uses one that is specifically designed to be efficient at lower RPM's needed for pushing a boat through the water.

When using the Electric Paddle I have recorded speed tests of 2.2 miles per hour using the GPS app on my cell phone:

Which is just .1 MPH below the minimum specs the manual says I should be getting. Though playing around with the tilt angle may improve that. I'm still very happy with it's performance.

The Electric Paddle comes with an extra magnetic key, key for the motor lock, spare cotter pin and prop.

Having used the Electric Paddle during this past season I have to admit I'm getting a little spoiled. I've been using it more and rowing less. In part because it is so much easier to carry and install than the old gas outboard. I've used the Electric Paddle outboard more in just this past season than I have the old gas outboard in the past five years. I'm sure I'll be using it more in the future. I don't miss the old outboard at all. It was a gas guzzler and very noisy. The Electric Paddle is quiet enough to be able to have a quick conversation while passing other moored boats without slowing down. Because it is so quiet it makes great for gunkholing and bird watching.  To charge the battery pack requires 120 volts but, it can be charged with an on board inverter that is only 200 watts or larger.

In short if you are use to speeding across the harbor with a 15 HP outboard doing 15 knots in a 12 foot inflatable sitting over the gas tank with a cigarette dangling from your mouth. Then the Electric Paddle is not for you. But, if you need a quiet,reliable, low maintenance,  easy to store and carry electric propulsion system for the dingy to get back and forth to the dock at speeds that won't get you in trouble with the Harbor Police then it might be just the thing. You can also use it on your  Kayak or Canoe too so it's more versatile than the gas outboard too . For my needs the Electric Paddle gets the Capt. Mike thumbs up. It's a welcome addition on board BIANKA. One that I'll be using more than the old gas outboard.

THE ELECTRIC PADDLE: Part One: What's in the box.

When I bought BIANKA in 1995 she had on board a Honda BF 20SA outboard a 2 HP four stroke outboard for use with the dingy.

 I did not use it a lot and most of the time it stayed down below in the cockpit locker. It weighed only 35 pounds and was small enough to fit there though one it was a little awkward to lift out sometimes. The outboards metal fins or handle would sometimes catch on stored lines and other items stored next to it. Since I did not use it all that often it was not a big issue. I mostly rowed the dingy. On occasions when I actually used it I found it noisy (especially after having converting the mother ship to electric propulsion) and a real gas guzzler when compared to the on board Honda 2000 generator I used for charging the electric propulsion system. Still it was nice to have on board and be able to use it when the need arose. Like other Honda products it was pretty reliable so it stayed on board.

At the end of October 2012 I was preparing BIANKA for what would become super storm SANDY. The winds the day before while I was on board preparing for the storm were blowing 20 to 25 knots from the northeast and the dock I needed to bring the dingy back to was located northwest. I was not sure I would be able to row the dingy in the docks direction without first being blown across the harbor. So I decided it would be prudent to bring out the Honda outboard and have it available on the Porta Boat dingy in case the winds prevented me from rowing to my destination.  It turns out I was able to row to the docks crabbing the dingy with just the oars and never needed to fire up the outboard. When I got inside the marina I tied the dingy to one of the docks protected by high bulkhead. I left the motor on the dingy just in case I would need to use  it once the worst of the storm had past to get back to the boat. I thought the dingy would be protected from the worst of the storm but, I was wrong. The dock it was tied to broke apart:

When it broke apart it flipped the dingy and sent the Honda BF 20 outboard to the bottom. I spent a few days with a grapple until I finally snagged it and brought to the surface. A few crabs and small fish had already tried to make a home inside the cover:

I quickly rinsed the outboard in fresh water and sprayed it liberally with WD-40. I spent a number of days over the winter trying to remove one or two screws that had over the years became severely corroded even before Sandy. It took several attempts using  PB Blaster . to remove them. By then the carburetor had signs of severe corrosion. Still I continued on the taking it apart:

 In the spring I started to look at the economics of trying to resurrect the thirteen plus year drowned outboard and decide it might not be worth it on such an old engine. So I started to look for a replacement.

I had done a post about a small electric outboard called The Electric Paddle back in 2011. I was intrigued with it's concept and it seemed like it was really what I needed for my dingy use. But, since I'm a "if it ain't broke don't fix it sailor" and the Honda BF20 was still working for me it did not pass the "want vs need" test. The drowning of the Honda outboard during Sandy changed all that. So earlier this season I decided to buy the Electric Paddle. It did cost more that replacing the Honda outboard but, my experience with converting to electric propulsion on BIANKA and it's low maintenance and high reliability tipped the equation toward buying it. It was also cheaper than other electric outboards like the Torqueedo's. It arrived just a few days after ordering it. It's made in the U.S.A built in the Pacific Northwest by a family run business. When it arrived I took the box on board here's what I found when I opened it up:



In the next post I'll share my experience with using the Electric Paddle.

WINTER COMES TO THE HARBOR

Tweet

Well winter has finally arrived and the docks that were filled with power boats are now empty and so is much of the harbor that was filled with hundreds of boats.

Even the moorings are gone. Leaving no trace that sailboats like BIANKA where ever in the harbor. But, not all the boats have gone into hibernation mode. They boatyard was still pulling the boats of the commercial fisherman:

 Cleaning the bottoms, replacing props, engines and whatever else has to be done. One would think winter time would be a time of scarce resources for much of the wildlife of the harbor. But, different species of ducks from the north have replaced others that have moved south. Sightings of Arctic Snowy Owls have been reported. Meanwhile, the local Seagulls have been enjoying a seasonal treat in the town marina parking lot. Where the marinas floating docks have been hauled out to ride out the winter on the pavement.

The sides and flotation packs are coated with plump mussels and barnacles and the seagulls have all winter to gorge themselves on the easy pickings:

So though the activity has changed there are still things going on in and around the harbor and why I still enjoy coming down and being on the boat no matter what the season.

THE SHIPPING FORECAST

We here in the states are stuck with the semi droning artificial voices for the NOAA VHF radio marine forecasts. Over in England humans still read the weather forecasts for shipping interests and boaters around the island nation. It also attracts it share of landlubbers also. Books have been written about The Shipping Forecast like Attention All Shipping: A Journey Round the Shipping Forecast (Radio 4 Book of the Week) or And Now the Shipping Forecast: A Tide of History Around Our Shores. Another is a book of paintings of locations and areas mentioned in The Shipping Forecast called Rain Later, Good: Painting the Shipping Forecast
  National Public Radio had an interesting report about the allure of the Shipping Forecast that can be found here.  It is interesting to hear how all of the English waters are covered in one broadcast while here in the states forecasts are more localized.

SOMETHING NEW IN NEW YORK HARBOR: CHART 12334

Tweet
NOAA has just announced that a new edition of Nautical Chart 12334 which covers New York Harbor. This latest edition includes new depth measurements and shoreline depictions.  Since it covers changes that occurred since super storm Sandy devastated the area it's probably a good idea to update as soon as possible.  I had cruised through the area just a few days before that storm hit and have not been back since. So I will definitely be updating my chart before heading there again.  It's always important to try and keep charts up to date. Here's an example. This is look at the special anchorage 20A around Ellis Island in New York Harbor from the chart 12334 edition 37:

Here is the same anchorage area from the new updated 12334 72nd edition chart:

There are changes in depth and more obstructions charted in the post Sandy chart. Also good to know is how the anchorage has changed over the years. Including the addition of a security zone around Ellis and Liberty Island which has been in effect since after 9/11 terrorist attack. Not being aware of it is sure to invite a visit from the Coast Guard, National Park Service or New York Marine Police. So you definitely want to avoid entering or anchoring inside that area. You can download a  free PDF file of the chart here  and also as free raster navigational chart here. Print on demand charts are available at your local chart supplier.

THE HEAT IS ON

It was 25 degrees fahrenheit outside this morning.  Even though technically it is still fall here in the northeast it sure feels like winter already and I'm reminded that I  really need to go check on the boat despite the cold temperatures. When I bought BIANKA it came with a Espar diesel heater installed. Which came in handy during early April and late fall sails to and from New York where I lived aboard the boat. Since I no longer carry diesel on board after converting to electric propulsion the diesel heater has not been used in years. But, in the off season while working on the boat I do have supplemental heat in the form of an Holmes  Compact Ceramic Heater .
I also used it on board when the boat was at the dock in New York. It provides nice heat in a small package. It can even fit under the steps blowing heat along the cabin floor or on a counter blowing a dry heat toward the bunk keeping one nice and toasty. It has a thermostat but, I never keep it on unless I am on the boat. The boatyard also has a policy of not allowing any electrical power to be connected unless you are on the boat. Which is a good idea since fires can start if heaters are left unattended. But, when working on the boat on a cold day it helps make things nice and toasty in the cabin as one waits for the warm  Summer Wind to once again arrive.

NOTES OF AN ELECTRIC SAILOR: Harbor Test 2013 Part One

Tweet
Back in early June I had just splashed BIANKA but, had to wait for the boatyard to step the mast. Since I had nothing else pressing on board I thought I would take the opportunity to do some testing of the electric propulsion system both without and with the mast installed. So that's what I did. I made several runs between two buoys in the harbor that were 450 yards apart. I did a similar test back in the fall of 2011. Though I conducted these tests with a cleaner bottom since the boat had recently been splashed.

The mast on my 30 foot Nonsuch weighs about 300 lbs which is pretty heavy compared to a lot of other boats the same size. So I was curious to see what effect the mast weight might have on the boats performance. Like the test I did in 2011 I made two passes between the buoys. One going east and then turning around and making another pass going west. They were made at various current draws from the 48 volt battery bank of 10, 20, 30, 40 and 50 amps. The two passes were averaged to take into account any tidal current pluses and minus to the speed.
Here is the graph comparing the speed both with and without the mast on board:

As you can see there is a slight difference at the low end and upper end of the speed data. But, only about a  quarter of a knot or so. The sweet spot seems to be right around 3 to 4 knot range where both graphs are pretty close. Out of curosity I took the data from the Harbor Test of fall 2011 and added it to the above graph's data:

What's interesting to note is that the 2011 test data was taken at the end of the season just before I pulled the boat for the winter. The hull and prop had not been cleaned for probably a month or more:

So that growth seemed to have had some effect on that test data.
