How is the Encore Self Bailing?

One of the first questions a new Encore owner asks is “why is there water in the boat?”.  Reassuringly we say, it is supposed to be there!   Water comes through specifically designed holes in the bushing on the keels.  This allows water into the drive shaft channels at all times while the boat is in the water.   The level of water within the channels is dependent on weight within the boat.  Unmanned, the water will stay at its natural water line; if it rains you may see accumulation for a bit but once it stops it will drop to the natural waterline level within minutes.  The boat is self bailing in that sense and an advantage in areas that get rain more often.  As weight is added in the cockpit the boat will float a bit lower and the water in the channels will rise a bit.   If weight disbursement is uneven, you may notice a bit more water up and around the drive unit on the heavier side, this is completely normal and acceptable.  When the weight is taken out, the waterline will adjust to its natural state.  When the boat is taken out of the water, the channels will drain out the holes in the bushings.

The Polyethylene Advantage

All the boat hulls at Nauticraft are made using a polyethylene compound in a rotational molding process.  Positive attributes include natural buoyancy due to it’s specific gravity being lower than water…it floats! There are UV stabilizers added by the resin manufacturer to ensure long life even when sitting in the hot sun.  It is impact resistant in that it will withstand little bumps on the dock without cracking or crazing, and if it does get scratched the color is consistent throughout the wall thickness.  It has natural resistance to salt water environments. The walls of the hull are thick enough to allow structural integrity without adding weight, thus allowing a larger boat that weighs less than a typical counterpart.

Keep in mind that it is not indestructible!  We’ve heard of  scenarios of dragging the boats on rocky terrain and ramming them full speed into a rocky shore, and it didn’t bode well for the boat.  Using the guidelines listed, you can have years of enjoyment with your Nauticraft Pedal boat.

Pedal Drive Unit: Quadritwist Belt Drive

We are asked from time to time by prospective new customers just what our drive units are like and what is meant by the term “Quadritwist”.

As far as what our drive units are like, the first impression on seeing one in a Nauticraft boat is that it “belongs there”.  This visual impression comes from the drive unit housing being made from the same material as the boat – a white plastic with black specks (we had the black specks incorporated into the material a few years ago).

On our original drive unit (which we now also call our “inboard unit”) the driving belt twists four times going through its path, from the pedaling sprocket to the driven sprocket, over the idlers, and then back around to the start – hence the term “Quadritwist”.  We have a very positive regard for this system because it gives us the required directional change as well as the required speed increase (a 1:4 increase) with no energy robbing torsional or axial side effects; with this type of layout the twists of the belt are actually “natural” ones.

Looking further at the drive unit it is obvious that the pedal cranks come from the bicycle industry, and this is so, as we purchase these cranks as well as its axle assembly (known in the industry by the unlikely term “bottom bracket”) from a bicycle parts supply house.  The pedals also come from there and, because they are often used that way, are of the “barefoot” type (some sophisticated customers, familiar with upscale bicycling, sometimes change these pedals for their own particular choice).

An even closer inspection of the drive unit shows that the mechanical aspects (all of the moving parts) are located on the outside of the drive housing.  Our drive unit is designed this way because the mechanical parts (particularly the belt and sprockets – being of plastic materials) do not need oil or grease lubrication as do metal parts (the plastic materials also are not susceptible to water corrosion as are metals).  Also, because all mechanical assemblies need care and maintenance from time to time, it is far easier to service an assembly that is out in the open.  For instance, although it will serve for a long time, the drive belt can be changed for a new one without removing the drive unit from the boat – and without requiring any tools.

We designed this system ourselves (using the quadritwist philosophy originally proposed to us by Phil Thiel, a marine engineer from Seattle) and have been happily using it in our boats for over 15 years now, with only incidental changes.  We manufacture it right here in our own shop – from rotational molding the housing through all of the subsequent assembly steps.

Next time I’ll talk about the “swing down” drive unit used in our Sprite model – why it doesn’t use the quadritwist system, but how it is similar to it as well as how it is different.

Pedaling the Potomac

Escapade on the Potomac

I bought my Escapade in the spring of 2001 as a 50th birthday present to myself. I named my pedal boat RiverSong, and now—as my 12th boating season begins—I still love it as much as ever.

I lease a slip near the Pentagon from April through October and pedal the Potomac within view of the Washington Monument and Lincoln and Jefferson Memorials. I usually take my first ride of the year while the cherry trees are still in bloom and my last as flocks of geese are migrating south overhead. Sometimes I pedal past the Kennedy Center and ride as far as Georgetown.

Because I have a demanding job in DC, I don’t get out on the river every day, but I try to take at least one evening ride and one weekend ride each week. People are always commenting on my boat, and tourists ask where they can rent one.  The cleverest remark from a passerby was: “Oh, a two-stroke engine!”

Like most boaters, I appreciate the beauty of the water and sky at least as much as what’s on shore. The scenery is perpetually changing, as is the play of sunlight on water. Occasionally I have trailered my boat to state parks and enjoyed pedaling on gorgeous lakes. As my husband Don likes to say, “The purpose of a boat is to take all the water up there… and put it back there.”

Sometimes Don comes along for a ride, but usually our dog is my only passenger. Our cairn terrier Boscoe accompanied me to Michigan when I bought the boat to give it his “paw of approval.” Boscoe passed away six years ago, but our young dog Skruffy enjoys boating even more than Boscoe did. He thinks we own the Potomac.

Charging Battery after it has set all winter

Nauticraft recommends using an AGM sealed marine grade battery in the electric boat models.  The AGM has advantages over other types of batteries being it is more stable under charge than a Gel Cell, it is less likely to lose it’s charge when setting unused as a flooded wet cell does and it is maintenance free.  Even so, it is possible to have some charging difficulties with the AGM battery.  If your battery has been sitting for a few months or if it was depleted to less than 25% on the LED  Meter it may be helpful to put it on a trickle charger for 24 hours.  When you connect the higher amperage charger to a less than charged battery, the charger is unable to read any level at all coming from the battery, and it won’t process through the cycles.  If you’ve used a trickle charger and give it a good boost, the 6 amp charger will recognize there is a battery connected to it and do what it is designed to do!

Questions about Options

Nauticraft often gets asked about what is “needed” as far as options go, and we’ll be taking a look at those over the next few months.

Relating to the Christmas gifts which are being offered, customers ask if they need a Storage Cradle to store the boats on while out of the water.  The Storage Cradle was designed specifically for the Escapade pedal boat to accommodate the deep narrow keel of the boat.  The Escapade can’t sit on its keel as many flat bottom boats do, so when taken out of the water it lays on its side which may over time affect the shape of the hull.  The storage cradle is designed to fit the keel and also to hold the “belly” of the boat while keeping the boat upright.  It is also very useful during shipping, as supports are needed to keep the boat upright during the shipping process.  The Encore models do not need any sort of a storage cradle as it will set on the double keels and the bow of the boat without issues.

One thing about using a storage cradle is the challenge of getting the boat onto it.  The Escapade weights about 325 lbs, and is awkward to lift even with 4 people doing so.   Using a pulley system is a good bet when lifting the boat up onto the cradle.  For more specific instructions or for questions you may have contact Nauticraft directly at the factory.

Winterizing your Encore Pedal Boat

As Michiganders, we are used to cold and ice…brrrr…feeling it already!  The coldness won’t harm the hull, it’s made of durable polyethylene so it won’t become brittle like other materials exposed to the elements.  Even so, there are things to do to ensure your boat is protected.  The first thing is to take it out of the water if you know it will freeze.  There are all sorts of reasons to do this including damage ice can do the pedal drive system, protecting the seats and other manufactured parts from snow, ice, sleet, etc. and stopping the hull from becoming misshapen by moving ice flows.  These are also good reasons to keep it covered.  If you leave it outdoors, use a support to keep the cover well above the windshield to protect it from the weight of snow accumulation.

  • ENCORE
    • Raise the bow end of the boat; set it on a large block of Styrofoam (12″ x 12″ x 12″)which is placed somewhere between the bow and the front compartment.  This will allow water within the channels and the drive shafts to run out.
    •  Remove the drain plugs to allow any water which may have accumulated within the hull to drain out.  There shouldn’t be much, if any.  MAKE SURE TO REPLACE THE DRAIN PLUGS AFTER THIS PROCESS!
    • Remove the battery if it has one.  Store it in a garage or something like it, off of the concrete.  You can put it on a trickle charger periodically during the cold season to protect it from becoming too depleted.

    Contact Nauticraft by email or phone at (888) 709-7097 with any specific questions you may have concerning this subject.

Pure Michigan

With summer officially here, Nauticraft invites you to Michigan for a visit.  In looking at a US map you can’t miss it, it’s the state that looks like a mitten with all the water surrounding it.   There’s tons of stuff to do here, including fishing, boating, and watching the sunset over Lake Michigan.  There is golf courses that are nationally recognized, campgounds on the beach and fine dining.  Michigan hosts music festivals and county fairs, NASCAR  and Broadway shows.   We have our share of big cities and small towns, and some big cities with a small town feel. 

Go to Michigan.org to see all the great things going on in Michigan this summer!  And then take a look at Nauticraft Boats!

Health Benefits from Using Nauticraft Pedal Boats

This is a letter we received from one of our owners in Arkansas~

“My initial interest in Nauticraft was to be able to exercise my 300+ pound body as anything like walking or running was too hard on my knees. Then I found out a new and far more important reason to ‘Peddle Peddle Peddle’..Diabetes.

After the iinitialshock had passed the reality set in that my Doctor’s words ‘lose 75 pounds or give me your feet now’ was a real threat. The USS Diabetes DRV-1 had a new purpose and became the tool for beating diabetes.
My diabetic diet when combined with 1 hour a day in the boat proved within 6 months that I could beat this illness if I just kept at it. I lost 70 hard fought pounds and found an exercise that I couldn’t wait to do and now that the diabetes is in check I still peddle every morning for 1 hour and enjoying the outdoors and better health.

If you want to be outside and exercise on the water and work on your tan, get a boat from Nauticraft…sure it’s pricey, but so are Doctors and weight loss programs and DIABETES.”
