Holding Pattern

Priced now at $650k

The continuing saga of remaining in the slip

This was to be the summer of making short to medium trips around North Carolina while adding miles to the Great Loop. The one hangup left has nothing to do with the boat, instead it is with the land base known as our condo on the Wilmington, NC waterfront. It is still for sale and we intend to sit tight here in Wilmington during the sales process.

Eight story 7 mile water view

Built to be incomparable, it has remained true to the word. There will be no actual comps (comparable condos) for another nearly two years. Next door to our condo are the diggings for River Place condos that should be finished in 2020. They had a number of fits and starts but are now sinking support piles deep into the ground.

The main difference is that our two bedroom, two bath 1,200 SF condo has both river and city views making it more expensive than the condos that are on their way. With no comps it is more difficult to sell but the reward for the buyer is again, incomparable.

Down sizing for the two years+ of the Great Loop experience is now almost completed, no small task. Neither the wife or I want to be miles away only to get a phone call that some item at the Water Street Center (our condo building) needs attention and personal involvement. Water, sunshine, swimming and food are all I want on my mind, not houses, farms and condos, all except one that are now off our sell list.

In the meanwhile

Half a dozen well vetted potential buyers have come through the unique condo. Not a one has been anything but impressed and generally using the words jaw dropping. The problem is that they too are downsizing. The condo is the right size, two car free parking, in the middle of the city life, etcetera but people have to make decisions to discard stuff, stuff that kids, relatives and friends do not want.
However, people are grinding through for their Great Loop experience or a final 'just the right size' retirement place.

Our listing info

Thirty feet of waterfront, eighth floor, 7 mile view balcony with a 180 degree view of the Cape Fear River.
The entrance balcony on the City side of the condo is just as sweeping.

Other mentions

We have entered the Create the Future Contest using a different point of view. At the insistence of a few boat and land folks, we placed the Totally Electric Powered Solar (TEPStm) boat in the competition classification as Sustainable Technologies. Our take is that it is a superb Bug-Out destination, which happens to be a boat.

During the winter, the January-February months at about 34 degrees latitude, provide a low sun for the solar modules atop the boat. Even on a very clear sunny day at this latitude in Wilmington, NC, the electrical capture rate is low. In the summer the sun light is more directly over head, yielding a much better rate of electrical collection.

The winter sun test was to help us understand how to find and use the balance point between incoming sun energy to simultaneously replenish the drive motor(s) usage under water travel conditions.  Except for the three motors being used for exit and entry to the slip, just one motor was used, with the other two dragging in the water. Later, the two draggers will get lifted, just not this time out.

It is quite ordinary to use math to indicate usage in watt hours but those numbers do not give the captain a realistic feel of how tide, wind, clouds, humidity and seasonal sky position directly effect boat control. Just as with a wind sail boat, a solar sail boat takes practice getting use to the interplay of the many facets of power usage.

On the road (um) on the river again to probe a bit deeper into how the boat handles and refuels with a winter sky.


Our battery bank system is comprised of standard flooded lead acid batteries of deep cycle design, similar to a car battery but having the ability to provide a longer duration of power than a car battery's brief high load for engine starts. We have finally gotten a good sunny winter day with low wind with reduced tidal flow in order to set a base line of drive power needed to make the boat move with control and maneuvering capability.

Once out of the slip/fairway and into the river, there are no protections from wind and the mix of river & tide flow. Eddy currents near and around the marina and especially at the center of confined bridge water flow tend to shove boats around, requiring the capain to increase the drive power to offset swirling water conditions.

We found that a speeds of 3 to 5 miles per hour were needed to keep the boat on desired headings in average river & tide conditions, require 300 to 500 watts of continuos power.
In order to keep the batteries from being depleted, the solar modules atop the roof had to replace such an amount. That amount was provided, allowing operation that although comparetively slow for other boats, was suitable for rudimentary navigation.

Around the bridge, very squirrely currents require a bit of steering. Awaiting the closure and reopening is rewarded with an addition of energy to the batteries. We were definitely not rocketing along at 3 to 5 mph but there is no range limitation. If you are retired, as we are, time is more than money, it is fuel.

Taking a close view of the underside of the Cape Fear Hilton railroad bridge on the return leg of our brief sojourn.

Awaiting the bridge opening, having a snack, reading, taking pictures or conversing makes use of the  sun. Quite amazing that a few minutes with a large enough solar array, will top off the battery banks. After a quarter century of collecting the sun's energy this way, the fact that we are actually doing such is still impressive to me.

The bridge and the batteries are up, continuing the equilibrium of power in, power out.

There will be only a few more nice days such as Tuesday February 6, 2018. These videos will serve to remind us of how we got out and back, at what level of energy, distance, time and ease of control.

Heading back to the slip with grins and more knowledge about solar sailing.

Once back in the slip we just became another 40 foot boat. However, until you have piloted such a boat, just using the sun, no fuels, no wind, no sails, no noise and no smells, you will have missed the power of nothing.

More to come.

MOG is Uplifting

Making light work lighter   

Although the Torqeedo Cuise 2.0 is very light weight at only 36 pounds, we have attached it to a motor mount jack plate of nearly 20 additional pounds. The plate easily slides into and out of the jack plate receiver bolted to the transom, making it possible to remove the motors when leaving the boat for a long period or to change a propeller while in deep water. 

A small permanent strap will be added instead of a lasso around the motor's top.
The lift strap must be made in such a way as not to cover the GPS antenna
 inside the the black plastic motor head cover

The idea of performing the task (with or without the heavy jack plate) can easily become precarious if the wind and water gets rough. I have placed and removed the motor with and without the jack plate, alone, with just my bare hands. It is easy enough but should there be a departure from calm conditions, I want a much more controllable rig. 

A single sheave pulley is used for the lift or a double sheave pulley can be used.

With some 2 by 2" wood, cardboard and tape, a prototype was cobbled together to fit onto the existing jack plate assemblies (typically used for 300 hp outboards of about 600 pounds). With some diligent effort, the design emerged into 2 by 2" square aluminum tubing, pulley set, attach/detach plate all to be TIG welded together. 

Torqeedo was very smart in providing the outboard with a reinforced rubber skeg.
The skeg allows one to rest the motor on the transom before lowering it to the cockpit floor.

The result is a lightweight, storable, easily deployed, simply used and quick operating lift for electric outboards of about 100 pounds. The current Torqeedo motors are about 36 pounds and with the jack plate attached, is about 56 pounds. The new lift is a most desirable addition to the onboard tackle and can serve a few other services to boot.

At this point the lift line would be unsnapped from the lift motor lift strap, to
stow the outboard inside the cabin.

Lift removed from center mount and attached to the port motor jack plate receiver.

Then the lift is removed again, simply snapping onto the starboard jack plate receiver.
