Hi George and All, In winds or getting
caught in a fast tide the boat could be out of control and you don't have
enough power to handle it. While it can move some in
good conditions, weather can go bad fast. What I said
still stands, ignore it if you want but my 45 yr boat design, building,
sailing, solar and powering experience says you need to be very careful and
have multiple large anchors.

Jerry,
Sorry for the long period for response. It was difficult for me to come to
fathom your reply, shown below this email.The MOG is a Totally Electric Powered
Solar boat. I have endeavored to respond to your quips and numbered them 1
through 8.
That is a lot of boat drag to either go fast or far.
1. The boat has logged at least 520 miles on one of its many travels. If you
read the MOG Log from our web site (originally cited) you would be better
informed.
Just not a great choice for solar power.
2. This MOG configuration has been hailed in myriad publications, by certified
naval architects, engineers and boat designers as one of the best applications
of solar power.
Next since it can only go max 5mph on E
3. Over a measured mile it has exceeded its maximum hull speed, 7 knots. The
hull design by Graham Byrnes, Naval Architect is very efficient.

Please notice the picture of the 22’ Cat Ketch he designed for racing (&
winning).
2 speeds would be fine.
4. Evidently you have been misinformed about boat handling of a 40 foot boat
negotiating in a marina fairway. 2 speeds is absurd.
Not likely to ever be more than a few mile range at low speed on electricity.
5. Think again please, there is no range limitation…. period. The boat has left
Oriental, NC and logged 40 miles on the Alligator (tidal) passage. It left at
100% and arrived at 94% charge (Sun).
only 1.5hp of solar now.
6. At 2,585 watts of just solar, the hp is 3.46, with no counting the added
storage from the 20 kW below deck. And that is only based on the present
prototype. 1.5 hp provides about 3 mph.
eCycle electric motors, super cap/battery amalgamations, advanced alkaline fuel
cells, thin/flexible PV modules' These are needlessly expensive or
just not viable at all.
7. “Primarily I asked for dialog”. How in heaven’s name do you twist that
request into my implementing any of the named items beyond the eCycle motor and
Navitas controller?Your conclusion that I want information on ‘buying’ eCycle
motors, cap/batteries amalgamations, advanced cells, flexible PVs is 100%
incorrect. I want to dialog with those people that have ‘used’ these items. You
have imposed your version of reality where it is totally inapplicable. Lastly
you tell me that these items are not viable for my application. You demonstrate
no experience in naval architecture, do not own a Navitas controller, have
never run an eCycle motor, do not possess a large array of flexible PV’s and I
challenge you to present an array of pictures and videos of a 40 foot boat you
have built, none the less designed.
Please stick to the author’s request and that was to dialog with those that
have such experience, rather than interjecting oneself into areas beyond actual
use.
A real canal/narrowboat would be great.
8. Some due diligence would suggest, that outside of a true narrow canal (no
waves, no flow and no tides), a flat bottom narrowboat is the worst of all
designs for intracoastal waters (our MOG’s stated area of navigation). Narrow
boats, a type of canal boat, are NOT to be used on large bodies of water and
tidal flows (fast water for a narrowboat is 2-3 mph). From a UK canal boat
site……
- Never go out in fast water. Locks on rivers have a guide showing the
height (and therefore speed) of the water, don't go out onto the river if the
guide is "in the red”.
A car (with which you have experience) may pull off the road, park and have
remedy to any common road situation unaffected by tide, wind, waves and sinking.
If you do not know something about the MOG Totally Electric Powered Solar boat,
kindly consult the sites I had provided, ask questions and I will reply nicely.

only go max 5mph on E and few miles depending on your battery pack hard to
justify it. And no need of expensive controllers, E cycle motors as 2 speeds
would be fine. No detail on the prop, which needs to be as large as
possible turning slow rpm for most eff. What kind of outboards,
inboards, KWHR and what it does now on them in speed, range. Not
likely to ever be more than a few mile range at low speed on electricity. But
driven slow like 4mph with more panels, only 1.5hp of solar now.
Answer these and we can go from there. Doing EV boats one needs to
start with a sailboat, mono, cat or tri hulls with much lower drag.

I have just joined and subscribe to EVDL with the idea that there are
likeminded folks interested in large EV boat design and building. The MOG is
not a commercial enterprise at this time but may be key to the creation of
such. Everything designed and implemented over the past 25 years is described
on the site given below and in the videos and blog that are also given below.
Primarily I ask for any dialog that would help in furthering the progress made
to date. In effect, those with knowledge of the Navitas NPS600 motor
controller, eCycle electric motors, super cap/battery amalgamations, advanced
alkaline fuel cells, thin/flexible PV modules, internal grid power distribution
DC networks and anything else that may be contemplated for such a craft is
welcome.
In its present form, the totally solar electric (drive and appliance) powered
boat is very functional. Considerations in decreasing onboard use of power as
well as better use of power now created and stored is paramount in continuing
further development.
To date, all of the boat design & build has been funded through my own personal
funds as a hobby. Below are the background data to which I referred.
Thank you in advance for your deliberation and comments. George
