I agree 100%. Just like EV's a solar boat is not for -everything-, it is for going slowly where the trip is tha value, not getting anywhere in particular. My solar boat only goes 3 MPH, yet when we take people out for a cruise, its like sailing (but don't need wind). You just enjoy everyone's company, the wine and cheze and the boat just goes where we tell it. Oh, and it has shade for 10 people...
No, never plan on taking it out of the creek, nor in any but the best weather. but as a party boat, it is perfect! http://aprs.org/alternative-energy.html <== about 40% down the page. See the existing solar boat and the planned "solar deck" to be built this summer. (to provide 3 kW of grid tie, the 99% it is not in use)... Cant wait to eventually program it with a waypoint tracker and just let the party barge take us on the several pre-ordained cruises. Select from the 1,2,3,4,5, or 6 hour trip menu and sit back and enjoy the trip and the company.

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. http://towndock.net/news/boat-designer-and-teacher-graham-byrnes-honored?p g=1 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.

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.
