[Electric Boats] Prop Wash [1 Attachment]

 
[Attachment(s) from albert682@yahoo.com [electricboats] included below]

Launched last week.  http://www.marinetraffic.com/en/ais/home/shipid:3824576/zoom:10

Sea Trials and fine tuning of systems continues until the sonar is installed properly, the autopilot is working and there is less sawing at the helm.

We have twin Ray Electric Outboards and tried them offset one foot from the hulls on the first day from the travel lift and much sawing to get to the slip.  A few days latter we constructed a different mount and placed the outboards behind each hull slightly off center towards the center of the boat.  Then we motored the track given above.

Looking for a solution to implement counter rotating props for a Ray Electric Outboard.  I haven't been able to find any actual prop data other than it is a 12 1/2" x 10" weedless propeller.  If I could find a prop of the same type but opposite rotation I could invert a controller and run the motor in reverse and everything would be good.

Otherwise we are going to try placing the motors very close together at center of the boat next to see if that reduces the sawing at the helm.

The boat ended up weighing 5400 lbs so it actually weighed less than the last survey in 2011 and we made not many efforts to reduce weight on the boat aside from emptying the water tanks.

[Electric Boats] Elecric Propulsion at Strictly Sail Pacific April 7 through April 10

 


I hope some of you may join us at Strictly Sail Pacific for the largest display of electric propulsion systems in North America.  Strictly Sail Pacific is the largest and oldest in-water sailboat show on the West Coast and hosts the very latest in the world of sailing.  The new location is much larger and has plenty of parking.  There is a very large indoor show room and a marina full of new sailboats. 

 

There will be a number of quality marine eletric propulsion vendors including:  Electric Yacht, Thoosa, ePropmarine, and Torqeedo.  Additionally there will be wind, solar, and hydro generation systems.  There will finally be a number of presentations for both the sailor and electric propulsion supporter.

Re: [Electric Boats] Re: EV Boats, Reducing personal builds

 

I guess that was another inquiry.  What sort of boat are you looking for??  I haven't set up for any one to go immediately, unless the new owner is interested in a bit of trim repaint at this point.  it is too wet yet to do anything that way so far this year. 

Of course the inflatable is ok to go, but that is a dinghy, not a trailer boat.  The folding dink would be one that needs to go, but that also has to have a sand and repaint.   I figure it could be June before it gets warm enough outside to paint anything, the new one included.

Thanks for asking, how can I help ??  -----   Cal

Re: [Electric Boats] EV Boats, Reducing personal builds --- Oregon located

 

Almost forgot, those interested might need to know I am in Oregon, close to Eugene.  One inquiry was from Maine, that's a pretty good trip from the east coast.
 
Thanks,   Cal

Over this spring I plan on reducing my "fleet".  One is a 12 ft. sail boat, centerboard & beaching rudder.  Two 27 Deep Cycles control a Minn kota 40 .  The motor is in front of the rudder, so it can be steered remotely from a center seat.  All steering, all sail handling, rowing, electric switching, is done from one place, no jumping around.  It is very stable, beaches on a flat bottom, and trailers easy.

 
Later I will have a 17 ft. garvey design to part with. Very comfy, sleeps two in the cabin, and space for lots of storage.  Side console with swivel bucket seats.  The whole cabin is removable, or just the center skylight, which allows for exiting over the bow even with the cabin in place.  Power is a golden motor 5kv unit, newest controller, complete dash instruments, foot throttle, water cooled, installed on a Evinrude 48 commercial lower unit, freshly gone through by a pro shop.  Swings a 12.5 by 12 pitch prop, brand new.  Before I got that big prop and Skeggard for better control, It made noise.  No more, new prop stopped that so well we can hear the wake bubbling, and talk in normal tones.  Batteries are 4 Interstate 27s, deep cycle marine.
 
Oh, yeah, if somebody wants a 12 ft. folding ply boat made for electric I have one that fits inside a Toyota bed and locks down.  Small motor hidden under seat, steers with the double paddle, battery under the seat.  Shallow "V" hull and will carry my 235 lbs plus more.  Goes together in 10 min, made it to keep up with kayaks when the wind picks up.  great little exploration boat, but needs repaint from leaving in the barn .
 
I'm working on another EV now, 18 ft. but need more room.  Decided to start selling off completed projects.  If anybody wants details I can be reached at  calboats@gmail.com .    I plan on taking some time to find a good home for these, just as long as the new one gets done before the others are gone.  There is also a mostly done and fast kayak, and I have an inflatable 9 ft. with light inflatable floor, beach wheels, and a motor mount that raises to fit -- spaced about a foot behind the solid transom.  That gives close to a foot more room inside.  The great idea for a dink, been inside the barn, so it doesn't get used, just dusty.
 
I can do some pix, if any folks are interested, haven't set prices yet either, as I need to do touch up and add a bit for whatever is needed.
 
Time to make room, eh --- Cal
