A good size 27 is about right on a sail boat, with the next step up as two batteries of six volts each, one on each side.  Longer run time with twin 6 volts, for when the winds don't blow, or you want to motorsail back in.  The last lead acid batts. I got lately, have extra power, longer run time, at better cost to power, like 160 minutes at 25 amps - in 80 deg. temps.  They do that for $130.  My Minn Kotas use 15 amps each, smaller ones use less.  

Rough figures look to be about 100 amps before stop, so a lengthwise trip on Paulina lake with previous batteries.  Launched from the lodge, to camp, then back again to dock is about what I got on one trip with a lighter sail boat.  I would think most coot sail boats would be fine with that range.  Weather was calm on that trip, so evening winds mean you might need extra power to make it home, upwind still a problem.

I got stuck downwind on Dorena a few years back, had the Minn Kota at half throttle to help the sails get back to the dock.  Damn near didn't make that, keep power reserves for safety.  La Verne swamped the kayak and swam it back to shore, I could see her in the lake center, but no power to get out and back.  This at sundown !!  Enough to scare the poop out of us both !!

Later,  Cal

I just spoke with Sara (supper nice lady) there are slips available and yes they cost I believe 32.00 or something for the weekend and she says there are some available. Parking permits are 5.00 each day and with a slip you can access it with your boat. Seasonal passes are 40.00. Give her a call, she's very understanding.

Richardson and other reservations

Electri-Cal
 

Just tried to get this years prices on slips.  Apparently there are no slips available for the coots coming event, but I don't believe that.  I do believe the site is wrong, so Just have to show up and see what happens.  Still looking at that mast, and 2 sails from other projects, maybe yet this week I could figure a decent down wind rig just for the heck of it.  I was impressed with the kayak flying a round sail at Dexter a while ago, I ought to be able to come up with something.

I could try using that "slip on" sabot dinghy sail I have.  Fast is not important, just a battery saver, and seeing if my somewhat slow steering with Surprises normally fully submerged chine would work instead of a leaboard,  Maybe make an added shallow drop board to help turning speed, or slide it to balance the helm.   If it doesn't work easy, I'm still not out anything, just curious.

Re: Good Girl Gets a Motor (was: Correcting my EARLIER Instrument Notes on EV Power)

 

The CG reg only applies to permanent installations. You don't need to worry about that with a clamp-on trolling motor. The CG doesn't mess with little boats like ours for things like that anyway, and you'll never see them on Fern Ridge. <g> By "voltmeter" I meant a cheap Harbor Freight digital multimeter, like this one:

https://www.harborfreight.com/7-function-digital-multimeter-63759.html

That group 24 battery you got is about as small as I'd want to go. There may come a time when you have to motor quite a ways, especially if the wind dies and you have to get back to the ramp by sundown. <harrumph>

Be glad to let you take Good Girl out for trials on the power usage like you mentioned.

Re: Good Girl Gets a Motor (was: Correcting my EARLIER Instrument Notes on EV Power)

 

That's a good setup. You'd have to spend a lot more money to get a trolling motor with electronic speed control, and 30 lb. thrust should move Good Girl just fine. The runtime graphic is necessarily just a rough guide, but it does take into account Mr. Peukert. That motor should draw about 30 amps at full "throttle". It'd be nice to do some tests with an ammeter to see what it draws under typical conditions pushing Good Girl at the different speed settings. I did such a test with a 30 lb. Minn Kota on Pickle years ago but, alas, the results got lost in a computer upgrade since then. One of these days I'm gonna rig up a portable ammeter for doing trials like that, so maybe I can go out in Good Girl sometime for some test runs.

Get a digital voltmeter (cheap from harbor Freight will do) and keep an eye on the battery voltage now and then as you go along. I charged Tuffy's flooded cell batteries if they got down to 12 volts under light load -- my usual pace getting back to the dock after a sail -- which I figured was close enough to 50% discharge. The only really accurate way to to tell the state of charge by voltage is to let the battery rest for several hours before testing. Not very practical for us! <g> Here's some basic info about the Peukert effect and what I think is a practical voltage/state of charge chart, because it agrees with what I've been doing. <g>:

https://groups.io/g/oregoncoots/files/Motors/BatteryBasix.png

Don't sweat it if you have to go a little below 12 volts to get back to the dock, but recharge the battery right away, and promise to try to treat the battery better in the future. <g>

"Smart" battery chargers are getting cheaper and more common. I wouldn't be surprised to discover that they're the most common kind above the cheapest ones nowadays.

Re: Fern Ridge Water Level

 

Those of us who use Navionics can get an idea of how much smaller the usable lake is when the water is low. Go to the Menu, then Map Options, and adjust the water level to -5 ft. Today the level is actually about -4.5 ft. I've attached a couple of screenshots of the whole lake. I set the light blue shading at 6 ft. and the "shallow area" with the dots at 3 ft., which seems useful for our small boats. Be aware that the bathymetric data in Navionics is only an approximation.

I look forward to seeing you on the 15th or 16th, Dan! :o)

Just grabbing imaginary numbers out of the air... If the battery goes
down to 50% in an hour when you draw 20 amps from it, when you draw only
10 amps from it you don't double the time to get down to 50%, you
actually get _more than_ two hours run time. So it pays to go slower.
Even if you got the "best bang for the buck" cheap Minn Kota 30 lb. with
resistors to control the motor  speed (Ohm's law).

Get a good "smart charger" if you want to get the best life out of your
