Yes John, and other Coots who have missed some posts. 

The converters wired up just fine from what  it looks like on the bench.  I'd ike to know the amps rating on that pack is too, but capacity!!  that never seems to be an exact science once the actual motor, water condition, and relevant wid is altering run times.  I need to figure the plug to add that battery to the motors with a plug next.  I can't just use the charge input circuit , because there is always another or both on line, the old different size batt. problem.  So, I think I will need to be looking for a 3 way switch as well, and see what that takes.  I have two -- two pack switches here, probably list those on e bay, soon as I get around to doing that.  If you need one let me know.

Charlie and I cruised Dexter theother day, tried Lookout first but again too late to have usable ramps, with water drop 2--3 ft. per day going out.  A week ago I could have done that safely, but now no dock to stand on that is close to the correct launch lane.  Moved to Dexter and it was a great day.  Looks like I get two hours or close to that with two coots, thats on one pack.  One pack in reserve, as the rule.  I get close to an extra hour as a solo ride, depends on the lake, so one more pack could be welcome when I'm solo for a longer day, maybe !!!   Could do more, but at way slow voltage settings, we used 20 amps as a goot clip, and the depth finder quits when the voltage drops with a good sound to make it noticable,

Speaking of that, how about taking some runs (boat of choice)  at Fern Ridge next week, I have Monday as open at the moment.  Maybe a picnic lunch cruise, some gotta doos sort of hem me in next week, bur we haven't visited in a while.  Charlie and I came up with a formula, for a two person ride.  Water time is divided into bladder capacity, or sun power, when you gotta go, you just go pottie or usually home.  Solo runs have more options, and so need the extra battery time. 

Later,   Cal

Only two days ago had the hybrid battery replaced in my daughter’s ’05 prius she inherited from her grandfather a few months ago. It had few miles on it as it had sat for years with minimal usage, no charging save the odd time out. The batteries didn’t like that and eventually and apparently gave up the ghost. 2300 bucks installed at the Toyota dealer. Her step bro said he could replace bad cells for about 40 bucks a cell but in asking around and in my own experience I felt that wasn’t a good idea. Seen boat bank batteries in which a new battery interacted badly with old batteries resulting in premature failures.

Had the twelve volt replaced around a year ago during probate and I’m thinking it was only in the 200 and change range at the local dealer. Don’t quote me on that quote for the 12v.

Re: Electric Trolling Motors (was: Good Girl For Sale)

 

I distrust high-thrust trolling motors that run on 12 volts. I spent a bunch of good money on a fancy-dan 50 lb. thrust Minn Kota -- a good brand -- 12 volt motor, and it doesn't push Pickle along noticeably better than the cheap 30 lb. thrust motor I had before. Maybe it really only produces 40% more oomph rather than the 67% boost you'd expect from the advertised thrust, since it only consumes 40% more juice...

When you start pulling the kind of current the high thrust 12 volt motors consume you end up with loss to heat in the wires, and the Peukert effect means that you run your batteries down a lot faster. If that cheapo 12 volt 65 lb. thrust motor really does make that much thrust, it'd have to draw around 65 amps. That's a lot. A 24 volt motor would draw half the current.

I'm curious what'd happen if you ran a 12 volt trolling motor on 24 volts... I may try it on my $5 garage sale 28 lb. thrust motor. I haven't done so before because I didn't have two matching 12 volt batteries, but now I could borrow Tuffy's. :o)

Very Interesting Boat For Sale

 

THE (I think they only did one) Nexus Bolger Black Skimmer. A design I've long lusted after, ever since I forst saw it in The Folding Schooner... A very practical sort of boat.


-------- Forwarded Message --------
Subject: [TSCA-Puget] Sharpie for sale
Date: Tue, 11 Aug 2020 08:51:35 -0700
From: @mckeeb

mckeeb at gmail.com

Otter needs a new home!
$12, 000 obo

25 foot glass over plywood sharpie (Phil Bolger Black Skimmer), 3500 lbs on the trailer, 2800 lbs off. Draws 1 foot lee boards up, and ~ 3 or 4 with the boards down.

$12,000 - including the trailer, outboard and all the gear - flares, chart book, throw-able cushions, two anchors and associated rode, and etc. A professionally built Bolger boat, it doesn’t get much stranger than that. Otter, originally Ui Ipo was built in 2007, by Nexus Marine, for the original owner who passed away shortly after he took delivery of the boat in the SF Bay Area . The boat sat out of the water on his sons property. We've added a small AC battery charger, replaced the batteries (2 G28 AGMS), replaced the water pump & fresh water plumbing, and rewired the power for the outboard. The outboard is a Yamaha T8 w/ electric start and electric lift which runs well (gear and engine oil changed annually). The main (2 reefs) and mizzen were made by Carrol Hasse's loft, and I made the mizzen staysail (there's sail covers and bags too). The trailer is in good condition though has the usual electrical issues in regards to the lights. New wheels as of 2 years ago. I refinished the spars (sanded to bare wood, and applied 3 coats of cetol marine light + 2 coats of the gloss). New hull and deck paint this year. Three coats of Quantum 2 part poly. The boat is in Bellingham on the trailer.

Call, text or email to discuss.

Re: Electric Trolling Motors (was: Good Girl For Sale)

 

The trouble with "displacement" for comparison of boats is: what do they _mean_ by displacement. <sigh> Ideally, the displacement given by a boat manufacturer should be the weight of the boat with it's normal load --
the figure the designer used for calculation. Alas, what gets published as displacement can vary from the boat's weight when completely empty, to the weight when loaded to the max -- with no indication what. <sigh> But we have to work with what we can to get some _very_ rough idea about how different boats compare.

I think the crude spreadsheet I worked up a few years ago is useful, nonetheless.

https://groups.io/g/oregoncoots/files/Boat%20Design

Even though it doesn't take into account hull shape, which can have a big effect on wetted surface, which is the big part of resistance at low speeds. I've been noticing that Tuffy, because of her shapely hull and molded in keel, moves along under sail even in a barely perceptible breeze that would have left flat bottom, fin (technically) keeled Pearl dead in the water. But it would be hard to come up with a simple spreadsheet that included hull shape. <g>

You're right on the money about higher voltage having lower line losses, and lower losses from the Peukert effect.

On 8/9/2020 8:07 AM, johnacord wrote:
John,
Displacement can be deceiving when thinking about moving a hull through the water.  It's not so much the "weight" as it is hull shape which determines the size of the bow wake.  The the bow wake is created by pushing the boat through the water and pushing it requires power. Complicating this, it's somewhat exponential so that as you increase speed the power required goes up a lot, especially as you approach hull speed (top end of displacement motion).  The electric boat community has worked this out well, and as I recall the rule of thumb is doubling the power for an increase of a knot approaching hull speed.  So moderate speeds, in the realm of half hull speed, can be fairly efficient, like your "leisurely, rate of progress".
Regarding 12 vs 24 volts.  From your examples, 5 amps x 24 V = 120 watts  &  30 amps x 12 V = 360 watts;  lower watts = less losses to heating in all components.  If you are using lead acid batteries, either flooded or AGM, higher amperage cause losses due to the peukert effect which can be quite significant at the higher amperage.

John is understating the sailability of that stretch of water. The wind always blows either straight upriver or downriver. There is not room to tack so you will go wherever the river blows you, unless your rudder or centerboard Hangs up on a rock, weeds, snag, or the bottom. 

Take John’s advice.

I didn't have a GPS along, but I backed off after s short run because I was afraid I'd get a bloody nose from the speed. ;o) It did seem like Tuffy was going along at a good clip.
Alas, Minn Kota doesn't give you any useful information on their Web page anymore, or at least the last time I looked. <sigh> The _rough_ rule of thumb about their trolling motor ratings used to be about one amp maximum current per pound of rated thrust, or a half amp per pound for the 24 volt motors. Though my 50 lb. electronic controlled 12 volt motor is only rated at 42 amps. Go figure... Anyway, by that rule of thumb, the 80 lb. motor bolted to Tuffy's keel should only draw 40 amps max. If it is indeed an 80 lb. motor... Did they make larger 24 volt motors? Tuffy has an odd propeller with its tips folded, making little end plates. She didn't have it in 2017. Perhaps it's more aggressive than the stock Minn Kota prop. If the current prop is indeed overloading the motor, maybe she'd do better with the stock prop... At any rate, I won't ever be running the motor at full speed for more than a few moments, if I get in a "situation" while maneuvering.
I think I'll do some test runs with a fresh charge in the batteries, and a GPS, just before I pull Tuffy out, so I can haul the batteries home in the boat on her trailer rather than hauling them up from the dock again. ;o)

I think I'll do some test runs with a fresh charge in the batteries, and a GPS, just before I pull Tuffy out, so I can haul the batteries home in the boat on her trailer rather than hauling them up from the dock again. ;o)

Re: Electric Love

 

Did you install two of the 20 amp convertors in parallel, like we talked about on the phone? Is that OK, Bob L?

I wish you knew what the A/H rating of the lithium battery from the bike,,,

I have another converter to make the bike pack power a MKota directly also, so ready to go there too, after I get a motor to run all this stuff.  I forger how much run time the bike pack has on paper, but nees a good in water testing. It seems that the pack weighs about half a wet battery, while adding more run time, due to the lower the pack can be drained by a good deal.  Time will tell how this works out, keep fingers crossed.

Hot foot it over to a sporting gooda store, luggage store or, some even used gear places.  A folding suitcase crooling carrier works fine.  some golf carts fold but not as well.  I have a rolling insulated beer cooler on wheels, that could take a battery, plus other gear.  Think I got one or two at st Vinnies years ago.  In fact a rolling ice chest would do a lot of gear hauling for the least money, just tape the inside size to fit right.. My folding suitcase carrier needs a wood box to make work, but is the sturdiest , and folds lightest as dock.cart.      Cheaper than a chiropracters visit or two,.
