Hi Arno,

 

Indeed it seems both of us have spent/are spending a lot of time, energy and money to get our boats back in shape.

 

There are two relays/solenoids behind the white panel near the ceiling next to the closet in the guest cabin. One of them is for the main outhaul (we had to renew that one last year) and the other one I guess is for the main furler.

 

I really think it is either the switch (we think it is good); the relay/solenoid or the bushes as: A) I can furl in with the motor and B) the furler itself can be hand cranked. BTW you need a short handle o'wise you will not be able to make a full turn due to the outhaul motor cover.

 

I should have tested all furlers b4 leaving port; but everything was working perfect 7 days ago coming back from ISLE des PINS. I guess another lesson learned.

 

How are you getting along with LUNA?

 

Best Regards Teun

Hi Teun,

 

Your boat is really keeping you busy, not?

 

For your problem I think you have two possibilities. A relative good one and a bad one.

 

The good one is that the relay is not working for whatever reason. I’m guessing the relays are near to the circuit breakers in the guest cabin (see attached circuit diagram).

The second possibility is that there is so much play on the gears inside the gearbox of the furling motor that they lock-up causing the motor to stall.

 

My first guess would be it is the first problem, maybe caused by a broken wire or contact corrosion.

Bill,

 

I knew of these 2 boxes but was not aware they were the solenoids; I thought they were resistance breakers.

 

I will have it checked by Willie this morning. From everything it sounds the bushes might be likely the issue as it furls in no problem; when the motor released from the furler we can hand crank easily.

 

Will let you know the outcome today.

 

Thanks for the help.

Furling solenoid is behind the Velcro'd panel just inside the forward watertight door near the ceiling, or behind the Velcro'd panel in the forward port side berth.  I don't think this is the problem, but Willie should check it and the helm mounted toggle switch.

Thanks Arno,
I switched wires on the relays to one of the working motors and got the same symptoms. I am going to remove the motor to take it apart and inspect gears and brushes. Fortunately I found a whole bag of replacement brushes in the piles and piles of spare parts that came with the boat. If I need to there is a local company that rebuilds electric motors at a reasonable price.

try the mallet Bill suggested. 

Mine played up in Antigua last year. 
If someone stands near the solenoids, you will hear them click if they are working. If they are power is going to the motor. My motor responded with a gentle tap. The problem was the brushes sticking in their guides because of carbon dust. A good clean sorted it out. But make sure you surround the motor with an old cloth. Carbon dust and a bit of water make a nice mess if the deck.

I have two Rutland 1200’s on Amelia and two 275w solar.
For the money the solar payback is a no brainer. Money well spent.
As for the WG’s. The payback is poor and although the blades are silent there is a resonating hum that is annoying at night in the aft cabin.
However there are occasions whilst on passage, when it gets a bit rough and the autopilot is working hard, maybe it is raining and the visibility poor and the radar on 24/7 plus all the navigation instruments. When one would normally be pulling 15A out of the batteries. That they come into their own and really chuck out the power such that the batteries just stay full.
Would I do it again......Probably but if money is tight no.

I have had very good experiences with my Superwind half way up the mizzen mast.  It substantially contributes to balancing the power needs on Kincsem on most days without anyone noticing it is there.  My 400 W solar usually contributes more here in the Med, and when offshore, my Watt & Sea blows them both away, but in my view it’s all about alternative sources.  Wind is great at anchor particularly in the Aegean and sailing on all courses other than a broad reach or downwind.

Re: 100 amp charger on sm2k

David Vogel
 

Greetings all,

 

I have a top-of-mizzen Rutland 1200, installed 2018, cost to purchase-and-install ~$2,200-. The running count for the wind-gen since it was last reset 920 hours ago Arriving on-anchor, La Playita, Panama), is 547Ah contributed to battery charge; =~ 0.6Ah per hour, =~ 15W average per.hour contribution.  Since last reset, we have been in a typical steady wind, but not-so-windy location.  Previously, when in windy locations (meaning, wind in general blowing always 18 knots, but often 20-30), we were seeing easily double, sometimes triple this, on-average.

 

These overall production figures are somewhat BELOW what would otherwise be seen in a stand-alone wind-gen set-up (without solar), because at mid-day +/-2.5H when your solar cells pumping it in, or when the batteries are sensed as fully charged, the wind-gen switches off.

 

Also, when you are on genset (or motoring), sometimes the wind-gen senses this and shuts down also.

 

But when the wind-turbine is spinning, the output is within 5% of the manufacturers curve (case: windy at night, no solar in competition, for example).

 

Overall, with the solar and wind-gen, my need to run the genset whilst on anchor is reduced to about 50% of what is was before (no solar or wind).  On longer offshore passages, we have only a few days here and there, so not really able to say.  So I am still planning fuel burn for offshore work on the pre-wind/solar basis of 2 x 1.5 hour genset runs per day.  I am happy with ‘free’ power from the shaft gen – enough to cover the NAV Station – when STW >7 knots.  I switch the shaft-gen off if I really need to squeeze for speed, as I estimate that the shaft-gen pulls the STW down by between 0.5 and 1.0 knot. For really long-distance work (say, >3,000nm), that 1knot pull-down relates to an extra 2 days passage-time.  There is always a trade-off.

 

I am glad to have the redundancy provided by solar and wind in combination, although this is only partial at best.

 

We are not at this time considering a second wind-gen.  We are thinking to increase the solar to 800-1,200 watts.  The panels themselves will pay for themselves over time, but the capital expense of the arch is harder to reconcile.

 

Cheers,

.......am sure your right Bill unless you live in the roaring 40’s and do most of your sailing in higher latitudes!!  
The Rutland wind mill having sailed from the Med to NZ lost its feathers in gusts of 45 to 55 knots off Kaikoura on the west coast of the South Island. It was replaced with a silent wind generator which, while expensive, has been excellent at maintaining power levels in the batteries and has a built in breaking system

Re: 100 amp charger on sm2k

Mark Erdos
 

Kent,

 

I have to agree with Bill. We have a wind generator, it came with the boat when we purchased it and then broke. We replaced it with a clone but probably should have saved the money for something else that hasn’t broken yet.

 

If the wind is blowing 20-25 knots consistently it is worth it. But how often does this happen? At this wind speed it will put out about 5 amps per hour and help during the night when solar panels are sleeping. It is just enough that I do not have to run the genset in the morning to top off the batteries until the solar kicks in (we are running all three ref/frz).

 

You can do the math for the number of days you spend per year cruising, the number of days you will have ample wind and compare to the cost and wear on the genset running we you need the extra omph. My guess is you will find it is not feasible.

 

Right now we have winds of 5-10 knots and it is the same for the rest of this week. We are on the hook and the wind generator is totally useless.

 

If I had to do things over, I would add more solar and increase the size of the battery bank

 

With best regards,

 

Mark
