Gear position when sailing and propeller drag freewheeling vs locked

Craig Briggs
 

Hi Attilio,
Although we've switched to a feathering prop, isn't there a little plaque in front of your gear/throttle control that says (in French) to shift into reverse to lock the propeller when sailing?  After shutting our engine down we shift to reverse briefly to be sure the prop feathers to its neutral position, and then shift back to neutral.
Also, although this is a recurring point of debate on discussion boards, here's a link to a recent (2009) academic engineering study of typical sailboat propellers that shows quite dramatically that the drag (advancement resistance) is much less when the propeller is free wheeling. With a three-bladed fixed propeller at 6 knots the drag is some 3 1/2 times greater when locked than when free-wheeling. 
That said, the noise is annoying unless you're generating electricity, so locking is probably the choice. I susoect wear issues on the transmission, "C" drive, and shaft seals are pretty minor.
Cheers,
Craig

Hi Rainer,

partly agree with you on the need to allow the propeller to be always free to turn when you want to have power from the shaft generator. 

I have the same on my Santorin. I have to change the "bague d'usure" this year for this reason.

I was wondering if it is possible to stop the propeller, maybe with the reverse gear on? For a mysterious law of physics, it seems also that the advancement resistance is less when the propeller is not turning.

From S.P. Radio A/S, Aalborg, Denmark.  The manufacturer stated these units were very low noise and ideal for powering radios.  Working perfectly, we took two out of Peregrinus last week.  One was dedicated to the Amel chain counter and the other to the original Furuno VHF; previous owners had tacked one or two devices on top of the originally intended purpose on each, but these two always had very light loads.


Interestingly enough, S.P. Radio stipulates these units must be mounted vertically and upwards, yet Amel installed them vertically and sideways; and still the units performed for over 12 years and still work!

These two have been replaced by a Victron Orion DC-DC converter which has as a backup a Mastervolt DC Master DC-DC converter in case the Victron ever gives up the ghost.

The manual, on .pdf, I can e-mail to anyone.  8A @ 12V max.  The documentation includes the electronic diagram and the parts list so the units can be repaired in the field if they ever fail.

Anyone in this forum wanting one, just ask for it via e-mail and send the cost of shipping to your location.  First come-first served.  The address is svperegrinus at the company that provides this forum dot com.

The other one is going on eBay.

Hi,
I clean out the last water from the bilge with a sponge tied onto a suitable length rod If you repeatedly fill with water and empty the bilge with the pump several times first it dilutes the filth a bit before you have to squeeze the sponge. It only takes a few minutes to dry the bilge by this method.

Hello,

Looks like our electric systems on Super Maramu 2000 #350 are currently ungrounded.

We spent a most wonderful afternoon yesterday exploring our bilge or sea chest in the engine compartment.  Here is what we found hanging or attached to the forward bulkhead and usually hidden by the bilge pump float+switch cylinder we removed:

1.  Grounding wires meld/union
Hangs from about 8 grounding wires coming from port and starboard near the top of the bilge pump’s high water mark.

2.  Grounding strap joint to the wires
Hangs from the meld or union

3.  Grounding strap loop
The strap does not immediately hang to the bottom of the bilge.  Instead, it hangs loosely from the above structures 1. and 2., and then loops back to the forward bulkhead.

4.  Grounding strap attachment to the forward bulkhead
This is well below the bilge pump’s high water mark, and therefore is submerged most of the time.  Covered in muck, we did not see what does this attachment consist of.

5.  Grounding strap extension to the bottom of the bilge
The strap hangs from the above structure 4. and ends an estimated 20 centimetres (8 inches) before it reaches the bottom of the bilge.  The end does not look like a clean cut and instead looks ragged.

We tried to fully evacuate the bilge but were unable to remove the final 2 centimetres of water (1 inch) to see if we could spot the keel bolt at the bottom.  As the water is pitch dark, we were unable to see the bottom of the bilge.  We used two different manual pumps, but no matter what we did, a bit of extremely dark water/muck remained.  We dropped a gallon of vinegar and left it overnight, and plan to use other chemicals and brushes to see if it is possible to see the bottom.

Cheerio,

Re: [Amel] Battery Plan for Amel 54

Hi Rainer,

The previous owner purchased a hydrovane (thanks bob...we love our boat btw) and although there has been much discussion on its effectiveness on this forum mostly from SM owners (it might be two small to handle the SM) we are thinking that we too can get away with not having to use a generator.  I know of only one santorin that had one installed. 

I will say that you might be the only SM owner that doesn't use their onan on regular basis!  I have heard the same complaints form other duo gen owners.  They say it is a great hydro gen. 


Re: [Amel] Battery Plan for Amel 54

ericmeury@...
 

Attilio & Maria Siviero

I usuall keep the santoin in reverse when sailing as we are not using the shaft alternator yet.  Maybe joel can chime in here...but if there was risk to the gearbox why would amel intstall this....Is there a pump to move the oil around or does the prop turning by sail move the oil around   and if so what precautions should owners take to make sure everything functions for as planned.  - and how often have you had to change your wear bearing? and do you think that is because of the prop spinning.

Bill..

Your post is great.  Does anybody know if the measurements are the same, Ironically i have a metal guy that owes me some cash so i might as well have him make me a few of these to keep on the boat.

There are 2 items that are a must on an Amel. A wet dry vac. and a pressure washer. The pressure washer can be bought any where and fits on the end of your regular hose. This 3 foot long pipe goes to the bottom of the bilge and blast all the crud from the sides and bottom of the bilge. Take  the filter off the wet dry vacuum and tape a plastic 3 foot long pipe on the end of the hose to reach the bottom. With numerous fill ups and washing, the bilge will be like new. I found a great pressure washer(haven't bought it yet). It even has a container for soap and can go from heavy to light washing. Great for the engine room.

Francisco and Odette,

 

I did exactly what Bill describes below. Thanks to his measurement and instructions, I was able to prefabricate the replacement copper and then install later. The installation will only take a couple of hours. You will find the existing copper is attached at the keel bolt, about half way up with a screw that is inconveniently located just out of arms reach and a screw at the top.

 

In addition, I also trimmed and replaced the lugs on the ground wires attached to the copper. I did this to ensure a nice tight fit onto the new bolts I installed in the replacement copper. I also added heat shrink tubing to waterproof the lugs.

 

Thanks to Bill’s previous posting on this topic, I was able to detect that the grounding strap was breaking before it was completely in two parts.

 

Best regards,

 

Mark

Francisco and Odette,

  1. You need to review the photos here: https://groups.yahoo.com/neo/groups/amelyachtowners/photos/albums/138287824
  2. You should have a wet vacuum aboard...in the US we call these wet/dry shop vac. This is about the only efficient was to completely clean out the bilge sump. You will also find it handy when opening any water line or changing impellers. It can be used to suck the impeller blades from the heat exchangers.
  3. The issue with the ground strap installed by Amel is that it is susceptible to any/all chemicals that end up in the bilge. Some of these things will deteriorate the braided copper that Amel used. 

I suggest a 1/8 inch or about 3mm solid copper strap as shown in the photo. You will also need a 30mm socket and socket drive extensions totaling about 80cm to 1 meter. With all of the bends and measurements included this is not a hard job.

Thank you, Bill. Proves to me that sailors are the best people, and it appears Amel Owners cap that list as well. Joel has SM#477 available now, unfortunately that is about 14 months earlier than I will be buying. Thank you for the info on the charging. I am sure you will be reporting to the group on your empirical findings once you get going. I would love to look at the excel file, but really, it would be so much hieroglyphics right now until I get hands on. But thank you.

I am enjoying reading your Blog. Very good writing! Thank you.  It is blogs like yours that keep me going. Sometimes, sitting in bumper-to-bumper traffic, I actually feel like I am drowning!

Try using a wet-dry vacuum to get the last bit of water out.  I had to replace mine a few years ago, as the bonding strap had completely corroded away.  With my new electrolytic prop shaft damage that is the first place I will look for improper bonding problem.
