Re: D3 110i-A exhaust elbow

 

Nick,

HDI Marine Ltd www.hdimarine.net manufacturers exhaust elbows by casting in one piece using the stainless steel investment cast process. It should be a buy one-time item and is usually significantly cheaper than the OEM elbow. Many A[mel owners have purchased from HDI and HDI is a preferred vendor of Yacht School.

HDI has the following items:
Volvo TMD 22 OEM Part #3582512 HDI part #AD
Yanmar 75 & 100hp 4JH3 Part #129671-13552 HDI part #L3

Do you know the number of the D3-110 elbow? I think it is part #21192127.

image.png
Jeff Krause sent me his D3 elbow which I sent to HDI to duplicate.  I never heard back from HDI. Possibly this part is impossible for HDI to make. I will follow up today with Hailey Wilkerson, Director of Marketing, 971-255-9139, hailey@.... Anyone else needing this part may also want to write Hailey.

I see various options:

Ouch seems excessively expensive, typical Volvo rip off

Nick, My Volvo TMD22a is actually a Perkins engine ,and I have found prices for the Perkins M80 (my engine ) is less than half that it would be if I ordered the same Volvo part. If your Volvo is a Perkins ,you may want to order the elbow for your model of Perkins . I have ordered parts thru Parts4Engines , they are in the UK ,but I have gotten parts delivered in like four days.
Good Luck,

Re: Bow thruster does not work in one direction

Mohammad Shirloo
 

One method of eliminating potential sources of the problem, without any alterations or jumper installation, is to simply listen for the main solenoid activating when using the Joy Stick. If you can hear the “click” of the solenoid, when pushing the joystick to port or starboard, but the bowthruster motor does not come on, it confirms that the joystick and the control unit at the bowthruster are working and the activation signal is getting to the main relay. If the bowthruster works in one direction, then it eliminates any issues with the motor itself and only leaves the main relay as the issue.

Hello Mohammed, Doug, Thomas and Bill

 

I have just began the task of fixing my one way bow thruster, port works fine. The topic has come up many times and I had just filed the knowledge, knowing sooner or later I would need it. Well it is now later for me.

The first thing I know. This is not the first time for my 54 as I have a troubleshooting guide in with the owners manual from the previous owner. I have seen the pictures from Mohammed and the ones in the guide. My unit looked different from the one pictured disassembled, but is in fact a Sleipner/Sidepower unit made by Albright. They are similar but slightly different also I found my unit on the Vetus website.

Thanks to the legwork of group I will now remove and take apart my solenoid and hopefully I can repair and use it again. I can have one shipped into Grenada but hope this will work. I will Order one for the spares collection.

 

First I believed it was the relay but did more checking after the latest round of bow thruster talk. So I jumped the negative to the grey wire and the port direction was fine, but when jumping the blue nothing starboard happened.

I will take pictures of my unit disassembled. The inside should be similar. The two units below are the two deferent units my unit has 4 top studs also included is the part tag on my unit. The 3 stud unit I believe is the one in your manual and disassembled unit from Mohammed.

Hi all,

 

That issue happened to us 3 years ago and we reported on the solution here (06/06/18   #40108 ). 

 

 

I would suggest carrying a spare relay as it happened to us again just recently. Note that we don’t use our thruster much, I don’t know if that helped delay the reoccurrence or instead accelerated it. 

 

In our bow thruster, the oem relay is by Albright (sales@...) in the UK (they could only provide model SW202-317 equivalent to SW202-260 installed).

An equivalent relay is available at evdrives.com  in the USA.

 

 

Hope that will help,

Re: GALLEY FAUCET REPLACEMENT OLDER MARAMU

Gregory Shea
 

Hello, 
This goes back to a 2019 post, see below and I’m hoping that sharki.cigale is still on the forum.
I bought the faucet referenced below at Leroy Merlin and have been anxiously waiting an opportunity to instal it. 
It seemed quite easy but I have run into a problem. The threads on the new Mitigeur are longer than the threads on the old one so that the discharge from the new one does not align with the vertical pipe that delivers the mixed water into the sink.
When you did your installation did you also change the hot and cold inbound plumbing coming through the plywood trim?
I bought the other adapters you mentioned and I’m wondering if they will correct the problem, although they don't seem compatible with the plumbing behind the trim?

Re: Self introduction and question about autopilot redundancy and solo sailing

rossirossix4
 

Almost always we are sailing as a "Ma and Pa" team and auto steering is pretty high on our list.  We are most concerned about lightning.  A lightning strike could easily take out both of 2 installed units even if one unit is turned off.
For that reason while we carry spares for each AP component, none of the spares are installed.  So we carry matching components for our autopilot--control head, fluxgate compass, course computer, rudder feedback and linear drive (we do not carry a backup for our switchable rotary drive). Each is sealed in ziplock storage bag with dessicant and the linear drive is well wrapped.  They are stored in lockers away from other wires and rigging attachments.  Determining which component has failed is not hard to do and swapping components is not difficult.  It is helpful to label each wire, especially to the course computer/power source.  We have not done it but the best thing might be to replace all the replacement components and store your existing components.  That way you know the replacements work and you have experience installing them and doing any initiation.  We also have some provisions for power if the batteries get zapped but I won't go into those details,

Re: mounting 12" chart plotter

Arlo
 

I took a different route and happy i did. I installed a 7 inch zeus in a navpod at the helm offcenter to port and installed a 12" zeus in a navpod on the starboard side of the companionway. It preserves the use of the existing gauges and gets larger plotter and radar screens so its not blocking my view forward. I use the smaller display for sailsteer, and backup chart views and autopilot. Imho a perfect setup. Will post pics in a seperate post


Re: No steering parts, rack & pinion, cables, from Amel

I recently installed a B&G ram 2 and rhe associated autopilot on my Mango. It has run flawlessly during my Bahamas cruise this past season. I have not decided if i want to secure the ram with a seperate bolt to the quadrant or continue using the cable steering bolt.....but it is mounted to the aft stringer with a 6" L beam that is 1/4 thick.

Re: Bow thruster does not work in one direction

Doug Smith
 

Randall, If you are not getting a Starboard movement with the jumper, than the problem is Very likely in the solenoid you have pictured.  By using the jumper you are bypassing the delay circuit that is inside the control module and most of the other variables.  As Mohammad found, it is likely corrosion of the contacts inside the solenoid.  And as Bill preaches, liberal corrosion X serves as a good dielectric coating to help prevent corrosion and ensure good contacts.

I do not believe it is reasonable to expect one (or even two!) people to hand steer a boat for a thousand miles.  It just gets mentally and physically exhasuting, depending on point of sail and weather.  BUT>>> there is an alternative as Thomas of GARULFO suggests.  A well balanced sailboat (and a SM is pretty good at this) can sail on it's own for a good long time, holding a more or less constant angle to the wind.  It is very effective upwind, moderately so on a shallow reach, and is difficult to impossible as you come further downwind. You can not go anywhere you want to go, but you are not helplessly drifting either.

There are a few tricks.  To get a SM holding a steady course you must trim the sails so there is a bit of weather helm.  If there is even a bit of lee helm the boat just will not balance. In light winds, sometimes the mizzen traveler needs to be cocked to windward a bit to get the rudder turned the right way. The boat needs to head up in a gust, not bear away.  Off the wind, sheeting the jib in a bit loose, and having the mizzen just a bit tight can help.  The boat won't hold a dead straight line, but it will find its own way.  

When sailing close hauled, the rudder needs to be locked in place, as you bear away, there comes a point where the boat will usually behave better with the rudder left free to find its own angle. in both cases, if the need existed, this could be handled by the emergency tiller.

Minor course adjustments are made by tweaking the angle of the mizzen.

On our old boat (a 40 foot ketch) we broke our wind vane 1/3 of the way from California to Hawaii.  We managed 650 miles back upwind to California just trimming sails.  Once the boat was in the groove, we made course adjustments with the mizzen sheet.  We hardly touched the wheel at all until we were back in the variable coastal winds.

Each boat, and each set of sails, has its own sweet spot.  The only way to really know is to practice it. Having a powerful, reliable electric autopilot covers up a lot of sail trimming sins. Learning how to balance the boat so she can take care of herself will make anybody a better sailor.

We have the linear drive installed on our rudder, the chain drive on the wheel, either one can be driven by either of the two autopilot computers, and we have a backup linear drive that drops in place easily.  But of course all those do depend on the constant supply of electricity.

Hi Thomas, I agree with you. Seamanship is something that has been forgotten in this age of electronics and perhaps we should relearn it.

In our experience there are points of sail where our boat can sail itself for a remarkable long time (upward of 45m) with the helm completely free, and that despite of confused seas.
We’ve done it for fun in the Caribbean and again in French Polynesia, in between islands, with AWA between 60° and 40° and AWS of 12kn to 18kn. 

I can’t really say why it works so beautifully but once the sails are trimmed properly (the mizzen being the final touch to perfectly balance the boat), the sea state is absorbed by the free rudder. The helm turns a fair amount as the boat rides up and down the waves, but it behaves better than when driven by the autopilot. It’s a smoother ride, more natural (and very satisfying!).
It usually stops when an odd wave pushes the boat out of equilibrium and the AWA start drifting one way or another. 

I don’t know about other points of sail. I’d say it’s more difficult to achieve as the sea is more likely to knock the boat off balance. 

I would imagine drifting/heaving to is a way for solo sailors to rest.

Having said that, I think the redundancy you are looking for here is crew. 
Solo sailing such a big boat requires reasonable confidence that redundancy of technical equipment will cover 99% of situations. The remaining 1% is a leap of faith. If that is not acceptable, a smaller boat with a wind-vane may be a better choice.

All valid comments and thank you for your inputs.

How is it humanly possible to manually steer a boat for 15 or 20 days if you're on your own and for exemple having to deal with a complete electrical failure ? 
I'd like a fail operational system but I know this isn't an airliner and event they sometime fail despite all what is done to achieve redundancy.

However I'd like to do my best not being on my own in the middle of the Pacific Ocean having to manually steer the boat ....

So here we are :
1/ How can we have a backup automatic steering in case of total electrical failure ? I was of course thinking of a wind vane system but I've heard this is not achievable on a SM/SN is that true ?
2/ How can you reasonnably deal with the said situation if you don't have such a backup ? Can you still setup a bungee system which would "steer the boat" while your'e having the little sleep you need not to kill yourself ?
