Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
Mike Longcor (SV Trilogy)
Hi Alex,
My understanding of the anti-siphon on the raw water line (between the exit from heat exchanger and input to exhaust elbow), is to prevent continuous water flow (after engine shutdown) through the intake line should something in the line break/leak/disconnect/etc. The design of most raw water pumps prevents this continuous flow as long as the vanes of the impeller are intact. The flow of water out of the anti-siphon while the engine is running provides a good visual check that 1. your anti-siphon is working and not clogged and 2. that your engine is getting a good supply of raw water for cooling. I'm not sure I follow Oliver's comment about water standing above the engine for long periods because I'm pretty sure the water would find it's way down to the muffler with or without a siphon break at the top. Again, this assumes your raw water pump/impeller is fully functional, and those certainly fail from time to time. So a working anti-siphon is a good way to ensure your engine doesn't flood and/or your boat doesn't sink. I may be wrong on some of this so if anyone has any other input please share. Also... I'm still searching for any information on the rubber anti-return flap at the end of the exhaust line near the through hull. Has anyone bought, replaced, or fabricated something like this for their Amel? Regards, Mike SV Trilogy - SM23 Opua, NZ

Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
I'm not sure I fully understand this quote from Oliviers post:
" Last point, the anti-siphon system cannot prevent water from getting into the exhaust line. It is designed in order no water can be sucked from the intake line, and once the engine is off, in order the line drains into the muffler, and water does not keep above the engine for a long time. This is also a check point (does the water drip out of the cockpit while the engine is running?)". Can someone help to interpret please? Jamie, in case you read this, can you tell me whether or not water from high waves made it into your cockpit? (..and filled your drain and eventually the small hose that goes from inside the big drain tube to the round metal hose in the engine room (metal part of the system that is attached to the Diesel tank). I had water in my cockpit and I consider the possibility that the water made from the big cockpit drain through that small hose and from there into the motor (possible if water is high enough in the cockpit in combination with the boat moving in the waves.

Re: Grounding for solar panels / solar arch
Patrick, zincs that are eroding is a good thing. That means they are providing protection as they are supposed to erode. It's when corrosion/erosion shows up elsewhere (for example, a pump impeller) that you have a problem. That means that the pump is not protected by the sacrificial anode. As for the macerator pump on your heads, I thought those motors were already bonded. Seems to me I saw a bonding wire on mine, although I'm not on my boat right now.

Re: Super Maramu Main Mast Furling foil Sheered

I had not seen the photos ,I now see that the sail groove would keep a sleeve from rotating within the foil,I still think I will mill it from solid stock and mill it to fit around the luff groove.
Thanks,

Re: Grounding for solar panels / solar arch
Patrick McAneny
I have wondered ,should the electric motor on toilets be bonded? They have contact with the sea ,don't know if any metal parts are in contact though,like the impeller shaft. My zincs are eroding ,so suspect I have a leak somewhere. Can electric flow from a toilet back to the sea through the hose to the seacock?
Thanks,
Pat

Do the metal parts in the exhaust systems qualify for bonding as well then? The muffler on my main engine is metal and the fittings on the generator's nonmetal muffler are also metal. The engine's muffler is bolted to the angle-iron frame, so maybe it's already bonded? I will check. Or perhaps none of this counts as these metal parts and the seawater in contact are isolated, not connected to the rest of the ocean or other parts of the boat? I don't think it would hurt to bond them... would it? Appreciate the help. Thanks, Mike SV Trilogy - SM23 Opua, NZ

Re: Super Maramu Main Mast Furling foil Sheered
Patrick McAneny
It would seem to me that a bushing or sleeve slid up inside the foil would need to held in a fixed position relative to the foil ,otherwise it would be free to rotate within the foil and not take pressure and wear off of the foil itself. Preventing the sleeve from rotating with the foil could probably be accomplished either by coating it in epoxy while inserting it or by installing a second bolt 90 degrees and slightly above or below the original bolt ,drilling a new whole through the foil and sleeve. I will have to check for this problem that until now did not know existed , this is yet another example of the value of this site. This could be a real problem in heavy conditions ,for this defeats the manual furling ,necessitating taking the main down at sea in strong conditions. I am getting ready to drop my masts in preparation to put my boat in a shed to have my boat painted, and will preemptively do this repair . I think a solid aluminum plug may be the way to go .
Thanks for the heads up,
Pat McAneny

I have a similar problem.. the passerelle tubes slowly ground through on a concrete dock without us realising when wintering in Spain. I've temporarily glassed them up but could do with getting some new ones made as the weld on the steps are also failing. Did anyone find the passerelle plans in the file section, because I've looked and they don't seem to be there - unless I'm looking in the wrong place?

Re: Mobile communications - 4G, WiFi
I have found in the Med, Canary Islands and the Azores that 4G works very well and fast. My UK phone package makes it very inexpensive within the EU. So the phone can be used as a hotspot.
toggle quoted messageShow quoted text
Whilst in Turkey, the EU deal is not available so I use a MIFI device. I buy a local data only sim card. This too is very inexpensive and offers fast broadband. I have also used this MIFI device with locally purchased sim cards, in the West Indies but I found that the 4G was very slow and that each country has a different provider (2017-18). So whilst sailing up or down the chain of islands one moves pretty quickly from country to country. Of course the French islands benefit from the EU deal. In conclusion I agree with Woody, that I can not be bothered with running more hardware on the boat, but I guess it depends where you cruise. There may also be a security argument against piggy backing off local public wifi spots, such as bars and restaurants, even marinas. As a UK resident I hope that we continue to benefit from the EU negotiated mobile phone deals post BREXIT! I guess it is up to the network providers. Nick Amelia AML 54-019 Kilada Greece.

Re: Grounding for solar panels / solar arch
Mike,
The deal is any metal that is in constant contact with saltwater needs to be connected to the bonding system. If you have attachments, as you say, on your non metal muffler, they will not need connecting to the bonding system as they are not in contact with saltwater. You should be able to decide what needs bonding and what doesn't based on the first line above. You can check if things are bonded or not with a multimeter, one probe on the main bonding connection, or something that you know is bonded, and the other probe on the item in question. Good luck Alan Elyse SM437 If it's bonded you'll read continuity on the ohms range, ie very low resistance...if it's not bonded the reading will be open circuit or maybe many megohms.

Re: Mobile communications - 4G, WiFi
Alan "Woody" Wood
It’s definitely worth trying first before shelling out loads of money and running wires everywhere. Things are only getting better and cheaper with mobile networks too. We anchor 90% of the time during summer and most of that time we get 4G.. occasionally 3G. Coastal sailing too is never usually a problem.. sometimes we even get coverage 20km out! The thing is to find a sim plan that covers all of Europe and costs less than €1 per Gig. Some ‘unlimited’ plans have caps on ‘roaming’ outside your native country.. so check the small print. Our plan is UK address only but i’m sure there must be others out there.

Re: Super Maramu Main Mast Furling foil Sheered
Graham Boyd
Thanks everyone for the quick replies. I've owned Sula for 15 years now and pretty sure this repair wasn't done by the previous owner, so looks like it should be reasonably straight forward. Ten years ago we bought a new mainsail with small vertical battens from Deme Voils. Although through great care, we have had very few jams over these years, one does have to be quite disciplined in the manner one furls and unfurls compared to the non battened sail. Despite that we won't be going back to no battens at the next sail renewal.
Given her age and the huge amount of use our boat gets, a failure like this should probably have happened a lot earlier! Graham SM140 Sula Hong Kong
