Hi Bill,
On page 30 of your excellent ( May 2019) Amel book appears a photo of the drive arm which connects the gearbox to the Andersen winch. On that arm is a bronze bushing.
Can you explain where this bushing fits ? Presumably it is not part of the gearbox ? Does that mean that it sits in the boom itself and helps to keep the drive arm in place rather than placing all the stress on the bolt which attaches the drive arm to the
winch?
The reason I ask is that since my drive arm was replaced in 2009 the four bolts attaching the bearbox to the bracket on the boom have worked to elongate the holes in the bracket. I am about to dismount the boom, detach the arm and gearbox and have a new floor
fitted to bracket with new holes drilled. I am half expecting to find that when the drive arm was fitted in 2009 ( no names mentioned--but it wasn't me ! ) the bush was omitted and that has resulted in the wear on the bracket.
Anyone else had a similar problem ?
Ian and Judy, Pen Azen, SM 302, Kilada, Greece

Re: Ground strap in bilge
James Alton
Bill, I also considered using wire for the bilge bonding but I liked the idea of the heavier copper bar that you suggested and went that route. I think that wire or a thin strap is pretty easy to damage over time with bilge cleanings. I covered my new copper with very heavy glue coated shrink wrap which hopefully will make it last even longer and no sharp edges. The stiffness of the thicker bar also made it easy for me to place the end of the bar on the keel bolt and to hold orientation as the keel bolt was tightened.

Re: Ground strap in bilge
Dean Gillies <dean@...>
Alan, I believe you have hit the nail on the head. It’s all about the resistance at the joint to the bolt. A wide flat strap provides the maximum surface contact area between the strap and the bolt. That is the most effective way to minimise the resistance at the joint. A thicker flat strap (than the original) will provide similar resistance (when properly installed) and better longevity. I’m not looking forward to this job when my time comes, sounds really awkward! Dean SY Stella A54-154 X

Re: Back up tablet navigation aid
We have Furuno Navnet II at the nav station and at the helm, networked with C-Map charts, Laptop at the navstation with MaxSea TZ and Navionocs and C-Map charts and OpenCPN with Google Earth satellite charts plus WiFi connection to a tablet at the helm to mirror the laptop. We also have a B&G plotter where the Forward sonar used to be, with Forward Scan and Navionics charts. Our experience in the S Pacific is that the C-Map charts are generally good, Navionics less so, especially in Fiji where Navionics sometimes doesn't show passages where they exist and shows reefs where there aren't any and doesn't show them where they are.
In the S Pacific ALL electronic charts suffer from the fact that a lot of them are based on very old paper charts made before WGS 84 datum and while thay can be accurate to look at , things are not quite in the right place. In New Caledonia and FP we found the electronic charts to be precise. In Tonga miles out, Fiji a bit out, same in Vanuatu. Mark 1 eye ball is the best navigation instrument in close quarters.

Re: Ground strap in bilge
The fact that it is only milliamps makes the conductivity very important. Even a slightly bad connection at the keel bolt will make the keel rust. Best to use 3mm flat copper bar to make the best conductor for the bonding system.

Re: Volvo TMD22 Timing Belt

When Bill recently did the timing belt on our engine, he used a good belt tension gauge, and a dial indicator to re-time the injection pump. He also replaced the tension and idler pulleys. They weren't expensive, and are critical bearings that are really easy to change while you have the belt off anyway.
If you look at the shop manual, one of the last steps is to reset the timing of the injection pump. That is an important step that people seem to frequently skip. The camshaft and the crankshaft are locked in place (6mm bolts work as well as the $pecial pin$ from Volvo!) and as you tension the belt, the shaft of the injection pump will rotate--at least a little bit. If you don't reset it, fuel injection timing will be off, and that is a bad thing. Late injection will result in unburned fuel and reduced power, early injection can seriously damage the engine if the fuel ignites significantly before TDC. The adjustment is a little fiddly, but not hard. It might be our imagination, but it sure looks like we accumulate a lot less soot on the hull after this job. Could fine tuning the pump timing have helped with this chronic problem? This is a very important project on these engines. If the belt breaks or gets loose enough to jump a couple cogs the valves and pistons will hit each other and in seconds your engine turns into a very expensive mooring anchor. It's worth doing better than just eyeballing the belt tension, which is really high and quite hard to do by feel.

I am sitting south of Barcelona. One group member put me onto a German supplier, a former AMEL owner is trying to source it out of Britain and I have been told AMEL does still have them.
Glad I joined this group.
And Bill I agree that the original are way too thin.
I love my boat,

Amel uses a thin copper foil for the bonding strap inside the gray water bilge. In terms of electrical conductivity, it is perfect. In terms of durability it is not good enough. The gray PVC float switch tube sits on top of the copper foil and
will wear through the copper foil in a few years. If you buy the Amel OEM copper foil, I suggest you buy 2 because you will likely need to replace it again in a few years.

Re: Mizzen mast paint.
Patrick McAneny
Paul, I painted my main mast with alwgrip ten yrs. and it was a perfect match. I just sanded it with 320 grit and then roll and tipped it , I did not prime it other than a few spots where I had corrosion. Having the boat repainted this winter due to a 47' cat who drug anchor and hit us at 4:30 am. in Guadeloupe . I will try to determine the paint color and get back ,need to anyway as I plan to paint the mizzen mast and the booms since I will be demasting the boat to go into a shed for painting .
Pat,

Re: Back up tablet navigation aid
Joerg Esdorn
I have Furuno Tz as the main system using C map charts. I do all routing on a laptop Interfaced with the Furuno and running the same charts. I’ve come to appreciate Navionics app and charts on my iPad because it often provides additional detail on anchorages. But cmap charts are sometimes more accurate as well. So bottom line is: two separate systems is a good idea. I like Navionics generally but any app on a tablet is no match for a real computer when you want to build a route. For serious weather routing you will need a laptop anyways.

Hi Bill what’s your thoughts on using copper wire, instead of the strap. Will this provide enough electrical conductivity?

Re: Ground strap in bilge
This bilge bonding strap conducts micro volts. Stainless steel is much, much less conductive than copper. If I remember correctly, stainless steel has about 2-5% the conductivity of copper. Additionally, I had a client/engineer fashion one out of 1/8" x 2" stainless steel bar. He told me it was very difficult and to warn others that it wasn't worth it.
