I believe you have a ground solenoid problem. Check the tightness of the terminals on the ground solenoids. I have seen this happen before. Fair windsOn Mon, Aug 11, 2014 at 4:42 AM, crwggb@... [amelyachtowners] <amelyachtowners@...> wrote:

Re: [Amel Yacht Owners] Volvo TMD22a Intermittent electrical failure causing ...

Graham,
You have not said whether or not you load-checked the starting battery to see how many Cold Cranking Amps (CCA) are available. I think that you need to either have a battery guy come to the boat and check the starting battery with a digital battery tester, or buy the SOLAR brand digital battery tester (from Hong Kong)...search photos or conversations for "battery tester" or "BA7." If the battery does not much amperage available, the turning of the switch OFF/ON will have a positive effect because the contacts on those switches do get microscopic corrosion (search Conversations for CorrosionX). The battery cable connections and battery terminals will also get the same type of corrosion. Corrosion reduces the amount of amps delivered to the starter...more corrosion, less amps. Good voltage will only tell you that the battery has been charged recently and that there is probably no internal short. The CCA should measure at least 700 to be able to crank the engine or Onan because of the size of cable and length of cable, and there should be minimal corrosion on all connections and contacts. I recently bought 12 new batteries and the CCA was below specs of 850 on 2 of the the new batteries...yes, it happens and if you do not test new batteries when they are delivered, you may be disappointed later. I have a digital battery tester. When the batteries were delivered I sent 2 back. The vendor returned with 2 fresh batteries that tested good. FYI, when I replaced the 13 batteries, I bought 12 of the GRP 31 size deep cycle batteries. I also bought an extra large 170 amp/hr 1000 CCA wet cell truck battery and installed it as a starter battery (there is extra room). It makes no sense to me to have a deep cycle battery as a starter battery. I also added a small 230V 6 amp charger for the starter battery. I hope some of this helps you...if you are like me, you must really hate battery issues!

Hi given the problem seems the battery cables. Check the battery cable ends to be sure to either take the battery cable itself is in good condition. They have corrosion inside the battery cable. Therefore it will not carry the load when you tutor the key. Regards Capt Richard Piller On Aug 11, 2014, at 6:42, "crwggb@... [amelyachtowners]" <amelyachtowners@...> wrote:

lewmar hatch on a 54
JEFFREY KRAUS
I'm looking to replace the hatch in the saloon. It's leaking. The main weather stripping is shot, and the opening brackets which also lock the hatch in position when open are working poorly at best. Has anyone replaced this hatch? The actual replacement "appears," to be the lewmar medium profile hatch (24&11/16 square cutout). There is also the ocean 70 model, which has the same cutout. This is listed as a flange base, or a flat base. The trim kit is only available with the flat base series, so that would be the model of choice. The ocean 70 model is about $150 more. Any feedback is appreciated. Jeff Spirit Amel 54 #12 |

Re: [Amel Yacht Owners] Re: polar diagram
Ric Gottschalk <ric@...>
Look into "secants". Hard to find in any cruising books. It is a method to sail the fastest speed in the least distance given the parameters of the Boat. Simple example is a multihull that sails much faster off the wind than downwind. Covers more ground, but the vmg is better. Frances Howorth of Super Yacht News in the UK and holds an Ocean Masters License told me "nothing goes to windward better than a 747" Many sensible people (often wives) "meet" the boat when conditions suggest it or take extra crew for safety.

Re: polar diagram
Jacques Paulus <jacquesetannick.paulus@...>
You’re right Dave,
I’m now 63 and I’ve learned sailing without computer, without GPS, without radar, without AIS etc…So, today I continue to sail with a long experience behind me, but…I appreciate all those new technologies to help me in taking the right decision. It also help me to take decisions that I would have difficulties to take without the information those new technologies can give. At the end, it just help me to increase the security and comfort of my trips. It reduce the risk. Today, my wife has multiple health problems and do not have the strength to fight, even inside the boat, against difficult conditions (the last one was 52 knots during 24 H). So, I appreciate all those technologies to avoid to put her in real difficulties. Today, I can avoid them with more accuracy and I appreciate. Without those technologies, I’m afraid the alternative would be, today or tomorrow, to stay on earth.
Fair winds to you.

Re: polar diagram
Dave_Benjamin
Jacques,
I understand the goals and have made use of software for identical reasons. I just feel that we're better off using some real world data from our own boat or even informed estimates. I can deliver a boat that I've never been on and make some reasonable assumptions that prove fairly accurate. Cheers, Dave |

Re: polar diagram
Jacques Paulus <jacquesetannick.paulus@...>
Many thanks for your comments Dave,
The reason why I want to use polars on a cruising boat like an Amel is just the one you mentioned: Security and comfort. When I use a routing software, for which I need to use polars, my objective is to answer those questions: - Am I able to make the crossing I planned without encountering winds higher than 30 knots and without struggling against winds closer than 40° degrees TWA ? If not, do I go or not ? - How many time will it take, given the grib files I received ? - Should I start that day or day +1 ? - What is the best route to avoid difficult conditions ? Those questions are easily answered by a routing software and give you valuable information to help you plan your trip. We are not looking for 100% reliability but for pieces of information to help you to take the best decision as possible. Routing software help you to increase your security and comfort while cruising. Now, it is not ridiculous, on a cruising boat to look if you’re well trimmed and if you cannot do something to increase your velocity. Personally, I started using VMG figures to make choices in order to reach the destination port before the bad weather arrive and this include the decision to start the motor, eventually with the sails. It’s a bit like with cars. Technologies developed for racing can be used by cruisers to increase security and comfort.

Re: polar diagram
Dave_Benjamin
As a sailmaker and former racer turned cruiser, I fully understand the value of a polar diagram. On race boats, we'd consult the polars to insure that with a given sail combination and conditions, that we weren't missing something in the complex equation of sail trim, fairlead position, rig tension, mast butt position, hydraulic gauge readings for the vang and backstay, etc. If we didn't see something obviously wrong and we were off speed, then it was time to check to see if we fouled something on the keel and perhaps were dragging a piece of kelp.
What I'm wondering about is the fascination with polars for a big cruising boat like an Amel. Keep in mind that polars are only valid between closely matched boats. In a closely controlled one design fleet, a set of polars will be valid on multiple boats. But throw in any amount of variation in the form of a different prop, less than perfect condition of the bottom, sails that aren't new or are of a different design, fuel quantity, fresh water quantity, and weight of stores and it's just a theoretical exercise. When I'm in cruising mode, my first priorities are safety and crew comfort. When I'm looking at performance, I'm really focused on Vmg. (Velocity made good). I know that we're not going to be operating at 100% of potential because I have an AP driving, my headsail is designed for a wide range of conditions, unlike a purpose built racing sail, and I don't want to sail with the same intensity as I would racing. If I want to use passage planning software, the right answer for me isn't a set of polars. It's data collected from previous passages. If I stepped on a Super Maramu today, could I assume my performance would be identical to my friends on other SM's? I suppose I could use polars as a starting point if I was on an unfamiliar boat and needed to set up iNavX. But once I had some experience with the boat, I know I'd be making some adjustments for real world conditions. Ergo my question, why the fascination with a set of polars for these boats? |

Just for your information:
I have an application on my ipad called ipolar, so I had created based on
the SM polar and PITU (my SM) a polar for PITU.
I exported this polar in another ipad application called Weather
4Dpro.
I do my routing with the ipad app of Navionics, then by email I export my
route to my email adress.
I open the route file from my email with the weather4Dpro application and
with PITU’s polar I can do my routing.
I can also export my route to my Raymarine plotter... but Raymarine new
lighthouse software doesn’t permit this operation anymore... I am waiting for
the new realease.
Kind regards,

Hello Alan,
We hope you are enjoying Fiji, we certainly did during the
late nineties when we used to spend a lot of time in Viani Bay just east of
you.
In the seventies and early eighties I was crewing on top
class ocean racers and towards the end of that time the yacht designer would
provide a large chart covered in numbers being the design calculated speed for
numerous wind speeds and direction and the instructions were to get it out when
we felt that we getting the best speed possible fpr the wind conditions and
correct the number that had been calculated by computer. The chart was returned
to the designer frequently so that he could correct the theoretical figures.
Presumably this was the predecessor of the polar chart which appears to be much
simpler than those horrible charts but is still in need of correction in exactly
the same way.

Mail sheet gear motor disassembly
Bob <bob.sarff@...>
I have a 1985 Maramu that had the bottom bearing seize up so the foil will not turn. I have been trying for a couple days to get the motor/gearbox apart. Does anyone have any suggestions?
So far I have removed the coupling to the foil, removed the gearbox cover, exposing the inner gear and have been trying to pull the gear and bearing off the front of the mast. Since I have the bad bearing removed from inside the mast I thought it best to take everything apart. The gear has come out so that it is even with the shaft in front of the mast but will not come any further. The next step is to apply heat to see if that help. Has anyone has any luck removing this assembly? Thanks, Bob S/V Chara, hin 173 Currently in Raiatea, French Polynesia |

Re: polar diagram, maxsea
Jacques Paulus <jacquesetannick.paulus@...>
Thanks for all your comments. I understand perfectly that a wrong polars file is useless.
The polars calculated by SailGrib are based on VPP calculations (you will have more infos on their website) but I agree on the fact that the results are much too optimistic. What I understand from their explanation is that the resulting polars gives the maximum speed for a boat with the measures of the concerned boat (LOA,LWL, Sail surface, weight…etc…). Afterwards, you can downgrade them by parameters permitting to take account of the actual performances of your boat, but also of your way of sailing (see explanations on the website of SailGrib). The result will never reflect perfectly the performances of your boat but it can be quite near.
Nevertheless, as it does not exist any polars based on actual performances of “old” boats like my Santorin, the polars of SailGrib are the best solution I found up to now. If you know better solutions please feel free to share with us.
I used their software and polars to plan trips from 100 to 200 Nm. It requested some “fine tuning” through the parameters of the software but I’m satisfied by the results.
Of course, I would be very happy to find polars based on actual performances of the boat. But, up to now, I didn’t found them.
The best thing I could do is analyzing the performances of my boat by noting them during 1 year. Afterwards, I could probably create my own polars. That would be fine but it’s a hard (and long) work.
What I obtain as results from SailGrib and their polars, after corrections via the parameters is the best I can do today.
Sorry for being a bit long and my apologies for my “approximative” English and the errors of interpretation it can generate.
Best regards

Hi All
I am just about finished washing everything aboard SM Indecent -- cushion covers, carpets, window and hatch covers.....if I could get it off the boat it got washed! Our cushion covers are Suedeen (spelling?) and they look wonderful -- they really were not dirty, but I wanted to freshen everything. Has anyone ever used Scotchgard or other water/dirt repelling spray treatment on the interior fabrics and carpet? I have a gallon and a spray bottle, but I wanted to check with all of you experienced Amel owners. In our previous boats, going back 20 years, we have always used UltraLeather so we had not concern about a water/dirt repelling treatment. My compliments to the former owners of Indecent! You can tell when a boat has been well cared for from the beginning and continually after. Fair winds! Stephanie DiBelardino SM353 Indecent Lying behind our home off of the Grand Lucayan Water Way |
