Mahe 36: Original FP Mahe 36 Thread

[Cotemar]

Mahe's

Changed the Davit pulley system from the back breaking Factory 3 to1 to an Old age friendly 6 to 1 system.

Here is the process:
1) Drill out the 2 rivets holding the cast pulley system into the davit tube

2) With a hammer and punch, tap out the .552 pin through the pulleys

3) Tap rivet holes out with a 5/16-18 tap for Stainless Steel 5/16-18 bolts 1” long

4) Ordered Grooved Idler Pulley
https://sdp-si.com/eStore/
A 6M 9-04812 $7
Outside Dia. 3"
Face Width 0.438"
Bottom of groove Dia. 2.5"
Bore Size .376" must be drilled out to 9/16 (.562)

5) Put a 3/8 bolt through the pulley and spin a nut on and tighten.
Now put this in a hand drill and spin the pulley and file the groove with a 3/8 rough file.

6) Drill the pulley I.D. out to 9/16 (.562) diameter

7) Trace the aluminum divider onto a piece of .040 thick aluminum, then cut with shears and drill a 9/16 hole in the same location as on the template

8) Put a little Lithum grease on the pulley I.D.’s and put the assembly back together

7) Purchased Lewmar 60 mm Triple Synchro Block $58

Hi all,

I was wondering if you would chime in and let me know whether or not this is a fair price I was quoted on a new Mahe 36 from the factory.

2 Cabin / 2 Head Version with following options:
Nav. package (wind/speed/depth, GPS, VHF radio)
Curtains in cabins
Double helmsman seat with back cushion
Cold-water deck shower
Dock lines & 4 fenders
Bag for halyard storage
Mainsail halyard
CST fully-battened mainsail w/ball-bearing luff cars
Genoa w/anti UV bands & roller-furling system
Lazy jacks
1000W electric anchor windlass
Lazy bag (mainsail cover)
Davits
Bimini (hard-top, w/canvas)
Holding tank
110-volt onboard electrical system, w/50’ shore-power cord
Upgrade to 2 x 30 HP Volvo diesel engines (from 2x20)
Antifouling paint (with epoxy undercoating)


The price for the above is about $266K.

Two questions for all of you.
1. Does this seem like a fair price?
2. Is it missing any options that you see as a must-have?

In addition it seems like it's going to cost another 25K at least to get it delivered to the West Coast (Seattle).

Thanks!

Hi,
I have no idea about US prices but I know that there is always a special offer in autumn where you get a lot of extra's at no or low cost.
Check the feauture list at
http://www.euro-cats.de/fileadmin/pd...E-Eurocats.pdf
of the German dealer. The extra options are included I think. You can compare the option list to the one of Fountaine Pajot. You'll have to brush up your German...

Regarding options: In my opinion:
- I would immediately exchange the engine horsepowers for an autopilot. I have only once required full power of the 2*20 HP's in 7200 miles. To go straight against 40 knots of wind between rocks for a few hundred meters. When motoring long distance I hardly ever go over 2000 RPM. We did 250 engine hours using 300 liters of fuel this year.
- Get 5 or better 6 jammers on the roof instead of the double one standard. 6 are required for: Mainsail halyard and sheet, 2 for standard reefing and one for the 3rd reef in your next mainsail, one for the main sail tensioner in the boom. Best is to get two triple jammers.
- Maybe get the standard bowsprit, without the spi or gennaker. The sail you'll probably buy cheaper yourself.
- The external shower can be economically modified from cold to hot+cold by ordering a Plastimo part plus some plumbing. Winter job, if you like that.
- Second water tank is very difficult to install later. Get it now if you think you'l need it. But fully filled up costs you half a knot, more even when tacking against short waves.
- If you sail nights: ask them to mount the new series 32 LED tricolour+anchor light from Aqua Signal instead of the normal series 40 light masthead light from Aqua Signal. Might be cheaper than installing later, should save money for the standard light. If you don't sail at night but only anchor, it's cheaper to get a LED replacement light for the anchorlight.
- Ask them to mount a standard Windex at the REAR side of the masthead, or do it yourself. It is a doable job.

If I did it again, I would ask the boat without any underwater paint, and put on 3-5 layers of anti-osmosis epoxy and 4-5 layers of coppercoat on it myself. This would save the 10-15 days of work to remove the standard epoxy and self-polishing antifouling.

And I would always save money by having it delivered in La Rochelle, and sailing it across yourself or by a skipper. It is hen advisable to go to La Rochelle yourself to inspect the boat on delivery, or get somebody who knows the ship well.

Hope this helps. Kind regards
Jef

Sorry, I just-re-read your question and I notice delivery to the west coast. That changes things..... That is a long trip.
There would be a lot of wear due to delivery. Even the sails. The lazy bag would be completely worn out. Ours is after 7200 nm.

Jef

You can modifying your used $60 dollar Volvo Penta part # 3809924 Air Filters Into washable reusable air filters for $10 each and then wash them over and over again like new. It’s perfect for us catamaran owners who have two engines and do not want to spend $120 for every air filter change or stock these bulky filters on board for and extended cruise.

Purchase a FRAM WA4309 Washable Air Filter at Wal-Mart for $21 and cut into two pieces

The Document of the whole process is to big to post here (Lots of Pictures), so send me a private e-mail and I can send you a copy.

Here are some pictures to show the basics.

Mark, your contributions are really great. So I feel obliged to contribute also. My contribution concerns power consumption and battery life. I have made an excel file (see attached) which calculates current consumption for sailing and for anchoring, both 24 hours/day. So it is less relevant for those who day-sail and are connected to shore power during evening and night.
The Excel calculates power for our boat as it is now, and after the current-reduction measures that I intend to do this winter.
On the second worksheet are my conclusions and additional information.
The central conclusion is:
Per dollar or euro invested, you "produce" a lot more of current by purchasing energy-saving things than by purchasing solar cells.
Second conclusion is:
Even if you mount a big amount of solar power (340 watts) this is only sufficient for 50 % of power needed for continuous sailing, and 70 % of continuous anchorage, even after my planned power-savings.

Hope this helps.
Kind regards,
Jef

Jef,

Nice work on the spreadsheet.

what are your "current-reduction measures that you intend to do this winter"?

I am waiting for my 10 new LED lights to come in to replace all 10 of the Silver Task light bulbs from Halogen 10 watts (100watt total) to 1 watt LEDs. The 3 LED's in the Saloon have worked out great.

That will make her all LED except for the 4 florescent lights ,one in each head and one in each engine room. I will leave those because we do not use them much.

Was planning on adding 460 watts of solar on the davits, so may have to add another 230 on the Bimini

Jeff and Mark thank you for those great informations. I just replaced my air filter....expensive,I know what to do next time.I like to keep things simple and inexpensive,those are great ideas.Thanks

Mark,
These improvements are the yellow highlighted items on the first worksheet. I have already ordered the tricolour/anchor light and the power-saving solenoid for the autopilot's hydraulic cylinder. I still need to find new LED lights for interior light.
Which ones did you choose for saloon and tasklights? Ordered where? How is the colour of the light? How is the intensity?

Which solar panels have you chosen?
Please note that the charge controller is very important. Some of them actually increase current by decreasing voltage, like a switch mode power supply. But only very few have adjustable charging voltage for calcium batteries, which I consider essential (being an electronics guy).

The fluorescent lights probably have an efficiency comparable to LED lights, so I would never replace these. Also they are on seldom.
Thanks
Jef

Jef,

I plan on using 2 SunPower230 watt Solar Panels on the davits for a 460 total.
The controller is a Blue Sky - Solar Boost 50

I have the spec. sheets for both the panels and controller that I can e-mail you if you would like.

I am having a solid stern rail fabricated right now to mount the panels to instead of the lifelines I now have. This Solid Stern Rail picture came from another Mahe on our blog.

Mark,
Here is the link to the product from Aqua Signal:
aquasignal Produkt Katalog
This is the white one, it's also in black but I think white will stay cooler. But second thought, might discolor.
Here's a link for the product in the US:
AQUA SIGNAL CORPORATION | Series 32 LED Tri-Color Anchor Light - White, 32707-7 | 327077 from the ShipStore.com ™ on-line catalog.
There is also a Youtube video. Search on Google for aqua signal, select "video". It's from Jamestown distributors.

I will not change the mid-mast lights. The bicolor is used when the engine is on and there's enough power. The spotlight is used briefly and mainly when anchoring, and then the engine is running, so enough power.

Thanks for your info. I'll search the web myself for the specs of those items, and I'll get back to you if I have questions.

I will also mount the water heater as you suggested. More work...

I was considering to mount the solar panels on a frame on the end of the davits, with possibility to rotate fore and aft. Did you consider this possibility?
Regards,
Jef

[Cotemar]

Jef,

Had not planned on rotating the solar panels fore or aft. Just trying to duplicate what a friend of mine has on another boat. It's a solid flat mount and he has been through a few squals with no problems. The 460 watts keeps all his electronics, fridge, lights and computers going and he does not plug in or use a generator. He is currently in Bermuda and is headed around the world, so I figure if its good for his journey it will be good for mine.

Thanks for the Series 32 LED Tri-Color Anchor Light - White, 32707-7 info
I will order one for my next trip up the mast. Is it just a straight
replacement to what's up there now or will we have to modify anything?
