New owner of a 2005 Prestige 46 needs help

[benmoore]

Hello all,

I'm new to the Jeanneau brand (former Sealine owner) and have recently acquired a 2005 Prestige 46. I'm so pleased to have found this forum as I could really do with some help.

The boat is currently in Spain and is being transported back to the UK at the end of August. She will be moored at St Katherine Docks in London but I'm hoping to have a bit of post-survey work done at Gillingham first.

It’s a tricky situation as the boat was a probate sale so I wasn't able to get any kind of handover. I went over to Spain when the sale completed and spent a couple of days trying to get to grips with the boats systems etc, some aspects were familiar but some I'm struggling with. I’m posting then to see if there are any Prestige owners out there that could help me with a few questions I have (actually I won’t lie, quite a lot of questions!!)? If there is anyone around the Medway area that wouldn’t mind popping over to Gillingham when she’s back in the UK that would be even better, needless to say I’d be happy to pay for your time .. in cash or beer tokens 

Thanks everyone,

Ben

Hi Ben,

Start by looking at the Jeanneau website where manuals and specifications for current and past models are available.  They are not perfect, but are quite good and will give you a good start, particularly wiring diagrams and some piping diagrams.

When you get delivery and can poke around on the boat, note makes and models of various components e.g. Battery chargers, pumps etc and look on the component manufacturers websites.  These two sources will get you going.

congratulations on the new boat,

Thanks Rene, Ill certainly do that when she arrives back in the UK. I brought the manuals back with me as it goes but I don't find them that detailed tbh.

For example this pic shows the helm with a "Water pump" button and a button with a tap on it

. The water pump does what it says on the tin and the tap one seems to run the fresh water for the heads. The tap one (I'm pretty sure it's that one) also runs some kind of pump in the midships lazerette which makes a right racket which seems strange, also wondering why there are two.

Also the battery charger in this pic

has a number of channels. Channel 2 seems to be the only one that shows any kind of reading but I'm unsure what the other channels do. Also I cant seem to find another meter like this for AC. Unfortunately none of this is info seems to be in the manual, or at least I cant find it.

I've emailed Jeanneau a couple of times now also but nothing back as yet. As you said I suppose its about poking around the boat and getting to grips with it over time, be great to chat to an owner though.

Cheers,

Ben

Hi Ben,

The instruments in your pictures are not familiar to me.  Generally the water pumps pressurise a small accumulator then switch off until the pressure drops due to a tap turned on, and continue to operate automatically when taps are opened while the switch is on.  

I don't know about the tap symbol.  I suppose there could be two pumps but perhaps one is a pump out or deck wash pump.  They can sound bad if there is a valve shut in the inlet or an empty tank.  It will take a bit of detective work. 

The other picture I suggest, is a current monitor, not a battery charger.  The Cristec battery charger used on many Jeanneau models has provision for charging three independent battery banks, and your monitor seems to have provision for switching to monitor each one in turn.  Likewise two switch positions for two alternator outputs (will read zero unless the respective engines are running,) and a switch position for measuring DC current consumption.  If it is all wired as the titles suggest this last position should show consumption by lights, radios, instruments etc but may not show short very high loads such as start motors or anchor winches.  I would expect this to be very useful for monitoring power use, with the other positions useful for occasional trouble shooting once you are familiar with the normal readings.

We had better hope that other owners join in while you are waiting for delivery.

Thanks for your help so far Rene, it is much appreciated.

Hi All,

Unfortunately I don't have the answer to your question but I hope that you have now sorted the issue? I was hoping that maybe you could answer a question for me?

I'm in the process of buying a Prestige 46 and I'm getting very conflicting information about its fuel consumption. Being an owner of a Prestige 46, in your experience what is the average liters per hour for both engines based on cruising (22 knts) and are there any other speeds that you have found to be more fuel efficient?

Also, I see that she has some pretty large fuel tanks, What range have you seen with your boat?

Thank you in advance

Mark

Just come across your posts regarding the 46.

My own boat is a 36 but there are many common items and systems on these vessels.

The water pump switches that you have mentioned are standard across the prestige range.
The one marked "water pumps" allows power to the bilge pumps, macerator pump and shower pump (which can still be individually switched) whilst the one with the tap icon is purely for domestic use - drinking, washing etc.
I can only think that the reason for this separate circuit is in case a fuse blows with too many pumps working at the same time that there would at least be something to drink.
Whatever the reason it is standard and not due to a fault on your boat.

The electric meter shown is also a standard. The idea is to switch between charging inputs to which is in use.
Channels one and two are for the two engines and channel three for the battery charger. After that it can be a generator - if fitted - or a further unspecified external source.
One peculiar characteristic of this system is that whichever engine is started first will show the greatest rate of charge even when the second engine is started. I have puzzled over this for some time and concluded that the second engine voltage regulator detects an increased voltage from the first engine and decides that the second engine output is not required.
As before this is a standard on these vessels and not a fault on yours.

As a further thought, please note that not only are many of the systems the same across the Prestige range but in many cases the wiring looms are identical. For example, the distance from the lower helm to the rear of the engine instrument panel is about the same regardless of the size of boat. This means you may be able to find
helpful information from the manuals of the 36, 39 or46.
Hope this is useful
