I guess FP runs a similar scheme as
Lagoon.
The dealer handbook of Lagoon is available online, just
google for "lagoon litigation distributor book". Very informative reading.
The short version is:
That is the factory is hiding behind the local dealer. In fact the factory is not dealing directly with you in any normal case, they are selling boats to the dealer and the dealer is selling it to you.
Any issue you will have to take to your dealer. He will then talk to Lagoon and get approval for the work (or not). The dealer is then compensated by the factory for the works, possibly not to a full extend.
If you have followed the older Mahe and I think
Lavezzi as well, many if not most of them have developed
Osmosis in a very short time. FP has according to several
internet threads covered all of them under warranty, making them better as new (stripping, drying, complete rebuilding with Epoxy). Even provided extended
hull warranty after the
repair.
So they can't be all just bad.
However I would not overestimate customer service for a boat that has left the warranty period.
Afterall FP and any other builder is just building the fibreglass
hull, the furniture and then adds a thousand pieces of off-the-shelf
hardware.
If you can identify the manufacturer and part number you are better off dealing with the original manufacturer anyway (cheaper, faster, easier).
Sometime to a point where a waterpump ball bearing costs 35 Euro if bought via Lagoon, 15 Euro via
Yanmar dealer and 0,20 Euro via ebay from the original manufacturer SKF.
With regards to FP:
I have contacted FP for parts. If you get the right
email address, you can get answers in a few days. Not fast by modern standards but still OK.
I ordered a few parts, and it took them ages to get the part because of holiday season (obviously French like their holiday so much tat they close factories and shops for several weeks).
The only important part (cylinder for the lock of the sliding door) is completely wrong, I guess they don't have records of what they used back then...

Prices are still OK for
marine stuff, but
shipping & handling fee and "small order" surcharges are not.
