5 year hull osmosis warrenty plus more (can get details) and 2 years on most all components. One point of contact for warranty claims, as in no dealership runaround on getting things fixed. You get your own man that is Jeanneau factory checked out to sub-contract or do repairs the right way.
The hull is coated with a vinylester resin. This is as close to a full barrier coat as you can get other than straight
epoxy, which raises costs for you.
Epoxy is best so far, unless their is something even more expensive out there. Vinylester resin was the big thing in the late 80''s and still the most commmon today and practical yet proven effective. I will give you an example of it''s barrier effectiveness as far as fighting against blistering.
I just sold my 1987 Frers 36 which had a vinylester resin barrier, I feel the boat was only "average" taken care of thoughout it''s owners and it never had a blister till I sold it. A vinylester coat will take care of you for as long as you own the boat, so no need pay for anything more expensive. You still have to upkeep the hull regulary, as with any boat (cruisers about every 16 months, pending location and
paint quality and worth the money for good speed) I hope that answers your question about warranty. Also many manufacturers will take care of you a year or so after warranties expire.
How does a new boat help you...Think of all the little things you have to buy for a used boat, then think of all the sweat equity you have to put into installing them. Then think of all the time you catch heck for tinkering with your boat down at the marina for those long hours. Now think of a boat where you do some preventative maintenence, wash it and go home early each night after sailing. These are the things I went through and finally after owning two large used keel boats I am going "new" I just enjoy my sailing too much to be tinkering for long hours. I like to tinker but not till 1am some nights. Any boat new or used will always give you some tinkering opportunities each day. Let me know if you want to hear more, I was dead against new boats for a long time.
