As far as Jeanneau goes.....I'm probably a bit like soon to be gone moderator Bryan and Catalina, Jeanneau builds a fairly decent boat for the $$$$$. IIRC on the ARC around the world cruise, Jeanneau was the most sailed boat. Beneteau right after. But that does make sense since Jeanneau builds more hulls than anyone else, with Beneteau behind them. Most of the Jen's were 45-50 or so feet long. Altho I am recalling with out looking it up, the SO 49 or 54 were the most popular Jeanneau models. Even the ARC has more Jeanneaus the last few yrs than other brands.
A number of folks on the owners forum are cruising what I would call reasonable world wide on the 39 and larger boats, be them std cockpit/cabins, or the what is becoming rather popular, the deck saloon models.
If you want to go older, ie last 5-10 yrs, the SO 37's and larger are doing quite well in offshore situations.
Also Europeans seem to be willing to do more with run of the mill brands than we on N America. Then it could be that they are not as well protected from larger ocean swells, so they go no matter the brand, they know brands like Jeanneau or Beneteau a bit better.
Not sure if Jeanneau has had a CC in its past, most are std cockpit models. If you go to www.jeanneau-owners.com
you can look up under specifications some of the different models. Chantier Naval JEANNEAU : constructeur voilier, bateau de plaisance, bateau à moteur, barque pour croisière, pêche, compétition
then clkick sailboats, then autres models they have brochures, owners manuals, and spec sheets going back many yrs back into the late 60's when they first started building sailboats. They started with power in the late 50's, and have been in busines for over 50 yrs.
The biggest issues with Jeanneau and a CC model. is you could be looking at a boat from the 70's. I would want something a bit newer personally. Then again, what decision is not personal in nature when it comes to something like this.
