The interesting thing with this race is there were a lot of JPK1180's competing however they range from the winner Sunrise to boats that haven't even finished yet. They are all over the place. I think it's fair to say Sunrise was very well sailed, perhaps a little lucky and in a boat that rates very well. ...Yes, very interesting.
I think there are two factors playing a role:
1. JPKs perform well under offshore IRC and have been optimized for what is agreed to be a factor here (no bulb, short DWL, rather low SA/D).
2. I suspect a regional factor (Brittany-based) as well as a 'patriot-factor' (many French sailors opting for these boats) which in the end leads to a 'self-fulfilling prophecy' where everyone accepts that JPKs are THE design to have for a succesful IRC overall campaign.
Some things I noted designwise:
The first 'modern' X-Yacht is waaaay down on time, an XP 44, even behind Refanut. I think that is brand-damaging in the long-term and X should prepare a campaign for the next edition to bolster their 'sporty' image, otherwise they end up competing entirely in the luxury market. I'm very impressed with how good the old X332 performed, though.
I also think that it wouldn't have been a good journey for a Dehler 30 OD. I doubt that they would have had fun in the first 48 hours. J/99s did quite well, though.
Not as good as the 3200, however, which on average are at least on par with the newer 3300, maybe even outperforming them on time.
