See Pip's recent video. They've put gates in that they can finish the race at if the conditions dictate the fleet not wanting to close the shore.
That’s a good call, particularly with boats that are too deep to enter most harbours, and many only at HW (though hardly surprising, as the guys who organise the IMOCA events are super professional).
I may be wrong, but these look like taken after the finish, or at least after stopped racing, with the sail reduced to slow down to chat on the foredeck. In racing mode one of the bigger jibs/asymmetric would be set - and would be sheltering in the protected cockpit. Can’t go on deck without crawling when at speed in waves, as taking solid water at 20+ knots.
On the contrary, look at many / most modern cruising yachts and you will see masses of things that are more similar to a 20 year old IMOCA, Class 40 or Mini then to a "traditional" cruiser.
Whilst I'm obviously very happy about this, I think for Clarisse and certain others who currently have low qualification miles, finishing the race is so much more important than pushing. So it may well be that she has more pace than she's demonstrating.
