rigid job absolutely required with in-boom furling.
The fittings on the cockpit coaming look to me like Bimini anchors.
I suspect the mainsheet goes to a backward tackle and a hydraulic ram inside the boom. I delivered a Wauquiez 60 (way back) with that system. Looking thru the boat on arrival, I wondered what the big 6-part tackle in the lazarette was for. Found out when we lost the hydraulics.

Maybe for Ron's sake (above) they have a very tall boathouse to put her in . . .
