Someone at Muiderzand has an (uni)F17 (with the Infusion stick) which he IIRC had weighed at 135KGs.
He does have PBO rigging and a carbon pole so that might make it a bit lighter than the standard version.

Macca: Do you know under which rating they where sailing? I cant find it anywhere and I dont think F17 rig has been added to the TR database.
