Looks like your spinnaker & his mainsail came from the same sailmaker ! I`d imagine a GOOD pair of sunglasses are mandatory when choosing that colour for sails.
Great stuff seeing you hold off bigger boats, must annoy them a bit.
Mystere looks like a well-put together little craft,looks bouyant enough for two lightweight sailors as well, probably the closest design to the spirit of F14.
Great looking little boat !
