This is a Kiwi 35. Or, at least it used to be. From the owner: “I started to modify the KIWI 35, the  infamous light flyer with wings from the 80’s. It took 6 years  from original to present performance with new keel, bulb, carbon spars from a Farr 30, new rudder, bow , wings taken off, reinforce hull and many many others list too long…this year we achieved the top of Everest by winning the prestigious Heineken Regatta in St.Maarten, and whole season showed top performance.”
