I raced a uni last year. It was a 1995, and I DID use a chute, but only for distance racing and only in winds under about 15. I feel this was more a function of my experience level (I was scared, so I took it down), the mast (older-style ultra-light aluminum) and the sail (21 sq m/225 sq ft Inter 18 sail) than the boat's ability to carry a chute in more wind. I never did get a snuffer; on the other hand, the open tramp without jibsheets leaves lots of options for your bag and spin sheets. I used a 12' pole and sheeted to the shrouds with turning blocks on the main beam.
Feel free to ask any questions.
