I believe these devices are not legal for racing, there is no technical difference between this device and a "water jacket". i.e. you can wear a real big water bag on your back for first upwind leg, then dump out all water at first mark, and cover your opponents. Highly unfair, and ruled out. I believe there is actually a IYRU or USYRU (now US Sailing) appeals case.)

It really p*ss*ed me off, because I have had one salivary gland removed due to tumor, and I get really thirsty when sailing. And, with my unirig, there is no wench onboard to hand me a drink, either!! Wonder if I can get a doctor's note?
