Funny that bloopers are coming back in IRC. The boat I crew on was protested for flying a blooper in last year's BYC Mac. I don't think it made much of a difference in the race. It gives us about a 1/4 of knot more going dead downwind. I believe we used it twice for about an hour each. I have to say that it's pretty fun to fly and we make a big deal about putting it up. The sail doesn't weigh much and it can be used as a pillow when not up.
The protest was disallowed on a technicality, but I think we would have won it anyway. As long as the blooper is smaller than the largest headsail it is considered a staysail under IRC. It doesn't fall under IRC's description of a spinnaker. The rule is a bit murky when it comes to the blooper. ORR expressly forbids bloopers.
I don't think a traditional blooper would work well behind the large mains on modern boats. The speed surge issue that was mentioned here would also make flying one very difficult.
GO THE BLOOP!!!
