Blooper looks like this. Faster when it goes up; faster when you take it down. It does stop the death roll of the IOR boats. The photo
is of the Heritage One Ton I raced in the 70s. It was right in a very narrow zone. Once the boat could reach hull speed
dead down or up to 160 degrees, jibing was of no advantage. Head
dead down & use the blooper to stabilize the roll. If the wind
increased, more speed could be realized. We once flew it in 35 apparent and made 12 to 18. The bow was submarining. It was great up to the broach.
Just noticed the date of the previous post - wow.
