I've done that. Awesome is one word to describe it. Scary is another. That boat is so loaded up at 30-40kts (boat speed) that you can feel it tense and torque throughout its entire structure, and it is obvious it is on edge. Bearing off from windward through the death zone will give you brown pants.
Iíve sailed a lot of overpowered dinghies, and then big slow keelboats, but never what Iíd consider a large overpowered boat. So, forgive my ignorance, but Iíve always wondered how they jibe these monsters in high wind. Heck, Iíll even chicken-jibe (head up, tack, bear off) a Thistle if itís blowing over 20 kts. Thatís 200 sq.ft. of roached main on a 300 lb round chine hull, very tippy, but not exactly life-threatening.
