we saw the loops of pipe. Damn scary buzzing along at high rate of speed and see those things. We were close enough to see two sets . Looked more like loops of about 3 inch pipe more than cables. Criminal for companies to leave that stuff. These were west of the rhumb line from the last rounding mark (I believe it was D mark, but I would have to look at the Race instructions again) before clawing back toward the 3/4 south boater cut gate. Really caused pucker factor !
