And when the seas do rise up, this yacht is ready for the rough stuff. On test day, I powered the boat through Sydney Harbour, past the majestic headlands and out into open water. There, the Pacific Ocean tossed 6- to 7-foot rollers our way. The 39 was ready for them. Her hand-laid hull was solid as we crested the swells, and it landed softly in the deep troughs. I cruised her at 15 knots into the head sea, and took her back in at 22 knots in the following sea with no hint of surfing down the faces. The builder says the boat can do 34 knots on the pins, though I didn’t feel comfortable pushing the throttle all the way down in a boat of this size in those conditions — she wasn’t mine, after all.
