A neighbor-renter brought his Farrier trimaran—
below.
I'd posted earlier of a "
ride" in one. My "ride" achieved 17-knots with 13 aboard—an International crew, counting at least three languages—I was getting beat-up and soaked, 'cuz the rest of the crew were in the galley, getting lunch! How beat-up, you ask? Though a brand-new Farrier-29, heavy water-action still managed to drive my right knee right through the trampoline!
With his Winter Harbor McMansion-rental running ~$5000/week, he surely was disappointed that winds were gentle during his stay. But at least he didn't have to motor around—and miss all the
natural attributes that Lake Winnipesaukee has to offer.
