During the months of August & September, I am keeping my trailer-sailer, a Venture of Newport 23, in a slip at Glen Cove Marina on the Carquinez Strait just east of the I-80 bridges, for purposes of getting more sailing time in during the waning days of summer. In preparation for a sail on Friday with Mark Potter, a cardiologist from my church, and his daughter Kat, a first-time sailor who is soon bound for college at Point Loma Nazarene University near San Diego, I went to the boat on Thursday afternoon for a couple of hours of last-minute preparations. With my new Wind Wizard, I recorded temperatures of 91 on deck and 98 in the cabin, with no wind gusts above 8 knots. Since the forecast for Friday was similar, I wasn't expecting great sailing conditions.
