Sailing videos have been around for years, of course, and two of this month's authors are old hands at the form. Don Street was ahead of his time in 1985 when a 40-year-old British ad exec named Gavin Shaw signed aboard Street's 46-foot yawl, Iolaire, to sail and film a three-month, 5,000-mile transatlantic trip from Ireland to Antigua. Rereleased on DVD, the two-hour documentary encompasses the rhythms and frustrations of ocean passagemaking, punctuated by scenic port visits and crew changes, some planned and some not. Along the way, Street dollops out his accumulated sea sense, navigational pointers, and a steady diet of one-liners. Although the film is 23 years old and sometimes shows it, the lessons are timeless and the trip enjoyable.
