2 images. Yacht race, July 4 1955. (Sleeve reads: SP 11490.) Sports.; Supplementary material reads: "Gershon. Sports desk. Att Ben W. Yacht race. No 1 -- 'Barging the Line.' Baruna (black bull) on left and Nordlys (white hull schooner) use same strategy to get ahead of other yachts in start of Trans-Pacific Yacht Race. They are shown on starboard tack (wind coming from vessel's right) crossing the bows of other yachts which are coming up to the starting line (yellow marker in foreground). This maneuver forces other yachts to stand clear at Baruna and Nordlys have right of way because they are on starboard tack, others being on port track (wind from vessel's left). Note one yacht Sea Queen, fending off from Nordlys. No 2 -- Nordlys coming bow on and just passing starting flag, She was first of yacht to continue on starboard tack and make for east end of Catalina Island because of light wind. Baruna came about and headed for Pt. Fermin on Port Tack as did most of other yachts which at Pt. Fermin changed to starboard tack, headed for west end of Catalina Island and the open sea. No 3 -- Baruna (black hull) ahead of yachts nearing Pt. Fermin. No 4 -- Same".本数据集包含2张图片，主题为1955年7月4日的游艇赛事。（封套标注：SP 11490。体育类。） 补充材料说明：“格尔松（Gershon）体育编辑部，供稿人：本·W·。 游艇赛事。 图1——“抢越起跑线”。左侧的巴鲁纳号（Baruna，昵称黑公牛，黑色船身）与诺德利斯号（Nordlys，白色船身纵帆船）采用相同策略，以期在跨太平洋游艇赛（Trans-Pacific Yacht Race）起航阶段超越其他游艇。画面中两船以右舷抢风航行（starboard tack，风从船舶右侧吹来），正越过即将抵达起跑线的其他游艇的船首，前景处的黄色标记即为起跑线。该机动动作迫使其他游艇为巴鲁纳号与诺德利斯号避让，因两船处于右舷抢风航行状态，享有航行优先权，其余游艇则均为左舷抢风航行（port tack，风从船舶左侧吹来）。可见游艇海后号（Sea Queen）正避让诺德利斯号。 图2——诺德利斯号船首正对镜头驶来，恰好越过起航旗。由于风力较弱，它是首艘保持右舷抢风航行、航向卡特琳娜岛（Catalina Island）东端的游艇。巴鲁纳号随即转舵换舷，以左舷抢风航行航向费尔角（Pt. Fermin），多数其他游艇亦如此操作；抵达费尔角后，这些游艇均转舵改为右舷抢风航行，航向卡特琳娜岛西端与外海。 图3——黑色船身的巴鲁纳号领先于其他即将抵达费尔角的游艇。 图4——与图3内容一致。”
