  • Pennsylvania
    Spring 1991 $1.50 Pennsylvania • The Keystone States Official Boating Magazine Viewpoint Recently we received a letter suggesting that we were being contradictory in Boat Pennsylvania. According to one reader, we suggested that boaters wear personal flota- tion devices, but that the magazine photographs don't always show their use. Obtaining photographs for a magazine can be a difficult proposition. Sometimes we stage situations and take the photographs ourselves. More often, we rely on photographs submitted by contributors. Photos that depict the general boating public often do not show people wearing PFDs simply because the incidence of wearing them is so low. If we were to say that we would only use photos that showed boaters wearing PFDs, we would have a difficult time fmding acceptable photos. Generally, we try to show people wearing PFDs in small boats in situations in which devices should obviously be worn. On large boats, people most often do not wear their PFDs. Should people wear PFDs? Statistics show that wearing a PFD can save your life. Are PFDs needed all the time? Because accidents happen when they are least expected, wearing a PFD all the time is a good idea. Practically, however, as comfortable as the newest PFDs are, they can be excruciating on a hot July day. Many boaters also want to get a little sun. We accept this and our statistics show that the chances of having an accident where a PFD would have been a factor are much lower in the summer months. Ofcourse, circumstances do exist in which wearing a PFD,even on the hottest day, is warranted.

  • Boat Hull Hydrodynamics
    Part I Boat Hull Hydrodynamics Introduction and Background Planing craft, particularly in the extensive worldwide boating industry, are the vastly dominant water craft type. “Planing” of a water craft occurs on accelerating to a sufficiently high speed. When such speed is initiated from rest in calm water, the hull bow angle is forced to increase upward, thereby increasing the angle of incidence of the boat bottom relative to the water surface. This incidence angle, interacting with the increasing boat speed, produces increased dynamic pressure on the boat bottom, which lifts the boat progressively further upward in elevation toward the level of the water surface. There is normally some overshoot: on reaching the level of the surface. The trim angle then decreases back toward equilibrium, with perhaps some oscillation, as the boat settles-in to steady planing on the calm water surface. Decisions required in the rational design of planing craft, particularly with regard to two aspects, are particularly difficult to conclude with precision: these aspects are planing speed and seaway motions (slamming). High speed and low seaway dynamics are the primary attributes sought in any new planing craft design undertaking, but they are conflicting. The characteristic most needed for low resistance, and consequently, high speed, is the weight located aft toward the stern of the boat. But weight aft tends to result in high impact acceleration when traversing waves. Further, weight aft can lead to “porpoising” instability, which is an oscillatory pitch motion in calm water accompanied by slamming oscillation. Conversely, weight forward results in reduced bow impact acceleration in waves, but also gives a long waterline, imposing higher resistance, and therefore reduced speed.

I failed to properly anticipate the effect the current would have on us. I knew that with a strong ebb tide we would have a current setting us to port. Since we were going starboard side to, I planned to make a close approach to compensate for the cur­ rent. What l didn't anticipate was that as we entered the slip the cur­ rent would no longer work on the bow but would continue to push our stern to port. That rotated our bow to starboard and brought us in closer to the pier than I intended. If it hadn't been for the tug we had made up on the port bow, we could have been in real trouble.

  • THE JAVA. [6 Ben
    YesWeScan: The FEDERAL CASES Case No. 7,232. THE JAVA. [6 Ben. 245; 6 Alb. Law J. 421.]1 District Court, S. D. New York. Nov., 1872.2 COLLISION AT SEA—STEAMER AND BARQUE—SPEED—LIGHTS—LOOKOUT—EVIDENCE. 1. On the night of August 25th, 1871, the Norwegian barque Anitas was sunk by a collision with the steamer Java, at sea. Of the twelve persons on board of her, only one was saved, and he was below, and did not come on deck till after the collision. The steamer was going at the rate of ten knots an hour, and the night was dark, with a drizzling rain. The weight of the evidence for the claimant, however, was, that the hull of a vessel could be seen a quarter of a mile. The lookout on the steamer saw a white light about a point on her starboard bow, which, he said, disappeared, and he then saw a good red light. The engine of the steamer was stopped and reversed, but she struck the barque stem on, on her port side, a square blow: Held, that, if the night was a thick night with a drizzling rain, the speed of the steamer was too great; and if, on the other hand, the hull of a vessel could have been seen a quarter of a mile, and the steamer could be stopped in less than a quarter of a mile, then the steamer failed to see the barque as soon as she ought to have been seen.
