Realtime account from the busy boat -crowded Ches Bay : Years ago my little brother was crewing a sailboat with a more experienced captain. In a crossing approach with another sailboat on port tack, brother on starboard tack, the give-way boat did not adjust course to avoid a projected collision. Captain called for a steady course as the CPA closed. My brother noted that the crew was not on deck. As the captain blew a signal my brother sailed their boat into a collision. A large hole was driven into the boat at the hull-deck joint by the give-way sailboat. Their sailing week was over. Upon arrival back at port statements were taken by the authorities. The determination was made that there was equal liability between the parties to the collision. The give-way vessel was in violation of Navigation Rule 5 and 16; and the stand-on vessel was in violation of Navigation Rule 17b. Captain of my brothers boat idenfied a imminent collision and when all actions to alert and secure safe crossing did not take action to avoid a collision. He was the last party to the incident who could have avoided the collision. This example is offered to illustrate that avoiding collision is the point of the Rules, not establishing right of way liability for the purpose of litigation. Repair costs to my brother's boat were equally divided with the owner of the give-way vessel. The captain requested that his insurer contest the opposing insurer, an attorney for his insurer sent him a negative with the admonistion that he better acquaint himself with the Navigation Rules.
