Hello All,
As a former professional mariner who was taught old school--I don't need no stink'n GPS to fix a position. For any trip under 100 nautical miles to sea, all I need is to catch an occasional glimpse of the binnacle to know where we are going. I always study charts, Coast Pilots, and other navigational information before a voyage. If the skipper does not make me sign a waiver in advance regarding the positions that we dive, I will plot those dive spots on my charts once I get back home (or while I am on the voyage). Currents, wind, fetch cycle anomalies, low visibility, impending hurricane--it does not matter as I can work through the navigational problem.
As a currently licensed master mariner who has Merchant Marine Academy training and experience as a merchant seaman on small and large vessels, it is legally incumbent on me to keep track of the actions of the vessel's crew, even though I am a paying passenger. I wish this was not the case; however, Administrative Law judges have created precedent where a professional mariner must give assistance and advice to a crew when an accident happens or is about to happen. I can't claim that I was not crew on the boat and wash my hands of the situation. I know better; therefore, I could be held partially responsible for any accident that occurs. As a result, I study-up on local knowledge before every dive or fishing trip I take. I also evaluate the condition of the vessel and crew. We have declined trips because the crew and/or boat were not fit for sea and have so stated this information to the operator.
My point is this: The crew can cry all they want about protecting "their" sites. They don't own them. If they want to keep their sites secret they should not sell rides to them!
Captain Mark.
