I have been boating my entire life mostly inland local waters around Long Island. I have owned several boats as an adult and boat handling is not an issue. I learned navigation old school with paper charts compass dividers parallels stop watch from my Dad an avid predicted log participant. I am no stranger to technology nor afraid of it and I am looking for a refresher in navigation that relies heavily on electronic navigation and a refresh on "rules of the road". I just purchased a Mainship 34 trawler with Ray E80 and will be bringing it back to Long Island this spring and plan cruising in the near future. I had thought of getting a six pack captains certification only for the instruction but I will not use my boat except for pleasure seems unnecessary. Any suggestions for the most comprehensive way to get the knowledge and confidence I desire?
