Had an idle couple of hours today so decided I would update a paper chart or two.
Started with Moreton Bay Aus236 . Bought up web site . OOPS been a few years since I updated . 86 corrections a couple of which were important especially if at night or bad weather. That jogged my memory that a few months ago traversing a new channel channel to me using my GPS for reference a channel marker was not on the gps. I looked up garmin today and updates are available for a fee but how often do they update.
