Default Faulty depth finder attributed to whale attack!!

Jon has a point. There are certain locations that are notoriously poorly charted,
datum-wise. The ChartKit I have for the Bahamas is way off. I also found that for long
stretches of the ICW, my charted position was on dry land.

For most of where I sail, however, the GPS and the chart agree to a boat length or better.

Were did you dig up this crap Jon??? Learn how to enter correct datum and
save yourself further embarrassment.

It's a good thing both you and Neal sail in protected waters with line of
sight navigation or there would be a lot less boats around.

| Good Morning Simple,

| Many of us SAILORS that sail among Whales use charts and depth finders

Nice
