Did your GPS show you any yachts, ferries or barges that might be an issue?

Alright, let's start ripping you down. Do you actually sail? Do ferries and
barges just wander all over the LIS? No, they operate in lanes that can easily
be avoided with GPS. As for yachts, you have horn/bells
It's clear you know little about sailing. The #1 reason for radar on the LIS is
for tracking thunderstorms. Try asking a few people who use it and see. Even
the fishing boats on City Isle. use it primarily for that.
Sorry, you've made a jerk out of yourself....or you were one all along. You
actually sound a lot like Binary Jane!
