and there heights ! Any one know of such a site ?
st nick,
As I said in my first post. Go to ActiveCaptain (
https://activecaptain.com/index.php ) and use the Interactive cruising guide" to see all the data you need. Just zoom in on your course to see the info. The red blocks are marinas, the green ones are anchorages, the blue ones are "local knowledge" and the yellow ones are hazards. If you are only interested in the bridges, they are the blue ones. You can check mark the other ones and only see blue.
Also, as I said, they have an app you can download to see the same data when no Internet connection is available.
Standard disclaimer, I am not connected with them, other than a user.
By the way, to see how we use it underway, you might want to see our short Youtube video we did on our coastal Navigation at ;
