One of the most dangerous aspects of boating is crossing coastal bars.
If you are just starting out, this video from the Brownies Coastwatch Vault shows you some of the basics of bar crossing, but the best advice is to seek tuition, either from a friend with years of bar crossing experience, or a qualified marine teacher.
Asking about bar crossing tuition at your local VMR is a good starting point if you are not sure where to go.
