Comments From Previous Attendees

  • In a single class, Mark was able to bring the basics of marine weather forecasting into sharp focus for our sea kayaking group. Now well equipped with the seminar’s tools and resources, none of us will ever again believe that a thunderstorm ‘just suddenly appeared’! 
  • Mark knows weather AND is a very skillful and thoughtful teacher.  I’ve been paddling and diving for many years and I learned a lot in this class.
  • Your class was just what we needed for a good start in learning how to assess conditions and risks due weather during both the planning and on-water stages of a paddle. You are a great teacher of the subject.
