Anyone who has been involved with marine sports over a long period of time has undoubtedly, more than once, been affected by sudden changes in weather that resulted in a completely unexpected, and frightening experience.

In order to increase safety and the "peace of mind" aspects of marine sports, I would like to introduce applications of pinpoint ocean forecasting, with the ambition that it leads to advancement, no matter how small, in the development of healthy marine sports.
