ORCV Weather Course

      To be next run in 2018

In 2014 the ORCV prepared an all new weather course designed to inform all types of sailors, racers and cruising sailors alike, how to observe weather conditions and how to find the right forecasting advice from the vast array of modern resources available.  The Bureau of Meteorology has made significant progress with it’s forecasting in recent times and now achieves remarkable accuracy, especially out to 3 days. With easy to use graphics and continual improvements the Bureau is working towards achieving higher degrees of accuracy for up to seven days and this technology has changed the focus of sailors. This new course concentrates on the practical facets of weather applied to sailing.

This course is designed to cover the terminology, conditions and weather forecasting resources that will allow sailors of all persuasions to plan their trip from an afternoon on the Bay through to an trans-ocean passage such as a Melbourne to Vanuatu or Melbourne to Osaka race, and the return delivery passages.

There are no pre-requisites for attending this course, however, as the modules progress, a solid understanding of the topics covered in the previous modules will be required, so as to gain the most knowledge from the content of that module.

Course Outline
