"To sum up, I totally agree with the main point of the blog post, which is that those who undertake an oceanic passage must be aware of and prepared for adverse conditions which frequently arise during these passages. From a weather forecasting standpoint, voyagers should utilize information generated by a professional meteorologist to help make decisions, and should have the ability to fully understand what that information means and what the confidence levels are. This information can be obtained from a private meteorological consultant, or from forecasts generated by the meteorologists at NOAA. A very important fact to understand is that widely available GRIB data has had no analysis by a professional meteorologist and it should not be the sole resource used for voyage planning."
Jon, this fellow is professional meteorologist that offers his service regarding paid routing and weather counsel to sailors that want to make passages.
What he says regarding sailors needing to have a boat well prepared and needing a minimum of experience is obvious as it is obvious that if someone can pay the services of a good professional to adjust his passage times for the better schedule it will be highly advantageous. He say also that he provides that service fora a rally.
However I doubt that all sailors will have the budget to resource to a hire a professional router and meteorologist to his own exclusive service and then again a Rally properly organized makes sense in what regards information regarding departure and route options since a rally will hire a professional like the one that wrote that article to provide for all that kind of useful information.
The discussion should not be if a Rally can be useful in what regards safety issues (it is clear that it can provide more safety) but regarding what should be the requirements a rally should have to maximize that safety, that obviously will never be a full one, and do not dispense from the participants a certain level of experience and boat preparation. Maybe that should be one of the requirements too.
