Model Accuracy allows a navigator and crew to instantly understand the strengths and weaknesses of particular GRIB sources (ex: GFS, EC, COAMPS, Predict Wind, ect…) and make a more educated and confident decision on which GRIB source to trust the most. The utility of tracking macro and micro shifts in TWD and watching the shifts inside frontal systems is invaluable in understanding the power of each GRIB source. The ability to have absolute confidence in the primary GRIB which you are routing your boat off of is in fact the best GRIB available is truly intangible. It allows the navigator to spend less time in the nav station and more time resting or on deck. It allows the crew to know the heading and tactics are based off the best information available and nothing was left to just a “gut feeling” or chance.
Inside the graphical plots and results pages the user can identify the “tendencies” of each GRIB (forecasting under/over speed for TWS or TWD left or right of actual captured data). Understanding the EXACT tendencies over a selected time period will allow the navigator to correctly twist TWD and raise/lower TWS inside the optimal routing functions of other sailing software. This way the projected optimal course can always be based on not only the most accurate weather file, but the most accurate weather file that is correctly “calibrated” for the current and past forecast errors.
There are a plethora of GRIB sources, all claiming they are the best source for you and your team to trust as you cross an ocean. Finally there is an application which provides a metric for the consumer, the absolute end user, which ranks the accuracy of different GRIB sources and exposes their successes and shortcomings. This software was made strictly for you, the sailor.
Professional sailing teams spend massive amounts of time and money constantly refining the VPPs (polars) of the boat to ensure the optimal routing software has the most accurate projected performance. Yet every “optimal course” has two variables in the solution, the boat’s VPPs and a weather GRIB. Until now there has been no way to formally analyze the accuracy while on the water of the second 50% of the optimal solution, the GRIB. Without reservation a team is now able to know they are pairing their best VPPs with the best GRIB possible for the optimized route. Every sailing team always wants to know they have the absolute best VPPs loaded into their routing software, now they can know they have the absolute best GRIB as well.
