The Florida current models are in a digital computer format, in files that are provided the day prior to the first race of the series. If your boat has the Racevision system, permitting live computer use of the Deckman for Windows (DFW) program during the race, then the best option is our "current server" DLL for DFW, priced at $500. This inputs our current predictions into all of the usual DFW functions.

If you don't have DFW, the best choice is our "Force 2.5" program, which displays our current predictions over electronic charts of the region (included). This can be used to lay out marks and courses, predict times to complete legs and courses, compute current-corrected headings, do boat simulations, show current-corrected laylines, etc. It can tie into a GPS and act as a navigation program when used live, but is often used to study the currents in advance and make screenprints at various times and locations to take along on the boat.

This enhanced version of our basic "Force 2" program costs $350, comes with our "chartmaker" facility (see our website at URL: http://www.goflow.com/offchart.htm), and can also display our wind models. For the long ocean race (the 150 nm race), we will have a wind model available for $150, with a model resolution of 1/3 of a degree and timepoints every three (3) hours (the program interpolates between times and computes from the model between points). Note: the wind model requires Force 2.5, it cannot be called from DFW.

With either program, you need a regional data set containing the current information. For the Miami races, the data for each race is based on analysis of immediately prior satellite information, and there is a charge of $350 per race. Our US tidal-current (annual) models are $200 per region, and our UK model with the Solent and English Channel is $300. Once you have the program (or DLL), you can purchase additional regional coverage when you need it.
