A new version is on it's way, and it has some great new features.
A new "Trim" button in the Statistics View, let's you trim/uptimize your polars.
In the sample below only a few values have been typed in for the one side of the polar. A tap on the Trim button an values have been mirrored and interpolated - also interpolated across windspeeds. This will make it a lot easier to get a valid polar.
It's now possible to save temporare waypoints
A new setting to let iRegatta determin your best tack and jibe angle from your polar. So if you have a valid polar you don't need to type in these values, and they'll even be windspeed dependent.
A new "steering bar" in the race view, will help you steer the right up- and downwind course for optimal VMG - based on polar or typed in values for tack and jibe angle.
A new burn or gain bar in the start view, will visualize if you need to burn or gain some time to hit the line at the gun.
Look out for version2.85!
