Beer Can Racing app for iPhone and iPad

Simple Navigation App that lets you plot your course using virtual marks or your clubs Local Race Marks, specify your True Wind Direction (TWD) and calculate the True Wind Angle (TWA) for each leg of the race. Look up your Local Race marks that have been pre-entered for your Region, or you can specify their positions manually. Calculations all include your local Magnetic Variation, so you wont miss your mark!

Beer Can Racing app also includes a TWA Calculator for those times your brain cant do math in 360 degree increments (can you say "off-shore sleep-deprivation"?).

You can also enter race courses using the Bearing and Distance to the next mark, along with TWD to determine your TWA for each leg.
