All I want is a program to run while racing around the bouys and
cruising on weekends that computes and displays real time upwind and
downwind laylines.

I have a hot new PC laptop that I'll use on board, integrated GPS,
full ComNav NX2 instrument system.

I'm trying to decide on what software to buy.

Will Nobeltec do this? RayMarine will but that's more expensive.
MaxSea will if you buy the really expensive version (not the 5K
version)!

HELP!

Bill
