If any of the following is true then seatrack is a compelling solution

I race my sailing yacht inshore most of the time
I do occasional cross channel races
Most of my sailing is around the cans
I do a mixture of inshore and offshore racing
My cruising is usually less than 1000nm
I need simple to use powerful, navigation and tactical software

I find normal size buttons dificult to use at sea

I want to output information to my PDA
