NautiCalc 5 out of 5.0

It does everything I need on the water.I don't know of anything any better. I recommend it to everybody.
Repackage it if necessary and leave it on your main website. I had to go look for it.

Road Rally 5 out of 5.0

As a Rallymaster, I find this a great aid in scoring the results of a TSD Road Rally. Rallies are sometimes scored in seconds and sometimes in hundredths of a minute - this handles both.
