You are welcome to transmit a moving position report more often
when underway, so that a lost packet does not have as much of an
impact. At the Naval Academy, we used 10 minutes per boat, but
we had our own frequency. I woiuld think the APRS 10 MHz freq
could handle 30 minutes per boat while underway easily.

I think that would be the APRS "directed Query" that would
trigger the position update. Or does WinAPRS have the ability
to trigger a posit in response to a message too? Just trying to
clarify how that worked.
