Note: IMO requires DGPS to the AIS, not a WAAS GPS. We have had yacht
customers (over 60 feet) equipped with WAAS GPS refused transit of the
canal. The AIS reports the type of GPS it is using.

What's also interesting is that the closest DGPS signal to Panama comes
from Puerto Rico and doesn't make it that far...
