To find SPEED, place one point of dividers on distance run (in any unit) and the other on minutes run. Without changing divider spread, place
right point on 60 and left point will then indicate speed in units per hour. Example: with 4.0 nautical miles run in 15 minutes, the speed is 16.0 knots.

NOAA VHF-FM WEATHER BROADCASTS
The National Weather Service station listed
below provides continuous marine weather broad-
casts. The range of reception is variable, but for
