As a kayaker, be a defensive driver!
Speed made good.
Compass heads to magnetic, we use magnetic ring on chart.

Chart reading:
Distance, direction, depth, coastal features,
navigational aides, traffic lanes, fathoms or feet.
One degree = Sixty nautical
One minute latidude = one nautical mile
1.15 Mile = One minute = Sixty seconds
Water depth – One fathom = Six Feet
Depth curves – soundings, shoals
Contour lines
Names, places, human made features
Shoreline composition
Lights – FL(2) 30s Rm 21m Horn(2) 60s
Color, Frequency, Height, Noise
TVMDC?
