Raymarine Hunter 33 Owners’ Notes page 18

Knotmeter
You have two speed sources: speed through the water (shown as the speed value in
knots on the i70 instrument) and speed over ground (shown as the SOG value on the
p70 autopilot instrument, which uses GPS data and takes current into account).
The speed through water and SOG should be closely calibrated and can reveal important
information. For example, when motoring or sailing into the current, the speed through
water might read 6 kts and the COG might read 4 kts, meaning you are being slowed by
2 kts of current.
VHF radio
• ICOM IC-M422 VHF radio at the nav station.
• Always monitor Ch 16. As the nearest vessel to an emergency, you may well be
able to save a life or a boat.
• When contacting marinas or nearby boats, set the VHF to low power.
• Also included is a portable VHF for use in the cockpit. It has lower power and
should be on and in the cockpit when you are underway. The portable VHF and
its charger are kept in the navigation station.
For your convenience, we have "tagged" two channels for you: 80 (San Juan Sailing)
and 16 (the emergency and contact channel). The VHF is not connected to the
network.
The "WX/CH" button accesses the weather channels (channel #4 is most often in
range). We listen for "Northern Inland Waters." Pressing "WX/CH" again returns the
last used channel. To adjust volume, hold "vol" for a few moments then release. The
up and down arrows now adjust the volume rather than the channel.
Emergency Procedures: please see #1 in the above Owners Notes.
