Re: Garmin ChartPlotter Confusion

Hello,

I am not a garmin expert but it look like both GPSMAP and ECHOMAP support sailing assist.

From the Echomap Plus 73 page
https://buy.garmin.com/en-US/US/p/593003

SailAssist Features
SailAssist features include laylines, enhanced wind rose and heading and course-over-ground lines. See true and apparent wind angle and speed as well as set and drift and a glance. To help you gain a wind-maximizing competitive edge, a pre-race guidance page that shows your virtual starting line along with data fields showing laylines, time to burn before the start and a race timer.

For networking:
Connections
NMEA 2000 compatible
Transducer pin numbers 8
NMEA 0183 input ports
1

NMEA 0183 output ports
1


And from the GPSMAP 722 page
https://buy.garmin.com/en-US/US/p/561650
Built-in SailAssist Features
To help you gain a wind-maximizing competitive edge, your chartplotter features a pre-race guidance page that shows your virtual starting line along with data fields showing laylines, time to burn before the start and a race timer that can be synchronized across all your networked Garmin GPS products. In addition, other supported sailing features include an enhanced wind rose, heading and course-over-ground lines, set and drift, true and apparent wind data and more.

Connections
NMEA 2000 compatible
NMEA 0183 input ports
1 (Differential)

NMEA 0183 output ports
1 (Differential)

The GPSMAP units support RADAR.

That's about all I was able to find in 10 minutes or less.
