This small tutorial will show you how to create charts for Garmin Marine GPS chartplotters using the output files created by Reefmaster.
It uses GPSMapedit and Cgpsmapper (free version). You'll find life easier using the GPSMapedit skinfile here, as it will give you a more or less faithful rendering of the finished chart.
The screenshot to the left was created using only Reefmaster output, and was taken from a Garmin GPSMap 551s
Garmin RM 1
From the Project tab right click in the map, save your map using "Write to file" - "shapefile". You can also right click on a user map name in the "Maps" tab and "write to file". This will create a group of shapefiles in the chosen directory.

Now from the "from list" tab select the 0x0101 Land type......
Click through the labels dialogue - you don't want labels, and select all levels......
