in on scale and place waypoints along a track line that I have just made while entering a new anchorage. I name them "Chacala 1", "Chacala 2" ect. until I have a good track to follow back out at night. If there is no moon, it's raining and the shit hits the fan and I have to make an exit, having the waypoints overlaid on a known track makes it safer and faster to get out. It also gives me a track for the next time I go into that anchorage that is over known ground. The Garman comes with 5000 waypoints so there's not much chance I'm going to fill it up even using 5 or 10 waypoints an anchorage. Going up and down Baja Calif. and Mexican mainland over the years has let me track much of the coast with waypoints inside and outside the Sacremento Reef, dangerous rocks and points and on and on. That reminds me, I need to back all of this up. You could call these routes or even turn them into routes using the route function on the Garman if you wanted but I just leave them as a string of independent waypoints.
