my Garman only has room for 25. I wouldn't know which I had set up that way and which I hadn't so I decided to just leave them as stand alone way points. I don't know that it would save me that much time anyway. I'm interfaced with my autopilot and I'm very careful when using that function. The last thing I need is for some fisherman to put a fish trap in the middle of my last years track. It would be the same with a "route." I plug in my my course and entry into the anchorage, go in on scale and follow the entire course making sure that I have picked the proper way points because some of them overlap with other entries into adjacent anchorages. That's where "racks" would come in handy because they would only pick up the correct WP's. I just don't have enough of them to use them that way. If you just sailed the same waters or had a unit that had 200 "routes" then I could see the advantage.
