I use a software package (ExpertGPS) which overlays my waypoints & routes onto any maps/ charts/ satellite photographs you scan in and calibrate. I then laminate these (for emergency use) together with a prinout of the waypoint co-ordinates. I used to mark routes by hand, but find it much easier to modify a route using uploaded waypoints after a trip and then reprint them.

An interesting side effect of doing this and double checking a route (waypoints read correctly from my chart) then using then GoogleMaps/ Earth showed a couple of nasty over zooming errors that I had introduced - far too close to some rocks for comfort ...
