For the marker buoy setup, check out this website:

You can also just do a search for "anchor buoy".

For the buoy that goes near the end of the rode, rig a fender with a SS carabiner. Drop the anchor and drift downstream paying out line. When you get close to where you are going to tie off, but 20' prior, tie off the anchor rode temporarily on a bow cleat. Put a loop in the slack part of the rode up close to the cleat:

Now clip the fender into this loop, and release the rode from the cleat. Finally, make your terminal tie-off whatever way you were going to originally, preferably in such a way as to allow a quick getaway. Your two buoys will now mark the location of your anchor as well as the end of your rode.

When you are ready to get back on the anchor, motor up to the downstream buoy (mind the extra 20' of line and the propeller), retrieve the rode, and tie back up. No sweat
