Knowing how much anchor rode you have on deck is important in setting your anchor as well as for letting your divers know their distance from the boat.
I mark my rode with the rubberized Star Brite liquid whipping dip. Using green (6 inch) and red (12 inch) bands every 25ft it provides a system to know how much you're feeding out. Starting at 75ft (3 small green bands) and marking every 25ft, I use a longer red band to mark 100ft. It's easy to pick up the system; 125ft=1 Red/1 Green, 175ft=1 Red/3 Green, 200ft=2 Red markings).
Hint: Paint won't hold up to salt water or the chafe from your windlass. The StarBrite Dip It stuff does very well (mine's been on for 3 years)
