Navigating a range

Mile 185 in the ICW guides indicates a front range and then a back range. What exactly is a range and what precautions are taken when navigating? Thanks.

A range or range markers are 2 markers, could be posts, towers, lighted, etc that you would line up to stay in midchannel, usually in a long, straight section that does not have frequent side channel markers.

The rear or further marker is higher than the front marker so the procedure is to line up in the channel so the rear marker is directly above the front.

Good answer. Just think of a range like a set of gun sights. You change your position to line them up.

Also, don't forget to look over your shoulder for them. Some times you will need to line them up behind you depending on the direction of travel.

There are a number of Ranges on the Chesapeake which make night travel much easier....as long as you look out for the ships.

Doh! I did kind of forget that you can be going away from a range as often as towards it.

And remember that if the range markers are not lined up, always steer towards the lower mark to regain the center of channel.

They're also good for checking your compass.
