Rode Counter URC-001

The Rodster URC 001 is the first Rode/Chain counter on the market that can be used for all types of marine anchor windlasses including drum winches. It measures the length of chain and/or rope that is deployed and recovered from an electric anchor winch. It is suitable for horizontal and vertical windlasses as well as drum type winches with the use of a roller. The principle of operation of a rode counter is to measure the length of rope or chain passing around  a gypsy or over a roller. The circumference of the gypsy or roller is a direct measurement of the rope or chain that passes over it.

Save time, battery power and put out the right amount of rope as conditions demand, even at night!

Why measure the amount of rope deployed?

    • Safe anchoring is the main reason for knowing how much rope is deployed , especially at night! In clam waters with little current, the recommended amount of rope to be deployed is 1.5 to 2 x the depth of water. With rougher conditions this needs to be increased by 3 to 4 times the depth of water.
    • Power drain on battery systems is also another big concern. Winches typically consume large amounts of power so knowing exactly how much rope you are deploying each time will conserve power. You will also find that since it is so much easier to pull up anchor and change fishing spots with an electric winch, you will be lowering and raising the anchor many times during a trip, putting further stress on the battery.


Why has there not been a rode counter for drum winches?

As rope is wound or unwound on a drum winch, the diameter of the spool changes. This change is very unpredictable as the rope is constantly bunching and slipping (it does not wind on evenly or predictably). It is therefore impractical to measure drum rotation and have it translated into a useful and accurate measurement.


The URC 001 is designed to work with a nylon roller that lies between the drum and bow roller.

As rope is wound or unwound on a drum winch, the diameter of the spool changes. This change is very unpredictable as the rope is constantly bunching and slipping (it does not wind on evenly or predictably). It is therefore impractical to measure drum rotation and have it translated into a useful and accurate measurement.As with traditional windlasses a magnet is mounted on the roller and an electronic sensor is simply triggered by the magnet as the rope or chain rolls around/ over it.

The time interval between pulses is calibrated and translated to a unit of measurement. This provides a reliable and useful measurement. Accuracy may be affected by any potential slippage of the rope over the roller when the rope is not under tension, usually when the anchor hits bottom ( with little current). An error message is generated by the counter if slippage is excessive. Reversing slowly to set the anchor will place tension back on rope/roller contact point and correct the issue.
