Identifying Your CDI Flexible Furler
Are you unsure about which CDI Flexible Furler model is installed on your boat? Determining the model of your furler can be crucial for maintenance, replacement parts, or upgrading purposes. Luckily, with a few simple measurements, you can easily identify the specific model of your CDI Flexible Furler. Here’s how:
Step 1: Measure Cup Diameter
The first step in identifying your CDI Flexible Furler model is to measure the stainless steel cup at the base of the furler. This cup diameter varies between different models:
- FF1: Cup Diameter – 3.5 inches
- FF2: Cup Diameter – 4 inches
- FF4: Cup Diameter – 5.8 inches
- FF6: Cup Diameter – 5.8 inches
- FF7: Cup Diameter – 6.5 inches
- FF9: Cup Diameter – 6.5 inches
Use a measuring tape to accurately measure the diameter of the stainless steel cup, ensuring you measure across the widest part of the cup.
Step 2: Determine Max Headstay Length
Next, you’ll need to determine the maximum headstay length of your furler. The headstay length is the distance from the center of the headstay pin on the mast to the top of the furler drum. This measurement can be obtained by hoisting a tape measure up the luff of your sail and measuring from where it stops to the tack attachment at the bottom of your furler, then measuring from the tack attachment to the base of the headstay.
Here are the maximum headstay lengths for each CDI Flexible Furler model:
- FF1: Max Headstay Length – 21 feet
- FF2: Max Headstay Length – 29 feet
- FF4: Max Headstay Length – 33 feet
- FF6: Max Headstay Length – 39 feet
- FF7: Max Headstay Length – 47 feet
- FF9: Max Headstay Length – 53 feet
Ensure you measure accurately from the center of the headstay pin to the tack attachment to get the correct headstay length.
Step 3: Compare Measurements
Once you have obtained both measurements – cup diameter and max headstay length – compare them to the specifications provided for each CDI Flexible Furler model. By matching your measurements with the corresponding model attributes, you can confidently determine which CDI Flexible Furler model is installed on your boat.
Identifying your CDI Flexible Furler model is a straightforward process that involves measuring the cup diameter and max headstay length. By following the steps outlined above, you can accurately determine the model of your furler, enabling you to make informed decisions regarding maintenance, repairs, or upgrades.
