Which mast uses which system?

The information provided below is for general reference only.

Dimensions of mast luff groove profiles may vary. It is good practice to test the fit of Track Mounting Slugs or Ballslide Feet on the actual mast to verify a correct match. Please double check the type of mast that is fitted to your boat, and check with your nearest Ronstan office or distributor that the system suggested for your mast conforms with the stated mainsail area limitations for that system
