I do not trailer the Extra Credit much. I use the boat for coastal cruising around Newport Beach so I finally installed a furler. In consulation with local riggers I decided on a Schaefer Snapfurl CF500. Ullman Sails made the head sail a few years back and did the modification as well. The sailmaker thought the dark blue Sunbrella materiel to protect the sail would be to heavy so he stitched lighter sheath for it.
