I saw this sweet video made by MtINdo posted on the Sunfish Forum a few days ago – it shows before and after pictures of the restoration work done to fix up a Super Sunfish, and then there is some video footage of sailing the boat with both the Super Sunfish rig and the regular Sunfish rig.
the Super Sunfish was produced from 1974 to 1984 by AMF, the builder of the Sunfish sailboat at that time. the hull of the sailboat was identical to that of a regular Sunfish, but instead of the lateen rig sail used on the regular Sunfish, the Super Sunfish was equipped with a high aspect ratio sail, similar to a Laser sailboat (and it was built to compete with the newer Laser sailboats). the overall area of the Super Sunfish sail (65 square feet) is slightly smaller than the Sunfish lateen rig (75 square feet), so it’s debatable whether there was much of a benefit to switch to the Super Sunfish rig.
here’s a picture of a Super Sunfish rig (that I’ve shamelessly stolen from Proper Course, a fantastic blog about Laser sailing):
compare this to a photo of my regular Sunfish sail setup:
