I'm an original ower of an original Minifish II - the AMF ALcort sloop-rigged version of the Minifish, similar to the sloop-rigged Super Sunfish. Bought mine in 1976. it's been semi-retired for the last decade, but I had it out last weekend. As much fun as ever. Still have all the original parts. This rig planes and skips like a windsurfer in a stiff breeze! I also have a 1976 AMF Alcort sales brochure and the original Minifish II rigging instructions. The hull is a standard Minifish except for the name plate and some uncharacteristically cheezy wood-grained applique on the splash coaming. The mast is unstayed, about 18 ft, with about a 6-foot boom. The sail specs out at 60 sq. ft and it has a 4-part mainsheet, a boom vang, outhaul and downhaul. For a point of interest, the brochure has the following prices for their entire line of boats: Sunfish - $752. Minifish - $525. Super Sunfish - $898. Minifish II - $698. Force 5 - $1085. Puffer - $1185. Sunbird - $ 2535. I'd be happy to answer any questions regarding this rig, and whatever I can find in the brochure regarding the other boats.
