17 foot MFG Sidewinder 1970's vintage? Rescued derelict from a neighbors backyard. Epoxied hull and deck joint back together along port side and repaired centerboard and trunk. Built two hatch covers to replace missing ones. Redesigned the mast step to a pivoting type to ease set up and cut 1 foot off the bottom of the main to raise the boom to more head friendly height. Has a 25 foot mast and full batten main. This boat is very lighty built and with the large rig extremely fast. Mainsail insignia identifies it as a MFG Sidewinder
