I have an O'Day 26 and I need to replace my headsail furling system. I am considering the Harken Mark III Unit 00, which uses a flexable plastic foil for trailering. I use a 150 Genoa and I would like to know if this unit would handle a large headsail. Does the reefing feature work satisfactoily and is the drum large eneough for easy operation? Any information would be appreciated. <wave@rockisland.com> Thanks, Herb
