I have a three part question related to a 1990 Hunter 30 and furling the Genoa. This is a single line system -- I do not know the model. 1. How can I tell if this Furlex furler is rated for reefing the Genoa (furling in in part way in heavy air)? 2. Are there guidelines for this kind of use? 3. How does the 30G handle with the Genoa partially rolled up? I have attached a photo of the drum.
