Thank you for your replies. You've given me pause and the opportunity for more research. I have spoken with one of our area's premier sail makers, and he is decidedly positive about the unit in terms of sail shape and ease of reefing.
One thing that I have been told is that the boom on both the Schafer and the Leisure Furl must be at a precise angle (87 degrees?) for the main to be raised or lowered. Also, on the Leisure Furl, the furling line must be kept taut when raising or lowering the sail. Some difficulties that have been related here may be due to improper procedures.
I am getting contact information for several owners, and I will ask them questions prompted by your responses. Thank you again.
