I'll be doing bluewater sailing and need to replace the furler for my genny and add one for my staysail. I've narrowed it down to Schaefer or ProFurl. I'm leaning Schaefer, but the way they prevent halyard wrap at the top is different. ProFurl has a patented tab that mounts above the top bearing that the halyard bumps into. Schaefer requires a block to lead the halyard down the mast a short way so it reaches forward to the top swivel nearly horizontally. The last thing I want is a halyard wrap when I'm in the sh*t. Any positive or negative experience with either system? Thx!
