Practical Sailor unofficially recommend Schaefer
I have Schaefer on my Catalina 36 and I like it. It works well and it is relatively easy to get at the turnbuckle for rig adjustments.The review that PS made of Headsail furlers in August 2004 was a review of what "the best riggers in the business have to say about the systems they install, maintain and repair." They had not each installed and maintained all of them so there was no clear winner. However, I will quote you the final paragraph of the review:"So who comes out on top? Our unofficial winner in this highly subjective survey is the one product that none of these riggers faulted; one that was invariably used as a standard forexcellence: "I'm not sure I want this in print," said an unnamed rigger who was referred to us by another manufaturer's distributor, "but I highly recommend Schaefer. They're relliable. I like the bearings, they require very little maintenance, they are robust, the installation is easy, and they are quite conducive to disassembly." Harken's furlers garnered high praise, though they seemed to be more complicated to install and disassemble, and Furlex and Profurl both won emphatic support among many of our riggers. All told, the bar has been pushed to an extremely high level by these four product lines, and collectively they represent solid investments."A wise thing to do might be to go PS at http://www.practical-sailor.com/backissues/sailsrigging.html and purchase the article which has a more background and includes information about quite a number of different makes.
