Replacing Roller Furling
It''s interesting how we all know about the different bearings used by these manufacturers but no one comments on why they''re different. Profurl puts stainless bearings in a sealed, grease filled race in order to take high loading...which if you think about it, is when you most want the furling unit to work and when you normally hear that units begin to perform poorly or fail altogether. In fact, that''s what initially gave Profurl a huge marekting edge: their units were being used by ocean racers in singlehander events, where failure would have been especially bad news, and held up well. ''Plastic'' (of various chemistries) bearings roll much more smoothly and far easily when looking at gear in a show or on a show boat, but high loading distorts the balls over time.
This doesn''t eliminate any furler from consideration; many probably don''t put high loading on their furlers because they avoid sailing in heavy airs. But it''s important to keep this key distinction in mind when choosing gear, I''d suggest.
