I always thought Lewmar and Spinlock were competitors, but I noticed my old Lewmar clutch has "Spinlock" printed on the side. does anyone know the history behind these two clutches and why a Lewmar clutch would say "Spinlock"?
I don't know the specifics of Spinlock, but Lewmar was known for buying other companies out and putting their name on the same product. They did this with Simpson Lawrence on windlasses.
