I am looking to replace the 3 blace fixed props on my 46' cat with feathering or folding props. From studying forums
and manufacturer's websites I gather that no matter which prop I choose i will likely gain at least 1 knot
under sail. The most likely candidates are the Kiwi-prop, Autostream, Gori and Autoprop. Autoprop sound great but they are very pricey, especially when you need 2. Gori is appealing because they present less radius when folded, which in the case of a cat with daggerboards and no protection for the props could be a good thing. They also claim an "overdrive" function usable in calm water
. However, this sounds suspiciously like advertising hyperbole. Kiwi-props are lightweight, less expensive and theoretically repairable if damage occurs to a blade. Autostreams look bombproof. Does anybody have any experience with these? Thanks!
