That is a good question-and I don't have the answer, but I have had as much problem with water flow with heavy grass or kelp, as getting thru it. I have had a fin keel sail boat stopped dead in their tracks at night when running into a floating bed of kelp in the Catalina Channel.
I have hit some fairly good size branches with the SS props and no damage. No rocks yet...But in dinghy's I have hit rocks with aluminum props, which caused significant damage--one episode destroyed the gear case. (12 1/2' RIB in AK, free standing rock, just under the surface...hit at planing speed.). (I had a kicker on the RIB because we traveled significant distances from the larger boat.).
