Propeller test on good old "RIB"

[bogib]

Went out today on the old Humber SAR powered by two 70 Yammies testing new stainless steel props as they damaged their old ones on recent rescue mission as I was not happy with the results they came up with and wanted further tests and results was according to my expectation speed 32 knoths with 3 on board and only lost 1 knoth with 7 on board and only 300 reves from max so they decide to keep those props
