I bought a Scrubbis and tried it today. Works at the 80% level.
From the finger pier on a floating dock
I was able to get the starboard side done well, lots of scum floating in the water
. The twin rudders were a bit of an issue, especially as the extensible rod rotates in one direction. Scrubbing the port side from the deck
of the boat
didnít go as well since I could not get the pole far enough out, as one would suspect.
Could not reach the keel
from either side.
I guess it is worth it.
