Hullmate.

3 of us on the east coast clubbed together to share one.We are all pleased with the results.2 have Coppercoat and use the harder sponge and I use the softer one as I have traditional eroding antifoul.We all have fin keelers and with the long handle can clean the fin keel.You need to have the wind blowing off your berth to give you space to get the handle right down the side.The sponge has lasted well and has at least another year left in it.
 
Point 1. Of very limited use for bilge keelers.

Point 2. Looks as if a pontoon is needed to use it. So again limited use for those on swinging and fore & aft moorings.

Point 3. Very expensive for such an apparently simple and easy to make devise so a rip-off IMHO.

Point 4. God gave us tides so that boats can be beached for a scrub off at very little/no cost.
 
It works.

Haven't figured how to link to a previous thread, but it is all here. Using the search option in the header bar, enter 'Hullmate/Brizo hull cleaning system review'..
