For all scrubbers

and btm sanders. What about my idea: instead of pushing up from below, get a long pole with lawnmower style handle, fit sanding/scrubbing pad looking up (swivel type) suspend middle of pole from halyard with a good length of shock cord, adjust for upward pressure, so you push down as you reciprocate.?? Hull polishing, just hang the machine on it.

I like the idea but I think that the shock cord is a mistake. When pressing down to apply pressure I think that it would be hard to control the pressure. Also, I normally rinse the pad regularly in a bucket and I think that the tether might prove more trouble than it is worth. In addition, I might have to steel myself against other boat-owners laughing at me as they pass by. I look forward to hearing how you get on.

That's a clever idea that could work for me - I run the boat onto the beach with a rising tide and go round with a long handled scrubbing brush. Takes about an hour, but it's hard work, though. Brushing under water means you don't need to withdraw the brush to rinse it off. I think it would be better without the shock cord so that you could press down on the handle for the hard bits. I don't worry about what others think - I just remember the £100 plus I'm not paying for a lift and scrub, or the whole day spent waiting for the tide at the scrubbing piles.

I'm well familiar with what you're doing here. It's called procrastination. Now get sanding! Soon your shoulders and arms will grow to the required size automatically.

I thought this was going to be about Southampton or Portsmouth, either a steer to or avoid experienced users guide...

If you want some upward force applied to the pad/brush without tethering it with a bungee or whatever, simply tie a small fender or other buoyant item/material under the business end of your gadget.

 

[fisherman]

using shock cord, if you have one long piece you get minimum pressure and long range, but multiple short lengths can provide higher pressure with much less movement.
Yes, I thought about using buoyancy as the next step if afloat or drying. I started out trying to invent the marine equivalent of a car wash, drive the boat through a set of underwater brushes.

 

[neil_s]

The problem with buoyancy on your brush is that water resistance makes it hard to push back and forth. An economy size electric toothbrush is what we need!

Are you by any chance being paid by the hour ?

Every time I have consider scrubbing with a pole I have found it 5 times easier either from a dinghy tied to the rail (top sides or waterline) or in the water (anything below water). Not just faster--physically easier.

It's simply pointless to ponder this. You're making the pros laugh. Get wet.

I plan to make my first million marketing a hull cleaner that is an inverted, heavy duty (and subtly buoyant) version of the old manual carpet sweepers (remember them!).

I think Ew can bank on making a fortune from that.
