Clean hull in the water?

[saurav16]

Is there any chemical applicant that you can put on your hull to keep it from turning the redish brown color near the waterline?

not really. that discoloration is usually from water-borne tannins and other such chemicals.

Try wiping it down with Mr. Clean Magic Erasers (unless, as I'm now told, it's highly glossed).

Tidy Bowl toilet cleaner or anything with oxalic acid works.
Note...keep drips off your bottom paint!!

The obvious, preventive remedy is to remove the problem, so a cure is no longer necessary.

There was a time when we too were plagued by those dreaded reddish-brown hull stains. Since we minimized sailing towards the upper Bay, which is closer to Providence, Fall River and other sources of industrial pollution, the stains no longer appear.

yeah if I could I would choose to not sail on the hudson and opt for LI Sound but its a good eight hours from me, so not an option. Guess I will just have to give it a good cleaning or paint the hull navy blue.
