Hi all,

just found this brilliant page. I am a (recent) proud owner of a 1991 Hobie 16. I am sailing in Cadiz bay, South Spain. I would like to ask the pros here, what would you recommend as a "strong" cleaning agent? I have had some oxid/water dropping down from the shrouds, and now I have a red vertical mark on the hull. I have tried with different "smooth" cleaners (soap etc) but I could not get rid of the mark. How about using solvents? What kind of solvents would you recommend? Or might this affect the hulls? Any hints are very appreciated.

Regards, Claus
