[ARC5] hazmats?

[Sandy]

Nothing much would surprise me concerning California!  I feel sorry for some of the sensible people who live there!

I painted  a 19’ outboard rig with the copper type antifouling paint and it was rather expensive at the time.  IT is pretty when you put it on, but turns an green hue when it starts to work.  NEVER had any problems with marine growth or :”critters” making their home on the bottom.  The boat was run mostly in brackish water.  Only time in salt water was about 25 miles offshore in clear sea water in the Gulf of Mexico.

I do know people I knew in Florida had a time with bottom growth and barnacles and had to “haul out” frequently to clean the bottom.  Ships that passed thru the Panama Canal sometimes stopped for a couple of days in Gatun Lake which is fresh water to kill the live marine critters attached to the bottom.  They can’t exist in fresh water for long from what I gather.

73,

- and now Oregon is banning copper paint on the bottoms of recreational vessels of under 65 feet. but NOT on larger commercial or naval vessels. How much sense does that make? California is about to do the same thing.

    Several years ago you could use an infinitesmal amount - less than an ounce to a gallon - of a tin derivative in copper bottom paint and it would keep off the barnacles for four- six years. Without it, two years max. So you have to haul out and re-paint twice or three times as often, washing copper off when you repaint. Costs a lot and makes more mess.

    And commercial and navy ships still use the stuff by the tankcar load. (a friend had a Navy buddy liberate him some of the Navy's best some time ago.)
