What type of anodes should I being using.

I cruise in the Chesapeake Bay and want to know if using the regular zinc anodes would be just fine for that type of salt base water.

    Thanks Michael T,  One of my boating friend said to use Magnesium and I was telling him zinc should be used.

    To be safe, I would use the aluminum ones. My boat came from Middle River, MD and that is what was on it. I had to change to magnesium when I put her in fresh water.

    Most of the Chesapeake is brackish.  Check out this salinity map:

    http://www.chesapeakebay.net/maps/map/chesapeake_bay_mean_surface_salinity_spring_1985_2006

    The parts in red (upper Potomac, northern tip of the Bay) are fresh, so most boaters there use magnesium.  The blue parts, right near the ocean, are salt.  The rest of the Bay is brackish to varying degrees, so most boaters use aluminum.  

    If you use magnesium anodes in brackish water, they won't last the entire season.  With zinc in brackish water, they won't provide enough protection, so you increase the risk of corrosion problems.

    Bay, welcome to the forum!  I've used Aluminum in the bay for the last 16 years without any issues.

    Thanks Dream_Inn. This will be my first year owning a cruiser yacht Fiesta Vee 310.  I owned a Cobalt bowrider 21 foot since 2001.  Big different and can't wait until I experience traveling in this yacht.
