Understanding and Mitigating Marine Corrosion

Join ABYC Lead Instructor Mike Bonicker and representatives from CMP as they provide a comprehensive overview of marine corrosion types, their causes, and effective prevention techniques. We will explore key ABYC standards and delve into topics such as grounding, bonding, anode materials, and the galvanic series of metals. Attendees will learn best practices for selecting materials, identifying signs of corrosion, and managing refit scenarios.

Key Topics:

  • What is galvanic corrosion?
  • Signs of overprotection and underprotection
  • How anodes work
  • Cathodic bonding vs. grounding and best practices
  • Anode materials and the galvanic series of metals
  • Selecting the right anode
  • Testing tools for corrosion surveys
  • Performing bonding checks out of the water
  • Conducting simple cathodic protection tests in the water

    We maintain a 36 foot frp power boat that has a ss skeg bar and rudder.  using zinc anodes(brackish water)  cant seem to keep paint on the rudder and skeg bar.   sounds like we should change anode type?

    What method do they recommend to size the sacrificial anodes?

    I notice there's bottom paint touching the through-hull

    "Sorry, misunderstood. The carbon fiber itself is so positive that it needs no protection. Any metals attached to it fall under the protection level for fiberglass hulls."

    What are some examples of the different wiring for aluminum boats vs. fiberglass to eliminate stray current?


    Reply
  • Matt Wienold
    ABYC Standards don't differentiate between hull types. Metal hulls should be connected at one point to both the AC and DC main grounds.

    Can lack of galvanic isolation lead to paint failure / bubbling on aluminum hulls?  Trying to determine root cause of an unusual paint failure on STBD half of a 34ft hull. Paint is coming off in dime sized bubbles. No galvanic isolator/XFMR


    Reply
  • Matt Wienold
    "Not likely. More commonly a failure of the coating application, possible solvent entrapment or possibly cathodic disbondment from overprotection."

    What is your thought on anodes hanging over the side of a boat while in a marina?


    Reply

    It can't hurt. The biggest hurdle is good connection to ground system.

    Classification by hull material does not address carbon fiber hulls.  Please comment.

    What do you recommend on wooden hulls? People say not to add anodes to wooden hulls. What about stainless shafts with brass propellers?

    I have seen boat owners disconnect the green ground wire on their AC plug-in instead of buying an isolator.  What is the danger of doing this if there is a GFCI connection ashore?

    Perhaps ensure  that the AC grounding system is properly installed and there are no unintended connections between AC ground and the boat’s metal parts.

    When utilizing isolation transformer are there opinions connecting in isolation or polarization configuration?


    Reply

    "Some feel that polarization is safer due to maintaining the ground, but there are no inherent issues with polarization."

    Bonding issue:  100mA AC ground current with ONLY AC Ground connected to boat.  No Batteries on and DC negative disconnected.  Only fix was to disconnect bond between AC ground and DC negative. What is correct fix? Reply
