  1. Green and white corrosion on through hull

    Plumbing, Heads, Water, Bilges etc
    After months of forced isolation very far away from our boat, we came back and found a poor looking through hull for our sink/freezer drain. The boat is an Oceanis 41, 7 years old, and sat at the dock, with a galvanic isolator. Anodes have been changed regularly and bottom cleaned by a diver...

    My description and takeaways for a nasty event. I will humbly accept feedback. This event took place in October, 2019. It was the first day of a 12 week beer can – lake sailing - race season; racing every other Saturday. Typically, we manage to get in three races each race day. During the...

    Diesel
    Hi All, I currently looking at a used Tartan (26yrs old) and have a few hangups, the first BIG one being that propeller shaft is corroded between the engine and the stuffing box and saltwater has given it that bright blue hue.

  7. Yikes! Mooring System Failure

    Gear & Maintenance
    The bad news: Last night, I looked out into our cove to find that our 500 lbs. mooring system was not in its usual location ... in fact, nowhere to be seen. The good news: Our boat is on the hard for the winter. So, this mooring ball was installed with a 500 lbs mushroom in 2009. I found the...

    I have recently un-stepped my mast in order to make a repair. Upon further inspection i have noticed a small area of galvanic corrosion above the cabin, on the forward side of the mast, where a stainless fitting was mounted. The corrosion has eaten a small hole, less than 1/4" in diameter...
