Anchor Chain Re-Galvanizing

Our first anchor chains were 200 and 100 ft lengths.  One for each anchor.  The standard length comes in a 200 ft drum.  That chain cost $800 lasted 3 years.  It was replaced in 2009 and ended up completely corroded in 4 months.  Fortunately it was under warranty due to a bad galvanizing process.  Our current 300 ft chain was bought in 2009 in Ft. Lauderdale from Secure Chain and Anchor for $1000.  They were really great and were able to cut the 300 ft piece from a longer 1000 footer.  The price of $3.30/ft was also much better than the chandlery price of $4.50/ft.

We have an anchor on each end of the chain and find it very versatile for using as either one very long run for deep water or splitting the difference while using two anchors for more security in more shallow water.

The chain was getting pretty rusted at the most used end but did seem to have some life left in less used end compared to other boats here in the boatyard.  It would have made it a few more years but would have taken a toll over that time with thinning and corroded steel links.

As luck would have it, the marina office was arranging a galvanizing run to Butterworth, Penang.  There were 3 of us sending our chain and 2 were sending their anchors.  My share of the transport was $.30/ft.  The chain cost $1.50/kilo ($1.00/ft) for double dip.  Sounds like an ice cream cone.

All dressed up and nowhere to go

So for $1.30/ft we are now able to keep our hard to find 300 ft length.  Keep it in better condition from corrosion, and hopefully it will last another 7 years.
