Armorgalv vs. Hot-Dipped

As part of our investigation into anchor chain and its attachments (see PS January 2015 and June 2014 online), we examined new galvanizing processes. Steel products that have clearly undergone an unconventional galvanizing process are making their way into the recreational marine market, but because these methods are proprietary, getting specifics about them is difficult. Industry insiders tell us that the galvanizing process is evolving-but few details are made public.

Sherardizing Alternative

In order to impart corrosion resistance to steel, the items are commonly galvanized, immersed in a bath of molten zinc. Hot-dip galvanizing is well established and accepted, but there are alternate technologies like sherardizing.

A Tale of Two Anchors

We check out the Digger Anchor and Kingston QuickSet in the latest series of anchor tests.

Where Credit Is Due: September 2013

Alpenglow I would like to take this opportunity to express my gratitude to (and recommendation of) the folks at Alpenglow Lights (www.alpenglowlights.com). We have many of their fixtures and have contacted the company on numerous occasions for new sales, upgrades, and technical questions. Without fail, they have exceeded our expectations, from offering to perform upgrades at minimal cost, to telling us secret workarounds that enabled us to use locally sourced parts and supplies to re-invigorate their excellent lighting units.

Anchor Tests 2003: Soft Sand Over Hard Sand

In tough testing conditions, and considered by weight, the aluminum Fortress and galvanized West Marine Performance2 do well, along with the Spade Model 80 and the Bulwagga.

Mailport: June 2013

How thick is too thick for the buildup of old layers of bottom paint? This question arises because I have just finished painting the bottom of my boat. Even though I diligently sought out potential flaking spots with my knife, while rolling on the paint (Pettit Ultima Eco), I would frequently get a mess caused by the paint flaking off. I have only owned this boat for three years, so I really do not know how many layers there are.

Anchoring Rights Revisited

I don't know David Dumas, the owner of a lovely Kadey Krogen trawler named Kinship, but I like his style. Fighting against draconian anchoring restrictions on Marco Island, Fla., Dumas recently had his day in court, and the world is a saner place because of it. Dumas, his pro bono lawyer Donald Day, and local boating activists deserve credit for their perseverance. Thanks is also due to the National Marine Manufacturing Association (www.nmma.org), the Seven Seas Cruising Association (www.ssca.org), and members of BoatU.S. (www.boatus.org) whose lobbying efforts last year resulted in a new Florida law that clarifies anchoring rights in the state. Dumas anchored his boat in Marco Islands Smokehouse Bay last January with the intention of toppling a Marco Island ordinance that restricted boats from anchoring within 300 feet of a seawall for more than 12 hours. Similar ordinances, with equally shaky legal footing, are in place in many communities across the nation.

Anchor Reset Tests

When direction is reversed 140°, a third of the anchors never broke out, another third reset at some length, and two never reset.

Does G70 Have Risk of Hydrogen Embrittlement?

Mention galvanized G70 chain in any discussion, and one of the first comments will be a question of the risks of hydrogen embrittlement. Though hydrogen embrittlement is very real, there have been no well-publicized cases of galvanized G70 anchor chain failure, nor cases of hydrogen embrittlement in new galvanized G70 anchor chain, and negative comment is apocryphal, in our opinion. Scare mongering at its best, or worst.

Plug that Chain-pipe

I was always amazed at how much water could seep through the chain-pipe and into Toscas anchor locker when a sea was up, or we were punching into a headsea-although punching would hardly describe the ungainly motion of a gaff-rigged ketch to weather. Wallowing? Submarining? Regardless, the chain-pipe was like a water main in those conditions …
