Why Buy From Fondriest?


Benefiting from years of Fortress Anchor research and development, the Guardian anchors offer excellent quality, performance, and economy. Made from the same high tensile, corrosion resistant aluminum magnesium alloy as the Marine Anchors, the Guardian anchors provide years of service at an affordable cost.


Guardian anchors are available in five sizes, capable of anchoring boats between 12 and 41 feet. Built with slightly smaller extrusion profiles and minimal added features, the Guardian anchors are an affordable alternative to the Marine Anchors. 


All Guardian Anchors feature Mud Palms designed to help the anchor set faster in any type of sea bottom. Mud Palms are a set of plates that bolt on the crown of the anchor. They create a lift to the crown of the anchor, causing the flukes to point more directly to the seabed, helping set the anchor faster in any sea bottom.

US Steel Dumping Chromium: Citizens Fighting for Lake Michigan, and Drinkable Water

If you remember the movie “Erin Brockovich,†you are already familiar with hexavalent chromium, a toxic substance that was contaminating the drinking water of people in California in the movie ( and in real life ). Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.

BOB and MARI Will Monitor Water Chemistry in the San Francisco Bay

Scientists have had nagging questions about how ocean acidification might be affecting the waters of the San Francisco Bay. But if you can't trust BOB and MARI with your research questions, who can you trust? That's BOB, the Bay Ocean Buoy and MARI, BOB's companion mooring for Marine Acidification Research Inquiry, of course. BOB and MARI are a bright yellow, five-foot tall buoy and its companion mooring, respectively. They are anchored near the Estuary and Ocean Science (EOS) Center of San Francisco State University (SFSU). SFSU researchers are collaborating with scientists from the University of California, Davis and other funders and partner organizations on the first long-term project to monitor carbon dioxide and ocean acidity in the San Francisco Bay.
