Not to take anything away from Fortress and what they are...but don't use the Coasties as a yardstick...I was in their procurement and naval Engineering section long enough to see how/why they end up with "equipment".
Thanks for your input. I don't really have a clear sense of how often our anchors are used aboard which boats. I have made it a point to try and talk with the Coasties when they call in to order replacement parts or a new anchor, and I would venture to say that their 87' patrol boat is the one which uses and abuses their anchors most often.
Awhile back I spoke with a crewmmate from the Gulf area in Texas and he wanted to order a new anchor. I asked why and he said that the Gulf waters were too rough for their patrols, and so they had anchored out for 3 days. When it came time to leave, they could not retrieve the anchor and so they had to cut it loose.
Typically when they call to order replacement parts, it is because they got the anchor stuck (sometimes in rocks), and they had to mangle it to break it free.
A few years ago, Bollinger Shipyards contacted us to ask for help in getting the FX-125 approved aboard the new 154' FRC that they were building for the USCG. Bollinger had built the 110' model many years back with the FX-125 aboard, and when they proposed this anchor for the much larger & heavier FRC, the USCG challenged them.
The USCG had calculated that the anchor aboard the FRC had to provide 13,000+ lbs of holding power, which was the force of 70 knots winds and 3 knots of current, as I recall. After much discussion about the bottom conditions for which this holding power had to be achieved (good holding bottom, not soft mud), we were able to get their approval after we showed them the US Navy and our own independently verified holding power test data.
So for a manufacturer to get their anchors approved aboard these boats, you must have indisputable high holding power numbers by or from very creditable independent sources, regardless of whether the USCG expects to use the anchors regularly or not.
Much appreciated,
Brian
