End for ending an anchor chain is common practice and in many countries/places a chain can be re-galvanized rather than replacing if not worn excessively. Nylon rode is superior in every way. Lose the chain. And thus speaks a man who is in total ignorance of what he says. You might want to read up on just how an anchoring system functions. For example, how much does the "catenary effect", for want of a better word, effect anchoring system effectiveness. Or perhaps the effect of underwater conditions on anchoring components, for ocean floor consisting of Mud, Grass or Seaweed, rocks or coral growth. And before you fly off on a tangent it might be well to state that chain anchor rode has been considered a safety factor since at least the 1700's and that considerable investigation has gone into determining its effectiveness. For example I find research such as: 2012 - Engineering Thesis from MIT entitled "Simulation of the catenary effect under wind disturbances in anchoring of small boats". Have you read that? Or, From an Australian maritime regulation, "Where a rope and chain anchor line is used, it is recommended that the length of chain be at least equivalent to the length of the vessel." Or, From the U.K.: "The Merchant Shipping (Cargo Ship Construction) Regulations 1997 and The Merchant Shipping (Passenger Ship Construction) Regulations 1998 provide that: (1) every ship must be provided with anchor handling equipment together with such anchors and chain cables as are sufficient in number, weight and strength having regard to the size of the ship; and (2) this equipment must be tested and certified by the Certifying Authority." And your authority is what? Your imagination? Or perhaps "investigation" from a company such as Rocna, which is so obvious in their frantic attempt to justify their product as to be almost a joke? Rather than the false address of "greghall@yacht_master" one suspects that it be far more accurate descriptive to write, "biggestFool@the_dummy_convention". -- Cheers, Bruce |
