If the system used to handle the anchor chain is right, the chain comes in or goes out at the push of a button. If it is wrong, all sorts of problems can occur, typically requiring human intervention to prevent and or remedy the issues. In this report we will show you a few of the details we employ to get this right.<\/p>\n

We are using a Maxwell V4000 windlass on the FPB 64 (same size as on Wind Horse<\/em> – FPB 83). It is oversized on the FPB 83 so it might be considered ridiculous on the FPB 64. But we can afford the weight and the massive shaft, bearings, gears, and motor of this unit guarantee a long trouble free life. Proper fit of chain to the chain wheel (gypsy) is essential.<\/p>\n Note the chain stopper ahead of the windlass. We know from real world experience that this will work in horrible conditions.<\/p>\n The bow rollers and their supporting structure provide several important functions. First, the rollers and structure form a stop against which the anchor is winched hard. When all the way home, this prevents the anchor from moving at sea (which is annoyingly noisy). Next, the dual large diameter rollers reduce chain friction. Third, the angled rollers are designed so the anchor self launches, while reducing the load on the windlass as the anchor stock first turns the corner of the lower roller when winching the anchor home.<\/p>\n The UHMW rollers have a dual groove. The inner is for the chain link and the outer for the anchor stock.<\/p>\n The eye at the top between the structure is a fairlead for everyday use with the snubber line. If you were to ever hang behind a parachute anchor it would also lead through here.<\/p>\n Every so often the anchor will start to come around the rollers at 90-degrees or upside down. Dimensional allowance has to be made for the anchor, and the shackle with which it attached to the chain, to rotate into the correct orientation (which it will do on its own).<\/p>\n","protected":false},"excerpt":{"rendered":"<\/p>\n
