Getting a new 190’ vessel ready to transit from San Diego to Seattle. I asked how much chain was on each anchor. No one knew. Not even our corporate engineering division. Typically it is 10 - 12 shots of chain. One shot = 90ft or 15 fathoms. We were doing ops one day in very deep water, so I decided to take that opportunity to lower one anchor and let all the chain out carefully to the bitter end. Making note of each shot as it came out of the chain locker and over the anchor windlass and into the water. Due to the water depth the anchor never touched bottom. The windlass was a new electric/hydraulic unit. The chain handler was the correct size for the chain. As soon as we attempted to begin hauling in the anchor we blew a hydraulic line on the system. 2 more tries produced the same result. So, here we sat with an anchor and 900’ of chain hanging in the water. A call to the windlass manufacturer was made. The manufacturer said there was no way that windlass could hoist up that much weight. They expected scope of about 4 to 1. So, when hauling in you’d never need the ability haul the entire weight of the all the chain and the anchor. So, we brought cutting equipment up to the bow. I backed down as hard as possible, which made the chain and anchor lead out in front of the boat. Then we cut it with a torch. Leading it out made the length of anchor and chain stretch out across the bottom and not fall in a pile. I was attempting to make it easier for one of our other vessels to drag a large anchor chain grapple across the area and snag the chain, then retrieve it in sections. I got good GPS coordinates of the exact location. The vessel dragging for the chain got it on the first pass. But, for years my boss used to kid me and say, When you say drop the anchor, you really mean it!! Turned out none of the other captains with our company realized these new windlass’ were incapable of hauling the entire weight of our typical anchors and chain. Lesson learned.
