Think about a windy day with the anchor well set. Now think about how much force you have to use to pull the boat toward the anchor until the line gets vertical enough to free the anchor from the bottom. That's how much force your windlass will need. . . . When I studied this issue a while back I concluded than none of the "affordable" windlasses had both the power and speed to meet my needs. The least expensive windlass I saw that met my requirements was $1,000 or more. ... And dealing with that 4 feet of chain is a challenge too.
