Re: Caternary & Chain...
I get the impact of a gale and 4 ft seas in the anchorage. However, the impact of wind on rope v chain over the entire scale, not just when the first link is lifted, is going to be more applicable for the everyday cruiser in sheltered anchorages.
Without looking above, i think it was shown it takes 19 knots of wind to lift the first link of chain. However, the rope would be pulled taut by then. That must be two different angles on the shank for identical conditions.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
