If you were to compare this image to the one with the bow sprit buried into the sea you can guesstimate the arc that the bow was rising and falling. Keep in mind that this was only 3-4 foot short period waves. When these photos were shot the wind & storm was winding down and perhaps only 30 knots. At the peak this storm hit 40-45 knots but only lasted a few hours.
The bow of this boat is rising and falling perhaps 6-8 feet. Try to picture your vessels bow rising and falling 6-8 feet with an anchor on the bow... Ouch!!
Please note the remaining pendant and how it is caught and held by the Delta anchor so tightly that it is bending the pendant and keeping it from straightening out.
