After reading the story, some tech talk about snubbers seems apropriate.
The perfect snubber would be very stiff on deck
and through any chafe points. The middle part of the snubber would be very flexible and shock absorbing while not melting or parting.
Nylon stretches 30 or 40% before failing? (from a prior post) The Idea of increasing line diameter only makes the snubber less effective, transfering higher shock loads to the rode. Smaller diameters just fail.
How about 300% stretch with the ability to do it all over and over untill the storm is past? The answer is polyurethane
pendants that have weathered big storms. When big gusts hit the boat sits back softly. When the bow veers of the wind the change of direction is slow and smooth. I have seen video of this in high winds and have been using one for several years.
These things are used to secure moorings with little scope
and high surviveability in storms. To date the cost has limited widespread acceptance. Just like air bags in cars.
These things are not toys like the rubber things that you wrap a line around. When I brought mine to a class, somebody said "is that for a tug boat?"
The total lack of information about this technology in the cruising world just blows me away.
After reading the story, I am considering doubling the length of my snubber.
We use a chain lock on deck
but with out an effective shock absorber, something will fail.
Our boat does work well with a 4 foot diameter drogue
fixed to the aft end on short tether and I am curious about the Idea of hooking one to the anchor rode too.
