Re: Anchor Rode Spectra?
You don't need to worry about it breaking. It'll tear hardware out of the boat before the line snaps if you sized it right. I would also talk to a manufacturer about it. Sounds like the system is overbuilt which would further reduce any shock absorbtion.
Anchor rodes should stretch so it doesn't snatch the anchor off the bottom.
