Re: Anchor Rode Spectra?

re: chain/cable - I am no expert, but sufficient chain can act like a shock absorber. Clearly does not stretch, but it has a lot of weight and the links can be tight together or loose; so chain can absorb some shock. I've not seen it on your scale, but on a smaller scale in a gust it is the chain that seems to absorb most of the stress. Need a lot of it though.

As for Spectra, think of it as a steel wire (which happens to be made of plastic) - similar, even lower stretch, similar breaking strength. How would your deck hardware react to a sudden pull on steel cable attached to the chain length you are considering?

Re: Anchor Rode Spectra?

For strong winds you need some stretch in the system.
So you will need to use a nylon snubber as you would with chain, in fact it will needed at slightly lower windspeed than when using chain as there will be little catenary which gives chain some give at low wind speeds (unfortunately this effect with chain is all but lost at high windspeeds when its needed most)

The snubber will be difficult to tie to the slippery spectra with a knot that can be done easily. Possibly an Alpine butterfly bend would work. Something like Klemheist I think may slip, but you could try it.
An alternative would be a series of permanent loops in the spectra, but its a less than elegant solution, and the reduction in knot strength would need to be allowed for.

Spectra is strong and chafe resistant which are important qualities in an anchor rode, if you can work out how to incorporate the stretch it could be a good solution.
