Yup, that was the plan. The 300' of chain + nylon would suffice for around 90% of our anchoring. The extra length given by the Spectra/Dyneema would be used in deep water, ice avoidance, or storm.

Good point. I forgot that it's recommended that constrictor knots use a cord at least 1/2 the diameter of the rope it's being used on, so the cord would be freakishly thin, and you're right in that they apparently won't hold anyway.

My hunch is the weakest point in any rode will be where it goes over the bow roller, especially if there is any wave/surge action. Will look into anti chafe strategies...
