Merits of Dual Backstays (Non-Running)

[tager]

I was also under the impression that most rig failures are forestays, followed by cap shrouds.

My problem with dual, non-running backstays is the increased probability of failure.

Single backstay: 2 end fittings, 1 turnbuckle, 1 piece of wire, 1 adjustment

Dual backstay: 6 end fittings, 2 turnbuckles, 1 fishplate, 3 pieces of wire, 3 sets of bolts and nuts for the plate, 2 adjustments

Then again I have never seen a single backstay fail either. So the extra safety thing is much hype.

I like by doubles though - very easy to hang things there (e.g. solars) and very easy to tension - just a tackle, not an expensive and failure prone hydraulics.

The purpose is to move the tension towards one corner or the other, only really noticeable on racing.
