When tying an F16 down, you should not allow anu wiggle room anywhere. Just using the mastrotation limiter line is insufficient in my opinion.
With respect to side stays, I must admit that I have a homebuild boat and my attachments points are heavier as I also use them to sheet my spinnaker of them. I'm guessing that they are also stronger on the Blades then on the Taipan, again because initially it was decided the sheet the spinnaker from them.
