Hi William

Here's a few:









"Red Alert" was a very light ply construction Mozzie, built for cat rig only with twin forestays. It was changed to a high bridle configuration and was able to handle it.

As far as the loads on the boat go, the loads on the bows from the spinnaker are not as much as you get from the forestay bridle sailing upwind. It is nothing like the effect of a gorilla with a 10mm mainsheet and a six-to-one purchase.

There is some extra load where the beams are attached to the hulls as these get twisted forwards or backwards every time you gybe. Having said that we have seen no problems after 5 seasons of spinnaker use (and the South Africans have been doing it much longer than us - with 100% timber boats to start with).
