Wouter,

Your info is not quiet correct.

The Blade F18 had its rig in place but not tensioned. Same went for the Hobie/Nacra & the Aging Tornado. If fact the Aging tornado was about 120mm of flex & the Marstrom (93 model) was about 55mm. They all had their rigs in place. The extra weight from the rig would affect your comparisons.
