Are the mainsails the same cut?
Are the spreaders at the same angle?
Are the diamonds the same tension?
Are the rotation and luff tensions the same before getting overpowered?
Are both sailors pulling the mainsheet on as hard, with the same purchase?
Did you swap boats between sailors and do the same tests twice?

I have found similar differences in hull flying and pointing ability, when I use to swap Mosquito's which are one design, with other sailors. I thought it was my boat that didn't point, but it turned out it was just me. frown

Also it is probably worth mentioning, that the Blade hulls you are commenting on are Vectorworks Blade hulls, as they have small differences in shape and volume to Blade hulls built by others.



Same questions from me.

If the heavier boat (and I assume the Viper is) flying a hull earlier; the sails MUST be generating more lift and so they MUST be cut differently or trimmed differently.

we need more info to understand what was going on!
