longer is better?

A good post from our Fabulous Forums, brought to you by Marlow Ropes

I just purchased a Viper 830 and need to upgrade the running rigging.  I’d like to do this over the winter, but am reluctant as I wont be able to sail the boat, to see if the current rigging lengths are correct.  I measured the old sheets and they are 55′ w/ 12′ of taper each, which seems on the short side.

Could the peanut gallery please chime in with thoughts or any riggers with a best practice method for determining length please pipe up?  A internet search turns up 2x boat length for symmetrical kites and 2.5 boat length for asymmetrical kites. The Viper is 28′ long and we companionway launch the kite.  Thanks!

Hop on in.
