I was hoping for someone to give specific dimensions of a new Goodall spinnaker. Here’s why.

I have just bought a Mystere 5.0 XL, one of the grandfathered (but non-competitive) F16 boats. It is heavy and slow (330 lbs with a new Portsmouth of 76.5). Most people don’t know that for years it was raced with a DPN as low as 74 so if I sail it solo (light) and mount an easy-launch spinnaker it should be a killer in an open B Fleet (H16, P16, Dart 18, etc.) And all done for less than $3000.

I have found a cheap and barely used 1997 spinnaker that came with the boat when it was new. However, Jeff Bowers who sails a Mystere 6.0XL noted, “Over the last few years spins shapes have gone through a great deal of changes. The spin I bought for my 6.0 in 1996 is a completely different shape from my current one. Smaller, flatter, and much faster.”

OK then, I guess I should to re-cut this old chute but to what design. A little guidance would be appreciated.
