in my experience...
I have learned that spinnakers and my girlfriends are like oil and water... they don't mix without allot of shaking....

Somehow Spinnaker became a 4 letter word in my house and i couldn't even say it without being sent to the couch to sleep.

I am sure there are those gf's/wifes/etc that enjoy flying the hull downwind with the skipper letting out yelps of joy and fear... but i haven't had the pleasure of meeting one...
