Yardpro: Congrats! I have a Sagitta-30, hull number 33. She has been mine for 5 or 6 years. Home port Sitka, Alaska.
Yellowchair: It that the yellow hull one in California? I visited her a couple years back, talked with the owner. She used to have a black hull when Bill had her.
In general... well built, solid old-school fiberglass. Basic European sensible design. She is much better a sailboat than I am a sailor, very forgiving. I have been living aboard for several years. Summers roaming SE AK fjords.
Checkout the "yachtdatabase" website, select "owners contacts", go to "S" and you will find eight Sagitta-30 owner contacts.
