Correction because the title says 1979 , but i saw a 305 and its identical, but Im thinking us 30 because the 305 was built until 1978, but now im sure its a 305, Its a beautiful boat, its an eye opener in keykargo, naples inlet, miami, everyone has to stop and compliment her, as far as hull and mast its taken a beating, the german caotain who sold her to me told me trust your boat, dont listen to what people write, ive sailed in very rough waters in the deepest part of golf more than 20 miles out, they said im crazy but i trust my boast, and in 20 knot plus wind it holds up, flies while minimun heling, I wonder if the ones bashing these boats have ever even seen one up close.
