He was born in 1877, heir to an important Piedmont family.
From his earliest days, Carlo had a great love of the sea, so he enrolled in the naval academy Regia Accademia Navale in Livorno. He subsequently graduated with a degree in engineering.
He was brother-in-law of the Admiral Count Umberto Cagni, a valorous officer and great explorer; it was from him that he would learn the first secrets of the sea. He was initiated into regattas by his inseparable friend Baron Cencio Massola, a member of the Central Management Committee of the R.Y.C.I.
In 1921 Massola owned the famous yacht Artica, which the Duke degli Abruzzi had had built and which won the France Cup, and it was on the Artica that Carlo Nasi got his first sailing experience. Subsequently, Nasi would buy LEI, a 6.50 metre, but the year after he changed to a 6.50 S. I. Eolo, the boat on display here, in which he had great success in the Genoa regatta in 1924. The same year saw the trio Nasi-Moscatelli-Massola as the first Italian Olympic team in history at Le Havre. 
Carlo Nasi has a series of successes both in Italy and abroad with his boat Mebi, the 8 metre S. I Clara and the 12 metre S.I. Costaguta.
He married Caterina (Aniceta) Agnelli, daughter of the founder of FIAT Giovanni Agnelli. The couple had 5 children.
