Welcome to the page of Katabasis Freediving and Sailing, an amateur sports association founded by Carlo Boscia in 2005 and based in Baratti, Tuscany (Italy). We are a school and training centre that has chosen SSI Freediving, DAN and UISP for its educational activities.

We organize courses and seminars in freediving, spearfishing and sailing, as well as cruises and sports trips in Italy and around the world. Love and respect for the sea are values that we aim to transmit to our students and members during our activities, targeting adults, children, beginners and athletes.

We are also active in the social sphere, in team building and in the world of education, using sport and the sea as great resources for a better lifestyle.

Carlo Boscia Katabasis


Carlo began his teaching career in 1991 as a sailing instructor and in the autumn of 1994 made the Atlantic crossing. In the meantime he became a scuba diving instructor and finally began teaching freediving in 2004. In 2005 he founded Katabasis, the first freediving center in Italy, where in addition to holding freediving courses and training, he organizes events with the most prestigious names in national and international freediving, creating his own teaching style over the years.

Since childhood he has always been a mountain-loving skier who with the sea has always had a somewhat difficult relationship not being a great swimmer but … in 2011 by chance, he discovers apnea and the whole wonderful world in which today he dives as soon as he has the chance. He goes through all the stages with Katabasis until becoming an instructor fully espousing the philosophy of approaching the sea with a smile and great respect. He likes to call himself a mountain man in love with the sea. He is in charge of Apnea courses in Modena.



Born in 1989, a chemical expert with a passion for science and nature, he approached freediving in 2015 by chance. A former competitor in various disciplines of contact sports, he began his journey in the world of Apnea in small steps in 2019 where by chance, in the middle of the waves during a spearfishing session, he met Carlo Boscia, founder of Katabasis. A great friendship was born that would later lead to his training as an Freediving Instructor.
“The sea is a wonderful place, let’s take care of it!”



Spiritual guide of Katabasis, the only specimen of “Elban Plutiode with Satin Hair”, thief by vocation, bastard inside, in 2012 he obtained the “Pool Freediver” certification… don’t you believe us?
