In the 17th century, in Trieste, worked 40 sailmakers, one of their collaborators Ernesto Zadro, in 1917 opened his own loft.
The results of his experience, joined to the study of aerodynamic, carried the name Zadro on the racing fields, where many famous helmsmen (Straulino among them) gained victories in the whole Europe and in Olympic races.
The orders came from the whole Europe, and, to Ernesto Sr. joined his son Ernesto.
After the 2° world war, we started in working with Class C yachts and metric classes.
At the end of the years ‘60 the I.O.R. is born, and starts working in the loft Ernesto Jr. son, Aldo (3° generation), at the same time we gain other victories in fin keels classes.
In 1981, first in Italy, we test the Mylar Kevlar.
As in 1917, we work without precise limits between private and professional life, and the relationship with the customer is extremely direct.
We remain a „human“ firm, strictly connected with the modern technologies (we use since many years the computerized projecting/cutting joined to a sophisticated sofware for simulation) but we do not forget our origins.
As special prize, in the 2002, we are elected best Italian sailmaker, and arrives in the loft, after an experience by an important american sailmaker, the nephew Federico (4° generation, often on racing fields)
In 2003, we open a new loft, but our working way, the honesty and the seriousness to offer you a good product, remain always the same.
