PSI Aircover

"This is the jib sock that really works!"

Piet Schol, a fanatic yachtsman, experienced problems with the traditional jib sock so often, that he decided to develop an improved version. His jib sock would combine everything he needed: fast, flexible, easy-to-use and excellent protection. This creation would become known as the 
''PSI Aircover''.

''Using my old jib sock always required a lot of effort and power. In spite of that, the result always remained inadequate. The effect of strong winds made my blood pressure rise, I can tell you. And that was exactly where I found the inspiration to create the PSI Aircover.''
