Jack Duffy-Protentis, founder and CEO of eSki, grew up in New England close to the water where he fostered a love of recreational watersports. From a young age, he has always had a fascination with engineering. Jack has combined these passions together to create eSki and develop our distinct electric-powered personal watercraft product. 

Jack was diagnosed with Stargardt disease in 2006; Stargardt disease is a rare genetic condition that affects the eyes, causing a buildup of fatty material on the macula, resulting in a majority blindness in the center of the eye. Despite the immense challenges caused by Jack’s disability, he has never let it get in the way of achieving his goals. In 2021, Jack received his Bachelor of Science in Mechanical Engineering from Worcester Polytechnic Institute.
