Our Customers Love Us. You Will Too.

Ethan’s knowledge base exceeded my expectations. He demonstrated professionalism-and provided excellent marine improvement/repair services that were completed in a timely manner-paying very close attention to detail.

We would HIGHLY recommend SeaNergy. Had a few boats, tried many companies......but Ethan and his company are Superior to All! Extremely knowledgeable, reliable, professional and prompt.

He came highly recommended, and true to the recommendation, his services so far have been top-notch. I applaud his professionalism, patience and top service provided so far on our first trip to the Bahamas in our new vessel. I don't hesitate to recommend Ethan and his company to anyone!
