  • Testimonials

    In 2005, the Port of Sunnyside Club, Inc. made the decision to scale back the operation of the marina and embrace the use of Outside Contractors to perform the work we would no longer offer to our boaters. This decision has turned out to be the best possible business model for the marina, but it could not have been possible without the efforts of companies like JL BoatWorks. Our Outside Contractors are a direct reflection of our marina operation. We need to make sure our Outside Contractors work with the same integrity as we do. I often explain to my boaters that the reason JL BoatWorks is here at the marina working on their boats is because I have complete confidence in their ability to perform the work and to stand behind their work. Jason Longnecker, the owner of JL BoatWorks, visits the marina and checks all of the boats his company shrink-wrapped after every snow storm. It is this kind of dedication that makes me comfortable recommending JL BoatWorks to our boaters for any of the services they offer.
