What Our Clients Say
Finally, a warm boat
We have owned our Bayliner 4788 for seven years and finally added diesel heat. What a difference! We used Essential Sailing Industries in Friday Harbor. Jason and his crew added two 5 kw forced air units. They produce amazing, even heat in the boat and dried it out as well. They are amazingly quiet. I would highly recommend these folks as they were friendly and concerned about us being happy with the finished project. Jason, the owner, is great at problem solving and knowledgeable about the units and has installed many.
