"I have an Ocean Alexander 42 which I have kept at Elliott Bay Marina since summer 2007. I asked around for a diving service to periodically replace zincs and generally tend to care of the bottom. I learned that Double J had an excellent reputation and I contracted with them to handle my needs. They have been with me ever since. They have always acted with the utmost honesty and professionalism. They have me on a specific schedule based on the wear they found and my usage patterns. They have also kept up with technology, and now furnish underwater photographs of the hull and running gear before and after each service. I am sure I will continue to use Double J Diving as long as I keep a boat in the water in the Seattle area."
