Cay Electronics is a marine systems sales, engineering, and service company specializing in marine electronics and electrical equipment, marine software and computers, refrigeration and air conditioning systems and reverse osmosis water makers for yachts and powerboats. At Cay Electronics we take a unique approach to marine electrical and electronic engineering. We call it the total yacht concept. Whether you come to us for a repair or a refit, or your boat is still under construction, we consider the impact of our work on all the components of your boat, resulting in an integrated system that is more than the sum of its parts. The total yacht concept also means being where you need us. We started the business in Tortola, British Virgin Islands in 1982. In 1990 we added a branch of Cay Electronics in Portsmouth, Rhode Island to extend our service throughout New England and the Atlantic Seaboard, as well the Caribbean. Today we have more than twenty-five dedicated engineers, technicians and customer service specialists committed to providing expert consultation and worldwide service, including installation, repair and product sales. We invite to you to visit us at either of our locations or via the Internet. We'll be happy to talk to you about upgrading your boat's current systems or designing innovative systems from keel to mast.
