We inspire Northwest families and friends to create on-water experiences and  lasting memories by providing best in-class brands and superior service from a locally owned, family business.


In 1986 we got involved in boating through exploring islands in the Puget Sound. We had so much fun that we felt we had to share this experience with as many people as we could. When you are out on a boat the stress melts away, and everything else in life takes a back seat. You get a chance to reconnect with your family and friends while experiencing the beauty of the Pacific Northwest.

Lake Union Sea Ray (now Union Marine), was founded by Kevin & Connie Roggenbuck in 1986 in Seattle, WA.  Their family loved boating in the San Juan Islands each summer and they decided to build a company that would invite other families to enjoy the boating lifestyle too.

The founding principles were to provide superior top in class brands, exceptional & personalized customer service, boating family event & life-style experiences to our community. With over 1,100 years of combined marine experience, we know boats much more than most dealers. We pride ourselves in having the most knowledgeable staff around. Our entire team is passionate about the boating lifestyle and will make sure you have the time of your life on the water.

Over the past 35 years, our dealership has been named the #1 Bayliner dealer in the world for eight consecutive years, Top 5 Sea Ray Independent Dealer in the U.S. for over ten years, Boston Whaler #1 dealer in the Western Region multiple years, Lowe Perfect Score & Rookie of the year 2018, Boating Industry Top 100 Dealer for eleven consecutive years.

In addition, we are a MRAA 5 Star Marine Certified Dealer and a Master/Ambassador Dealer for Brunswick, promising your new, used or brokerage boat buying and ownership experience to be best in class.
