Experience matters

For over 38 years our locally owned family business has been inspiring Northwest families and friends to create unforgettable on-water experiences and lasting memories. We provide best-in-class boat brands and superior service, ensuring exceptional boating adventures in the Pacific Northwest.

"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."

- Kevin & Connie Roggenbuck
Family Owned Since 1986

We Have You Covered

Captain Service

At Union Marine, boater education is one of our top priorities. One of the most essential ways we educate boaters is through our certified boat delivery service (AKA "Delivery Captain").

When you receive a boat from us, we walk you through the basic operation of the boat based on your level of experience. From there we introduce you to our service team who will help you understand what's involved in owning a boat.

Owning a boat should NEVER feel like a chore. When you're with Union Marine we work to ensure you are on the water and enjoying your boat all season long.

Our Story

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 best in class brands, exceptional personalized customer service,  and boating family event & lif-style experiences to our community. With over 1,100 years of combined marine experience, we know boats! 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.

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's #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 to our accolades 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.
