COVID-19 Statement Click to view >

COVID-19 and O’Brien: In the midst of everything going on, O’Brien Watersports is still up and running. As some of you know, our headquarters are based just outside of Seattle in Snoqualmie, WA and on March 23rd the governor mandated a stay-at-home order. Prior to the announcement, we made the necessary changes so that we are capable of working from home, which is what we’ll be doing until the situation improves. All of our daily operations are still functional with the exception of customer service being able to receive phone calls (if you leave a message, they will call you back). Alternatively, we recommend that you reach out to them via email at for faster and more efficient assistance.

For anyone who has placed orders recently, there is no need to worry. We are still capable of processing and shipping orders from our warehouse in Texas and will continue to do so until further notice. As things change, we will do our best to keep you informed. Until then, stay safe and we can’t wait to see you back out on the water.
