Tomahawk Island Marina

About

Portland's premier Marina since 1971! We are conveniently located on the Columbia River in Jantzen Beach, near Hayden Island. We offer quality covered or uncovered deep water boat moorage slips for vessels up to 60′ in length. All boats are welcome - Power Boats, Pleasure Boats, Speed Boats and Sail Boats. We're known as being one of the cleanest, safest and friendliest marinas around and our tenants enjoy easy access to the Columbia River and all that it has to offer. We have a few slips open and are looking for some good folks to join our vibrant boating community!
