About

Tomahawk Bay Marina is a marina near Portland, Oregon, on Tomahawk Bay with Columbia River access from Hayden Island. Its modern docks provide boat slips for vessels ranging from ski boats to sailing yachts, including slips over 50 feet. Covered and uncovered deep-water moorage options give boaters flexibility, while month-to-month rentals accommodate changing plans. Trailer storage may be included with a slip rental subject to the marina’s documentation process.

The marina combines dockage with shore power, freshwater hoses, pump-out stations, restrooms, showers, and controlled dock access. Electronic gates, camera monitoring, and security patrol support a secure home port, while Mt. Hood views, landscaped walking trails, and an active Portland-Vancouver boating community shape the experience ashore. There is no fuel dock or launch at the marina, though nearby facilities are identified for both. Contact Tomahawk Bay Marina to discuss available moorage and slip requirements.

Frequently Asked Questions

How old do you have to be to rent a boat in Oregon?

Oregon sets no rental age in law; what it sets is who may operate. No one aged 11 or under may operate a motorboat. A 12- to 15-year-old may operate a boat of 10 horsepower or less without an adult, and one above 10 horsepower only when accompanied by a person 16 or older holding a boating education card, or 18 or older for a personal watercraft. From 16, a boating education card is required for any powerboat over 10 horsepower, personal watercraft included.

Renters get a specific break: the Marine Board exempts them from completing the education course, but they must complete a watercraft rental safety checklist before departure. The rental company sets its own minimum age.

Do you need a boating license in Oregon?

Oregon requires a Boating Safety Education Card rather than a boating license. Administered by the Oregon State Marine Board, it is required for operators 16 or older operating a powerboat, including a personal watercraft, over 10 horsepower; there is no birth-date cutoff. Children 11 and under cannot operate motorboats. Operators 12 to 15 need a card for any motorboat, may run 10 horsepower or less alone, and need a card-holding supervisor 16 or older for larger boats or 18 or older aboard a PWC.

Renters may use a signed Watercraft Rental Safety Checklist as a temporary card for rentals over 10 horsepower, but no one under 18 may rent a PWC. Other exemptions include Coast Guard licensees and licensed commercial fishermen.

Where can you go boating from Portland, Oregon?

You can boat the Willamette River through Portland, the quieter Multnomah Channel, or the Columbia River and its islands. Launch at Willamette Park or Cathedral Park for a city run among bridges; currents and debris can be stronger after rain and near bridges. Sauvie Island Boat Ramp opens onto the quiet Multnomah Channel, which eventually connects with the Columbia. For direct Columbia access, use M. James Gleason Memorial Boat Ramp or Chinook Landing. Government Island is accessible only by boat and offers docks and a floating tie-up for a shore stop.

What are the most popular boating destinations near Portland, Oregon?

From Portland, boaters can plan Columbia River day trips to Government Island, Reed Island and the St. Helens Courthouse Docks. Government Island is accessible only by boat and offers shoreline stops, docks and a floating tie-up. Reed Island is a boat-in day-use park where visitors can beach their boats on the sand and enjoy the sandy beach or grassy meadows. The St. Helens docks provide an in-town waterfront landing with water and a sewage pump-out available.
