Sundance Marina & Dry Storage
Sundance is our full-service flagship on Tomahawk Island, with open wet slips for boats up to 100 feet, a travel lift and haul-out yard, and a high-speed launch. Moorage tenants get full marina club access: the pool, clubhouse, restrooms and showers, and gated docks, a short cruise from the main channel.
Sundance is on Tomahawk Island, the east end of Hayden Island, with its docks on North Portland Harbor, the Columbia's protected side channel. The main river is a few minutes out either way, and the Willamette meets the Columbia just west of the island.

★★★★★This place is absolutely outstanding! Grace and Mike go above and beyond — they're fantastic to work with. If you have a boat, this is hands down the best place to store it.

★★★★★Sundance Marina is an excellent marina and boat storage facility. Have used Sundance Marina now four straight years and it is one of the best decisions ever made.
Thomas K. · Sundance Marina
★★★★★Great staff. Very convenient option for boating — boat is ready and you just park it when done. Then it's stored and ready for the next time.
