North River Seahawk vs Offshore comes down to where you fish: choose the Seahawk for the bay, the local rivers and calm nearshore days, and an Offshore model when beyond-the-bar trips are your regular routine. Both are heavy-gauge welded aluminum, so the real decision is water, crew, trip length and trailering.
How We Ranked the Fits
This is a ranking of fits, not of quality. Each North River option is judged against the trip it suits best, using only what Y Marina lists for its boats: hull dimensions and features, fuel capacity, weight, power rating and whether the boat is in stock or special order. Five questions drive the order: where you launch, how far you run, how many people fish with you, what you tow with and where the boat sleeps between trips.
Y Marina is a family-owned Coos Bay dealership and an authorized North River dealer, so these are boats we sell. We have left out lengths, prices and arrival dates that the listings do not state; check current inventory for those.
The Ranked List: Best North River Hull for Each Kind of Day
Best for Bay, River and Calm Nearshore Days: 21' Seahawk OB
The 2026 North River 21' Seahawk OB is described on its listing as a heavy-gauge aluminum offshore and river boat. It is the one to rank first for most South Coast anglers who fish Coos Bay, the Coos, Millicoma and Coquille rivers and the ocean on good days. The listing shows a dry weight of 2,680 lbs and a fuel capacity of 70 gallons, which is a manageable tow and a useful range for a day of trolling and moving between spots.
Y Marina has more than one Seahawk package, including a stock-ordered Seahawk in Typhoon Metallic Green. The packages pair the hull with Yamaha four-stroke power, a kicker, hydraulic steering and a saltwater-ready trailer.
Best Used Entry Point: 2005 18' Seahawk
If you want the Seahawk layout at a lower entry point, the 2005 North River 18' Seahawk is listed with a Yamaha F90 four-stroke and an E-Z Loader trailer updated in 2025. It suits bay and river fishing with a smaller crew. Inspect any pre-owned hull and engine in person before you decide.
Best for Regular Beyond-the-Bar Runs: 2700 S Offshore
The Offshore S is built for rough water and long runs. Y Marina's special-order listing for the 2700 S gives it an 8' 6" beam, an Alaskan bulkhead, a 55-degree bow entry, extra-large fuel capacity and hydraulic steering. It is the step up for anglers who go after salmon, rockfish, lingcod, halibut or albacore past the bar and want offshore capability without a full-size cabin boat.
Best for Long-Range Comfort: 3300 WXL Offshore
The 3300 WXL is the large, wide platform in this comparison, with a 10' 6" beam, 33' or 35' hull lengths, a 55-degree bow entry, a spacious cabin and an expansive aft deck. It is for owners who want to stay out and fish with a bigger crew.
Best for Working Range and Fish Hold Options: 3500 WXL WA
The 3500 WXL WA is a walk-around with a 49° hull entry, 20° deadrise, a solid .250 transom and 28" interior side height. It offers expanded fuel and fish hold options for extended trips.

Trailering, Storage and Power: The Parts Spec Sheets Skip
A boat you cannot comfortably tow, launch or store will stay at the dock. The Seahawk listings pair the hull with a tandem-axle or heavy-duty galvanized trailer, and that is the kind of package that suits ramp-based fishing in the bay and rivers. The wide beams on the large Offshore models change where you can tow and keep them, so settle that before you place a special order.
Power matters as much as hull. The Seahawk listings show a Yamaha F200XD main engine with a T9.9XPB kicker, Yamaha pre-rig with mechanical 703 controls and hydraulic steering. A kicker gives you a second engine for slow trolling and a way home if the main fails. Special orders let you choose Yamaha power before the boat arrives.
Choose Seahawk If… Choose Offshore If…
- Choose the Seahawk if most of your days are in the bay or on the Coos, Millicoma and Coquille rivers, you fish one or two other people, and you want a boat you can tow without planning around it.
- Choose the Seahawk if you cross the bar only on settled days and want one hull that handles river water and the coast.
- Choose an Offshore model if you head beyond the bar often, run long distances for albacore or halibut, or carry a larger crew.
- Choose an Offshore model if range, a fish hold or cabin space matter more to you than easy towing and storage.
- Choose a used Seahawk if you want to start fishing first and add electronics and upgrades later.
Whichever hull you pick, bar crossings depend on conditions and your own judgment, not on a model name. Hull choice improves your margin; it does not remove the need to read the water.

FAQ
Is the Seahawk an offshore boat?
Y Marina's listing calls the 21' Seahawk an offshore and river boat, and it handles coastal water well. The Offshore line is a separate set of models built for rougher water and longer runs.
Are used North River boats for sale at Y Marina?
Y Marina sells pre-owned boat packages, and it has listed a 2005 North River 18' Seahawk. Current used inventory changes, so check the listings.
Can I special-order an Offshore model?
Yes. The 2700 S, 3300 WXL and 3500 WXL WA are listed as special-order opportunities, built with the North River factory to your requirements.
What power does the Seahawk use?
The 21' Seahawk listings show Yamaha four-stroke power with a kicker and a 300 HP maximum rating for the hull. The Offshore hulls are where fuel range and bar-day reserve become the deciding factors.
