Brand New 25′ North River Seahawk “The Best of Both Worlds” Part 1

The Brand New North River Seahawk 25’

Choosing the right boat for the right situation is not easy. So much thought goes into every build, and every custom feature we add for each individual customer. The needs of the customer here were complex as they wanted an offshore capable fishing boat, but also a vessel that can play hard when at the lake with their family, or even the occasional camping trip. Both worlds collided into one build that features something for just about everyone.


We chose the North River Seahawk model which features an aggressive entry and exit while using a .250 heavy gauge aluminum bottom with a true reverse chine. The standard features on this model really make a strong case for a pure fishing boat. Dual suspension seats on swivels, 110 gallons of fuel, trim tabs with an led light indicator, and two benches that offer sealed water-tight storage just to name a few. Sticking with the offshore theme, we deleted the wood floor and went with a .190 welded in aluminum floor, with side channels and scupper drains on deck. Draining the deck quickly, and leaving all debris on top of the scuppers so as not to interfere with bilge operation. The deck is also coated in a non-skid material for safety, and features a large in deck fish box. Top selections vary for the Seahawk model, but they feature several configurations that fit most everyone’s fishing or pleasure boating situation. Available in a convenient folding top, a full hard top with an Alaskan bulk head, or a rigid frame removable top with canvas skin, in this instance we took a combination of each. Hard sides with sliding windows, a rigid welded structure, and canvas skin covering the helm. While taking shelter from the ever-present rains, or basking in the brief summer sun, comfortability is not overshadowed by the aesthetic value. Port and starboard net and gaff holders keep the deck clear, and offer additional rod storage for easy access when the bite is on.

With modern day efficiency, power, and run ability in mind, the new “old school” work horse of the single Yamaha F150 is seldom outmatched in value or longevity. Redundancy throughout the boat’s systems including electrical and in gauges, meant twins were the perfect fit. Yamaha’s T9.9 High thrust kicker motor rounds out the power plant, for endless hours at trolling speed. While mounting the motor, the kicker is plumbed for a hot wash station, and the bracket is the retention basin. This gives you the opportunity to warm, and wash your hands, or start the end of day clean up early. The two-rung boarding ladder makes getting back on board easy, and combined with our portside boarding door, getting everyone on deck without climbing over the transom is very convenient and safe.

On deck amenities include a raw water wash down system, in-floor fish box, transom fish box, and a removable table in the cabin for lunch breaks. Available room for storing fish on this boat is not a problem, making it the perfect choice for your fishing adventures.


Stay tuned for PART 2 of the build after the electronics and a few other custom additions are installed…..

Duckworth Offshore: The Game Changer

Gene and Michele Gorham are avid saltwater anglers that hail from Anchorage, Alaska. Like many of our out-of-area customers, they searched for a Duckworth Offshore dealer they could trust that has the experience and capacity to build them the boat of their dreams. The road led to 3 Rivers Marine.

Ultimately their new boat would dock in Seward, Homer and Whittier, Alaska. They valued a boat that had the range for multi-day excursions in the remote reaches of Prince William Sound, the seaworthiness to handle the rugged offshore conditions in the Gulf of Alaska, and the creature comforts to enjoy time with their family when boat camping. The Duckworth Offshore 26’ with an extended cabin was the ultimate choice.

From the initial meetings with Andrew and Scott, the Gorham’s knew they had selected the right people to craft their ideas and needs into a boat that will serve them well for many years. They selected a 116” cabin that would give them the space for a full dinette (convertible to a sleeper), full stand up head, galley with a fridge, sink and cooking surface, and plenty of storage. A Lewmar Windlass anchor puller was a necessity for halibut fishing. An electronics package with sonar/chartplotter/radar displays at the helm and aft station, a high-powered trandsucer/sounder module, diesel heat and custom tackle storage also were big on the list.


The Gorham’s take a pit stop at the top of Turnagain Pass on their way to Seward, Alaska.


Solid reliability, fuel efficiency and the pure power of twin Yamaha 150 outboards for long hauls and rough seas, and a Yamaha high-thrust kicker for trolling up those hefty Alaskan Kings.


Comfy dinette with suspension seat on swivel base.


Raymarine ES Series 9″ sonar/chartplotter/radar display, sound system and L.E.D. lighting at the aft station. Everything needed to hunt fish and listen to tunes on the fishing grounds.


Duckworth’s clean dash design with all gauges and switches, plus a flush mounted Raymarine A series 12″ sonar/chartplotter/radar unit.


Full galley with freshwater sink, 12v fridge and cook top. Plenty of room for food prep as well. Plug in to shore power and fire up the vacuum packer at the end of the day! Too easy!


Shore power for lighting, sound system, fridge, plug-in appliances, vacuum packer and all the niceties while boat camping, without worrying about battery draw!


Professional, clean, organized electrical rigging installed by the rigging technicians at 3 Rivers Marine. Nobody is more thorough and precise when planning and rigging the electrical system in your boat.


Gene’s family has been hauling in the Halibut, Lingcod, Kings and Coho all summer in his 26′ Duckworth Offshore!


One final decision after the boat build was finished and all the outfitting rigged. What to name it? We feel that the Gorham’s couldn’t have picked a boat name that better describes how this boat has effected their fishing experience: The Game Changer.

The first summer with their new Duckworth was a huge success. We were through-the-roof excited to hear of the great fishing experiences the Gorham’s have had, their satisfaction with their boat, and the choice they made by building a Duckworth Offshore with 3 Rivers Marine.

A Dream Realized: Alumaweld Blackhawk

Dan & Alyssa are a young couple from Snohomish. They have been dreaming of a new boat, one that would allow them to explore Puget Sound and take advantage of great fishing and crabbing. They want to instill their love of the outdoors with their growing family, and what better way to do so than spending summers on the water. They needed a boat that would provide the family a soft ride, plenty of space, and safe for the little one. The 3 Rivers Marine crew wanted to help this couple fulfill their dreams and turn them into a reality.

The Alumaweld Blackhawk 202 was the perfect boat for the young couple. This model features a heavy-gauge welded aluminum hull with a deep Vee, offering a smooth ride in the open water. The standard Alumadrive bracket pushes back the main outboard from the transom, increasing the amount of deck space, adds room for an in-transom fish box and allows for the safety of a full height transom. With models in 18 and 20 foot, it’s a great choice for anyone looking for versatility and comfort ability in one hull.

And with a few special modifications, we turned their new boat into a saltwater fishing machine, with all the creature comforts.

Outfitted with the new Yamaha F115, this redesigned outboard model is lighterweight, has a larger alternator and adds and extra 1000 RPM’s compared to its predecessor. Yamaha High-Thrust 9.9hp kicker motor which makes for easy trolling and plumbed with a hot wash basin makes for easy cleanup.

Scotty electric downriggers with a long boom sets this couple up for successful salmon fishing in the Sound.


The electronics configuration is dialed, with a Lowrance HDS 7 sonar/gps unit with a NEEMA Network Connection that fully integrates all the necessary operating information on the screen, removing the need for a cluster of gauges on the dash, plus a Sonic Hub Sound System. We went fully digital on this one!

Being stored outdoors on a wooded property, Dan & Alyssa needed to find a solution to keep fir needles from littering the deck and getting into the bilge. We were happy to take on the challenge. 3 Rivers Marine engineered a custom slant-back marine grade cover that will keep their boat looking great, throughout the seasons.


With a little hard work and customization, Dan & Alyssa are ready to have some great on the water experiences for years to come!
