2020 Sea Force IX 51 Center Console/Sportfish

Sea Force IX 51 was launched in 2020 and she truly is a one-of-a-kind custom fishing machine.  If you're looking for a true one-of-a-kind boat that checks off all the boxes, this boat must be added to your list.  She's exceptionally different than any other manufacturer out there with features like no other.  Her profile is unmatched along with all of her top-quality fit and finish items that make this boat stand tall in a class of her own. Her plateau is based upon having the performance and speed of a center console matched with the comfort, luxury, and sleeping accommodations of a sportfishing boat.  Her deep V hull and design provide a great ride in both calm and choppy sea conditions getting you to your destination without any hesitations.

The Sea Force IX 51 is not only a high-end, and completely tricked out offshore fishing vessel, she's also the perfect family boat for day cruises, snorkeling/diving, and anchoring up at a favorite sandbar.  Her tower serves as a great spot to drive while hunting for fish offshore or to sit back and hang out and watch the world around you at the sandbar or offshore. The helm is another great area with state of the art Simrad electronics and completely closed in and protected from bad weather elements.  Her cabin offers a great layout with every inch of space being accounted for.

The Sea Force IX 51 is also meant for long-range fishing trips whether they're one day, overnight trip, or a couple of nights and days offshore, running out of fuel and power shouldn't be a concern or having to worry about keeping food and drinks cold or stowed away.  Some key features for this:
