Capt. John Page Williams Reviews Sea Pro 320DLX Offshore



"The 320 DLX Offshore offers a sturdy build and a wealth of features."

Details such as finished hatch lids, the massive hinges of the side boarding door, and the way that door’s folding swim ladder ($918) stores in a dedicated rack make the Sea Pro 320 DLX Offshore’s quality stand out.

Interior and Accessories

The 320 DLX’s console changing room boasts a wide door, 6 feet, 2 inches of headroom, a porcelain toilet with holding tank, a sink, and a bench seat with storage, plus access to helm electronics.

The helm features a proprietary Connect boat-control system based on twin Simrad NSO19 Evo3 electronic displays. A key fob activates the system, but there’s a master switch on the dash too. 

A pair of macerated, in-sole fish boxes lie port and starboard beside the helm. Beneath and behind the helm seat, you’ll discover an 80-liter cooler on a slide, and above that is a 36-inch-wide freshwater sink with a hinged lid. Overhead, an ingenious freshwater shower flows from a stainless-steel grate. The hardtop’s aft edge and the transom each hold a five-rod rocket launcher. The gunwales hold 11 more, and two horizontal racks lie recessed into the starboard topside. A folding transom bench seats two.

An electrically actuated table makes the bow cockpit a picnic area, a sun pad or a casting deck. Seating is plentiful, and a built-in dry box includes twin USB chargers.

A large, finished hatch grants easy access to the boat’s batteries. In between massive gelcoated stringers sits a polished stainless-steel sea chest with two pumps feeding 30-gallon pressurized livewells in the transom corners. The sea chest minimizes the number of through-hull fittings. We found the plumbing and wiring neatly arranged.

We liked the nimble, sturdy feel of the 320 DLX on a snotty day. Handling proved crisp and dry, with a soft ride from the 24.5-degree deep-V hull. The twin Yamaha 300s provided a low cruise at 28.1 mph, high cruise at 31.9 mph, and top-end of 49 mph. We liked that the 320 DLX rose onto plane easily at speeds in the midteens, suggesting a wide range of usable speeds to fit conditions. The boat also proved stable on the drift.

  • Bilge access is laid out well, and the finish is excellent.

  • Hull proved to possess a solid feel and good maneuverability at speed.

  • Cockpit scupper system drains quickly.
