Tidewater Boats calls its 3100 Carolina Bay the world’s largest bay boat. After stepping aboard at the 2024 Miami International Boat Show, I can confirm the claim: the 3100 is unquestionably large, and it retains the low freeboard, expansive casting platforms and fishing-focused features that define a bay boat. But it’s also much more than simply an oversized bay boat—Tidewater designed this model to be equally capable for serious anglers, family outings or even hauling an entire Little League roster.
Introduced into a lineup that began with five models in 2006, Tidewater has grown to offer 18 center-console models up to 38 feet and 11 bay boats. The 31-foot, 1-inch 3100 is now the flagship of that bay-boat range. Tidewater equipped it with a long list of standard amenities and several useful options so owners can tailor the boat for fishing, comfort or general versatility.
Boarding is effortless thanks to electrically actuated steps built into the gunwales on both sides of the cockpit: step onto the gunwale, press the actuator and the steps lower themselves; press again and they stow away. Stern seating accommodates four with individual seats to port and starboard and a two-person center bench. Lower the seatbacks and the stern converts to a spacious casting platform. For anchoring in skinny water, Tidewater offers optional 10-foot Power-Pole Blade shallow-water anchors mounted on the transom. Access to the bilge is simple—raise the center stern seats, and a motion-sensor light illuminates the space below.
The leaning post centers a 30-gallon aquarium livewell with an integrated tackle center and countertop. If you prefer more seating, an optional mezzanine-style leaning post can replace the livewell while retaining the tackle drawer. Rod storage is thorough: holders are positioned throughout the boat, including a rocket launcher above the tackle station and stowage channels inside both gunwales.
Under the fiberglass T-top—complete with a full-glass enclosure—the helm is laid out for both navigation and fishing. Twin MFDs from Garmin or Simrad allow the captain to run chartplotter and fishfinder functions without splitting screens. Comfortable Llebroc helm seats for two and standard joystick control make docking and tight maneuvers straightforward. Storage is plentiful with lockers built into the hardtop and seats. On the hardtop’s starboard side, just aft of the helm, a cold-water showerhead is recessed into the structure for quick cool-downs or rinsing salt off gear. The console’s head is large enough to change out of a wet swimsuit.
The bow houses a massive casting platform that dwarfs the optional 87-inch Minn Kota Instinct trolling motor. Beneath the platform are additional storage areas and a remotely operated windlass that retracts the anchor below deck. Even with that oversized casting area, the bow still offers comfortable seating for four adults with legs up, or it can accommodate up to nine youngsters. The wraparound bow seating features two forward-facing chaise lounges with adjustable backrests and a large sunpad forward of the console for two more passengers. Lift that sunpad and you’ll find a 100-gallon macerated fish tank suitable for the day’s catch—or plenty of cold drinks for a thirsty team.
Practical touches are everywhere: the gunwales are sprinkled with cupholders, rodholders and combo cupholder/rodholder units so anglers and loungers alike have convenient places for drinks and rods.
The 3100 debuted at the 2023 Fort Lauderdale International Boat Show with twin Mercury 400-hp V10 Verado outboards and an advertised top speed north of 60 knots. At the Miami show she appeared with Yamaha’s new 350-hp F350 V6 outboards, which Tidewater lists as providing a top speed in excess of 50 knots—still very brisk for a bay boat of this size.
We tested the 3100 on Biscayne Bay. While passing under the West Venetian Causeway Bridge, Capt. Justin Parsons fired up Lean On on the standard JL Audio system (8 speakers and 2 subwoofers). The stereo was impressively loud and cleared the channel—local boaters and pedestrians on the bridge seemed to enjoy the soundtrack. In the no-wake zone Parsons showed how the jack plates can raise the outboards vertically by 6 inches, a handy feature for navigating shallow water.
In the chop of Fishermans Channel the Yamaha F350s moved the 3100 briskly. A slight hint of cavitation appeared when the throttles were slammed—attributed to jack plates installed for Mercury engines that sat the Yamahas slightly higher than optimal—but even with the props an inch or two above ideal height, the twin 350s pushed the boat toward 50 knots. The Zipwake 450S interceptors kept her steady and delivered a confident ride in less-than-ideal conditions. For buyers seeking even greater speed, Tidewater offers the optional twin Mercury 400-hp V10 Verado Racing engines.
The Tidewater 3100 Carolina Bay is more than a very large bay boat: it’s a roomy, well-equipped, fast center-console built to serve serious anglers and families alike.
