The Bayliner T18 bay boat is the smallest model in Bayliner's Trophy line, an 18-foot center console built as an affordable family-and-fishing platform. Its relatively flat bottom gives it stability that suits inland lakes, flat water and the intercoastal, with enough capability to reach bigger water on a calm day. The center console layout keeps the deck clear and easy to move around, and the boat carries a capacity of six passengers. Some configurations use Bayliner's M-shaped hull, which makes turning more stable. Buyers shopping the Bayliner T18 bay boat for sale will find it positioned as a value-focused first fishing boat or a step up from a smaller rig.
Power comes from a Mercury 115-horsepower four-stroke EFI outboard with power trim as the standard engine, backed by a 3-year factory warranty; a Mercury 90 is also fitted on some boats. The 30-gallon fuel tank supports day trips out of the bay. Steering is a tilt stainless wheel with a hydraulic system, and the boat rides on a Caravan galvanized bunk trailer measuring 21 feet 10 inches, equipped with a swing tongue, surge disc brakes, swivel jack, composite fenders with steps and 14-inch wheels.
The console holds analog gauges for speedometer, tachometer, fuel, voltmeter and trim, plus lighted helm switches, a 12-volt power outlet, a bilge pump, an electric horn and navigation and anchor lights. There is open space above the gauges to mount a graph, and boats have been rigged with a 7-inch Simrad display for sonar, side scan and instrumentation. An AM/FM Bluetooth stereo with Jensen Marine speakers is standard, with a waterproof stereo and AUX/USB input available through the convenience package. Stainless handrails and under-console storage round out the helm area.
Fishing and deck features define the layout. The bow has a casting platform with three storage compartments and a battery tray with rigging channels under the forward storage, ready for a 24-volt trolling motor on the included trolling motor bracket with plug. A forward console live well comes with the convenience package, and the stern carries a large aerated live well on a rear casting platform plus a transom live well. Rod stowage is extensive: rod holders on the sides and back of the console, six holders split three per side, a helm bench with three holders and a fold-down footrest, cockpit port and starboard rod racks, and rocket launcher holders. Two flip-up jump seats in the stern fold down for a walk-around casting deck or flip up to seat extra guests, with storage underneath.
Options worth weighing when buying include the hard T-top upgrade package, the stainless steel upgrade package, the convenience package, the trolling motor bracket and an automatic bilge pump; a bimini frame provides shade where the hard top isn't fitted. Fiberglass no-slip flooring runs throughout, and a four-step telescoping boarding ladder eases swimming and reboarding. The boat carries a limited lifetime hull and deck warranty and a one-year bow-to-stern warranty. Shoppers comparing Bayliner T18 bay boat prices, accessories and parts can confirm engine choice, trailer spec and which option packages are installed with a Bayliner T18 bay boat dealer before purchase.
