2025 SeaArk Shadow 18
About This Yacht
The 2025 SeaArk Shadow 18 is an aluminum bay boat built for efficiency and durability. The hull is constructed from .100 gauge marine grade aluminum with a .125 gauge tread plate floor to prevent flexing or oil canning. Oversized extruded caprails reinforce the top, and a 3/16" extruded center keel runs along the bottom. A single 115 hp Mercury 4-stroke engine powers the boat with a stainless steel propeller.
The open layout includes three Millennium fishing seats, a fiberglass console, and a rear seat box. The bow features an anchor locker and an 18-gallon fuel tank. Two live wells—a 9.5-gallon option in the console and a 20-gallon rear deck unit—support live bait storage. A telescoping 3-step stainless steel ladder provides water access.
Standard equipment includes a full electrical package with 12-volt accessory plug, auto bilge pump, LED courtesy lighting, and bow tilt and trim switch. The boat comes with a trailer fitted with aluminum wheels, a swing-away tongue, and spare tire. Motor tote and tie-down straps are included.
