2025 SeaArk Shadow 18T

The SeaArk Shadow 18T is an 18-foot aluminum flats boat built for serious fishing. Constructed from .100 gauge marine-grade aluminum, the hull features a .125 gauge tread plate floor to prevent popping or oil canning, oversized extruded caprails that reinforce the top structure, and a 3/16" extruded center keel. These materials and construction methods combine to create a durable, low-maintenance platform.

Powered by a single 115 hp Yamaha engine, the Shadow 18T is sized to reach shallow water and get anglers where they need to be without excess weight or unnecessary systems. The straightforward design prioritizes functionality and simplicity, keeping maintenance manageable while keeping the boat ready for extended time on the water.
