Cobia 285 Open

The tournament-lean 28.

The 285 Open strips the 285 concept toward the fishing side: more open cockpit, more rod storage, a leaner console — a boat set up to leave the inlet early and come back late. If your weekends are white marlin and sea bass more than sandbars, this is the 28-footer Cobia builds for you.

Buy it from the shop that wins Cobia's customer satisfaction crown: #1 CSI for the brand in 2024 and 2026, top-five dealer nationally. Rigged here, serviced here, walkthrough on our YouTube channel before you ever drive down.

How much fuel does the Cobia 285 Open carry?

231 gal.
