Cobia 280 DC

The family offshore boat, solved.

The 280 DC is what happens when a serious offshore builder designs a family boat: twin Yamahas, a hull that's genuinely happy in the ocean, and a layout with bow seating, a real head, and enough storage for a beach day that turns into a fishing day. It's the biggest dual console Cobia builds on the classic hull, and it's a Delmarva natural.

We're the dealer Cobia has scored #1 in customer satisfaction for the whole brand — twice. A 280 DC from RT 113 gets rigged, sea-trialed and delivered by our own crew, and our Yamaha Pro Elite shop keeps it running for as long as you own it.

How big is the Cobia 280 DC?

28 ft overall with a 9 ft 06 in beam.

What is the deadrise on the Cobia 280 DC?

21 deg at the transom. A sharper V softens a chop; a flatter one adds stability at rest and shallower draft — where this one sits is part of what a sea trial is for.

What power does the Cobia 280 DC take?

Rated up to 600 hp. RT 113 rigs and water-tests every boat with Yamaha outboards — we are a Yamaha Marine Service Pro Elite dealer.

How much fuel does the Cobia 280 DC carry?

172 gal.
