Atlantic 43

Classic elegance meets modern comfort in a timeless motor cruiser.

Project Details

The Atlantic 43 is a refined alternative to today's production boats, purpose-built for efficiency and lower-speed cruising. A single diesel engine and modern semi-displacement hull, combined with lightweight engineered structures, work together to maximize range, payload, and stability.
Below deck, the thoughtfully arranged interior balances comfort and practicality, designed primarily for the cruising couple with occasional guests in mind. The layout centers on a spacious pilothouse and dining lounge, with an optional plan that replaces the saloon with a private aft owner's stateroom.
Built to the highest standards on a semi-custom basis, the Atlantic 43 is a yacht that seamlessly blends timeless style, modern performance, and considered craftsmanship.

Length: 43’ (13m)
Type: Bridge Deck Cruiser

"Greg Siewert’s Atlantic (43) is cause for a sigh of relief. He got it right in a design that is honest, simple, and dedicated to the purpose of cruising two adults in comfort."
