Tartan 455



In the weather, out of the weather. Now it’s your choice.

At Tartan our product development goals start with listening: to owners, to our dealers, and to our own hearts and minds. The new Tartan 455 deckhouse sloop is a design for the future of sailing created from the thoughts and ideas of present day owners who’ve sailed hundreds of thousands of miles. Tartan is re-defining performance cruising … again.



At Tartan Yachts we have a passion to deliver the best sailboat owner experience possible. Our commitment to design and engineering is based on total performance. We don’t believe that a simple superficial appeal to aesthetics is enough to serve the interests of our owners. Our designers, builders and sales team understand and appreciate that every yacht we build must be the best yacht we build. Most importantly we are committed to the next 50 years with the focus of simply making our customer experience the best the industry has to offer.

Designer’s Notes

T455 Designer’s Notes

At Tartan Yachts, we have been conceptualizing several different sizes of deckhouse sloops. The defining features are a large, twin-wheel working cockpit area, a crew/guest cockpit with easy access into a light and airy deck house, and a full inside steering station within the deckhouse. Working with a Cleveland area Tartan 3700 owner, we are excited to announce the launch of the Tartan 455 Deckhouse Sloop.

The 455 offers innovative performance cruising under sail or power. For wind and water in the face sailing, choose the aft cockpit, twin-wheel helm position with convenient sail controls led to large coaming mounted winches. The twin wheel arrangement also provides great centerline access to the large, hinge-down swim platform. The forward cockpit area is deep and well protected for crew and guests and offers an easy 6-inch step down into the deck house. Inside the deckhouse the 360-degree expanse of windows provides exceptional light and visibility. Overhead light and ventilation is provided by two sliding deck hatches over the helm to starboard and navigation area to port. Aft to port is a large U-shaped settee with a drop-leaf table, and to starboard is a well-appointed galley with a drawer-style refrigeration unit and countertop drop- in freezer. At the forward end of the deckhouse, a full inside steering station complete with a Llebroc ultraleather captain’s chair, wheel, navigation instruments, and engine controls results in extremely comfortable inside piloting when the weather is too hot, too cold or just plain too nasty to want to hunker down in the aft cockpit. To port a Llebroc ultraleather, extra wide captain’s chair with a work station/navigation station provides additional comfortable underway seating.

The cabin interior living spaces are a short three steps down from the deckhouse. Available as a two- or three-cabin layout, both with two heads. The owner’s cabin is forward with a large island queen-sized berth and private head with full stall shower and plenty of storage in Tartan’s hallmark solid stock cabinetry. All cabins are well ventilated by a large array of opening portlights and deck hatches. Additional light is provided by fixed hull portlights. The Tartan 455 sports a large, carbon-fiber, double-spreader mast by sister company, AMP Spars, with a self-tacking jib as the standard configuration. By adding a furling masthead light-air reacher, which creates Tartan’s exclusive CCR sail plan, the 455 puts great sailing performance, at your fingertips. With sail controls led aft to both cockpit helm positions, the sail tweaker in all of us will be satisfied. The 455’s steering pedestals are a work of art. Crafted in carbon-fiber they are strong, elegant and light weight.

Coupled to an efficient rudder with a carbon-fiber rudderpost, steering is light yet positive. A number of keel configurations will meet each owner’s requirements for their sailing locale.

The deckhouse roof not only serves as the anchor point for the mainsheet keeping the sheet safely out of the cockpits, a large recessed panel in the deckhouse exterior surface can be fitted with either Lexan panels for a dramatic skylight or, for those looking for an aesthetically pleasing solar installation, the recesses are sized for flush-mounted solar panels. Wide side decks and plenty of handholds along the top of the deckhouse, the lifelines, deck rails and extended bow and stern rails make movement on deck safe and secure. The 455 can be fitted with Tartan’s classic teak toe rails or for those who prefer less maintenance, anodized aluminum toe rails are available.

Innovation is one of the keys to Tartan Yachts’ long-term success. Moving forward with our first deckhouse design Tartan will lead the way to more comfortable yet exhilarating performance cruising. The first of her kind, the Tartan 455 Deckhouse Sloop will provide her owners’ unparalleled comfort, top-level pace, and breathtaking views while cruising, whether under sail or power.
