ALTAIR | Oyster 475 | 48ft


Portsmouth, RI, US


The Oyster 475 is the culmination of knowledge and insight gained from successful designs that preceded it, like the Holman and Pye Oyster 485, the Humphreys Oyster 49, Oyster 53, and Oyster 46.

The Oyster 475 is a remarkable yacht. Most notable is its sheer amount of space, volume and storage. The cockpit is comfortable and protected with excellent 360-degree visibility, side decks are easy to travel, and there are great lounging spaces for sunny days. On deck there is a huge lazarette requiring steps for access. Below decks there are properly-sized hanging lockers and drawer storage in cabins, a large galley pantry, and plenty of room for spares and provisions under seating. Machinery and systems are easily accessible and well-thought-out. The fit and finish of the interior teak joinery is First Class.

ALTAIR was conceived by an experienced cruising couple seeking an offshore performance sailing platform that was easy to handle, safe, comfortable, swift and good looking.

After taking delivery, the owners could not have been happier with the sailing and handling characteristics of the Design. During their trip with the Oyster World Rally and ARC, they often beat larger models to the next destination. They discovered that managing maintenance on the Oyster 475 was much easier than on a larger boat, and their ability to take care of the boat as a couple without the help of crew engendered a more intimate ownership experience.

The Oyster 475 fills a real sweet spot for a yacht that is not only world-cruising capable, but equally easy to escape for a weekend on.

ALTAIR is one of the most highly specified Oyster 475’s built. The equipment list and spares inventory are more than worthy of another Oyster World Rally, Caribbean sabbatical or summer cruise. Please have a look at the full specifications, and contact us for an inspection or live video walk-through.

ALTAIR is fully equipped and ready to leave tomorrow to sail around the world, the Caribbean for the winter or to explore locally for the weekend. Having just completed the 2017-2019 Oyster World Rally, she is a proven sailing yacht. ALTAIR is steadfast in high winds and the most challenging sea states. The range with both fuel and water capacity is fantastic.

The Oyster 475 is just the right size for handling offshore adventures or getting into those small lovely anchorages. Having the same features of the larger yachts, ALTAIR is still easily handled by a couple. During the Oyster World Rally we were able to keep pace with the larger yachts, much to their chagrin.

We have found the in-boom furling system to be a great benefit, allowing us to run the full batten mainsail. It has proven to be far superior to the in-mast system. The cutter rig and deck plan offer a wide variety of sailing options.

The equipment on board enables us to be self-sustaining in the most remote locations, with a water maker, washer/dryer, and the spacious refrigerator and freezer. The amount of available storage in the lazarette, deck boxes and interior is incredible.

The isolation transformer with soft start allows us to plug in anywhere in the world. And the HVAC heat and air conditioning make ALTAIR a very comfortable home. 

ALTAIR is the perfect yacht for a family or couple. Whether your dream is a weekend trip, an afternoon sail with friends or the adventure of a lifetime, the ease of running this yacht will make it enjoyable. She has exceeded our expectations.
