Combine the unique PopTop cabin design of O'Day's new flagship with proven race-winning performance, and you have the most exciting breakthrough boat since the inception of fiberglass sailboat construction.
O'Day achieved this best-of-both-worlds success by calling on the skills of two leading design firms: Andrew T. Kostanecki, Inc., a nationally known industrial designer and boating expert, designed the accommodations and engineered the expanding cabin concept (design patent pending), while C. Raymond Hunt Associates designed the hull and rig.
The combination of two specialist groups has resulted in a 23-footer approaching the comfort of many 30-footers, with the potential to out-sail many boats up to that size.

With the cabin top in the "down" position, headroom is 4' 7", and all facilities, including the four-place dinette, are easily used. With a few turns of a single winch, the cabin top raises to yield 6' 4" headroom and amazing comfort.
The lifting mechanism is adapted from a system built into thousands of camper trailers and, like the rest of the boat, is warranted for 2 full years. Cabin facilities include berths for five adults, a convertible dinette, a galley area, a hanging locker, and a head with either a standard marine toilet or a self-contained unit.
Secure stowage is provided beneath all bunks, the dinette, and the galley counter. The cabin area is molded as a one-piece section extending from the bow to the cockpit.

This adds strength to the hull and eliminates many seams and joints, making the 23's cabin easy to clean and maintain.
With an optional camper cabin curtain, the entire cabin area is screened, and with weather curtains zipped in place, it gives warm, dry protection from rain and dampness.
When the cabin is in the "down" position, a pressure-compacted gasket prevents leaks from entering through the overlapping deck and cabin junctions. Since the "23" can be transported on a car trailer, she can live aboard while on the road, too.

In the water and on the wind, Hunt Associates' design work comes into play. Her combination keel/centerboard gives excellent stability on all points of sail, while aiding windward performance with the board down, and reducing drag off-wind when it is raised.
The long, narrow keel weighs 1,250 lbs. and makes the O'Day 23 self-righting. It effectively reduces sideslip so that you can sail close-hauled with the board up in shoal-draft cruising areas — a nice safety feature as well.

Her wide beam adds comfort below, while her shallow draft bottom provides surfing performance downwind. The balanced spade-type rudder partially extends aft to the transom for maximum control and sensitive steering. Although not necessary, it can be removed for trailering.
The tall masthead rig affords generous sail area. When overlapping genoas are used, windward and reaching performance is startling. With the addition of a spinnaker, the 23 becomes the boat to beat in cruising class races.

In her first season of racing, the 23 has beaten a host of larger, more racing- oriented competitors: both boat-for-boat and on corrected time.
In the deep cockpit, which easily seats six and is self-bailing, you will find additional seat lockers for stowing your outboard engine and sails. A reinforced outboard mount is located on the transom. The cockpit floor, seat tops, and deck areas are molded with a non-skid pattern.
Undoubtedly, this is the most amazing boat ever built by O'Day, as we are sure you and your friends will agree.
