Antaeus has undergone extensive alterations and improvements including continually renewing sail wardrobes, two new rudders, and a full refit in 1997 which included the fitting of a one of a kind lifting keel allowing the draft to be reduced from 4 meters when racing, to 2.8 meters when cruising. The engineering of the keel is so efficient that it is able to be lifted and lowered while travelling at speeds of up to 10 knots. At 65 feet (20.2 meters) Antaeus is suitable for berthing in most marina facilities, while the lift keel allows access to most harbours and sheltered anchorages.

As well as being a world class racer, Antaeus is also a comfortable cruiser, boasting a moulded Rimu interior with leather upholstery, two staterooms, two bathrooms and accommodation for 10 whilst racing and 7 whilst cruising. Amenities include 3 showers, enviro-friendly Lectra-San toilet, 1200 litre a day water maker, 240 volt power, Freezer and fridge. Autopilot, electric winch and the removable roller furler headsail make her simple for two handed sailing (Antaeus has successfully competed in two handed events), while the cruising mainsail requires no operation of the running backstays. As well as the usual GPS and computer navigational equipment Antaeus also features a forward facing sonar with a range of 200 meters, which helps in the detection of reefs and other submerged objects that can be life threatening hazards whilst cruising coral islands and atolls.

Due to her multi use as both a competitive racer and comfortable cruiser, an extensive conversion routine has been developed to eliminate excess weight and free up interior space for storage. The displacement difference for cruising and racing is around 2 - 2.5 tonnes. Items that are removable for race purposes include, dining table, all upholstery squabs and mattresses, cabin doors, cutlery and crockery, tenders and outboards, stove, roller furler, dodgers, dive compressor and television. Antaeus also has the advantage of being able to carry minimal amounts of water due to the large water making capacity.

A powerful 112 horsepower Cummins diesel engine powers Antaeus to a cruising speed of about 8 knots and provides much assistance for berthing and tight manoeuvring. 80 meters of anchor chain is fed from a well in the middle of the boat up to deck level where it travels forward to the bow in a passage concealed under the deck. This keeps weight central for racing purposes, however for serious racing the anchor and chain are removed altogether.

Since 1995 Antaeus has been an evergreen competitor in inshore race series' in the Hauraki gulf such as the Air New Zealand IMS regatta and the Gold Cup Series, during the New Zealand summer, then raced offshore in winter, in the last 6 years competing in 4 Auckland to Fiji races, Bay of Islands to Port Vila, Vanuatu, and Auckland to Noumea, taking line honours on 5 of such occasions. Antaeus currently holds the race record for Auckland to Denarau, Fiji of 4 days 8 hours 54 mins (over 12kt average). On each occasion Antaeus has cruised extensively at the tropical destinations entertaining up to 11 guests at a time plus 1 crew and cook. Typically returning home via Australia, following the Hamilton and Hayman island race weeks.
