She was built by William Heard at Broadwater yachts in Ballina, NSW . Australia in 1985. She was built to commercial registration standards to carry passengers.

 She was used as a chartered yacht in Sydney for several years before being delivered to HK in 1995.  We have had her since 1999 and took her for a 3500 mile , 6 month family cruise through the Philippines and Malaysian waters in 2000.  Now she is our home in Hong Kong, and taken out a couple of times a month throughout the year and continuously maintained.


Seabiscuit IV was built to the same hull shape as ‘Passagemaker’ and the process of designing that optimized long range hull is fully described in the book ‘Voyaging under Power” by Robert Beebe.

Designed for optimum range at 7.5kts she achieves this at about 800rpm in flat water, and uses a little over 1L/mile.  Cruising range is conservatively 3500 miles.  To sail well needs 18-30kts of wind, but decks stay very dry and in all conditions she is easily handled by 2 people and not hard to single hand.
