The world‘s finest diving

SpoilsportExt1 opt786

Spoil Sport is a custom designed diving vessel accomodating up to 29 guests. At 30-meters (100-feet) she has a twin hull design, with maximized stability and comfort.

A word from Dom :  “I’ve known & worked with the Mike Ball operation for well over 20 years … and it is popular, in part, due to the variety of options offered – from 3 day to 7-day dive cruises to some of Australia’s best-known dive sites.  In addition, Spoil Sport offers some extraordinary & unique (sometimes exploratory) expeditions, which I highly recommend. “….. Dominick Macan

Spoil Sport “spoils” you with a 12 person crew, comfy cabins – many of which have ocean views – and a variety of itineraries taking you to the most popular Australian dive sites and some of the most remote & exotic.  She has a super-sized sundeck with optional shade cover equipped with chairs and loungers.  There is additional outdoor seating at the back of the upper deck which is largely is devoted to common living areas: a massive dining room, lounge area and bar.   Below that, on the main deck of the catamaran, you’ll find all the cabins … plus a super-sized dive deck and excellent facilities for photographers.  

You’ll enjoy chef-prepared meals and in-between meal snacks plus complimentary soft drinks and Australian wines served with dinner.

Itineraries normally include Ribbon Reefs and the Coral Sea, but at specific times in the year, there are special trips, such as the Minke whales in June & July, the Yongala wreck in November and a Shark Research trip in November/December.
