Spirit of Hervey Bay – MV Grant Dorn 2008 for Sale – 23.5m Fibreglass Whale Watching Catamaran, 244-Passenger Vessel, Queensland

The flagship vessel of the renowned Spirit of Hervey Bay whale watching operation, MV Grant Dorn, is now available for sale. Built in 2008 by Streamline Catamarans in Hervey Bay, this 23.5-metre fibreglass catamaran is the largest and most iconic whale watching vessel in the region. Licensed to carry 244 passengers in 1D waters and 100 passengers in 1C waters, she offers a powerful combination of capacity, performance, and proven commercial success, making her an exceptional opportunity for serious operators in the tourism and charter sector.


1. General Specifications

The MV Grant Dorn measures 23.50 metres in length with a beam of approximately 8.5 metres, providing excellent stability and deck volume. Her shallow draft of around 1.8 metres is ideal for coastal cruising in Queensland waters and accessing nearshore whale watching and tourism areas.

Constructed using high-quality fibreglass/GRP composite materials, she benefits from the strength, reduced weight, and low maintenance of composite construction. Delivered by respected Australian builder Streamline Catamarans, this twin-hull vessel has been designed specifically to maximise passenger comfort, visibility, and operational efficiency.


2. Performance & Engineering

MV Grant Dorn is powered by twin inboard diesel engines that deliver strong, reliable performance to support daily whale watching schedules. Her typical cruising speed is around 18 knots, with a top speed of approximately 22 knots, balancing swift transits with passenger comfort.

A 4,000-litre fuel tank capacity ensures excellent operational range and endurance, even during intensive peak seasons. Generator support provides reliable onboard electricity for lighting, refrigeration, entertainment, and passenger comfort systems. The catamaran hull form naturally enhances fuel efficiency per passenger compared with many monohull designs, contributing to lower running costs and more sustainable operations.


3. Interior & Exterior Features

Specifically configured for high-capacity passenger operations, MV Grant Dorn can accommodate up to 244 guests for day cruises. Her layout includes:

  • Multiple spacious viewing decks with a mix of shaded and open-air seating
  • Wide walkways and railings to ensure safe movement and clear vantage points
  • Unique underwater viewing windows in each hull, allowing guests to view marine life below the surface

Passenger amenities include modern toilet facilities, a functional galley for catering, and dedicated crew workstations. The stern and side decks provide ample space for guests to spread out and enjoy unobstructed views of whales and other marine life. The vessel also features a large swim platform, adding versatility for private charters or leisure cruises outside whale season.


4. Navigation & Technology

MV Grant Dorn is equipped with a professional-grade navigation and communications suite, including:

  • GPS and chart plotter
  • Radar
  • Sonar for depth and target awareness
  • Autopilot systems for efficient cruising
  • AIS for vessel tracking and collision avoidance
  • VHF communications for ship-to-ship and ship-to-shore contact

Her inherent catamaran stability, along with this advanced electronics package, ensures safe, smooth, and efficient navigation in a wide range of sea conditions, supporting both guest comfort and operational reliability.


5. Luxury & Comfort

Though primarily a commercial passenger vessel, MV Grant Dorn offers a generous level of guest comfort. Airy interiors with wide seating zones and large panoramic windows create a bright, open atmosphere. Natural light and airflow have been carefully considered in the design, contributing to a pleasant onboard environment.

One of the standout luxury-style features is the underwater viewing windows, giving passengers a unique opportunity to observe whales and other marine life beneath the surface — an experience very few vessels can offer. Audio systems and commentary setups are installed to deliver informative, engaging whale watching narration.


6. Usage Potential

The vessel’s primary role has been as a dedicated whale watching platform, but her versatility allows for many other uses, including:

  • Private charters and corporate functions
  • Dinner and sunset cruises
  • School excursions and educational trips
  • Coastal sightseeing tours
  • Seasonal event cruises

Her large capacity makes it possible to generate strong revenue over short peak seasons, while off-season operations can focus on coastal cruising or private charters. MV Grant Dorn can also be chartered to other operators as a replacement or supplementary vessel, increasing utilisation and income potential.


7. Maintenance & Upgrades

Meticulous maintenance has been a hallmark of MV Grant Dorn’s operation. Experienced skippers and crew have ensured regular servicing of engines, systems, and safety equipment. Antifouling and hull maintenance have been conducted at appropriate intervals, while survey requirements have been diligently met.

Onboard systems and passenger amenities have been upgraded when needed to meet evolving maritime and guest-experience standards. The vessel is presented in excellent condition, ready for immediate continuation of commercial service.


8. Registration & Legal Aspects

MV Grant Dorn is Australian-flagged and fully compliant with Maritime Safety Queensland regulations. She holds:

  • Certificate of Operation
  • Certificate of Survey
  • Safety Management System (SMS)
  • Commercial Activity Agreement (whale watch permit)

These documents and permits make her an outstanding turnkey acquisition for Australian buyers. Clear ownership history and long-standing family ownership since launch in 2008 further add to buyer confidence.

  • The vessel alone – with price negotiable
  • The complete whale watching business – including permits, forward bookings, website, social media, and associated assets, offered as a WIWO (Walk In, Walk Out) package at approximately AUD $2.5M

Insurance details

- KaterBlue ensures all boats are insured by their owners, but advise guests to secure Travel Insurance for off-boat incidents. While boat owners cover marine accidents, guests are responsible for their valuables, or entrust to the captain. In case of an accident, captains must inform KaterBlue promptly. Owners are liable for the lack of proper insurance. Guests engaging in water sports do so at their own risk and should have personal insurance.
