Cruiseship group Genting Hong Kong has forecast a bigger net loss in the first six months due to increased competition and shipyard costs.

The deficit will be between $200m and $220m, it warned, against a loss of $73.7m a year ago.

The figures exclude the result of Travellers International Hotel Group, which is separately listed.

The Malaysian company, listed in Hong Kong, blamed an operating loss for Crystal Cruises due to a more competitive environment.

This was due to a 13.7% increase in new luxury cruiseship capacity in the industry, higher marketing costs and start-up costs of new Crystal river ships and AirCruises operations.

The company also cited start-up losses for the German shipyards it took over in 2016, as they gear up for steel cutting on the Global Class and Endeavor Class ships in March next year.

In addition, there has been more depreciation and amortisation for a new ship called Genting Dream.

Despite this, the performance of the underlying core Asian cruise business has improved in the second quarter of 2017 compared to the first quarter, it said.

The group remains positive about this market for the rest of the year.
