You lost any credibility when you mentioned purchasing used vessels to make money.
Used vessels can make money, in the specialty area, depends what your market is, the ship, and associated costs. We were not intending to use it as a ferry if that's what you thought, more along the lines of what it's actually become, but slightly different. So far all the Bass Straight ferries have been used ships, the Abel Tasman being around 10 years old when it started Tasmanian service in 85', the original Spirit of Tasmania was 8 years old, and the two Superfast ferries were 4 years old when they started the Bass Straight runs. The next two ships are purpose built and will be new, due to replace the two Superfasts next year.
As for Bonza, their flights look fullish, as always who knows what yields and such are occurring. If they could get most of those pax to repeat custom on higher fares they might just have a business.
