I haven't seen one in the flesh, but have read about them in the CT magazines. They look quite good and are manufactured from alloy, so they should be light and corrosion resistant.
Knowing what I know about quintrex the company and their boats, they will be built to a price and mass produced. With their boats they have a fixed options list from the factory and thats it, then its up to individual dealers to decide if they will do the extra's for you.
Tried to buy 10-15 boats off them last year (4.5m - 5m) but needed them built to Level floatation regs for NSW (Not much work, just some extra floatation) and they weren't interested basically saying we don't need your business as we can't keep up with the orders we get now. We bought Blue fins instead.
