Sadly, what I would have considered the obvious choice, the Super Petrel suffered an unexplained hull loss today. I've had a look at a few examples of the aircraft and have been very impressed at what I could see of the workmanship. Pricing too is attractive at around $115,000 for a basic VFR fitout. Obviously I'd be looking closely at the reasons for the crash and I suppose there could be issues with local support from hereon forward - damn a real shame!
The Seamax certainly looks the goods, but from the prices I've seen quoted, they are in a different market segment really. The Searey is well proven, but a little agricultural in comparison to the other two, not a criticism, merely an observation. I haven't checked out the numbers but per my uncalibrated mark one eyeball it cruises rather slower too.
Keep us posted, I am heading in a different direction for the present but something along these lines is very much on the radar for a little later on.
