I think Surtees originally made Barcrusher boats - BC imported them from NZ until they had a falling out with Neil Surtees. Now Barcrusher make their own boats in Vic.
My opinion - they are a slightly better quality boat than Barcrusher, look good and they are pretty good for the coin, although a quinny or savage would cost much less (albeit a rougher ride). I recently sold my Savage 6.0...it was crappy and noisy until I pulled up the plywood/carpet floor, sika-bonded all the ribs and bonded/rivetted a new alu checker-plate floor with kill-tank. It was then rock-solid. If the cheaper brands did this they would sell much better.
There are better plate boats around (Stabicraft, Extreme or Aqualine) that I would rather spend money on but that's another story.
