Interesting posts! I suspect Graham and the Scorpion crew don't defend, because they don't need to.
2 years ago I bought a 10 year old Scorpion, which exceeded all expectations. I live in the Channel Islands, and we get hit with the full fury of the Atlantic. I ran the boat for a full 2 seasons, including winter outings, and it never ever let me down (well the Optimax did, but that's another story ...). The rib itself is built with the most extraordinary attention to detail and build quality.
This year I treated myself to a new 8.5m. I put my old rib, Quick Exit, on the market and sold it in 3 days for £500 less than I bought it for. I've got zero criticisms of the new rib - the pacific rim seat at the stern, and superb build quality makes the boat really stand out (and it's yellow tubes help). The new rib lands better than the old one, it seems to have better weight distribution.
The experience of buying from Joyce (she's amazing!), and Graham's team was an absolute pleasure, and the after-sales service second to none.
I took the last rib through 30' F7 waves (witness to prove), and lived to tell the tale. There's nothing to beat it.
