Meh...was away for three weeks...just got back. I would have snapped the Osprey up straight away had I seen it 2 weeks ago!! It looks perfect.
But to update...we've taken our RYA level 2 moterboat and loved it. I've narrowed down boat choice to Avon Ribcraft oe Osprey (damn). Happy to go for 5.85 - 6.5 metres with 150 - 175 hp (suzuki yamaha or honda) 4 stroke. Budget still the same circa £20K but really looking in earnest now.
Will let you know how we get on!
Thanks for all the advice and offers (and if you want to sell that Osprey on at same price give me a shout!).
