Stumbled across a Ribtec 5.5 with Honda 90... any use? Looks more leisure orientated with GRP A-frame, hydraulic steering, stainless steel prop, navigation lights, Garmin Plotter (2012), etc. you have mail.
have a look at this one, bit small than you were after but it's a great rib, been cosseted most of its life, I'm sure Jeff will haggle over the dosh, he likes a good haggle
