the link to the zodiac website on this here ribnet shows some cool stuff like a video for the medline 111, mouthwatering, and if the pocket was big enough.......
http://www.zodiac.fr/uk/ and also there is some news of a larger model to the pro range, a pro 20 man, looking smooth!!!!!!!!!! but cant think why an 8.5 metre boat would only achieve 'c' rating, surely as its designed for rougher seas than the smaller models, new hull shape, it would reach 'B' category? have a look!
