Just to add a bit of an update ... I used my Gumotex Twist (full Nitrilon version) a few times in Spain in December/January/February and it was great ... I like heading for the big waves and going round rocks etc as it adds to the fun. When in the 'troughs' the waves were up to 2ft higher and the kayak went over them without an issue - Tazzy also loved it ... that was until she got splashed from my paddle then she sulked big style ... she does NOT like being wet!
Is yours the single or tandem? Tempted ...
