if any instructors would like my input on this, please feel free to drop me a pm. I currently dive, wakeboard, snow ski and are learning to ride an air chair at present. I have access to a lot of disability clubs/organisations including back-up, sia, british wheelchair sports federation, and many more (mostly through my previous job). I have also been involved with boats for about 14years, of which i have been in a chair for the last 12yrs. I also water ski'd with the gb team (although never quite got in) a while back. there is lots of interest from disabled people in these types of sports, which are becoming more accessible over time.
if anyone would like any info, i'd be happy to help........no charge either
