Richard,
I am a mechanical engineering student at soton uni and my aim is to eventually get into powerboat/rib design because I have a huge amount of interest in it. This forum is therefore great for me, because as well as helpful like minded people such as yourself, there also seems to be quite a few people involved in rib design and manufacture on here.
I have indeed considered companies around where I live but at the moment i'm sponsored by AMS in Cowes on the Isle of Wight who design and build Radars. Not exactly what I want to do but its all experience and of course money. I have to work for them every summer while I'm at uni which means I can't be out in my rib!
Any ideas on fitting tubes?!
Cheers
Tim
