I'm interested in purchasing a 470 dinghy and although I've sailed a
bit, I'm not sure whether this type of boat is what I'm looking for.
Can anybody tell me anything or point to a website about this type of
sailing boat?

I know it is a racing boat but do you need a crew to sail it or can
you sail it (comfortably) by one person? Can you sail it slow or is it
always fast?

Thanks in advance
Darren.
