Hi,
If you're in the US you should find what you're looking for here

This is the US IOM forum with boats for sale.
The class rules allow for 3 rigs but to be honest once you have the top and mid rig you're sorted for 98% of wind conditions.
For the electrics most of us use the RMG winch

Hope this helps
You can check our IOM class website for all information related to the class.
