Bob,
Where abouts are you in D2? Do you have a club using the site now? You would have to register a club and part of doing that would intale making your site sanctioned under IMPBA. This then covers that site under the insurance we all pay for. That's the first step, secondly, you would have to get tyhe set up of the site done for a race. Items that would be required and bring along with them are clock, raft to float clock, retrieve boat (1 for sure, maybe 2), drivers stand (?) and then finding a date in the D2 schedule. That might be the hardest as D2 basically has a race almost every weekend unless you hold a race early or late in the season. I know this because we are trying to do this also.
Let me know if you need any other info.
Dave
