Waveset/Dynamic Env Maps question

I've been playing around with wavesets (which are awesome btw
). I have a question, however - how do I go about making the reflections look right when the age I'm making is surrounded by an ocean? The age is an artificially built complex surrounded by ocean, with hills on one side (these are billboarded) and just the horizon on the other. The centre of my waveset object falls right in the middle of the island. How do I get it to reflect the island and skydome correctly? I've played around and have yet to come up with a good result.
Thanks
