We could call you Bruce too, to avoid confusion.
We live in Riverview(Lane Cove area) on the northside, but keep the boat at Brooklyn on the Hawkesbury.
Liked VI a lot, nice place.Got there initially (well, I`d been there years ago) on a cruise ship returning from Alaska, later took the Victoria ferry back to see more,the Gardens etc,and esp to see some TFers we previously met in Sydney.
I once looked at an IG32, gelcoat seemed to have been cleaned with hydrochloric acid. Didn`t buy it, but liked the layout a lot, it had twin Lehman 80s, which I think would be ideal, with the handling plus of twins. (Let`s not restart the single vs twins debate).
The IG build quality is good and solid. Hull will be 1" thick or so( it needs to be for the osmosis). Wiring should be good too. I think you are onto the issues. Let us know how it goes.
