Tom Hug of MR Power for the Detroits, if he still doing engine surveys. Outstanding, very articulate, and a good teacher too.
I would also recommend consulting Peter Hartoft of the eponymous firm in Annapolis for the hull survey, his late partner Gale Browning did my Hatteras for me along with Tom and was also outstanding, Peter too has a great reputation.
Last number for Tom I have is 410-274-7636
