Re: 1979 Imperial
Also, just for what's it worth, you could cut some access holes in the deck (before your additional glass work) and just drop in some pour foam. I don't think that stuff is too heavy (I think Frisco has the weight specs on his thread), and would certainly give you some additional strength, floatation and noise reduction.
You could put back in the wooden plugs, and then glass over them.
Also, for inspiration and ideas you may want to check out this thread:

Mike did an absolutely masterful job on his center console... Granted, his was not a conversion, but they way he finished off his deck and some of the other finishing touches could be some real nice "adds" to your boat.
Also, I know you didn't ask for votes on this, but I'd also vote in favor of keeping the yellow. That type of "character" is why we love old boats and is part of her identity/character. Plus, you could save yourself a bunch of time and money given that the gel is in fantastic shape. That said, I would also see softening it a bit, by doing a some keel repair and new white paint on the bottom with the yellow on the sides.
Plus, in keeping it yellow, you'd have no trouble finding your boat at the dock!!!
Have a good one and keep posting. Can't wait to see this one unfold.
thanks,
