Cored construction and foam floatation are two different things.
The way a Whaler is built (and some other manufacturers now-a-days) could
be considered a extreme meld of both I suppose. There have been cases of
Whalers becoming "waterlogged" due to cracks in the hull leading to water
saturation of the foam.

I agree with Harry regarding cored construction. Solid below and just up
over the waterline, then non-balsa coring (closed cell) is ok above.

Me too. What I meant to say is that if you go with a "non-sinkable"
hull like the CS or Whaler you are getting a cored hull.
Carolina Skiffs are also prone to waterlogging through cracks/poorly
sealed deck fittings.
A Mac 26 X/M has solid FRP hull, and the flotation is foam blocks in
various voids.
