Unlike Scott, I found on Rhapsody it was easier to work from the inside when replacing core. I was able to work on my hands and knees, and gravity was my friend when bonding new core to the outer skin. I skipped the section under the ice box, but could have done that from underneath. I did do the center section behind the keel (and for about 12 inches forward of the trailing edge) from underneath the boat.
