Adding a little more info regarding the posts over the past couple of days, the "Tale of the Turtles" as well as the stone yard visit... The picture above is the area under the flooring for the VIP head. This head, the master head, and the galley, all have their floors heated with a circuit that is part of the diesel furnace heat.
So toasty warm floors. It's a bit of a luxury, but for those of us living in the PNW with stone floors, we know how special it is to have them heated. Hampton does a lot of these "little things" right.
