The 506's interior is generously finished in cherry. Fit and finish are good, and the hardware, fixtures and fabrics appear first-class. Carver's 2000 models incorporate a new structural design in which wood is eliminated below the waterline. The laminate schedule is modernized, with multidirectional reinforcements and a vinylester skin coat for blister protection. A matrix of transverse frames and continuous longitudinal stringers is molded separately and bonded to the hull.
Bulkheads are marine plywood.
Welded aluminum beams support the marine plywood saloon sole, and fiberglass liners define the belowdecks accommodations. Access to the machinery compartment is through a hatch in the saloon that incorporates the saloon sole and the steps that lead to the afterdeck. It is a bit awkward to lift, but once the hatch is open, engineroom access is excellent. The machinery area extends the length of the saloon belowdecks, and systems, while scattered, are accessible. Standard equipment includes an isolation transformer and an inverter, which should please those who cruise areas with questionable shore power or who cruise with doors open in northern climes.
