I'm no fan of BSS, partly because there was some campaigning for people to use it as a general standard outside inland waterways. From what i recall some terms actually compromise seaworthiness. My take was that they're aimed at use where danger of fire, risk of environmental pollution, or damage to property are seen as greater risks than sinking or engine failure. As illustrated by a sign I saw on one waterway prohibiting pumping bilges - presumably they expect you just to sink if taking on water..The Inland BSS doesn't even look at the condition of the Hull only, electrics, fuel and gas systems. Its just looking at the safe installation of systems.
