with the wires just a 1/4 drill hole through the vert support and cable tie it off. Photo is probably misleading but any unsecured wire will eventually either wear through or at the piont it keeps flexing will eventually fail - no bilge pump. With Auto ones people forget especially on moored boats that they are often wired direct to battery and when wires decay they put a stray current through the hull. Seen it a few times with mysterious paint failing and annodes dissolving and then one boat sinking.
I'm surprised you only have one bilge pump?
Don't get me started on airtight compartments
Terrible performance by Noble boats that this boat ever left the factory and their after sales is non existant.
