we recently came into possession of this Newport 28 sail boat, 1981, and I cannot seem to find out if the mast is grounded. There is nothing about it in the factory manual, and there are no wires that we can obviously see that are grounding the mast. If the mast was grounded via the chain plates during factory build, we would not be able to tell without disassembling those. Not something we want to do. Does anyone know if this model/year was generally grounded during factory build? Or know of any way to find out without hauling the boat? We are in the middle of a trip down the icw from D.C. to Charleston, SC, and we have encountered many storms littered with lightening. Any advice or info would be much appreciated
