I believe that it was during the winter of '76-77 that the John G Munson had crack arrestors installed. These were strips about 1 inch wide cut out of her spar deck, on both sides of the hatches. The cuts run pretty much the length of the deck and have plates (about 7/8 in thick X 12(?) inches wide) riveted down over the cuts. It took about a week of carefully loading stone to get the boat perfectly level, and about another week to make the cuts. Then came the process that seemed to be never ending - drilling thousands of holes in the deck to accept the rivets. All phases of the work were performed during "Winter Work" in the Frog Pond at Calcite, under the constant inspection of ABS and USGC.
