My Cape Dory 28, Nikki, was once anchored in such conditions as I was getting under way. On one huge surge, a ⅜-inch stainless shackle virtually exploded, and a custom-made stainless plow anchor and all of the chain were lost. At that instant, I felt the boat lurch as if it had backed into a seawall. The platform strut, along with the forestay, absorbed the entire enormous shock load, sparing the platform and the foredeck any damage. The compression strut should be made of 316 stainless-steel heavy-wall tubing with metal plate fittings at each end to connect the platform's underside to the hull stem.
