Due to the mode of capsize that we experienced, the impact with the water that Black Cat had to withstand was mostly with the roof and starboard side of the cabin, the remainder being with the starboard side decks and foredeck. Scantling rules use varying pressures for different parts of the boat, the highest pressures being in the bottom panels forward of the mast and reducing further aft and/or higher on the hull. Decks, cockpits and cabin fronts are lower pressures than the hull and the lowest pressures are for the top, sides and aft end of the cabin. This is a logical arrangement, yet there we were, falling multiple stories and cabin-first to make a big impact with the sloping face toward the bottom of the wave. Inspection of the structure showed only minimal damage in the form of a single fine vertical hairline crack in the mast bulkhead and attached roof beam above the door opening, which will be easily repaired.
In retrospect, there is only one term that comes to mind to properly describe what happened to Black Cat. Nature sent a big wave that performed a slam-dunk. She was picked up, turned over, slammed down and dunked. For us inside the boat it was all noise and upside-downness. My crew and I know that we came off lightly. Considering what happened to us, it could have been considerably worse.
