By 1200 (the knockdown was at 0200) the wind was down to 35 kts and we were able to set a storm jib, a reefed main and the mizzen. (I believe that we did not lose the rig because we had re-rigged in New Zealand with galvanized rigging three sizes larger than what was on there as it was the only wire available at the time)
With that rig we sailed into New York harbor and after cleaning up the engine, I was able to get it started (the engine was an 18 hp Albin diesel that I could hand crank) to get through Hells gate and around to City Island.
