So with three reefs in the main and I would assume a storm jib or partially furled genoa there would be minimal water bagged to prevent the boat righting itself when it was ready. But what would have happened if a strong gust knocked down a sloop with a fully hoisted main and a 150 Genoa let out with a thousand gallons of sea water now bagged in the sails? What would be my next step to help right the boat after ensuring the crew was safe? It's all hypothetical but I'm sure it's happened to someone out there.
Blow the sheets.
