Twenty seconds is a fair amount of time, next time you'll swim faster..

But seriously it's tricky to right a turtle cat first you need to work off the stern to pull the nose up and get the sail back on the surface from there it's cake. Leverage is everything!!! However most of those righting pulls are just not designed for a turtle so you’ll either need to re-rig the thing on the fly or have another system. Most people give very little thought to this until it happens so they get stuck.
