so you are saying to drop the foresail and bring the main sail center and put the rudder what way?
also, if you have a sea anchor, why wouldnt you just drop all sails, deploy the sea anchor with plenty of rode, batten the hatches and just go to sleep?
why heave to when you have a sea anchor? seems like over kill.
Well, for one, the sea anchor is not easy to deploy and retrieve, but most of all, with a sea anchor you will drift downwind while heaving to will let you make some headway.
Also, it is extremely easy to get going again in seconds when done heaving to.
Deploying a sea anchor also requires going forward for a good deal of time, which would not be my favorite in stormy conditions, while heaving to is done in seconds from the cockpit.
Just my thoughts... Of course every boat, wind and sea condition will be different, as well as distance from shore.
