My experience is that heaving to is:
- good in conditions that are not rough, for a break
- Often difficult, if not impossible, in today's boats/rough conditions.
-in rough seas can be quite dangerous. The
water is more powerful than your minimal reduced sail. The breaking waves cover the boat forcing the bow to the lee. The boat veers off and is essentialy lying ahull with each cycle in a big wave trough. While in the trough, there is no wind to
work the
sails.
-Then it repeats that.
-Even the Pardeys talk extensively about trying to use a
bridle to keep the boat oriented correctly.... and their boat is a true long keel as opposed to a cutaway keel , long fin etc.
-Water is stronger than wind.
