Generally it is best to stay anchored. PROVIDED there is adequate scope- and that means ALOT of scope- at least 7:1- 10:1.
If unable to anchor safely, next bet would be a sea anchor. If you must motor, it's best done downsea but that's VERY hairy...if power is lost the boat will turn sideways in the trough and it's all over.
Inadequate scope means the bow will be unable to rise as the waves pass under the bow. I watched a buddy boat years ago have to cut his anchor line during a storm because he didn't have enough scope aboard and his bow was beginning to ship the building seas.
Pure conjecture, but this may have contributed to the tragedy in this case. Water depths are around 120 ft or so in the area where the boat was found. The vessel would have needed over 800' of rode to anchor safely- few boats in the 21' range can carry that much...
We maybe should start a different thread discuss this.
I may be wrong so if I am please someone speak up.
Lets assume they did not have sea anchor.
From what I understand, given a high sea and dead motor, the thing you should do is deploy your bow anchor even if it never touches bottom. It will act as a sea anchor and will help keep you bow to the wind / waves. The bow gives you better protection then any other part of the boat.
If you can possibly secure a fender to the anchor to help it float it will work even better.
Again, please correct me if I’m wrong.
