[Eustace the Monk]

Yes, you can solo them, but stick to the Phantoms. Best way is to zoom out your compass all the way. When the entire ship is within the compass by 2 widths, it is within broadside range. Fire L, turn while stationary, fire right, raise sails and distance again, repeat. It is more difficult to take down frigates this way (Front guns), but it is still possible.

As mentioned, you merely need to be on someone's ship and hit one with a single cannon shot to get credit for the sink, and possibly your wood. So try to crew up with someone who is sailing out of Padres and chances are that you will be sinking some undead vessels. Happy sailing.
