Anchored or Adrift?
It’s pretty costly to make a boat of any size. Whatever size, they all need a solid anchor to guard against drift that usually leads to shipwreck. Yes, the rudder and keel are vital, but those are both integral to the ship whereas the anchor’s role is to secure the vessel to something independently stronger, the mass of the sea bed. Lying off the many coasts around the world are sunken shipwrecks, many being preventable if there had but been a secure anchor in a storm.
