On some boats, being anchored is akin to being on a swing. Back and forth the boat sails, taking up far more than its fair share of the harbor. A cure for this is often a Riding Sail hoisted up the backstay like this one from Banner Bay Marine. It has an added feature in that the corners are outlined with reflective tape, making the boat stand out at night in the anchorage.
Pricing starts at $230. For information call Banner Bay Marine at (201) 452-2834 or see www.bannerbaymarine.com
