Annual firework extravaganza over Oulton Broad tonight and inevitably there were a few boats out there displaying anchor lights. Never put much thought to it before but what real use are they? A single light is of little value, is it a forty five footer lying abeam to you or a twelve foot wide boat pointing directly towards you? Then just how far away is it? The Broads is not the open sea, it's the Broads. The speed limit is six miles per hour, stick to that, or under, & you'll be able to see all that you need to see.
