6 Anchoring Techniques Common Techniques for Local Islands Single Bow Anchor Easier Requires Room to Swing Bow and Stern Anchor Will Hold Boat in Position Better for Small, Crowded Anchorages It is Best if All Boats Use the Same Technique in an Anchorage All Single Bow All Bow/Stern

7 Anchoring Hardware All Chain Hardware is Strongest but Heavy Combination Chain and Rode Most Common For Sailboats Chain > Boat Length Rode Length Sufficient for Anchoring Depth Length Markers

8 Single Bow Anchor Scope > 7:1 for Secure Overnight Allow Room to Swing For 30 ft Depth: 210 ft Rode/Chain If Wind and Swell are at Angles may have Rough Night Boat may be at angle to the swells

9 Bow Stern Anchoring Boat Held in Position Good in Crowded Anchorages Hold Boat Relative to Swell Scope > 7:1 for Secure Overnight Techniques for Setting Stern Anchor Bow First Then Back Down Stern First Deploy with Dinghy

12 Anchoring Techniques So What Can Go Wrong? Santa Cruz Island is Famous for Strong Down Canyon Winds at Night Most Anchorages are at the Base of Canyons For Single Bow Anchor A 90 or 180 deg Wind Shift May Cause Anchor to Drag or Reset For Bow Stern Anchor Stern Anchor May Drag with Heavy Load Insufficient Rode Lighter Anchor

13 Anchoring Techniques So What Can Go Wrong? Setting Stern Anchor Can Be Tricky Avoid Fowling Prop if Backing Down Use Dinghy or Kayak if Close to Shore Eel Grass Can Be Difficult to Penetrate Potential to Drag What if Anchor Will Not Release Try 90 or 180 deg Pull If All Else Fails Cut Rode and Tie Off with Buoy; Retrieve Later
