Wind Parallel to Pier • Set fenders

• Luff sails on final tack

• Coast to stop– At desired place– Good Luck on timing

• Set bow line first– Wind can blow you back

• Watch boom

– Hard to stop sailboat• Head into wind

– Have person on bow with boat hook• Will also signal directions

• Under sail approach using only jib• Drop headsail to stop
