I anchor at the Southern CA Channel Islands all the time solo. Yes, you need a bow and stern anchor. I usually set and retrieve the stern anchor from the kayak. You need to do this in the morning before the wind comes up. Lengthen rode on the stern and pull yourself up to the chain on the bow anchor but don't break out the bow anchor. Cleat off and your boat will sit very motionless right over the bow anchor. Go get the stern anchor in your kayak. Get everything all stowed and ready to go. Light the engine, get the main ready to hoist. Then break out the bow anchor and carefully exit the cove. There will be boats all around.
