If the wind is at least slightly offshore you may be able to take the anchor up the beach, leaving the boat afloat. This will depend on any tidal stream. Plan for what will happen if the tide turns while you are ashore.
If you choose a lee shore, either sail ashore under jib only and lift the boat ashore or anchor close offshore and ease the boat back into shallow water to make your landing. Again, beware of the tide. A change in the conditions may result in the boat swinging out of reach once you are ashore, so consider taking a stern line ashore. To depart, simply climb aboard, hoist the sails and haul off using the anchor, as long as you haven’t let the boat dry out. More information can be found in the Seamanship chapter.
The height of tide at any time can be estimated reasonably accurately using one of two rules. The idea is to estimate the amount that the tide has accumulated or fallen in each hour. The flow accelerates and decelerates so the amount of water accumulated each hour is different. Note that you should still leave a margin for error.
