Small boats may be made of fiberglass, aluminum, or wood. While each has it's own benefit, none should be made to withstand being dragged along the sand or pulled up on a pebble beach. Move it to the beach on a trailer or dolly, or get help to carry it there.
The boat should be in the water before getting in. If you have to get in on land, take care not to overstress the hull by putting all of your weight in one spot.
When landing at a dock, fend the boat off and avoid bumping into things. If the boat cannot be put ashore overnight, secure it with bow and stern lines. Learn to tie and use a round turn and two half-hitches. Poorly tied mooring knots are the cause of much unnecessary damage to boats.
Do not leave a boat partially in the water at a shore. Wave action can cause the boat to rock up and down on the shore, leading to damage.
Wooden boats (or boats with wooden parts) need to be covered and ventilated, or will require refinishing every year. Varnish will not withstand even one season of sun unprotected. Whether wood or fiberglass, keep the boat dry and in the shade when possible, or use a cover to keep the finish in good condition.
Buoyancy tanks must be tested for leaks once a year. Regularly remove drain plugs to drain water from inside your boat. Make sure your boat is dry inside for the winter! Water in the tanks can be heard by tilting the boat.
Inflatable buoyancy bags should be tested for leaks once a year. Both buoyancy foam and bags should be properly fastened inside the boat.
Do not leave a sailboat with the sails up. The boat could blow over. When sailed are lowered, secure them with sheets to prevent them from blowing overboard.
