Sailing Vacations

Thursday, January 31st, 2008

Sailing vacations provide great getaways for families in the open seas with nothing except the blue sky and the shimmering water. These vacations are conducted on boats, yachts, catamarans or trimarans and may last up to a week. People can go sailing either with their families or friends or with a whole group of other similar sailing vacationers.

Planning for a sailing vacation involves the selection of a suitable destination. Ideal destinations are those which have scenic beaches which can provide a grand view from the sea. Destinations should be selected with care because different destinations have different climates and ocean currents according to seasons.

Sailing - the Physics Simplified

Saturday, January 19th, 2008

There’s a little more to the physics of sailing than the wind just pushing the boat along. Sailing boats move forward because of the flow of wind over the sails and the action of water resistance on the hull. Quite often sailing boats will actually travel faster than the wind.

The movement of the wind and the motion of the boat combine to create an air flow known as the ‘apparent wind’. The curved surface of a filled sail causes this air flow to move faster over the leading surface of the sail than the other side creating lift much like an aeroplane wing. The resistance of the water on the hull and keel prevents the boat being pushed sideways and so the boat moves forwards.
