The Physics of Sailing. Ashley Conklin. Basic Parts of a Sailboat. Mainsail- catches wind Jib- helps with turning the boat and also catches some wind Mast- holds up sail Boom- keeps mainsail stationary and helps to keep constant sail trim Rudder- provides a way to steer the boat
The Physics of Sailing
Sit on the opposite side of the sail with your body facing the sail and your eyes focused on the water in front of the boat.
Select a point in the distance and constantly aim for it using the rudder.
Pull in your sail so that it is catching the most amount of wind as it can.
Have your crew pull in the jib in the same manner.
Watch for other boats and obstacles
Tacking (turning the boat through “irons” or through the wind)
Make sure you have enough velocity
Point tiller away from sail- but not so far as to be flat against the back of the boat
Pull in sail and switch to opposite side of boat
If necessary, shift weight to the leeward side of the boat and backwind jib
Jibing (turning the boat through downwind point of sail)
Point tiller toward the sail
Pull in sail or hold onto boom to control boat speed and weight management
Let sail back out once it switches sides
Sailing upwind is a bit more difficult because you will move backwards if you point your boat into the wind
To sail to a point upwind, you must point your boat as close as it will go upwind and tack back and forth until you reach your destination
Sailing downwind is not as difficult as sailing upwind, but it is slightly different than other points of sail.
Mainsail can go on either side
Pay attention to steering so that you do not jibe accidentally
Spinnaker can be flown
