The luff of the main sail gets fastened to this.
MAST
This is the location on a boat from where the skipper steers the boat.
HELM
Sailing upwind, or sailing to windward, this is the closest course to the wind that you can sail on the edge of the no-go zone.
CLOSE HAUL (BEATING)
The ship's wheel is an example of this simple machine.
WHEEL AND AXEL
This principle states that within the flow of a fluid, like a liquid or a gas, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure.
BERNOULLI'S PRINCIPLE OF LIFT
This is a hydrofoil that in essence steers the ship.
RUDDER
This is the forward end of the sailboat.
BOW
A 90° area that's too close to the wind to sail in effectively.
IN IRONS (NO-GO ZONE)
The steps on a boat are an example of this simple machine.
INCLINED PLANE
Terms such as buoyancy, density and displacement are used to describe this STEM concept.
FLOTATION
The foot of the mainsail gets fastened to this.
BOOM
This is the aft end of the sailboat.
STERN
The boat is sailing away from the wind, with the wind coming from behind the boat, but not directly behind.
The tiller is an example of this simple machine.
LEVER
The heating and cooling of the earth's land and sea masses on a daily basis are used to explain this STEM concept.
LAND AND SEA BREEZES
This is used to reposition the boom in order to adjust the angle of the main sail.
MAIN SHEET
This is the left side of the sailboat when looking forward.
PORT
The boat is sailing directly downwind, with the wind coming from behind.
RUN
The blocks used on a sailboat are an example of this simple machine.
PULLEY
Terms such as anemometer, knots, direction are used to describe this STEM concept.
WIND POWER
These are the lines used to adjust the trim of the different sails.
SHEETS
This is the right side of the sailboat when looking forward.
STARBOARD
The wind comes across the boat at a 90° angle, perpendicular to the wind direction.
BEAM REACH
A winch and a propeller are examples of this simple machine.
SCREW
Terms such as turbidity, salinity and temperature are used to describe this STEM concept.
