put simply........

at or near the bottom of the daggerboard and rudder
is a horizontal foil, amking the assembly shaped like
a T.

In section these T-pieces look like an aeroplane
wing. They are about three feet wide or so.

The wing going through the water generates lift in
the same way that an aeroplane wing generates lift.
(low pressure over the curved surface above and
higher pressure below the flat surface below - pay
attention in physics lessons)

Hence the boat rises up when going fast enough.

Suddenly the wetted surface area is reduced by a
huge amount, and you therefore accelerate faster
and to a greater speed.

sort of....

i think...

The image is ruined slightly by the helmet wearing guys- i suppose thats sensible in that boat though Has anyone acually been himt on the head in a dinghy? Apart from my brother who was knocked out of his boat by a laser boom in the back of the head as the guy dumped the sheet around the wing mark!!!!

Never having seen an N12 in the flesh, I have to ask, what do they compare to for speed in a big breeze - a Laser? I've heard they're slower than a 420 in a blow, which makes sense considering the yardstick and lack of a trap and spinnaker.
