49'er

Description

These data comes from a GPX kindly provided by Karen Scheider. He wrote about it:
"The 49er was sailed in about 10-18 knots by my friend Dennis Jones, as mentioned before he is a very accomplished sailor having sailed (and won) at international level numerous times including americas cup here in fremantle in 1987 with kookaburra.this file should be a very good representation of the 49er's abillity in expert hands. p.s the term '3 of a kind'refers to an annual regatta sailed here in perth it is a race between different classes such as 14 foot skiffs etc,dennis has won this outright for 4 years now."

Apparent wind analysis

I'm waiting for any specialist comments to include here...

Here again, I'm waiting for specialist comments. I just remark that apparent wind comes from front, as for windsurfing, since 49' generate a lot of speed and apparent wind.
