The top 3 (and about 10 minutes to finish) as I can see it is 1 Gunnar larsen M20 2 Mitch Booth Hobie Tiger F18 3 John Moret Tornado. They are all 3 close together and it looks like Booth is overtaking Larsen. The leg to the finish is something lower than an upwind beat and a little higher than a reach. The make an arch away from the wind so the leg becomes increasingly more like a reach. This may very well help Booth in getting some extra speed.

But we'll only know when they finish.
