I am certain Wouter is working on it right now! He's pretty good at that. Did I read that right? The Blade (.65) rates FASTER than the Reynolds 33 (.72) ?? How can that be?

We got to the beach around 7am, we scrambled to get the boat ready and the sails hoisted. We pushed off the beach with 15 minutes to start. Luckily everything was setup correctly. At the starting line, we did start within the fleet, pretty much dead smack in the middle. Seeing how I was being shadowed by such bigger boats and sails, I had to get out of there quick. We decided to foot our course. We bared off in pursuit of speed. It paid off tremendously. At about Turkey Point we had a lead on various boats that were in front of us at the starting line. Not having any local knowledge of the area, we were faced with a huge question/challenge; WHICH way to go around the small islands. Our course had set up on a collision path with an island and shallow water. We pulled our boards up and started pinching. We dropped speed and got stuck in a bad, NO WIND hole. At this point this is where all the boats we had a good lead on, passed right by us. A few errors on our behalf and a low wind situation equals a slow F16. This was our case. We were NOT going anywhere any time soon. Slowly all the other boats were zipping by. We did some minor changes on the boat and we started getting better speed. At this point it was too late in the race. We passed under card sound bridge and headed straight to the finish line.
Fun race plus awesome winds equals the sail of a lifetime. Those who missed this race missed an excellent opportunity to go out and see FL from a different perspective.
Since the race results do not show it, I would just like to point out that in the right conditions, a F16 can hold it's own with the Nacra 6.0 and Hobie 20. During the first 14.5 of 41 miles on a close reach with 14-17 knot winds, we were able to pass the Hobie 20 from behind and leeward being an eighth mile directly ahead at the Featherbank channel. Additionally, we were making ground from behind and leeward on the Nacra 6.0s getting within a hundred yards directly behind at the same channel. After that everyone went different routes with ours being the slowest.
Anyway, I was impressed that a 16 footer moved as well. Up to the channel, the GPS was showing speeds in the 12-13.5 knot range. At some point in the race the GPS recorded a max speed of 17 knots. It's not 20 knots, but with the wind conditions, I think it's pretty good.

If the race covers a distance of 41 miles (landmiles) then you were doing an average speed of 19 kph = 12 mph = 10 knots. Which is pretty high is you were caught in a windhole for some time.
On a F16 you should be able to continiously match the windspeed in boatspeed when the wind blows between 10 and 20 knots. With the right trim you can push it a just little further then that. Below 10 knots of wind the F16's can achieve 150 % boatspeed and higher with some normal trimming.
Sounds like you guys are getting into the groove. The best part is that there is even more performance to expect at this point.
Geert on his Blade F16 and myself on my Taipan F16 achieved some 18 knots boat speed in some 15 knots of wind last year; under spinnaker.
Best of winds at Ricks seminar !

Sorry, in one case I used statute miles and the other nautical miles. The distance to the Featherbed channel was 14.5 nautical miles of a 35 nautical mile race.
Pete, I truly believe we could have been 15 minutes faster if we had followed the Nacra 6.0 through Midnight Pass. It is one of those typical cases of could of / would of / should of, but didn't.
Wouter, I think you meant 19 kph instead of 19 mph.

Next year, I will be cutting right through that corner.
Now that I'm back on the computer, I can see why the H16s were able to avoid Featherbank channel. You can stay West of the channel by staying West of the adjoining bank, ie. waypoint 25 32.0 N, 80 15.9 W. Then stay East of Pelican Bank, ie. waypoint 25 26.9 N 80 16.85 W and head for Midnight Pass. You just need to ask if there is a favored side to Midnight Pass or if you just go down the middle. You can download the chart at:
Chart 11451 covers Biscayne Bay and you will need to download a a program (links on site) to read it. The Maptech software seems to work well. This stuff is not intended for navigation, but it appears to be quite good with the cursor giving the LAT/LON numbers. Much easier than using a divider on a physical chart.

Come to think of it. Those Nacra 6.0 NE spinnakers are by themselfs larger then all the sail area on your boat combined, Robi. This must account for at least SOME headway !
Would look pretty foolish otherwise.
