Posts: 3,969 | Not seeing how the offset would help. You'd still have the fleet crossing the course to finish from B, and worse, it's a one-way parade down the whole length of the course. B-F (at the starting boat) simply does not work for trapezoids.
Rick, most of the traps I've seen used are essentially inside-outside loops, with all boats finishing on the left side of the course somewhere (like John W's posted SIs). That is not what you want with Waves and spinnaker cats, so we have to think outside the box a bit.
I think you're basically there. There are going to be limitations, because your primary focus is to separate fleets for safety. Finishing the orange boats at their gate and the yellow boats at the starboard side of the signal boat is probably the best plan, because that will also allow you to have starts as fleets are finished (without waiting for everyone).
But of course, it's a balance. If you push to start the spin cats while waiting for the yellow boats to finish, you will have mixed boats on the same side of the course again...

Posts: 1,884 Detroit, MI | For the Havamega, which will have Hobie 17s, 18s and Waves on the Bravo course, I'm planning to use a course similar to what was used at the youth championships (that John posted), except that I'll have a separate finish line for the Waves set about 200 yds to leeward of the starting line. That way, the Waves will have their reaches and will be clear of the bigger boats. This is also presuming I'll have the number of Waves there to justify using 5 extra marks and at least 4 mark boats to manage the course. | | | Re: Possible 2010 Tradewinds Course

Posts: 3,969 | Just so everyone is talking about the same thing, here's John's trapezoid link (was in another post): http://www.abyc.org/upload/2009YouthWorldQualifierSIs.pdfI've seen a finish line set up at Mark 5 at some Opti and Laser events (including Olympic Trials). This works well when the boats are of somewhat comparable speed, you send the first fleet(s) around the "other loop" and the later ones around the "inner loop." They all finish at the Mark 5 finish line, and this keeps the starting line clear and ready. Not sure that this would work with spins and Waves, because I think eventually, the spinnakers are going to catch the Waves, but I suppose with some practice, we could get it to work. If I'm understanding Matt correctly, he plans to send the Waves off first, over to the "outer loop" and eventually down to a finish line at Mark 5. The 17s and 18s would stay on the "inner loop" and do standard W/L courses, finishing at the signal boat. Or, are you thinking of another arrangement Matt?

Posts: 1,884 Detroit, MI | That's basically it, Mike. If I've got enough playground, I'm going to try to give the Waves an upwind finish after they round Mark 5. The mark boat assigned to that part of the course would set a line a couple hundred yards upwind of Mark 5, but still far enough below the main S/F line so they wouldn't interefere with the 18 and 17 finishers. The Waves would go either S-1-2-3G-5-F or S-1-2-3G-2-3G-5-F, depending on the wind velocity. I can stage it so that everybody finishes about the same time. The only "dangerous crossing" is when the Waves are reaching to Mark 2, since they'll be crossing the port layline to the 17s weather mark (further to weather of Wave's Mark 1). Waves will be on stbd.; 17s on port. Could get interesting. BTW, these are the racing circles for the HAVAMEGA: Alpha Course: Tiger, H-20, FX-One Bravo Course H-18, H-17, Hobie Wave Charlie Course: H-14, H-16, H-16 TrapSeat, any other non-championship classes | | | Re: Possible 2010 Tradewinds Course

I can stage it so that everybody finishes about the same time. These courses are not going to make the Waves very happy.., way too much downwind sailing. The official course of IWCA is a triangle, windward and leeward finish. The reason is they all hate downwind sailing (very boring) and tacking downwind simply does not pay off. Thus, the official course offers two upwinds, two reaches and one downwind. I know the class is open to all kinds of ideas, as long as it doesn't make for MORE downwind legs.., less preferrably.

Your event in FL is the IWCA North Americans. It's kinda like the WBA and WBC in boxing. Maybe we'll come up with some kick-butt belts for the champs to wear . . . . . or not. | | | Re: Possible 2010 Tradewinds Course

The second one has 4 upwind legs, 2 reaches and 2 downwind legs. The Hobie 14 goes dead downwind, too - those legs are incredibly tactical (in a slow, painful death sort of way) as the fleet jockeys to maintain clear air from behind. | | |
