	To help you choose, I've just added the Young 11 polar to my blog. The First and the Class 40 were already listed. http://daysailer.wordpress.com/ -- Cheers, Philip

	To make my choice of boat easier, I copied each of the three polars into my Paint program, copied them all onto the same page, and then resized them accurately. By making each transparent,I could then overlay one polar on top of each of the others, to make a direct comparison of the expected performance. The Class 40 polars exceeded those of the other two boats by a significant margin. Unless a calculated handicap system is employed, the performance difference is so great that only the Class 40 boat should be chosen. I do not think this was the intention of the organizers. I just added a second horizontal line to show that the scales are actually the same --- Last Edited by Rod at 2011-05-15 00:01:30 --- If it breaks, it's not strong enough--if it doesn't, it's too heavy.

	(Spoiler) ORC handicap data in attached jpg. I'll try to run accurate handicapping for the race using our polars and weather for those interested. Also attached spec comparison for the three. --- Last Edited by 76Trombones at 2011-05-15 02:02:08 --- Attachments GPH.JPG (28.0 KB) Specs.JPG (34.7 KB)

	WOW... this really took a lot of the fun out of it but shows that SOTP is still reasonably good. All I did was look at the polars, eyeball the grib to see what the weather was likely to be and came up with the Class 40 as a good pick... no routers, or handicaps, etc. I'm sure everyone else did the same thing, only MUCH more sophisticated. Guess that's fun too. I'll stick with my original choice since I came to it through my own efforts.

	An early season tropical 'something' in the central Gulf could make this choice interesting?

	newsartist said @ 2011-05-15 00:53:17: An early season tropical 'something' in the central Gulf could make this choice interesting? No. Just by looking at the polar data (all 3 are available on my blog at the link above) you can tell the Class 40 outperforms the other two at any wind angle and wind speed. Mathias' idea to handicap the race would make it somewhat interesting. Still, I wouldn't put any money on a dark horse, here. Cheers, Philip Oh, BTW, the polar data can also be viewed here on the SOL site: Class40: http://tinyurl.com/6zeqw33 First: http://tinyurl.com/68x4vz3 Young: http://tinyurl.com/5vp3gyl --- Last Edited by Schakel at 2011-05-15 08:40:04 ---

	Just looking at the polar overlays this would appear to be an absolute 'no brainer' (please excuse the expression!!) with Class 40 well ahead on all points of sailing and in all wind strengths. But stranger things happen at sea - as they say. What however would be mighty interesting would be for each class to be colour coded (for this race only). This would give us an immediate picture on the race course - which could be quite exciting. Second thought - rather than have a complex handicap system (if the colour coding was used especially) why not just have three seperate class winners? Keeps it simple. Cheers Ketch

	Time permitting I will post rankings per boat type, similar to the rankings of last year's IMSYC race (see thread at http://tinyurl.com/6c5r5on), on my blog. That'll make it more of a "class" race. FYI, my blog is at http://tinyurl.com/2eu24vz HTH, HAND, Philip --- Last Edited by Schakel at 2011-05-15 10:37:40 ---

	If choosing the Class40 was that obvious (which I did not see, I just picked the middle one) I think a handicap-system is the most logical thing to compare these three wonderful (polar-uncomparable) boats... Just my thoughts, but who believes a catsailor when talking about monohulls? Arthur If you're still in control, you're not going fast enough.

	Is anyone working out the handicap results? As I am winning the 40.7, I might have a chance....

Melbourne to Osaka Prelude 2024

Welcome once again to what these days is Sailonline’s almost annual virtual Melbourne to Osaka Yacht Race. In real life, this double-handed 5500 nm race between these two sister cities, one deep in the southern hemisphere, the other high in the northern hemisphere, is run every four to five years, and is planned to be held again in 2025, so this race is a Prelude in partnership with the Melbourne Osaka Cup 2025 organising committee collaborating with the Ocean Racing Club of Victoria (ORCV), and the Sandringham (SYC) and Osaka Hokko (OHYC) yacht clubs. On this occasion, we’ll be racing the well-known First 40, a popular size of boat for a long-distance double-handed race. With the doldrums unavoidably lying across the track, you can expect to be at virtual sea for at least a month!
