To help you choose, I've just added the Young 11 polar to my blog. The First and the Class 40 were already listed.

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

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.

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?

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:

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.

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

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?

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

TuziTekwini TIMED Race 2025

Sailonline is delighted to have been invited to partner with the King Shaka Yacht Club (KSYC) of South Africa to bring a virtual version of the Tuzi Tekwini Ocean Raceto our online community.
The Tuzi Tekwini Ocean Race is a near 90 nautical mile race down the east coast of South Africa from the port of Richards Bay to the port of Durban. Achievable in a single day and seen by some as an easy mile-builder, the course is more tactical than some think and should not be underestimated. This iconic race promises to be an unforgettable experience for yachting enthusiasts.
Our online version of the race will be a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have 13 days and 11 hours to test your skill and decision making after the race opens.
