2011-05-14 23:06:39 - Polars for Tampa - New Orleans
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?

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....

Andaman Islands PYOC 2025


The Andaman Islands are an archipelago, made up of 200 islands, in the northeastern Indian Ocean. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. These waters will be the theater of our next 240nm race in the ARCH 2025 series. Which one you choose depends only on you, i.e. your Elan 410 sport will leave the Andaman Islands on the starboard or port side.

Isla San Lorenzo RTI 2025


SOL’s SRC (Sailonline Race Committee) has taken us to some unusual places in the past, and San Lorenzo Island off Lima’s Callao peninsula is definitely another one. Housing a naval base and a penal institution, no vessel is allowed within 300m of its shores. Also, with no sources of potable water, it is a matter of debate whether it is an island at all, and not just a large rock. So, whatever you do, don’t be tempted to BBQ; you’ll be arrested and go thirsty! We return for the first time since 2018 to race thirteen potentially unlucky miles in J-30s; have fun!!

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
