Why delete them??
I have many races just stored in a zip file ;-)

Yes... infinite drive space has really led to some bizarre habits! heh

The fleet is mostly home. Could you send me another archive AGage? Thanks :-)

edit: or WhyNot! Sorry read too fast

Tom: I think that has to be covered by someone who can calculate the numbers. All I can do is estimate, which you can do yourself....
1) You can hover the mouse over the polar in the client to get this information
2) There is a program available which can load SOL polars (even the IMSYC), display them and also give you exact speed info by holding mouse down over the polar

What a bunch of un-observant, amateur puddle-splashers we are, to have not noticed the elementary fact that a boat cannot sail downwind faster than the wind speed.
Aside from the fact the TWS is in m/s, 6 is not unique in that all columns show this 'feature' - if you look harder you will see all the faster boats have this similar profile (ie Katrinautic?).

Why list TWS in m/s yet SOG in kn?? Well m/s is just as common a unit for TWS as kn is, yet SOG is always specified in kn - I agree it is confusing, but in this case it lets polars use nice round numbers, 2.0 is easier than 3.8868898 ;-)

BUT, as all polars had the same TWSs, it is the curves that describe the performance profile that matter, not the raw numbers, so it doesn't make much difference here.

Still, using tools to view/analyze the polar(s) makes like much easier - and besides, all the polar data was there for all to see/analyse well before the race - and what makes you think no-one noticed this 'anomalous' BS curve and just didn't post about it ;-)

Anyway, these aren't intended to be real yachts... We could create whatever we want in a polar to use on SOL - realistic is nice but not necessary...

Aaron, hunkering down below my desk - with my helmet on, I beg to differ.

The contentious curve (TWS 7.8 kn) in uprisings polar has a a "bulge" between TWA 140 and TWA 180. The boatspeeds there are all the same 9.7 kn. I have never seen a polar like that, and I challenge any designer to design a boat, sailing faster than the wind - within the IMSYC rules - at TWA 180.

And comparing with katrinautic. At twa 180 TWS 7.8 - the katrin does 5 kn. uprising does 10!

I do not agree with tour statement that the "katrin has a similar bulge"!

Still friends - I hope:)

76: How do I send the grib files to you? Do you have a "junk e-mail addy - where you let ppl you don't know send you stuff.

All of the boats are IMSYC-rule compliant by definition. The VPP won't run unless they are.

This has nothing to do with whether a fast IMSYC boat would be fast IRL. The venue isn't Valencia - it's SOL. The boats that I "designed" would be dogs in real water, but they are fast within the rules.

I mentioned in one of the first posts that this exercise is sort of mirror-image to designing real boats. Designing to "rule" you normally want a boat that rates slower that it really is.

The downwind performance of Uprising is a glitch, but it makes no difference to us :-).

Haugesund to Reykjavik 2025


In late April 2016 Draken Harald Hårfagre, the worlds largest viking ship built in modern times, left her home port in Haugesund, Norway and sailed off for a challenging voyage across the North Atlantic Ocean.
The aim was to explore and relive one of the most mythological sea voyages – the first transatlantic crossing, and the Viking discovery of the New World, more than a thousand years ago. History tells us about the Viking explorer, Leif Eriksson, who discovered America over 500 years before Christopher Columbus. The expedition was all about exploring the world, just like the Vikings did.
Sailonline is racing the 1000 nm first leg, from Haugesund, Norway, to Reykjavik, Iceland in our Farr 400. Let us sail in the wake of history on this epic adventure!

Africa by Sea - Swakopmund to Maputo 2025


Time again to continue our exploration of Africa by Sea, which now takes us around the tip of the continent at Cape Agulhas and up the coast of South Africa to Mozambique’s marvellous Maputo, where we should find good anchorage in the bend of the Rio Espirito Santo (Umbuluzi) once we’ve cleared the 60m high Maputo - Katembe suspension bridge. It’s 1900nm and we’ll be glad to be sailing our comfortable and sturdy Xp-55, as we will certainly experience more headwinds!
