Magellan
Post by iconPost by YourMomSA | 2019-03-19 | 22:26:16

Magellan looks possibly interesting. It's hard to figure out much about it without committing to do it. Anyone have much info yet?

I was able to get into toxcct's polars through the dashboard... Looks like the boat is a "Caravelle" with max speeds in the vicinity of 7.8 kts... that's with a C0 and foils in 20 kts wind. Seems humorous to be using foils and a C0 on a Caravelle, but I'm actually happy to see it as I had wondered in the past if we might ever see a Hermione with foils.

The boat also has horrible upwind VMG angles... but interestingly its fastest point of sail under 7 kts windspeed is TWA 70, so it isn't just a downwind slogger like Hermione.

The dashboard's map also confirms that you must pass through the Canaries, as well as through a gate off Caravelas, Brazil. If the fleet encounters an upwind approach to either, that could get tricky.

Has anyone determined whether or not this event has any other oddities, such as the food impacts in the hold Hermione events?

I see a better top speed of 8.115kts with a Heavy Gennaker, TWA 150°, Wind Speed 24kts.
That's a lot ! :)

Regarding the foils and C0 on a caravelle, yeah, that's pretty irrelevant, but I suspect they would have to update too much of their boat model to be able to fully support such old boats (IIRC, those ships don't have symmetric polars, regulars/modern sails have nothing in common with those old squared pieces of tissue).

What I find funny is the animations when you get to pick the options.
The radio is a parrot, the foils are racks of paddles, etc...

Regarding the race, you said it all. I don't think there will be anything like the food tank in the Hermione race, and yes, there are buoys and gates, but nothing hidden we should worry about.

VR has tricked me into joining the race with the surprise popup they put on the home screen and I'm almost in a rant mood again. As usual they leave us in the dark as to what awaits us - not even an in-game message this time.

The prospect of a circumnavigation in an unknown number of legs ("episodes"), at a top speed of 8 knots, does not seem particularly tempting to me, all the more so as the follow-up episodes will likely not be offered at a 75% discount.

But of course, a departure into the unknown is very much in the spirit of Magellan ;-)

About one month for this leg indeed. Pretty straight line because of the boat polars.

The Pacific leg(s) will be quite long - 2 - 3 months.

It looks like they posted a message stating that the event is a Category 3 but the Full Pack is being offered at the Category 5 price. I guess that's what they mean by the 75% discount.

I was thinking this event might be a good one to do on credits because it probably won't require much maneuvering and the fleet will be at sea long enough to gather a lot of cards... but I think the upgrades are being offered at the Category 3 price in credits, right?

The "incoming races" list now shows this as having at least 8 "episodes". I'm not sure how they'll do scoring for the overall event... Some episodes are Category 3 and others are Category 4.

I was interested in this originally, but I'm losing interest. I don't know how much I want to spend the rest of 2019 sailing slowly around the world. I like slow boats more than fast boats in short races... but long ocean passages in slow boats can be frustrating.

I have my personal Murphy Law for VR: the time you spend in a race and the effort you put on it are directly proportional to the the chance to slip into a new bug and/or some new “improvement” from VR that will screw your race
So I wish all the best to Magellan in his trip, I will follow from the pub

Have you seen the duration estimated for the leg 4 of the Magellan race ? ^^ 😵

According to the green color of the winch in VR, the best angle should be 60°, but Zezo shows 65°, why such a difference? I see that everybody follows the 65° not the 60° of VR, seems that people believe more Zezo than VR! But which one is wrong?
Post by iconPost by zezo | 2019-04-07 | 09:09:00
People believe in math.

VMG = speed*cos(TWA)

speeds for 60 and 65 degrees, C0:
tws:
[0, 6, 10, 14, 20, 24, 30, 35, 40, 55, 56, 70],

[0, 2.76, 4.01, 4.2, 4.4, 3.07, 2.28, 1.45, 1.2, 1.14, 0, 0],
[0, 3.36, 4.95, 5.24, 5.53, 4.17, 3.4, 2.52, 2.33, 2.21, 0, 0],

cos(60) = 0.5
cos(65) = 0.4226

4.01*05 = 2.005
4.95*0.4226 = 2.092

and so on.

You should not trust the router blindly. Sometimes it sails 2 or 5 degrees lower than the optimum. But you can trust the polars - here or toxcct's page.

Every now and then, the routing in Magellan suddenly seems to be running with polars from something else... something that can do 20+ kts. It tends to last for maybe 10 minutes and then I don't see it again for a while. I ask because I'm seeing that right now... Anyone else encountering the same thing?

Thanks. Wrong port on the load-balancer. Fixed. It was probably a Milti 70.

It's only used when the load on the main server goes above certain level, that's why you get correct result most of the time.

It seems like no matter how much time passes, the 16-day projection doesn't get any closer to the finish.
