Here is a proposal...
"One thousand sims, one thousand sailors..."
Maybe it can't work, and I admit maybe its nuts to even try...

But hey:
It could be huge fun, and if you join up,
you'll at least drown laughing.

I know, I know... Just don't think about it.
Close your eyes, get permission from your doctor or a parental consent letter,
and then click here:

You know us. In J-CLASSIC, fifteen teams and scores of sailors finished every single race over ten weeks and eight hundred sims.
We wont leave you on the water this time either...
In fact if you don't have fun, we guarantee your $L back!
(OK, I understand it's all free anyway... but did I mention the steak knives you get?!)
OK, forget that; grin. Let me know what you think; we're shooting for late February/ Early March:

<<snipped for brevity>>

I just read this and all I can say is...
COUNT ME IN!!!

This is definately my kind of event. I might even pull my Trudeau 32 or my Bluewater out of mothballs for this.

Jane, thanks for the article featuring the Nemo (and BBK) on your web site. I feel I need to clarify a couple of points...

The Nemo is based on (well, uses bits of) the public domain Tako scripts, which I think equate to v2.0 or v2.1. In this early version of the Tako at least, there was no windshadowing.

As you're probably aware, the Nemo can be set up to use two different sizes of sail. This applies to both the free and upgrade versions. Since the free one is aimed at beginners, its default sail is the small multi-coloured one. The Nemo-R upgrade is aimed squarely at racers and defaults to the silvery large sail. Although each size of sail uses the same polar, the efficiency of the rig differs - for the same wind in the Nemo-R, the big sail will make the boat go faster than it will with the small sail. To change rig on either version, left-click the boat to bring up the menu, pick "Rig Size", and then choose "Large" or "Small".

To keep things simple for beginners using the free Nemo Nantucket, each sail uses a different wind setting. The small sail uses 15 knots with no variance in speed or direction. This keeps the boat behaviour consistent while a beginner gets to grips with things like wind and sheet angles, and the effects of trim. The large sail uses the standard race wind settings used at NYC, complete with variance in direction and speed. A beginner who has progressed a little can try out some racing using the same settings as others who may be sailing the Nemo-R, or other boats such as the Tako 3.3.

Nomad? could you please cross post this on 'metaverse' as well, so everybody sees it. This is a somewhat unique feature of Nemo. I included it in the table, but didn't adequately explain it in the article. Changing the rig in the free version of the boat does indeed result in a power boost, and that feature should be pointed out.
Thanks also for confirming my impression that Nemo-R was intended as a One-Design racer. That justifies 'locking' many of the boat's features, to guarantee the fleet all sails the same boat.

I'll cross-post when I get a moment. Something I forgot to add...

The Nemo does use apparent wind. However, the true apparent wind is scaled down due to the scaled up boat speeds that are prevalent in SL. If apparent wind was modelled correctly with SL boat speeds, the boat would end up close-hauled no matter what point of sail it would/should be on.

Have you seen the recent America's Cup in RL?.. and the apparent wind angles of those boats when under speed? If I recall the Nemo is intended to be a fast boat? To see it sheeted like a slow one doesn't seem very consistent with the concept. Try sail an old Fizz 2.0, it goes with sails to close hauled under most angles.. but you have to first sheet out to speed up again.

I agree with Liv, but also with Nomad. It is true that "apparent wind is scaled down due to the scaled up boat speeds that are prevalent in SL". I may understand that a boat manufacturer, wants to provide boats having performance comparable to those already existing, even repeating the same mistakes than the others. It sounds "logical", or rather, the reverse could be frustrating for some. Mothgirl did the same at the time of Fizz 2, boosting Fizz2 performances to equal the Tako, even if Moth was not happy to do so, it was a general request from the "market".
Proposing the Nemo in two versions seems to me a very good idea. That said, even if the "slow/free" version has speeds comparable to Fizz, she is approximately 50 to 80% faster on a given race due to the absence of apparent wind. We are here at the border between arcade and simulation.
No doubt the "slow" Nemo is a good boat to start with, certainly well coded, enabling a wider audience to cruise along lindens waters and understand the basics of sailing. Those interested in "true" sailing and racing will quickly move to other choices in their learning curve. Among the good points of Nemo, I note the handling of sails and absence of gestures, and the onboard hud. However I regreat the absence of a lot of features (app wind, shadowing, full wwc support...).
I also regret the Flying Fizz doesn't appear in the "trainer boats" table by Jane. A Fizz in "fun" mode is the easiest boat to sail, and a Fizz in "Novice" mode" = Nemo + full wwc + wind shadow + app wind + race wind + mod for texturing + crew + "unlock" + ... for free also. For me, the Flying Fizz remains an unsurpassed boat to learn with a bit of realism.
That said, the market may differ from my own taste, and I wish the Nemo will meet a great success (I already adviced the Nemo as a good buy to some beginners).

[Nomad Zamani]

Yes, it is indeed case of striking a balance. The large sail Nemo is intentionally similar in performance to the Tako (not as quick downwind, but has the edge upwind). The small sail version serves both a beginner's boat and as a slower race boat in its own right - it's entirely possible to hold small sail Nemo races (the Type R uses race wind with either size of sail) that are slower paced and more conducive to tactical racing. The idea is to give sailors and RDs the option to have races at either pace in a convenient package. While the blast factor of the large sail is good, I do hope to see more of the slower tactical stuff.

As for realism in terms of the boat simulation, there are features we want to add, but we have to be mindful of the need to keep the code light in terms of load on the servers. Too much fancy stuff adds up to increased lag and slower sim border crossings. We do plan to add tstuff where practicable, but I think we'll be concentrating on optimisation of the existing boat for a while, with a view to being able to add new stuff later, hopefully with minimal impact on script/server performance.

[Jane Fossett]

I admit I'm still not sure what to think about 'attenuated apparent wind.' I even find the terms people use pretty confusing; the phrase "True Apparent Wind" seems an oxymoron.
Mothgirl Dibou had a nice discussion of the issues in her comments here: http://metaversesailing.wordpress.com/2 ... ild-winds/

As far as I can tell, the Trudeau boats, the Shelly, the Juli Design boats, the Jangars, BWind boats, and I assume the Fizz all use the real-life calculations to determine "Apparent Wind" forces that drive those boats. On the other hand, Takos, ACAs, Tetras and Trudeau boats built prior to Twenty have 'Real Wind" based engines. Wildwind boats state they use "Apparent Wind," but they really don't; they use an attenuated version of it, perhaps around one-third Apparent Wind, but the correction factors for the boats are unpublished.

A large part of the fun in RL cruising and racing is plotting a course, or determining tack points. It's pretty hard to do that however if you don't know the basic physics algorithm the boat uses, and if 'apparent wind' is creatively interpreted by different builders without providing the details.

In the case of Nemo, I'm not convinced it uses apparent wind: http://metaversesailing.wordpress.com/2 ... omment-598

In the picture below, the boat starts on a beam reach and accelerates to a boatspeed= 1/2 True Wind. The correct AWA should be around 62 degrees, but the boats wind angle indicator doesnt seem to change at all. It looks like a Tako or ACA33, but there's nothing wrong with that.

[Nomad Zamani]

I took a Nemo and removed the app wind scaling factor to exaggerate the change. Below are a couple of shots showing the boat static and moving.
