Trudeau ONE Upgrades to Fourteen!

Trudeau ONE 1.14 launched last Friday. It came quickly on the heels of Trudeau ONE v1.13b, an upgrade that fixed  a relatively minor tiller propulsion issue I wrote about two weeks ago. Back then, several sailors noted waggling the ONE tiller could inappropriately accelerate the boat under a small number of specific wind and heading conditions.

Although T-ONE v1.13b fixed that Tiller Trouble, the script changes induced a few new problems. Often ‘Perfection is the enemy of the good,’ and most sailors I spoke with were happy with the upgrade and willing to deal with a couple new glitches.

Jacqueline Trudeau wasn’t satisfied though, and the result is a quick new version: Trudeau ONE v1.14. The v1.14 boat got a pretty enthusiastic response from the beta testers I spoke to. They all noted that the new upgrade distributed last Friday was way more than a bug fix. It handles differently from prior ONE releases.  


I’m still looking at the boat’s performance, but let me highlight a few items:

1. Stiff is Better than Limp.
Most importantly, the boat now has a better match between visible luffing and sail propulsion upwind.
Under some conditions in v1.13b, skilled sailors noted that making the sails luff (flap in the breeze) could paradoxically increase boat speed. That problem is now Fixed. In ONE v1.14, ‘What you see is what you get.” A stiff sail at an attractive angle with a hard camber foil will give you the power thrust any racer longs for. And as any sailor knows, a droopy rig with limp, flappy sails when you blow on them is just no fun at all. You certainly won’t win any medals that way! 🙂

2. More Compatible, Less Tender ONE
Most skippers I’ve spoken with think the new ONE upgrade is easier to sail, and report it’s compatible with more diverse race conditions. J Trudeau confirms that impression, commenting that:

“[ONE v1.14] will still lose speed from excessive heeling, but correct sail trim is given a higher emphasis in determining performance. It is less tender than 1.13b, and can stand up to 10 m/sec winds better while singlehanded.”

3. Tiller Comes With Options
There’s a new ‘Settings‘ feature for the tiller as well. In SL nearly all boats change direction by tapping the keyboard L-R arrow keys; if you press the Left arrow key, you turn Left. It’s actually more like driving a car than using a boat tiller.  In RL sailing it’s different, of course; you need to move the tiller opposite the direction of your turn.

In ONE v1.14, there’s a Settings Card option that lets you chose the way the tiller responds (the default is still the standard vehicle mode).

4. Better Deviant Diagnosis
Correcting a bug pointed out by JoyofRLC Acker, ONE v1.14 now displays the wind variation rate value correctly! In retrospect, I think Liv Leigh and I confirmed Joy’s bug in J-Class boats last year too… I admit I totally forgot about it after that Regatta 🙂 . Kudos to JoyofRLC for bringing it up again, and Woots, its fixed!

5. Phantom Boom (this item’s not new)
Although its not a new feature in this upgrade, I thought I should mention that T-ONE has a phantom boom; this is notable since very few other Trudeau sailcraft have phantom rigs.

If you look at the image to the right, you’ll see what I mean. The boom in the image  just passed through the green buoy at the edge of the Queequeg raceline (indicated by red arrow).

A phantom boom gives you more options, and lets you adroitly snuggle up to marks and obstructions as you try to scrape off extra seconds in a race. 🙂


The improved responsiveness and compatibility of v1.14 is noticeable to most skippers on their first, serious sail with the new boat. However, documenting it will take more testing under a variety of conditions of wind, hiking, and heel settings.

So far I’ve tried the boat out using standard test conditions, and appropriately there seem to be only subtle differences between  the prior 1.12 and new 1.14 versions of this boat. The significant changes should show up with higher wind speeds and tests that push the boat’s performance.

Here’s a graph of ‘Speed Over Ground’ for v1.14 using a  baseline 5.0 m/s true wind speed. I use 5.0 m/s to get a baseline standard that isn’t complicated by heel effects or crew hiking.

The solid line above represents Apparent Wind (AWA) conditions and the Dotted Line represents the same data plotted for the Real Wind Angle (RWA). Boat speed is plotted on the y-axis in m/s.

As you can see, with this low wind speed the boat’s velocity peaks around 60° AWA (80-100 RWA). This max boat speed is over 60% True Wind, and with increasing AWA it’s followed by a rather linear decline in performance as the apparent wind angle grows larger. That’s pretty typical of prior Trudeau performance plots, and closely matches the charts I’ve posted for early versions of T-ONE. Go take a look!

Heel effects and hiking are still strong in ONE v1.14, as shown below.

With ONE v1.14 sailing upwind in an 8.0m/s true breeze, the boat heels significantly. Sailing singlehanded, a skipper under heel can greatly increase boat speed by shifting to windward position and balancing the boat. With a 50-60° heading AWA, a solo skipper can boost boat speed by roughly 30%. of course this will vary based on true wind speed and crew size, but its a huge racing tool.

I’ll get you the other data sets as soon as the sims cooperate and I have time to collect the data!

  1. Excellent tech work as usual Jane and “test team”.

    By other hand I have another remark., not specify for ONE but affects all sailing inworld. I’ve though you all SL and LL lacks a basic dynamics and climatics that must be solved for “an-step-beyond-of-a-bad-artificial-world” done different “plug-over-bug” to have a reliable “real-like-3D-world”.

    So, “what’ about the buoys?”. I relly don’t like we must set phantoms to solve “non-sense-specs” of objects as the usual buoys. How a buoy can stop a J-Class vessels?! OMG, that’s total regret about dynamics!! And then we use “phantoms”… I’m very dissapointed about that. The right behaviour its to use (always from RL rules) inflatable racing buoys the can be push and moved. And mark buoy style anchored that can be move and turn in some angle collision (you can found an excellent example of that kind of buoy from Linden marks), at my advice the best dynamics buoys inworld.

    Another RL rule, that turn in a fair sailing competition, it’s to avoid buoy contact by penalty turn. SL response it’s (logical for the bad 3D world we have) that is a hard penalty itself contact an OMG-inflatable-racing-buoy-that-stop-a-galleon. Let me do a big laugh for “technical LL programmers”.

    But if we penalty contacting buoy in a race, then we allow clean fair sailing, as RL does on most REAL sailing events. Check about that. I’m very tired of seeing and feeling that some “good skippers” turn sailing into catch. Forcing rule rights to extreme to get the law by their side.

    And we still design into fantasy specifations to make a lil’ more reliable artificial life inworld… So, so sad.

    Hugs Jane

      GRIN. I’ve been saying the exact same thing for the past eighteen months!
      The sculpted ‘buoy problem’ was finally (mostly) fixed, so I stopped arguing about it.
      But YES, give me a non-sculpted, physical nav marker any day.

      I disagree with your comment on only one point:
      If you are racing mid-sized or large boats over longish distances, and you have permanent positions for the race markers….
      I don’t think plastic inflatable tetrahedrons are very realistic.
      In those conditions in real-life, we all use fixed navigation markers.
      The question to ask is: “Is that buoy permanent or just for this race?

  2. Well said, elMegro; Those of us looking for realistic racing, we like good boats such as the One. We also need rule 31. No touching marks. If the marks can be pushed we need it badly. Moving marks will enable a skipper to push the mark and create an advantage for himself, squeeze in between the mark and a windward boat. It would be allowed in SL. Not in RL.

    • There’s a long history over Rule 31.
      In general, I think if we can use the RRS, we should.
      Often the consensus is that the full ruleset can’t be fairly used or enforced for a particular regatta.
      Well… ‘Fair enough I guess,‘ I respect the opposing views.

      However, I think in those situations you don’t need to ‘change the Rules.’
      The RD for a particular race just needs to announce that certain Rules will be ‘switched off’ for that event.
      That’s the RD’s choice for their fleet, it’s their call, and
      it doesn’t really impact SLSailing’s consensus over validity of the RL Ruleset.

      Armchair Binder pushed to change Rule 31 in the SL RRS.
      I admit Armchair is a far better sailor than I am RL (like so many others here).
      I also think he has an intuitive grasp of the Ruleset from a sailor’s perspect,
      and he has good sense about how Rules should be applied
      (unless, of course, he’s the offending boat when a protest is called 🙂 ).

      [PLEASE: anyone reading this, don’t ever tell AC01 I thought he made ‘sense’ 🙂 ]

      Anyway, I personally think we can, and should, enforce Rule 31;
      Anyone who feels their races would benefit without 31 can always ‘switch that Rule off.’
      I know many others feel differently, and I accept they have as good an opinion as I might have… prolly better. 🙂

  3. I agree Noodleqt,

    I came from wild RL windsurfing.
    In fact the only RRS I’ve learn, mainly, comes from SL events.
    But, not only on rules, plus all other involved: dynamics, sqm. rig area-polars results… all about specs must fit replica from RL.
    Fantasy apart, event steampunk style has a real physical impact.

    By the way, I’m never playing, I’m simulation testing, learning and feedback.

    I regret also naked sailing to give the hand to LL instead force ’em to do a good physical platform, IT and communications.

    Sadly, still PS3 online racings and HOME as well SAIL SIM EXTREME as the best real-like by far feelings about 3d worlds.

    Then profit for all of us, our unvaluable unknowledge of SL -not me 😉 – and work together sharing knowledge about WWC/BWind settings (I prefer call “climatics”) for a real like 3d world. Same covering physical-dynamics for any displacement heart, wind or water… let me the fire LOL 😉

    • I agree some specific sail race simulations have better features than Second Life. So… why are we in SL and related grids?
      I think the answer is obvious.
      Sailing solo on a desktop emulation will always be more accurate and faster than connecting to a global network full of compromises…
      but in SL we have a large community of friends who share similar goals and hopes.
      When Waypoint moved to USS three years ago, I wrote a short article about this issue…

      I feel the same today, actually prolly more-so.
      Sailors here are are good friends… I love them and learn from them always.
      SLSailing is not about playing a game; its about human experience and sharing.

      GRIN… and yup,
      maybe I’m just nuts.

    There are basically two reasons the touching the buoy mark rule was changed to allow touching. One was when you hit the buoy you bounced off of them, especially in the smaller craft. The second reason was a more difficult problem. The boats often had, and still have, invisible bits and pieces that would “hit” buoys even though visually the boat was clear of the buoy. I distinctly remember in races watching boats jump sideways as they brushed a buoy with an invisible part of the boat. Do you really want to penalize that effect?

  5. Hi Chaos!

    Fair observation. I see, of course. But the thing it was taken upside down.
    Must be the buoy instead the boat that’s bouncing. So any buoy builder must change their dynamic/phisical specs. About the invisiprims, its another tech, right. But today it’s possible to join material and unmaterial prims preserving each nature.

    So, not, not penalize the sailor, goes penalize the builder 🙂

    So many thanks… but back to the article and sorry for my controverse:
    The ONE its a very nice sailyacht that excels as well on racing as cruising.
    A love to sail.

    • Cough.
      This was a long discussion two years ago.
      I think it will be solved with MESH.
      I spent hours in ‘non-sculptie’ boats slamming into sculptie buoys…
      and more hours in ‘sculptie’ boats slamming into ‘non-scuptie’ buoys.
      I mostly agree with dear Chaos on stuff… he has a long perspective here and better tech skills than I do (by far), but I tried hard to prove this was a boat problem so I could make the issue go away. Every time it turned out to be a buoy problem.

      I’m very grateful to MTW who came up with a partial fix I could live with back then. I think we all still sail with that fix every day, and it still works ok unless you look too closely.
      I’m not complaining about it; it’s not a major obstacle for SL Sailing.
      I also believe MESH will fully fix the issue soon.
      Let’s not argue this point; it’s getting fixed from the ‘Top.’

  6. I must say…
    …thank you, to you all, specially Jane, Chaos and Noodleqt.

    Very interesting up-to-date view points about what’s happening inworld.
    Just to say, sorry, if any idea I’ve post results off or out. Anyway, my only interest it’s to get fun and feel so close as real it can does in THIS MAGNETIC SYNTHETIC WORLD…

    …Cause the only true it’s I’ve found friends INWORLD.

    Fair Winds!
    Back to the article, the ONE it’s a “tour de force” as other lovely boats has coming to our pleasure.
    Thank you Jaquie 😉
