Trudeau One: FAQ

One – getting started

1. Rez the Trudeau One from your inventory folder, preferably in a body of water

2. Make sure to *turn off* any AOs you might have on, rightclick the hull and sit (please wait until One gives the “Ready” prompt)

3. From your inventory, rightclick the “Trudeau One HUD” object and select Wear – the default location is the lower center of the screen. You may select it and move it around as you like.

While there are a complete list of commands for monitoring and changing your yachting experience,  here are the essential ones that will get you out on the water:

Chat commands:
/1 raise  <— raise the sails and get underway.
/1 moor <— lower sails and bring the boat to a stop.

Key commands:
<left> and <right> arrow keys <— steer the boat.
<up> and <down> arrow keys <— to let the sails in/out

Or just click the corresponding buttons on the HUD – the up arrow raises the sails, the down arrow lowers them. the L and R arrows let in/out the sails (the main and jib are controlled from the right hand dial, the spinnaker from the left hand dial). The anchor icon stops and moors the boat.

A basic rule of sailing – in RL and SL – is let the sails *out* when sailing *with* the wind, trim the sails *in* when sailing *into* the wind. OK, so which way is the wind blowing, weatherman? The windvane on the mast will show you wind direction, as does the HUD. Another basic rule is that you can’t sail directly into the wind – 35-45 degrees to either side is about the closest you can effectively sail. If you see your sails luffing (flapping), try bringing them in. The closer you are sailing into the wind, the closer the sails need to be to the centerline of the boat.

When you get some time – please read through the “Sailing the Trudeau One” notecard – the One has a whole list of new features!

OK – no more rules, let’s sail!

Sailing One

Thank you for your purchase of the Trudeau One, inspired by a well known Scandinavian one-design keelboat from the 1930s that has developed through the years into actively raced fleets in locations across the globe. From Norway to Long Island Sound, from San Francisco to Bermuda. Have you guessed that RL inspiration boat yet? It has truly international appeal, you could say.

One is the first Trudeau sailboat with realistic perfectly curved all-sculpted sails. On top of that, these sails are scripted to really luff. No need to keep your eye fixed on that sail angle figure – One will let you know inworld, visually and aurally, about your sail trim. Actually, you won’t be able to keep you eye fixed on that sail angle figure as it is not to be found anywhere. One is the first Trudeau boat that is truly sailed by your senses.

There is a lot of reading in this card, ignore it at your peril Otherwise refer to the included notecard “Getting Started” for the basic initial operation steps.

The settings CARD

———————-

In the boat’s contents you will find a modify permissioned notecard — settings — which allows you to modify some of the boat’s – you guessed it! – settings:

// channel for listen on for voice and/or gesture chat commands. Avoid 0 BY ALL MEANS!

// If you are a racer, we suggest using the numerical part of your SLSF Sail number

ChatChannel=1

// skipper positioning

SkipperPos=<-3.0,0.0,.75> // <fore/aft, port/starboard, up/down>

SkipperRot=<.0,0,0>

// camera settings

CameraLocation=<-10.0,2.5,3.0> //sets the camera position in meters relative to the boat – <fore/aft, port/starboard, up/down>

CameraFacing=<0.0,0.0,1.5> //sets the direction camera is facing, relative to the boat – <fore/aft, port/starboard, up/down>

//how many degrees off the optimum sail set before luffing starts.

//also number of trim degrees when setting the sails from the keyboard (up/down arrows) :

LuffThreshold=5

//keys for shifting skipper – 0 – Page Up/ Page Down, 1 – Shift Left/Right Arrows (value 1 disables steering in mouselook)

ControlKey=0

//loudness value for luffing sounds – from 0 (off) to 1.0 (full)

LuffVolume=1.0

// list of avatars allowed to skipper the boat. Add as many as you like.

// make sure to use exact spelling and Punctuation

skipper=Jacqueline Trudeau

IF YOU PLAN ON RACING YOUR ONE, IT IS HIGHLY RECOMMENDED THAT YOU CHANGE THE ChatChannel SETTING! And also change your gestures to match. This helps reduce the control chat lag when a large group of boats are gather together, such as a regatta startline.

Skipper and Crew

—————–

The Trudeau One can be sailed either solo or with the assistance of a crew, everyone involved wearing a HUD or issuing chatline commands. In that case the skipper is typically responsible for casting off, steering and mooring the boat. The crewmembers for sail handling under the direction from the skipper as well as moving about the boat to keep heeling under control. The HUD object is copy and transfer permissioned, so Shanghai *your* crew by dropping this HUD on them. (Please see the “HUD Transfer preparation” section below)

One’s skipper position is “sitting” anywhere on the hull, the skipper can slide from side to side and effect the trim of the boat using the PageUp/PageDown keys (or Shift LR Arrows depending on the value in the settings card).

In addition to the skipper, the two crew/passenger sit locations are any cockpit bench and the cockpit floorboards/cabin doors. The crew controls his or her position using the left-right keyboard arrows – these positions effect the heeling angle of the boat and it’s speed potential. There are 5 positions per crew location, a heel neutral center position and 2 each port and starboard. We’ve tried to balance the amount of heel offset (after all, this is modeled on a 33ft keelboat displacing nearly 4 tons) with an actual observable effect. You will see a few degrees of heeling offset depending on the crew position. The 2 crew and skipper locations are additive. Theoretically, with a full complement of crewmembers aboard all synchronizing their movements, it would be possible to keep the boat nearly flat on all points of sail. That would have a dramatic effect on the boat’s speed. Want to win races? Recruit and train a crew.

A nice relaxed animation is built into the spinnaker bag (also known as the “turtle”). It is recommended that you sit here only when moored and not underway as the turtle shares the same prim as the spinnaker (though SL being SL that probably the first thing people will try

If you find the animation locations are not quite correct for your avatar, each sitable prim has an editable notecard called sit config. Edit it’s contents (some trial and error will be involved) to suit and save:

offset=<-1,-.57,-.81> ‘Fore/Aft, Port/Star, Up/Down

rotation=<178,0,-10> ‘Roll, Pitch, Yaw

Key Controls:

—————-

Use the <left> and <right> arrow keys to steer the boat.

Use the <up> and <down> arrows to let the sails in/out

Chatline Commands (all preceded by the /1 channel designator)

—————————————————————————–

“raise x” — where x is “jib”, “main”, “sp” or “all” (or no parameter) for both main and jib — raise the sails and begin sailing.

“lower x” — where x is “jib”, “main”, “sp” or “all” (or no parameter) for both main and jib — lower the sails and stop sailing. Note that the boat will continue to drift. Lowering the spinnaker will autoraise the jib if the main is also raised.

“moor” — come to a complete halt and reset the boat to non-physical state.

“dock” — returns the boat to the dock location entered with the set dock command. It’s best not to issue this command if your dock location is more than a few sims away.

“m dir x” — where dir is p (port) or s (starboard) and x is a positive number. sheet in or out the mainsail by x degrees in the direction of dir.

“j dir x” — where dir is p (port) or s (starboard) and x is a positive number. sheet in or out the jib by x degrees in the direction of dir.

“sp dir x” — where dir is p (port) or s (starboard) and x is a positive number. Controls the trim of the spinnaker (please see discussion below).

“gybe x” — where x “sp” — transfer the spinnaker, using the same angle, to the opposite side of the boat.

“tack x” — does exactly the same as gybe Note that the main and jib automatically gybe and tack with the wind (What! On a Trudeau?!?!).

“showsail” — raise the sails for display, without initiating the sailing physics

“pp” — toggles the boat phantom/non-phantom while sailing. Good for getting under those low bridges and other tight spots.

“id xxxx” — where xxxx is *up* to 4 characters. Appends the characters to the boat name for regatta identification. Adds characters if missing, changes characters if they are already present and different.

protest x — where x line of text. Relay SHOUTS the text from the boat – used for regatta protest situations.

The SET commands

———————–

The following command – set – is used for boat configuration options which are saved between sailing sessions. The set commands are as follows (don’t forget the /1 prefix):

“set alpha x” — set sail opacity (“set alpha 25″ sets the sails to 0.25 alpha, or 75% transparency).

“set color x” — set the hull to one of several traditional color schemes, where x can be: “black”, “blue”, “blue2″, “green”, “red”, “white”, or “bright”. We invite you to sample the built-in color schemes, we are quite proud of them – they are based on actual RL boats.

“set dock” — sets the return location for the dock command.

“set wind” — see discussion below.

The set command by itself lists all the parameters the boat has stored:

/1 set

[19:31] Trudeau One whispers: WindDir: 0

[19:31] Trudeau One whispers: 11.000000

[19:31] Trudeau One whispers: WindDir+-: 0

[19:31] Trudeau One whispers: WindSpeed+- : 0.000000

[19:31] Trudeau One whispers: Wind Change Rate: 0.000000

[19:31] Trudeau One whispers: Sail Alpha: 100

[19:31] Trudeau One whispers: Dock: Isla de Jacqinda (2, 63, 19)

The SET Wind command in detail

—————————————

The /1 set wind command turns on an artificial wind that overrides the fluky SL winds. It allows input of skipper defined wind parameters.

/1 set wind dir speed dir+- speed+- rate (all parameters separated by spaces)

Example:

/1 set wind 225 8 20 2 1

As with all the set commands, the boat will save your settings into it’s “firmware” for future sailing sailing sessions (as long as you save the vehicle back into inventory).

The parameters explained:

dir: sets average wind direction in degrees, CCW from due East. Must be a number between 0 and 359. (in SL, dir 0 is wind direction due East, dir 90 is wind direction due North. dir 180 is wind direction due West, 270 is wind direction due South, etc.)

speed: sets average wind speed in m/second. Must be a number between 1 and 50

dir+-: sets range over which wind direction will vary from the average wind direction, in degrees. Must be a number between 0 and 45.

speed+-: sets range over which wind speed will vary from average wind speed. Must be a number no greater than the average wind speed.

rate: sets rate at which wind speed and direction will vary, +/-. Default is 1. A rate of 2 will double the rate of change over the default rate.

Only the first two parameters are required: /1 set wind 225 8 .

The command will continue to use the range and rate parameters previously set.

Racewind Windsetters Interaction

—————————————–

The Trudeau One is compatible with the SLSF Race Wind system used in yachting regattas throughout SL.

Upon hearing a windsetter’s broadcast, a dialog indicating the windsetter source, it’s broadcast settings and 3 options are presented to the skipper.

1. The Accept this option loads the racewind settings and turns off any further windsetter listens (and prompting) until the skipper stands and re-sits. The settings can be overwritten by the skipper with a /1 set wind command.

2. The Ignore this option does not load the settings, but keeps the racewind listen active. Be prepared to get dialoged by those persistent windsetters!

3. The Ignore all option does not load the settings, keeps the current boat wind settings and turns off any further windsetter listens (and prompting). It remains in effect as in the “Accept this” option.

One’s masthead windfly turns red while under racewind.

Real and Apparent Wind

—————————–

The numbers input with the set wind command or captured from racewind windsetters represent real-wind values while wind speed and direction values displayed on the HUD and the masthead windvane are apparent-wind values. So what is the difference??? Real-wind does not factor in the boat’s movement for wind strength/direction values whereas apparent-wind does.

Please see this page for a full detailed discussion – http://www.sailnet.com/forums/racing-articles/20644-understanding-apparent-wind.html – but generally speaking, apparent-wind strength will be greater than that of real-wind when sailing into the wind, and less when sailing before the wind. As long as the boat is moving forward, apparent-wind will seem to come from a direction closer to the bow of the boat than real-wind does. The faster the boat is moving, the more pronounced the apparent-wind effect is. This is what accounts for the difference on what you see on the HUD compared to what was entered in the set wind command. As skipper, you will need to take the apparent-wind effect into account when deciding on optimum points of sail for getting from locations A to B, sail sets, spinnaker deployment, etc.

The HUD

———-

The 􀀂 , constructed of mahogany and bronze, provides button control for the common boat handling commands:

Raise, lower, sheet in/out for the jib and main combination and spinnaker (spinnaker also has tack button).

Anchor (moor)

Info button toggles the status text display for those who desire that data in a text form.

The following sailing status indicators:

Boat Speed: speed of the boat over the sea bed in m/sec.

Wind Speed: apparent wind speed in m/sec.

Apparent wind direction relative to the boat.

Water Depth: Black indicates > 12m, yellow <12M, orange < 9M, red <7M.

The HUD also has within it’s contents a notecard called settings.ini. Edit this card if you wish to change:

the number of degrees the sails are set with each click:

DegreesPerClick=5

the color of the HUD text display (in the standard LSL RGB color vector):

TextColor=<0.96,0.58,0.17>

The HUD may be moved around and resized while onscreen. If you decide to resize the HUD, please work with a copy and stretch it *slowly* as it’s been observed that not all parts of the HUD resize at the same rate if stretched too quickly.

Trudeau Info-HUD

———————-

Also included is this minimally processing HUD which gives text-only info updates specifically for users (racers usually) who issue commands through the chatline. It’s been reported that using this HUD can reduce lag in sims crowded with regatta boats.

HUD Transfer preparation – IMPORTANT NOTE!!!!

———————————————————-

*******************************************************************************************

You may be used to Trudeau HUD with a “sync” button it. Our more recent HUDs do not have this. If you want to drop a copy of the HUD on someone else so that they may help you sail her as described above in “Skipper and Crew”, please do the following.

1. Rez the HUD inworld.

2. You will see the message on the chatline “Trudeau HUD (<your name>’s boat): Channel burned in for <your name>”

3. Take the HUD back into inventory.

4. The HUD will now be titled “Trudeau HUD (<your name>’s boat)

5. Give that copy of the HUD to your crewmember (explain to them it’ll be good for *your* boat only)

********************************************************************************************

The Camera HUD

—————

One of One’s design goals was to implement a dynamic camera that could be positioned and aimed in various locations on the fly (as opposed to the “static” camera whose values are set in the settings card – changes that can only be seen after resitting). After working with the Linden Scripting Language camera functions it was apparent those goals would remain out of reach. No matter what, the camera always wants to point in the direction the avatar is facing. It is not possible, for example, to park the camera 5 meters off the beam and point it in the direction of the boat and follow along as the boat makes it’s way.

We have included the dynamic 􀀁 and you may wish to try it out. The center button turns the dynamic camera on and off and the arrows position the camera from side to side and up and down (facing forward as indicated above). The scripted camera in the HUD normally puts the camera about 3m behind you – the effect is about the same as the standard static camera’s default location. You can zoom in and out using Alt-mouse-drag or the SL viewer’s camera control zoom and the scripted camera will relocate back to that 3m position. HOWEVER, using your mouse trackwheel to zoom will override the HUD’s distance setting and REMAIN at that zoomed out (or in) setting until you trackwheel back in (or out). Why is this important? When the camera is zoomed out, you are no longer able to hear One’s sound effects which are important aural clues as to the sail trim. This is to be expected, as that is SL’s standard behavior – volume rolloff the further you are away, visually, from an sound emitting object.

However, you can change this sound behavior in SL somewhat in Preferences, Audio & Video, Rolloff Factor (1x viewers, we have no idea where to find it in 2x). A smaller value than the default 1.0 will extend your ears (at the expense of also hearing any other objects cluttering up the SL soundscape). Play around with it. The best advice we can give is keep the camera close to the boat and it’s sounds.

Sail Trim

———-

One’s sails will give you inworld indication as to whether they are in or out of trim. Raise the sails, you will see them flapping away in a highly animated fashion. When fully raised they will swing out, untrimmed, in the direction of the wind. This minimizes the boat’s initial heeling motion, preventing embarrassing dockside accidents Trim the sails in, the luffing (flapping animation) of the sail will decrease and when the correct sail trim is found for your point of sail, the sails will billow out and fill with the wind accompanied by a satisfying “thwap” sound.

To find your correct trim. The real life sailing there is a saying – “When in doubt, let it out”. When the sail starts luffing, trim it in. You will then be *close* to optimum trim. How close? See the LuffThreshold option in the settings card. That figure is the number of degrees set beyond optimum before you see luffing. The default is 5, which is a good compromise between racing and cruising. Serious racers would probably not settle for up to 5 degrees out of trim and can reduce that figure, the downside being more frequent luffing and sail adjustments. OK, I guess that is not a downside for racers, rather an important part of the game

If you are pinching (sailing close into the direction the wind is blowing), fall of the wind until the luffing stops – generally it’s best to avoid sailing within 35 degrees of the oncoming wind direction.

Another note about the sail trim. Visually it is different from previous Trudeau boats and probably every other boat in SL. Typically, for an apparent wind angle of say 40 to 45 degrees, SL boats have the boom at a 20 or 25 degree angle – sticking out beyond the boat. However in RL boats, when close hauled you will find the boom in tight along the centerline. One is closer to RL in that regard. There is no “zero” degree trim on One. In fact there is no trim less than 15 degrees to either side (no need to since ONE can’t point above 30 degrees into the wind anyway). One’s “centerline” trim is actually 15 degrees, the port or starboard tack indicated by curvature of the sails. Also One’s sails at maximum trim do not stick out completely perpendicular to the centerline. Due to the curvature in the sail sculpty, the standing rigging would cut through the main at 90 degrees So on One the maximum trim *looks* more like 80 degrees. Keep that in mind when running downwind.

The Spinnaker

—————–

The chute, when hoisted, replaces the jib – it’s effect kicks in when sailing off the wind – from about a beam reach. You will see a penalty if deployed when going to the wind (collapsed) or trimmed to the wrong side of the boat. Trim-wise, the spinnaker behaves like every other sail in the Trudeau fleet – it is variable between the range of 45 and 90 degrees.

The spinnaker sail itself is generally trimmed, along with the mainsail, to the opposite side of the boat from where the wind is blowing (the lee side). That is true except for the trim position for a run. Then the spinnaker sail should be trimmed to the opposite side of the main to avoid the wind blanketing by the mainsail (similar to a main and jib “wing and “wing”)

Here are some tips for handling the spinnaker:

1. The effect kicks in just past a beam reach. When collapsed above that, harm will be done to your headway.

2. When raised, the spinnaker will try and match the trim of the main. You may have to adjust it right away, depending on your point of sail.

3. The spinnaker will give you indication when:

Sailing closer than 90 degrees into the wind – violent “collapsing” animation.

The spinnaker is trimmed to the “wrong” side – a less violent “collapsing” animation.

When out of trim by ~10 degrees (high or low) on the correct side.- a less violent “luffing” animation.

Each condition above introduces a penalty to the boat’s potential speed.

It can be a subtle exercise in determining which side of the boat the spinnaker should be trimmed to. Follow this rule of thumb – the spinnaker pole is ALWAYS on the OPPOSITE side of the boat from the boom . When the spinnaker is trimmed to the port side, the pole will be over the starboard side and vice versa. Confusing? Yeah, me too – give me my gaff rigged catboat

Although the spinnaker won’t luff if you are within 10 degrees of the correct trim, for maximum thrust try to get the spinnaker *as close to your main angle* as possible. You can tell the boat lifts off when you have found the sweet spot.

Wind Shadowing

———————

Wind shadowing is a phenomenon well known to RL sailboat skippers. Though complex and chaotic in physics, basically it comes down to the loss of wind force hitting your sails due to another object’s presence between you and the wind. These objects can be structures or trees on the shore, landmass topological features, but in regattas it will likely take the form of a competitor’s boat

If you get in the lee of another Trudeau One, your wind will be shadowed as well. The effect is like a lighting instrument – intense and focused between boats in close proximity to one another (like a spotlight) , less intense, but more diffuse and spread out with distance (as in a floodlight). The maximum range for the shadowing effect is a 100m radius between boats. Plan for it in your tactics when racing your One!

Allowing Others To Skipper Your One

——————————————-

Edit the boat’s settings card and add the name(s) of the avatars that you want to give skipper permissions to:

skipper=Jacqueline Trudeau

Add as many as you wish:

skipper=Jacqueline Trudeau

skipper=Larinda Cordeaux

skipper=Taku Raymaker

As the actual owner of the boat, you do not need your name in this notecard. You will need to give the skipper a copy of the HUD object.

The Mooring Objects

————————-

Touch the forward deck cleat and you will be presented with a menu of mooring object options – boat side fenders, buoy, etc. One will rez these objects in the proper positions. Keep in mind these are freestanding primsets and not attached to One. They will derez themselves when One gets underway, or within 30 seconds if One is moved manually or taken back into inventory.

The Drydock Wedges

————————-

If rezzed over land instead of water, the One will autorez wedges underneath her hull to keep her upright. This primset is not attached to the boat, so if you wish to move the One around, please select both the boat and wedges before moving.

The Sail Customization Files and Notes on Modding

————————————————————-

One comes standard with her period correct sail textures and insignia. You may wish to design your own custom sails from the templates found in the link at the beginning of this card and we’ve included two separate ways of loading your custom textures. The first is the notecard called sails.

􀀃

Replace the card’s texture UUIDs with yours and drop it into One’s contents.

The second is a script for those who may wish to distribute their custom sails and not expose the UUIDs. Follow the instructions in the included script _customSailLoader

􀀀

and set the script as no-mod before distributing. This also goes in One’s contents.

There are those out there that like to get into the nuts and bolts really mod a mod-permissioned boat, removing, renaming, swapping out prims. Keep in mind if you do a lot of this, as she depends on certain prims named with specific names, One may stop working
