Zinnemann 40 Catamaran


The Zinnemann 40 is the tremendous new catamaran from Zinnemann.

Specifications:
  • 28 Prims
  • 10.5m LWL (and LOA excluding bowsprit)
  • 12m LOA including bowsprit
  • 6.8m beam
  • 12m high above waterline
  • 0.8m draught

So far the 325 Zinnemann 40 catamarans that have been sold have sailed a total of over 73,342km (the equivelant of sailing across the Atlantic from New York to Liverpool 13.7 times).
Top 10 Features

3 Sails
The Zinnemann 40 has 3 sails. The upwind sails comprise of a 10 meter tall mainsail and a slightly smaller jib. These give great upwind speed of around 20 mps as well as exhilerating heel.

The Zinnemann 40 also has a large symetric spinnaker to allow it to continue to travel at speeds well in excess of 25 mps downwind as long as you can keep the kite filled.

The upwind sails and the spinnaker both use take their commands from completely separate keystrokes (or gestures).
2 Customisable
The sails, trampoline, hull, keels and rudders can all be customised with your own designs.
 

To customise your catamaran you can either buy off the shelf sails from companies like Nautical Notions or use our templates to create your own textures.

You upload your textures into Second Life and then log into our website where you add the texture keys to a form.

The beauty of this system is that whenever you upgrade your Zinnemann 40 your designs will automatically be used on your new boat.

SLSF Race Wind
The boat uses the official Second Life Sailing Federation Race Wind. The boat can also be toggled to use Second Life's ambient wind if you prefer.

Gestures
Rather than relearn all the controls for a new boat I thought it would be useful to use familar keyboard controls to operate the Zinnemann 40. So you still raise the mainsail with "raise" and park the boat up with "moor" or "dock".

I have carried on this strategy by basing the gestures on the ones Cory Copeland created for the Flying Tako and that most sailors use.

All Tako gestures work on the Zinnemann 40 as well as a host of new ones such as ctrl F2 to raise the sail or ctrl F8 to launch the HUD (useful on dodgy SIM crossings).
5 HUD
The Zinnemann 40 comes with a Head Up Display which you can share with your crew so you can both keep an eye on your performance. The HUD has a simple menu system which allows you to toggle between wind angles and boat speed. Future versions of the HUD will include a race timer and may include sail angle information.
6 Animated Helmsman
The helmsman's pose was created using Poser 7. In the current version it is not as advanced as the poses on TruCor's beachcat but future versions will include upgraded animations for the helmsman and crew.
7 Telemetry & Mapping
As you sail your Zinnemann 40 it uploads information such as your speed, windspeed and location to a central server. This will allow you to further analyse your performance against the performance of other racers and gives a better experience to race spectators who can view the position of the boats using online mapping.

Please note that there is a privacy option for these features.
8 Guest Skippers
Allow other people to helm your boat by adding them to your guest list on our website.
9 Copy Permissions
Because of the intermitent sim crossings we have made the Zinnemann 40 copyable.

(The Zinnemann 40 is no modify and no transfer)
10 Free Upgrades
And last but certainly not least we will be providing free upgrades to all future versions of the Zinnemann 40 for ever.



Version Upgrades
The following features where added to new versions of the Zinnemann 40:
v1.2 Animated HUD Dials
A new Head Up Display has been included with animated dials.
v1.2 Guest Skippers
You can allow other people to helm your boat by adding them to your guest list on our website.
v1.2 Spinnaker Rules
The spinnaker has been edited to behave more realisticly by collapsing when not correctly set and adding proportional speed to depending on how well tuned it is.
v1.2 Nudge and Rotate Commands
If you should be unfortunate enough to ground your catamaran on some rocks, a jetty or even a passing whale you can now get yourself out of bother by using "nudge" followed by the direction (e.g. "nudge n" or "nudge e") to move your boat 10m in that direction. You can also type "rotate" to spin your cat 90 degrees in a clockwise direction.
v1.2 SLSF Start Line
The Zinnemann 40 is now SLSF start line compatable including providing it with Flying Tako style helmsman letters and ID number.
v1.3 Sleep Mode
To help reduce sim lag and global warming the main scripts can be turned off when the catamaran is not going to be used by typing sleep before you stand up. Typing awake will leave sleep mode.
v1.3 New Default Wind
The default wind direction was set to 250 degrees and the default speed was set to 18 m/s to reflect racing conditions. The benefit of this is that if a catamaran has to be reset during a race (e.g. if it gets stuck on a rock) then it will not loose race wind.
v1.3 Sail Number Retention
The sail numbers is no longer lost when the catamaran is moored.
v1.4 Password Integration
You can set your password for www.zinnemann.com from your boat.
v1.5 Tighter Turning Circle
The control surfaces have been enhanced to allow to cat to be turned in a slightly tigher circle.
v1.5 Enhanced Nudging
To aid nudging out of difficult positions the cat levitates to 10m in the air. Nudging over sim boundaries prevented in order to stop the cat travelling offworld.
v1.5 Toggle Wind
You will be able to toggle between Race Wind and Second Life wind (just type wind). This will allow you to have a more leisurly experience if you choose. The implementation of Race Wind will also be edited so that the wind bearing and speed fluctuate.
v1.5 Additional Gestures
The result of the poll came out in favour of support for sheet gestures for all sails 9 votes to 3 so this has been added.
v1.5 HUD Permissions
The HUD is now transferrable and can also be requested by guest skippers.
The following features are being added to the next version:
v1.6 Demo Version
The free demo version will have all the features of the full version and will have no time limit. The only constraint will be that it will only work in specific sims.
v1.6 Water Effects
Wakes from the stern, rudders and bows will be created using particle effects.
v1.6 HUD - Race Timer
An additional view will be added to the HUD to automatically start a two minute countdown when it hears the command "+start" on the standard voice channel. The timer will beep as the time nears the start and continue counting for the whole of your race.
v1.6 HUD - Compass
An East pointing compass will be added. The compass will be gimbaled so that the amount of heel is also visible.
v1.6 Multiple HUDs
Multiple HUDs will be positionable onscreen.
v1.6 Enhanced Nudging
Further improvements will be added.
v1.6 Docking Improvements
v1.6 Protest Shouting
When a protest is called in a race it will be shouted by the cat. 		 
v1.6 Wind Improvements
As well as changing the direction that Race Wind is supplied in two new wind features will be added. Skipper Wind will allow the skipper to set the wind information. Lock Wind can be used in race wind mode to stop the Zinnemann 40 from looking for new race wind.
v1.6 Spinnaker Improvements
v1.6 HUD - Sail Angles
If the result of the poll is positive then we will add the sail angles to the HUD. Vote Now.

Likely Future Enhancements
Here are the likely future enhancements that your free upgrade will entitle you to:
Map Provision
You can ask the cat to give you a copy of the latest race maps.
Crew Roles
If a second avatar is travelling on the vehicle then trimming of all the sails would only be possible by the additional crew member.
Enhanced Poses
The helmsman and crew will both have their poses enhanced to include changing their position to the windward side of the boat. The helmsman and the tillers may also be animated to respond to changes in the helm angle. There are no plans to animate the crew member to hike out on a trapeze because this is unrealistic for this size of boat.
Inner Spinnaker
An additional prim will be added so that the spinnaker looks better when viewed from the side. The spinnakers will also be shrunk when not in use.
More Customisable Textures
At the moment 12 of the 28 prims are customisable. A further 6 spar and tiller prims will be made customisable.

Lifting Keels
The centreboards will be liftable to allow the boat to travel faster downwind. Be warned this will also create more leeway on other points of sail if you forget to lower them again.
Customisable Wind Vane and Sail Numbers
Just what you have always wanted - the ability to change the colour of your wind vane and sail numbers to match your sails.
Set Camera Position
You will be able to adjust the view of your cat via a dialog.
Apparent Wind
Wow, where would we start with this? It has a certain appeal and may be added if it does not create too many programming headaches.
 
Unlikely Enhancements
There are some features which are unlikely to appear in future versions. If you feel stronly that any of these features should be included please IM Hans:
Windshadowing
To be done realistically windshadowing requires the effect to be felt up to about seven mast heights away (i.e. about 84m). Windshadowing is also not as noticeable in the moderate wind speeds that the cats are raced in as they are in lower wind speeds.
Capsizing/Pitchpolling
It is unusual for multihulls of this size to capsize in moderate winds and calm sea states (though not unheard of). If this ability is to be added then it will be once the catamaran detects wind gusts.


Known Issues
The following known issues will be resolved in future versions:
Eliminating HUD Crosstalk
The HUD communicates by whispering on a static channel. In theory this means that your HUD can be updated by other boats which are extremely close. In practice boats have not been sailing close enough for this to be an issue.
Mooring
The moor command is required twice in order for a level moor to be attained. The cat does not moor at sea level if it was heeled.
Nudge "Kangerooing"
If using the nudge feature when against some obstructions the catamaran will go into a fast loop of bouncing up and down trying to get past the obstruction.
Sail Display
We have temporarily disabled the facility to hide your sails when moored.
Wind Direction
Changes will be made to use counter-clockwise wind bearings.

Lag Stats
A Zinnemman 40 draws 0.011ms in sleep mode (wake mode adds 0.003 to this and each avatar adds 0.005).

This compares to a Tako which draws 0.018 (and 0.003 when scripts are set to not running).
