Information for boat builders.
When the HUD first loads, it will search for the nearest copy of the correct boat and try to connect with it.
If the search fails, move closer to the boat and try again.
Some boats will require that the owner of the boat give permission to allow you to connect.
If you wear the HUD first, then rez a opy of the boat, you can ask the HUD to search again with the SYNC button in the settings page of the HUD.
Or you could just detach and re-attach the HUD in that case.
Here are most of the icons and controls that can appear on the Sailing Ship HUD and what they are supposed to mean:
|These are two styles of speedometers you may see on your HUD, a steampunk brass one or a modern one. If your HUD is for a sailboat, it will also have a blue triangle indicating the apparent speed of the wind. The example meters at left show a boat speed of around 18 knots and a wind of 22 knots. This meter reports in meters per second, knots or miles per hour. Click on the face of the meter to cycle between the three units.|
|These are two styles of tachometers you may see on your HUD, a modern and a steampunk style. Sailboats often don't have a motor and so will not need this meter. The example meters at left show about 1500 RPM, which is about 25% engine power. You can change the engine RPM with the page-up/down keys or a throttle slider on the HUD. The tachometer indicates a positive RPM for forward or reverse.|
At left are two compasses you may see on your HUD, a brass steam punk design and a modern one.
These are "needle compasses" where the background compass rose stands still and the needle rotates to show your boat direction.
If you are on a sailing boat, there will be a blue wind triangle to indicate the direction the apparent wind is coming from.
This blue triangle only appears when you are connected to a boat.
The two comasses at left both show the boat traveling WNW with wind coming from the NNE.
On the sailboat version, when you are in internal wind mode, clicking on the face of the compass sets the wind speed and direction.
Clicking near the center sets the windspeed to zero.
Clicking near the edge of the compass sets the wind speed to a little over 20 knots.
Clicking between the two sets a proportional wind speed between o and 20 knots.
The location of your click sets the direction, between the center and north selects a wind from the north.
The blue triangle shows the apparent wind, so if your boat is moving the arrow will usually not stay where you clicked. The apparent wind is the combination of the wind from the boat's motion and the external wind.
|This is the advanced navigation compass for sailing, which is available as an option on some sailboats. The outer ring is a "card compass" that rotates around the center needle which never moves. Imagine the needle to be your boat and the compass turns to always indicate the direction you are facing. A wind needle (blue triangle) indicates the direction the wind is coming from. This turns with the compass card so it indicates the direction that wind will flow across the boat needle in the middle. On either side of the wind needle are the "in irons bars" that show how close you can sail into the wind with your current speed, direction, and sheet setting. The bars move in and out as you adjust the trim of your sail. If the tip of the needle is inside the bars, you are sailing too close to the wind. The sails will flap, loose all lift, and the boat will slow down Either turn the boat untill the bow is outside the bars, or trim the sail until both bars are outside the needle. The NAV compass at left shows the boat traveling ESE with a wind from the north. The in-irons bars are far from the bow of the boat, you should release the sheets and sail faster!|
|Usually arranged underneith the NAV compass, these two guages show the wind speed and the boat speed. The example guages at left show a wind at about 17 knots and a boat speed of 12 knots. The wind speed is the apparent speed, which is the vector difference of the wind speed and the boat speed.|
|Only for boats that have an engine, this slider sets the speed of the engine. This directly causes the tachometer to change while the speed of the boat will increase a little later. You can also change the speed of the motor with the page-up/down (and in motorboats the fwd/back buttons). So you may not see this throttle in your HUD. The throttle can only change to one of 10 different speeds forward (the green part of the bar) and typically only 5 in reverse (the red part of the bar). Clicking on the border between green and red will stop the engine.|
This is a drop-down button that raises and lowers your fore and aft (F&A, FAA) sails. Click on it to see the 3 options.
Obviously a motorboat will not have this button.
-F&A sails are furled (dropped so they stop working).
-F&A sails are reefed (tied part way up so they catch less wind).
-F&A sails are raised all the way.
Furled sails do not pull the boat at all, reefed sails pull with half the force of the full sail. Fore and Aft sails are any sail that is typically held behind or along a mast, arranged close to the fore and aft line of the ship. These sails can pull you at an angle into the wind if trimmed correctly (using the FWD and BACK arrow keys). Sails of this type include Bermuda, Racing, Junk, Lug, Lanteen and Gaff sails.
This is a drop-down button that raises and lowers your jib sails. Cick on it to see the 3 options.
Obviously an motorboat will not have this button.
-Jibs and stay sails are furled (rolled up so they stop working).
-Jibs are reefed (rolled up part way to catch less wind).
-Jibs are opened up all the way.
Furled sails do not pull the boat at all, reefed sails pull with half the force of the full sail. Jibs are attached to wires, cables or stays at the front edge and are arranged close to the fore and aft line of the ship. Each of the different types of sails add a different ammount to the speed of the boat and the heel (tilting over) of the boat.
|This slider sets the trim of the for-and-aft and jib sails. Imagine that sliding this up causes the sheet (the rope connecting the boom or corner of the sail) to release. This allows the sail to swing farther out and catch more wind. (Unless the wind is coming from too close to the bow). Sliding the control down pulls the sheet in tighter causing the sail to swing in closer. This allows the boat to sail closer to the wind and travel into the wind (at an angle).|
This is a drop-down button that shows you three options for raising and lowering your spinnaker.
-The spinnaker is taken down and put away.
-Spinnaker is raised but loose.
-Spinnaker is tight and working, if the wind is right.
A spinnaker is a loose triangle of sail material that is raised up the mast on one corner and pulled down at the other two corners. If the boat is facing down-wind, a spinnaker will inflate like a parachute and pull the boat along. But if you turn just slightly off-wind, the spinnaker will collapse and generate no pull.
This is a drop-down button that will show you three options for raising and lowering your square sails.
-Square sails are furled (tied up so they stop working).
-Square sails are reefed (tied up part way to catch less wind).
-Square sails are opened up full.
Furled sails do not pull the boat at all, reefed sails pull with half the force of the full sail. Square sails hang from yardarms in front of a mast, and turn to face downwind (until they run into the rigging and cannot turn farther). These sails sails only work well when you are sailing with the wind.
- Clicking the moor button makes the boat stop where it is.
- Clicking the cast-off button allows the boat to sail again.
Mooring a boat gives you an opportunity to step off and explore, then continue your journey. This prevents the boat from returning to dock or deleting itself when the pilot unsits. When you moor a boat, the sails are all lowered and you have to raise them again with the HUD.
|This button causes the HUD to "hide", to shrink up and to the left into a single button. Once you have your course set and your sails trimmed, you can move the HUD out of the way with this button to free up more of your screen for the view.|
|The HUD shrinks down into this little green arrow when hidden. Pressing the greed button causes the HUD to stretch down and to the right back into the main navitgation page.|
|Pressing this button will bring up this WEB page in your browser to help you control your boat.|
|Pressing this button changes the HUD to a page of setting options for the boat.|
|The HUD has up to 5 pages of buttons, three of them are open for boat builders to add new functions. One possible use for one of these pages would be a color-change page that allows you to change the color of different parts of your boat. This icon is a suggestion for the button that would take you to a color change page.|
|A common use for an additional page in the HUD is a page to control cannons. This icon is a suggestion that might take you to the weapons page. I have built several examples of this, one for my Pirate Gunboat which only has one cannon. Here is a page describing the buttons that typically appear in a weapons HUD. A boat builder may change all the icons to different images. I also built an extensive weapons page in the HUD for the Golden Hind conversion that I did. That HUD has buttons to fire 16 different cannons individualy or in three different groups. This setup is done by editing the description strings of the buttons on the HUD and on the cannon. With my "Magic Cannon" you can set up almost any number of cannons on your boat without needing to write any scripts. The cannons, balls and mounts find each other based on the description strings in each prim.|
|Pressing this button will make the HUD exit, detaching itself from your screen.|
