Race Rules:
------------
1) We race on the honor system. Please don't cheat.
2) Only the Race Versions of the Flying Tako 2.1 Racing (at the time of writing) are allowed in the race. This means no Practice Versions or Motor Takos.
3) Racers may position their boats in the staging area by any means prior to the start of the countdown.
4) Racers may not drag their boats at any time once the countdown has started or during the race. For that matter, racers can't de-rez and re-rez their boats farther down the course.
5) Racers who left-click or right-click other boats after the countdown has started WILL be disqualified. If you have a passenger in your boat, you are accountable for their actions in this regard, and may be disqualified.
6) Racers must make every effort to avoid ramming other boats or forcing them off the course.
7) Sometimes glitches in the start line/lap counter do occur, and the race host may have to correct erroneous results.

The race host has the final say in disputes except in cases where they are the subject of a disputer right of way protest.
9) Local rules may apply, for example a two boat length 'no mooring zone' before the start line or similar. These will be explained with each regatta, ideally in the event description.
Right of Way rules when sailing.
SLSF is going to try these rules for a short period to see how well they work when racing in Second Life. They will ONLY apply to races where there is a windsetter in operation. SL wind is so variable it is almost impossible to apply these rules to 'natural' wind and certainly impossible to revisit the incident after the race.
There are four rules, the first two will apply to all races, the other two to A Fleet races for experienced skippers.
After a period of three regattas using these rules we will have a large meeting to consider implementing, ammending etc. these rules for racing in SL.
I will state the four rules baldly, then explain them.
10) When on opposite tacks the boat on the port tack shall keep clear of the boat on the starboard tack.
11) When on the same tack and overlapped the boat to windward shall keep clear of the boat to leeward.
12) When on the same tack and NOT overlapped the boat astern shall keep clear of the boat ahead.
13) While tacking a boat that passes head to wind shall keep clear of all other boats until she is on a close hauled course.
Penalties:
At the moment a boat that believes any rule has been violated must shout protest. This is done by shouting (cntl+enter) "P" and the name of the person you are protesting again e.g. "P Eloise". If the other boat agrees they reply with "Yes" and must sail a 360 (turn right round) before rounding the next mark or crossing the line. They must do this in a fashion that does not impede any other boat's path - if they do then they can be protested again.
If they reject the protest they shout "No" and keep sailing. A panel shall be convened of those neutrals available to consider the case (this may be other skippers in the race, or experienced sailors watching or an observer or similar depending on the regatta). If the protest is upheld the captain of that vessel is given penalty points equal to the number of boats racing plus 2. Their finish position points are not added to this, but their finish position is recorded for other racer's points.
Explanations:
Keep clear requires you give YOURSELF time to respond to a sailing manoeuvre that the boat you are keeping clear of makes with reasonable time and seamanship.
Rule 10:
A port tack means the wind is coming from your port side. Starboard tack is the opposite. In the Flying Tako the helmsperson sits on the starboard side. If the sail is on the same side as you, you are on a port tack. Anyone with their sail on the opposite side to them is on a starboard tack, and you've got to keep clear of them, give them space to manoeuvre.
If the boat on the starboard tack changes course because they believe you would hit them then you have violated this rule. If you both stay still and there is no contact, however close you get this rule was not violated.
If the wind shifts and the boat on the starboard tack wishes to change course to take advantage they cannot steer into the boat on the port tack, they must give it reasonable room to keep clear of them in this case.
[Given the visual limitations of sailing the Tako sailing into someone when they're on a port tack and you're on a starboard tack and they could not reasonably see you and adjust course will not be a violation of this rule, you must give them room to keep clear.]
Rule 11:
Same tack and overlapped means you are actively overtaking the other boat. For pedantic types it means that part of a line parallel to the sea surface (easy in SL) and perpendincular to your centreline and either from your bow or your stern would pass through the other boat. The windward boat is the boat closer to the wind - in practise this means your pennant points towards their boat, or the side of your boat that they are on.
Again the boat with right of way must give the other boat room to keep clear, so you can't repeatedly turn into them and chase them off for example.
This rule clearly and explicitly applies to 'undertaking' (i.e. overhauling a boat from astern and passing to leeward of it). However if you are close (within two hull lengths) after the transition from sailing astern to sailing overlapped and to leeward you cannot force the boat to windward off course AND you must allow them room to keep clear - i.e. a reasonable period of adjustment to your presence and course. You can adjust to sail a proper course but no further. A proper course is the optimal racing course if the other boat was not there, so straight to the next buoy for example.
With lag, no peripheral vision etc. this rule may prove hard to apply, make sure you keep well clear.
These two rules will apply to all regatta races. The following rules may be introduced by request and will apply to A-Fleet races at the moment.
Rule 12:
This applies ONLY if you are on the same tack, i.e. wind from port or starboard for both. This CAN'T happen if you're sailing in opposite directions so the rule does make sense.
If you are behind them give them room. If you are good enough to overhaul them you must still give them room to keep clear as you draw level - that is most commonly taken as if you overhaul them and are within two hull lengths of them at this time. Sailing into someone's leeward stern as you catch them and claiming they violated rule 11 is wrong under rule 11 and a penalty under rule 12.
Rule 13:
If the wind is within 35 degrees of ahead of you for ANY reason (including the shift of winds) you must keep clear of other boats around you until you could sail a close hauled course (35 degrees) again. If your sails aren't close hauled but could be then you are assumed to be sailing a close hauled course for this rule. Whilst you are in that situation and Rule 13 applies then rules 10-12 do not apply.
(NB for those of you that want to read these rules elsewhere e.g.
http://www.racingrules.org/guide/guide07.htm they are also rules 10-13 in RL sailing.)

If you don't understand these rules feel free to ask me. There will be a 45 minute clinic on rules 10 and 11 before the regatta on Sunday where we will demonstrate these rules and what they mean.
