Before starting this article I think that the most important rule of them all is this one.
A boat and her owner shall compete in compliance with recognized principles of sportsmanship and fair play. A boat may be penalized under this rule only if it is clearly established that these principles have been violated. A disqualification under this rule shall not be excluded from the boat's series score. (RRS 2)
Transmitter aerial extremity shall be adequately protected (RRS E1.5)
You can buy one from most RC suppliers or use your creativity and find anything that will make the end of the aerial visible and safe (ie buy a Kinder egg and use the plastic inner egg as protective item)
We’ve all spent money and time to prepare our boat and the last thing we want is to see it damaged in a collision with another boat. So Avoid contact at all time.
A boat must avoid contact with another boat where ever possible. (RRS 14)
Be a “man” and take the penalty. Should you break any rule from the RRS 2001-2004 you should perform one of the following action :
A boat that may have broken a rule of Part 2 while racing may take a penalty at the time of the incident. After getting well clear of other boats as soon after the incident as possible, a boat takes a 720º Turns Penalty by promptly making two complete 360º turns (720º) in the same direction, including two tacks and two gybes. When a boat takes the penalty at or near the finishing line, she shall sail completely to the course side of the line before finishing. (RRS 44.1 & 2)
While racing a boat shall not touch a racing mark. Should a boat touch a racing mark , the boat must take a penalty by making on complete 360º turn including one tack and one gybe (RRS 31)
Probably the most known racing rule. But nevertheless we keep on seen boats / skippers braking this rule.
When boats are on opposite tacks, a port-tack (wind filling from left side of the boat) boat shall keep clear of a starboard-tack (wind filling from the right side of the boat) boat. (RRS 10)
When boats are on the same tack and overlapped (one boat’s bow engaged on the stern of another boat), a windward boat shall keep clear of a leeward boat. (RRS 11)
