Our association called the Offshore Racing Association administered the Offshore Racing Rule. This rule predicts relative time allowances between boats. It permits boats of various types, ages, and sizes to compete with the fairest ratings possible.
The Offshore Racing Rule is an objective rule. Ratings are based on full measurement of all the speed related features of your sailboat as well as a Velocity Prediction Program. That program calculates the speed potential of each boat at any combination of wind speed as well as course direction. This program is a set of algorithms. It was developed through systematic research and uses fundamental scientific methods.
Know The Rules
This rule is intended to rate properly prepared and designed boats that are equipped for offshore racing. There is one thing we would like everyone who uses this Offshore Racing Rule to understand is that it is not a development rule. It is not intended for people who are looking to try to beat the rule. The Velocity Prediction Program algorithms are non-public just in case there are any attempts to try design boats to the rule. We update the algorithms on a regular basis to stay one step ahead.
Our rulebook provides various details. Those details include ratings, restrictions, measurement, and everything else that is required to race your boat under the Offshore Racing Rule. So if you decide to race, you should consult the rulebook to prepare and race your boat. Here is an overview of the rules to help you understand what you need to do to race under the Offshore Racing Rule.
Scope of Rule
The Offshore Racing Rule is intentded to rate a broad diversity of sailboats, but there are some limits. This is to ensure reasonable close racing. At this point and time, our association does not rate kite sails or multi-hull boats.
There are valid racing certificates required to race under the Offshore Racing Rule. Boat information is processed and collected and valid certificates are issued.
- Getting Started
A full description of the geometry of the sails, rig, and hull are required as well as the stability of the boat which means the resistance of heeling over. The description should also include how the boat sits in the water to get the wetted area, weight, and length, etc.
You should contact the US Offshore. They will provide all the necessary information that you need. A trained and certified measurer will be needed for your geographic area. You should familiarize yourself with the guide. After that, contact the measurer to start the measurement process.
- Hull Measurement Ashore
You are responsible for getting your boat ready for measurement ashore.
- Measurement Afloat
You are also responsible for getting your boat ready for measurement afloat.
- Rig and Sail Measurement
You are responsible for telling the measurer about all spars and sails that he proposes to carry on the boat. You need to make them available to measure.
- Configuration Changes
If there are any changes to the equipment carried on board and/or the sails, rig, the appendages, or anything that may change your boat’s rating, you are responsible to declare those changes to whoever is in charge of rating authority.
- Stability Requirements
Stability Index or Capsize Screeen may restrict your participation in races. Boats with movable ballast may be restricted as well based on the Ballast Leeward Recovery index.
- Restrictions While Racing
Here are a few examples:
- * Use of stored energy in ways other than those explicitly permitted
- * Changes made in fuel and water tankage beyond normal use
- * Running the engine for propulsion
- * Movement of fixtures, accommodation, and ballast
- * Changes to standing rigging
- * Trim and use of sail not being consistent with how they were rated and measured initially
- * Changing the location of the mast step
- * Rotating masts
- Measurement Types
A fully measured boat is referred to as full measurement. There are two more types of measurements called a partial measurement and measurer verified.
