VARIATIONS FROM BASE RIG, LISTED CONFIGURATIONS AND ALLOWANCES |
||||
|
Where a cruiser does not conform to Base Rig for its class or type, allowances up to the following maxima may be applied on a trial basis: |
||||
|
Boat with all headsails smaller than Base Rig (+40) |
||||
|
Boat with no spinnaker (+40) |
||||
|
Boat with mainsail other than Bermudan (+20) |
||||
|
Boat with cruising chute and no spinnaker (+20) |
||||
|
Boat with all spinnakers smaller than Base Rig (+20) |
||||
|
|
||||
|
Any variation from Base Rig not covered by the above list, such as hightech sailcloth, may justify an allowance (excluding Crew Skill Factor). If it is considered that the above allowances should be different, clubs should decide on a suitable number and, if of general application, inform the RYA. |

In some cases the same class of cruiser will have more than one published Number relating to different configurations of engine/propeller and/or keel. In such cases the published Number should be used in preference to the use of allowances. |
|
For boats other than cruisers, the above allowances may not be applicable or suitable. For a dinghy without a spinnaker, for example, an allowance of +20 may be suitable. |
|
Should an Owner decide to race his boat to anything other than Base Rig, he should declare the difference to the club and the club should allocate a Trial Number for the boat. In such cases the boat shall not change from its declared state during a series of races. If no difference is declared the club should apply the lowest Number applicable for the class during a series of races. |
