Report Boat Modifications from Stock
If your boat has been modified from its original (stock) configuration in any of the following ways, you must report these updates. Some modifications may require measurements or additional documentation.
(Note: This is not an exhaustive list—report any change that could affect performance.)
- Mast replacement or modification
- Engine replacement
- Keel or rudder changes or modifications
- Replacement of batteries or other heavy components
- Addition or removal of powered systems
- Sail configuration changes (e.g., removal of spinnaker pole)
- Rig configuration changes (e.g., removal/addition of headsail furler)
- Rigging material changes (e.g., stainless steel rod/wire to synthetic)
- Removal or replacement of heavy or structural items (e.g., bunks, bulkheads, cabinetry)
Important: If your boat differs in any way from the manufacturer’s original specifications, select “Yes” to the following question and record all relevant modifications.
Failure to declare changes to the US Sailing Rating Office may result in immediate invalidation of your rating certificate and can be grounds for disqualification from a race or regatta.
