may be replaced. The engine can be re-built. The underwater unit may be replaced. All subject to official inspection and official authorization before any
attempt is made on replacement or repairs.
The hull, engine or any part thereof that is damaged beyond repair cannot be replaced during the actual heat be ing raced Exceptions: An irreparable hull can
only be replaced by another if the OOD decides another competitor was responsible for the damage caused only during a race or training on the water. Any
damaged part of the engine can be replaced with similar except the cylinder block. Underwater units that are damaged beyond repair can be changed provided
they have the same gear ratio and from a similar homologated engine.
All changes must be sanctioned and supervised by the Scrutineer or an appointed official. All damaged parts including hulls must be kept in a secure place for
any official inspection or pending possible protests. Any equipment subsequently found to be repairable will result in the driver being eliminated from the
complete event. All costs pertaining to the stripping of additional equipment will be the responsibility of the competitor in question. A fee, as specified in the
advance programme, must be paid to cover the inspection of any protested engines or equipment. These charges should be reason able. When different
disciplines are held on different days and no fully secure compound is available either overnight or days then all boats must be re-scrutineered before racing re-
commences. Failures will result in the loss of all previously gained points.
