| RI-02-11 ZINC REQUIREMENT (2002-02-12) |
|
| Q1: | Is it permissible to remove the zinc on the propeller shaft? |
| A1: | Zincs are not part of the boat’s standard specifications published by JBoats. However, zincs have been installed by TPI on all new boats since 1991. They are essential in preventing electrolytic damage to the prop. Rule 1.1 states that the class rules are there to preserve the J/105’s “equality of performance” and Rule 1.2 states in relevant part that “J/105s shall be alike in …. equipment ….” In light of these considerations, all boats must have zincs for class racing. It is permissible to use “low drag” zincs, however, and the accidental loss of a zinc is not a grounds for protest unless the loss was discovered before racing. |
