9. OPTIONAL EQUIPMENT

It is rather difficult to draw up a set of rules regarding optional equipment This is one area where the boat owner is free to do anything he likes to his boat. In this way each boat takes on its own character. The intention of this clause is to allow each owner free expression regarding his boat but this should not be used to give one boat an unfair advantage over another.

In general if a boat is made heavier by the addition of a piece of equipment then it should be allowed.
If a boat is made slower by an additional piece of equipment it should be allowed.
If the additional equipment makes no difference in speed it should be allowed.
Any boat owner in doubt about any additional equipment should approach the committee The decision of the committee will
be final.
