Why don't you represent the NA F16 class (don't know if you are a committee member or not) and organise a Formula event inviting the all other formula classes F16, F18, (F20 and F17 even if they are not true F classes)

If you can sell the event as a must do on the calender, then sailors will come. If you can not, then it will be a flop.

You could even create a new mix class event inviting all and stick the F16s and F18s on the same course/start and race first across the line. Once again, if it is appealing to sailors, then they will come. If it does not, they won't

If you have a desire, then organise it. Don't expect others to do it for you.
