Bit pushed for time (Seminar starts tomorrow, followed by Wave Nationals), but basically the idea behind NAMSA is to get all the organizations under one, united umbrella. When organizations join NAMSA, there would be key people from all of them that would give us the blood I have been referring to.
Individuals that do not belong to any organization have been accounted for as well and joining would be encouraged by those sailors.
But, imagine if CRAW, CRAM, CRAC, CABB, et al joined hands and worked together, it would a chorus of strong voices. Strong enough that NAMSA would definitely have an audience. US Sailing and ISAF would have to listen.
