Mark,

Bravo! Wow...that was quite complete and very accurate. It should be noted that when the NAF18 class rules were first published, not only was the measurement method different, but the stipulated overall platform weight was less than the International F18 rule...which had the appearance of leaning toward one particular manufacturer. That is certainly not the case now and all NAF18 rules align with the International rules except for a couple of very minor exceptions (compass requirement, paddle, etc.)

P.S. It's Mike Krantz and/or Dave Lennard.
