Can't speak for anyone else, but as I get older (I am a very fit 56) my tolerence for things like lugging around a 400lb boat has passed, especially when a much lighter weight alternative exists with the added benefit of a lower cost.

As all of us baby boomers get older, weght of the platform will become more of an issue. The weight minimum that Macca and his associates fight to increase is one of the major draws of the F16, one that can pull sailors and would be sailors from other active and dead one design and formula classes who refuse to abandon outdated excessive minimum weights.
