Yes Jay, I believe the Blade uses the the exact same mast as the Taipan 4.9. The 4.9 was built just a couple inches narrower, long before there was an F16 rule, so I expect they will optimize the 4.9 hulls with the F16 measurements, and the update the sail plan with a self tacking jib, etc. OR, are they going to build completely new hulls, shaped like the Capricorn's? <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
