Top notch repair work! I'm in the process of similar things to get my TheMightyHobie18 race-ready for the NCC 100, some of these tips will come in handy. Looks like my top competition will be Krantz on the F20c, somehow I doubt my asym'd TheMightyHobie18 will keep up...
Your discovery of the void in the daggerboard area, along with some recently acquired information (lack of Nacra parts availability) is making me lean towards Hobie or AHPC for my F18 buying needs. Granted, this same thing could happen on any of the platforms if the builder isn't checking quality very well.
I don't know a whole lot about it - but apparently part of the motivation behind the last iteration of the Infusion was to change how they join the hulls and daggerboard trunk....making it more like Hobie and AHPC were assembling their boats and removing the need to do so much cosmetic refinishing after bonding the hull halves. I'm sure the way the daggerboard trunk is bonded is made better.
Still, though, this kind of thing is frustrating to have to do to a boat that's not yet 2 years old. Although I did more than just repair that trunk, we've probably got 35-40 hours in the work so far and the trunk was at least 2/3 of that.
