I can tell you all from private experience that the Hobie name doesn't give the FX-one and Tiger more resistance to denting.
I'm sure that H16 and P16 and other full glass don't dent but than again the only way these boats can arrive in the top places is by handicap corrections. That is what happened at Texel. The boat itself came in some 25 minutes behind the leader, but it corrected out to a top 10 placing. Any rating system that is any good would do that as it aims to make the crew ability independent of the boat design (speed)
Lets face it all new boats are foam core and all new boats suffer from denting; no exeption and totally independent wether they are called Nacra, Hobie or Bimare.
