I agree that based on Dave's description of his sailing needs the F16 fits the profile.
But I think it's a little presumptuous to state there is only one boat that fits his profile. It definitly narrows it down a lot I'll give that. Finding the boat in his price range might be the ultimate determiner.
There'll be pros and cons to most of the boats he'll be looking into now. Most will fit his needs just fine, but have strengths that only Dave will be able to sort out.
