Re: S2 7.9
Other than the newer various sport boats (Melges etc) something like the S2 is likely going to be a good decent performing trailerable, esp since shallow launching is a priority.
Haven't sailed one but have raced against one.. It went very well. Certainly this would be a better sailing boat than any of the crop of water ballasted trailerables.
Not sure how much weight is in the daggerboard/lift keel..
