As a guy who has flown thick airfoil ships and currrently owns a ship
with a 17% airfoil, I am curious what kind of performance in climb I
might see with a 14% airfoil section.

If you are talking about the Wortman FX67-K170: The FX 62-K131 of the
ASW-20 from the same era climbs at least as well as the former.

The very thin airfoils of current gliders (e.g. ASW-27) climb like
homesick angels.
