The light air handicap for the 35s5 is much greater, percentage wise than
the handicap for the Catalina 27.

What do you think causes the 35s5 to fall off so sharply in light air? Is it
the semi planing hull form that does poorly in light air displacement mode?
Semi planing hulls are known to be unstable when pushed to high speeds and
now they are bad performers under light air? Who would buy a boat with such
a narrow range of performance? Why is it so difficult to get it to perform?

Amen!

I was looking for VPP's and Polars and ran into this:

This shows how ratings should be adjusted for light and heavy air,
using the new Americap system. PHRF is assumed accurate at 11 knots,
and adjustments calculated for 6 and 20 knots are shown in the last
columns. The two examples explained are an Alberg 35, which needs a
big boost in light air and a reduced handicap in heavy, while the
J-125 is the opposite, deserving less handicap in light and more in heavy.

For the 35s5, a large 24 sec/mile additional handicap is needed to
help it keep up with the fleet in light air, while it only out
performs by 7 seconds in heavy. Perhaps this wasn't the best choice
for light air.
