Hi Richard,
Your observations are good.
These comments are from a table in Skeene's Elements of Yacht Design
discussing effects of IOR:
Snub stern: general effects - reduces weight in end giving small trim
forward and may give boat unbalanced look. Effect on rating - no
change to slightly lower. Effect on speed - weight saved in ends
should make hobby-horsing less and give sails a better "platform" to
operate from with very small increase in speed & comfort.
While not really a snub stern, the benefits are the similar and the
C&C stern is wider for more "power" capacity. I recall there being a
deck length measure in IOR that also favours a reverse transom but I
cannot be sure.
Anyhow, wheel steering was much favoured especially for yachts that
would also be cruised. The reverse transom got a skipper behind the
wheel pushed forward and can be a significant weight distribution
forward, if ya know what I mean :)
Cheers, Russ
Sweet, 35 mk-1... An early IOR yacht that is more similar to
the CCA rating influence than IOR.

This is January armchair stuff I confess, but I have always wondered
about the way different boat lengths are listed; I know there has
been some discussion about the 37+ which is actually 40 overall; but
what really got me wondering was this fall when the local boats were
hauled and set on cradles for the winter, my 33-2 was placed right
next to a S2 30 of about the same vintage; the rigs were identical,
the boats looks very similar on deck, and ths sail area is about the
same; (of course the under body of the hull designs were different);
but what stood out to me was that the boats were nearly the same
except for the reverse stern on the C&C; my theory is that C&C put
the extra length on the stern so that when heeled, the boat will
have added waterline length and hence be faster; (and they were also
designing to maximize the benefits under a rating rule). On the
other hand, for day-to-day all around usage it seems that the C&C is
a 30 ft boat with 3 extra feet of transom. When I look at the other
C&C designs from the same era I see the same trend. I compared
the total sail and displacement of several 35 foot boats to the same
stats for s 1986 C&C 38-3 and the numbers, while not identical, were
surprisingly similar...
[Caveat; I am not denigrating any of the boats and absolutely love
the C&C designs, I'm on my 3rd ( 25, 29 and current 33-2) and
looking a possibly no. 4]
Does anyone else see the comparisons or am I just getting cabin
fever... pun intended...
many thanks.
