I use the North rake number or even a bit more. In my opinion you
definitely need a toggle or a longer forestay. Also, you need a #1
genoa that is fuller than the ones made for San Francisco. And you
want plenty of headstay sag upwind and less jib halyard tension in
light and medium air. The main should be built relatively flat,
because if you try to flatten a full main with the backstay adjuster
you also tighten up the headstay too much and depower the genoa.
Everyone in our fleet and most of the boats in San Francisco use
flat, loose-footed mains.
We sail on Lake St. Clair which usually has medium-light air and a
steep chop due to the shallowness of the lake (6-15 ft.) Going upwind
into a chop or big waves is the most difficult condition for the E27.
Former dinghy sailors do it best. Our base PHRF rating is 144 with a
six second pole penalty for one design. That is, we race with a 138
one design rating, and boats from our class manage to do okay in
PHRF, especially when there is a big breeze for distance races and
when the wind is light and the water smooth. A couple of very good
Snipe sailors sailed my boat to a PHRF first out of 50-60 boats in
40-mile race in medium breeze and fairly flat water. They said they
played the backstay quite a bit to keep the boat on its feet.
We had to battle to get our rating up to 138 because our PHRF
committee initially looked at the San Francisco Bay rating which as I
recall was 126 at the time our fleet was formed. After five years or
so experience we spent nearly an entire winter once a week at PHRF
meetings lobbying for an increase from 132 to 138. We made our case
by comparing with the J30 Detroit rating of 141, as I recall and with
some unfavorable comparisons with S2 7.9s and Santana 35s. Most of
our racing is one design, but we sail PHRF in some week night beer
can races. Some of them are double handed main and jib races. This
year we successfully got a 144 rating for these races on the theory
that why should we have to pay a 6-second spinnaker pole penalty when
we weren't using spinnakers?
Crew weight is critical when there is any kind of a breeze. Before
the class limit of 880 was established the top boats in San Francisco
sailed with 1000-1100 pounds. With enough weight on the rail the boat
goes upwind like Gangbusters. I think Ruby My Dear had over 1000
pounds last year at Key West (third in class).
Finally, it helps a lot to rock the mast forward downwind. To do this
you need in line lowers so you can ease the aft lowers way off
(before the start only) and rock the mast forward by attaching the
jib halyard to the stem and cranking on the halyard winch.
Excuse me for going on so long about stuff you probably already know!
And good luck! You got yourself a great boat! Why not bring it up to
the Detroit NOOD next June?
