Ride - [reply to inquiry by Alex on Carrera after the March 2000
Possession Point race in Seattle]
Alex,
Great story! Sometimes I think all Olson 30 people are not
only crazy, but too blase about the way the boat sails --
this was a day that, for us, gave the most fun I can imagine
out of racing a sailboat. You can't get more fun out of
sailing than racing an Olson 30 in heavy air.
You did very well in this nasty situation. The last time
we crashed, Feb 98, the roundup put the mast under water
almost to the top spreaders, and the torque threw 4 people
into the air over the lifelines (I threw the mainsheet to
one trimmer in midair) and bent the stanchion I grabbed
on high side to a 75 degree angle. The beer flew out of
the cooler and smashed against the underside of the deck.
Fortunately, we had just crossed the finish line and were
near home.
A few comments -- others who are better at this sort of
sailing will have better advice.
- Aliens tends to leave the #3 up downwind in very heavy
air. I think it helps stabilize the flow, and prevents
wraps, and especially on short courses one doesn't have
to deal with the weight forward to hoist it again. (We
did take our #3 down this race, though.)
- When the boat is way overpowered in big waves, the way
I chicken out is to sail higher (maybe 160). The pole
is overtrimmed when we sail high and undertrimmed when
we sail low. The higher angle stabilizes the rolling
from the waves. The chute is twinged down both sides
to minimize oscillations (from waves and from the Karman
vortex trails). Then when we get planing at the higher
angle I can bear off into the wave faces ahead with
apparent wind more forward for the compass course than
if we were not planing. I will be faster when I learn
to sail more DDW in these conditions. Slightly by the
lee can be fast but is scary. Weight trim on the boat
is key. We had constant lee helm problems this race
which kept making me sail high when the pole tip headed
for the water to keep the boat upright. We had one or
two crew on the transom hiking the high corners but
this was not enough; the helm improved only when we
put another 200lber on the lee rail midships, plus trimmed
in the main a bit for more mainsail power. For the lee
helm, I should have powered up the main more. This race,
I learned that pumping the main when the boom points
skyward helps lever the boat back flat.
- Driving the wave faces in front of the boat is also
key; we did ok at this -- trying to head up just enough
to bump over the wave ahead so we could go over it and
surf it down. If you can get it planing, the waves are
just obstacles.
- The driver is at the mercy of the trimmers. At the first
sign of a roundup crank the pole back, ease the sheet;
at the first sign of a round-down, ease the pole quickly
about 2 feet forward. This rotates the chute so the
forces tend to flatten the boat. The rudder is not enough.
Another easy rule we use: "wet side eases." The trimmer
who is heading for the water eases.
- Once again, we learned to foot upwind in heavy air.
Crime Scene remembered this late in the final beat and
powered over us, sheets well eased and sails well twisted.
The slot opens, the main works, the boat levels, and
it speeds. I saw their trim, I thought, "Duh!", imitated
them and sped after them. Having the main flat and travelled
down to the stopper is not enough, you have to ease
the jib sheets or put the lead way back or put the lead
outboard or some combination of these for the conditions.
