SCUTTLEBUTT #203 -- October 20, 1998
WILL IT BE IR2000? -- A guest editorial by Bob Johnstone
Small incremental tinkering with the IMS VPP has not gone far enough, fast
enough. Consequently, any rule based upon the current IMS VPP program such
as AMERICAP or the ORC Club Rule is not likely to work. The IMS rule is
more akin to a class measurement rule such as the International 12-meter
rule than any handicapping system because of its type-forming result. If
your boat doesn't look like an IMS boat, it won't be rated fairly as an IMS
boat.
The J/125 IMS Rating (WINGS OF THE WIND) compared to a Farr 40 IMS Rating
(HISSAR) highlights the problem. PHRF's life-size test tank, empirical
conclusion after some 40 races this past summer shows the J/125 to be 6-9
seconds per mile faster than the Farr 40...NOT 46 SECONDS per mile as
indicated by IMS.
Some might say that's the asymmetric spinnaker. Not so. Check out the
following (J125/Farr40) ratings. IMS must think the J/125 planes upwind.
>Beat VMG at 12 knots (630/687)
>Beat VMG at 20 knots (590/666)
>135 Degree Reach at 12 knots (371/424)
>135 Degree Reach at 20 knots (274/315)
>Run VMG at 12 knots (493/537)
>Run VMG at 20 knots (470/531)
If IR2000 comes close to CHS history of providing "sprit boats" a fair
chance to win (the J/90 won the Britannia Cup in Class 1 CHS at Cowes
Week), then maybe that solution will be forthcoming soon from Richard
Matthews and his team on IR2000 in the UK. Far better to shape the CHS
adjusted reality into a formula than doing the reverse. If IMS can't
start with being as good as PHRF in handicapping different types of boats
around the world, then all the dynamic scoring, etc. is only to the benefit
of a few willing to buy IMS class race boats.
From the J/125 and Farr 40 comparison it seems that IMS rule has a built in
bias against stability, particularly in a narrow, light boat. And, it's
quite something to imagine that these two race boats differing in overall
length 5" and not at all in sailing length (the Farr has a more plumb bow)
would be separated by a magnitude of approximately 7 IOR feet! So, there's
something desperately wrong with the effective sailing length formula.
Here are the numbers: J/125 first mentioned then Farr 40 to the nearest 10th.
| J/105 | FARR 40 |
LOA | 41.1 | 40.7 |
IMS L | 39.0 | 37.3 |
BMAX | 10.5 | 13.0 |
B | 8.4 | 9.7 |
GPH | 512 | 558 |
Stability Index | 143 | 128 |
Draft | 8.1 | 8.5 |
Stability Ratio | 12.5 | 5.6 |
RMC | 1188 | 1237 |
DSPS | 11557 | 13217 |
SA | 891 | 1106 |
Spinnaker Area | 2157 | 1379* |
* J/125 spinnaker measures 170 square meters (1829 sq. ft.) under the
America's Cup Rule.
The above dilemma is put forth in hopes that Tom Leweck's Scuttlebutt might
serve as an effective platform for initiating reform. After all, if you
only need half the crew with more stability, then there'd be twice as many
boats sailing and twice as many boats built! Can't figure out why the
designers on the ITC and IMS Committees hadn't figured that out yet. -- Bob
Johnstone
Curmudgeon's comments: Although Bob's comments come close to bordering on a
J/Boat advertisement, he raises a number of interesting points about
measurement handicapping systems. OK 'Butt-heads, what do you think?
MORE HANDICAP RACING
The designers and builders of the new Champagne Mumm Admiral's Cup
mid-range boat, the Sydney 40, have decided that the class will now be IMS
Rule optimized as a standard. Four existing boats, including Ron Jones'
Sledgehammer (hull No. 1), will be bumped to reduce the IMS rating. The
hull molds at the builders, Bashford International, will also be modified
so that all future production yachts come out with the same IMS fea- tures.
"Originally we created a one-design that didn't completely en- compass the
IMS Rule," said Andy Dovell of the design company, Murray, Burns and
Dovell. "We didn't see IMS optimisation as being crucial to the success of
the boat in its role as the new 40-foot class for next year's Admiral's
Cup. "The market place is now telling us otherwise. Fortunately for all
concerned the opportunity was still there for us to optimise the existing
boats and the molds," said Dovell. -- Rob Mundle, Grand Prix Sailor

BERMUDA GOLD CUP
Four teams have advanced from the Qualifying rounds to the Championship
Round at the end of today's racing in the 50th edition of the Bermuda Gold
Cup. Racing was postponed in the afternoon because of no wind, therefore
delaying the outcome of Group 1 racing.
In Group 2, the teams that qualified for the first round of the
Championship beginning on Wednesday were headed by Murray Jones (5-2) of
New Zealand, Andy Beadsworth (5-2) from Great Britain, Andy Green (4-3)
from Great Britain, and Bermudian Glenn Astwood (4-3). The biggest
surprise of the day was the elimination of American Paul Cayard, winner of
the recent Whitbread Round the World Race and four-time America's Cup
competitor, who finished with a 4-3 record, but was sent home on a
tie-break countback. Other Group 2 results were: American David Whelan
(3-4), Swede Marten Hedlund (2-5), and Glen Foster of the USA (1-7).
When dawn broke this morning there was not a whisper of air across
picturesque Hamilton Harbour, and very little evidence of any wind
throughout the day. However, the race committee was able to get three
flights in during the morning, enough to complete the round. The final
four flights of Group 1 are scheduled for tomorrow, weather conditions
permitting.
Match ups in the Championship Round settled today are Jones versus seventh
seed Neville Wittey of Australia, Beadsworth against sixth seed German
Markus Wieser, Green meets Virgin Islander Peter Holmberg who is seeded
three, and Astwood goes up against Briton Chris Law, seeded two. Gay Larsen

EVERYWHERE
They are absolutely everywhere. They're in Norway, Spain, the UK and
Canada. There are two each in Japan, Australia and Mexico. Italy has three
and there are 10 in the USA. San Francisco even has one now. And every one
of these Ullman sail lofts will give an email quote on a new sail to show
you just how affordable improved performance can be for your boats

LETTERS TO THE CURMUDGEON
>> From Mike Ingham -- I am on the ugly (financially), but rewarding
Olympic trail in Tornados. I and many of my friends are having a hard time
getting insurance over seas. Insurance is not only a good idea, but is
required at most major events. Maybe some of your readers have some
insight. -- mikeingham@compuserve.com

RECORD RUN
Mari-Cha III, heading for the Trans Atlantic Speed Record, is flying. The
heavy winds are there and pushing them in the right direction. Sailing on
rhumb line to Lizard Point. At 09:45 UTC Monday they have 1.620 Nm to go.
Just after sunset the wind start to build up to 47 knots. During the last
night, Lione's choice was to sail conservative with speed and safety in mind.
Dropping mizzen, 3 reefs in the main and working jib. The night was
impressing with huge waves and gusts. It is wet, wet, wet everywhere. Trim
and ease is a must. Every second, every minute. For the first time the
interior is a nightmare. Never can you rest in your mind because at any
second you can be called on deck. The boat and crew are in perfect
condition and coming closer the Phocea record of 8 days and 3 hours. But
don't force your luck. MC-3's position Boat speed 22 kts (surfing at >30
knots). Wind speed 40-45 knots.

AMERICA'S CUP
(The following is an excerpt from New Zealand's DEFENCE 2000 - ISSUE NO. 73)
Fast 2000's America's Cup training boat is now on its way to Auckland from
Lake Geneva in Switzerland where the Swiss crew has been exercising over
past weeks. Crew selection has been in progress during this period and
those who make it can expect some intense training from skipper Marc Pajot
in Auckland, December thru March 1999. Pajot says he is looking forward to
some "great practising" with other challenging teams.
Meanwhile, the Swiss R&D team have completed a number of major steps in
their development plan with members extremely excited about some of their
results.Construction on the Swiss made yacht will start in Frebruary 1999,
allowing the syndicate to take maximum advantage of their current research.
Aloha Racing's decision to rescind the agreement to purchase the compound
of oneAustralia, has been based on the premise that it would better to have
this money spent building a second boat. (The oneAustralia's inventory has
subsequently been sold to the Cayard syndicate). John Kolius has revealed
that he felt a second boat was more important to their challenge than the
purchase of oneAustralia's assets. This Hawaiian syndicate has this week
revealed that they plan to employ 22 builders on their two yachts which
will now, not be ready until mid -June 1999. This will give their sailors
less than three months of training. The syndicate news release goes on to
say that no other team (Team New Zealand included) has tested as many
models as Aloha and they believe that the other American teams are well
behind in the progress stakes as they now stand. -- John Roake

AROUND ALONE
Everyone expected Class II of Around Alone to be a two-man boat race, but
few expected that it would be Brad Van Liew, not Mike Garside, challenging
J.P. Mouligne for the top spot. At this morning's 0944 GMT update, Van Liew
was enjoying his fifth consecutive morning at the head of the small-boat
fleet. With 3,206 miles to go in the Distance to Finish column he was seven
miles ahead of Mouligne and, finally, safely south of the Brazilian bulge.
On the morning Van Liew took over the lead, Garside was in second place by
a slim eight miles. But then the hydraulic pump for his swing keel took a
powder and life has gone from intense to intolerable. This morning he was
in third place, some 154 miles behind Van Liew. With the keel still a
liability, there is no reason to believe he will regain those lost miles
anytime soon. -- Herb McCormick

AND THE WINNER IS
Only three of the entries to pick the top five finishers at the St Francis
YC's Master's Invitational Regatta (OFR) correctly identified three of
those skippers. Following are copies of their entries with the actual
finishing place in parenthesis:
Jeff Madrigali submitted:
1. Don Trask (3)
2. Roy Dickson (2)
3. Pelle Petterson (10)
4. Bruce Munro (4)
5. Tak Takamura(14)
Kent Pierce picked:
1. Roy Dickson (2)
2. Lowell North (6)
3. Dick Deaver (1)
4. Don Trask (3)
5. Malin Burnham (9)
Kent's entry had all of the top three finishers and his two "bad picks"
both finished in single digits. Even though Madro actually picked two of
the top five in the spot in which they actually finished, he overlooked the
regatta winner completely and his two "bad picks" were both in double
digits. So, after carefully weighing all of this, the judges have declared
Kent Pierce the winner of the official Scuttlebutt shirt generously donated
by Frank Whitton at Pacific Embroidery.
THE CURMUDGEON'S OBSERVATION
When running a racing program, it's not the people who you fire who make
your life miserable -- it's the people you don't fire.
