BOAT EQUIPMENT AND SAIL REPORT FROM EUROPE
by Chris Chatain
The boats: At Naples there were only 3 or 4 fiberglass boats; the
top 10 were all wood. Wooden FOs are simply much easier to get in Europe.
Also, though people are willing to invest money on experimental sails, most
would prefer to start with
a proven product for the basic hull, i. e., a Bob Hoare. There were also
many boats from the German builder Hein, which were certainly as pretty
as the Hoare. Reinaldo Conrad, the Russians, and Ben VerHagen sailed Doesburgs;
Craig Whit-worth and I had wooden half double bottoms from Ian Peden in
Sydney. The top New Zealand boat, Ron Watson, had a shell that was
seven years old -- though the deck and double bottom were more recent. There
were no Alpa boats to be seen anywhere in Europe. There is a relatively
new Italian fiberglass FD made by CIMA in Rome that features a very workable
half double bottom setup, and there were two of these in the Worlds.
None of the boats had any major trouble measuring in. (All the Worlds
were measured in completely.) Pattisson' s Super...docious was measured informally
with the new full-width templates, and it was perfectly legal. There is
much talk about "hull shape" in FDs. The Hoare, Hein, and Australian boats
are certainly closer to the tolerance limits in many places than the Doesburg
or Plastrend hulls, but it must be remembered that the difference is only
a few millimeters.
Sails: Pattisson used the same sails he had at Acapulco (Musto
and Banks mains, Tasker and Seahorse jibs, and
Musto or Banks chutes). Oaeger used mostly French Taskers (from the French
loft run by Bertrand Cheret). Musto used Musto; Conrad used 4. suits of
Mustos in every combination possible -- he himself admitted to having too
many sails; Whitworth used Whitworth; Watson used Pederson sails. The newer
Musto spinnakers are perhaps not as flat as before. He uses American sailcloth
now and they look much better. Whitworth made some fuller-than-normal sails
for himself and for me; his standard Australian Cut was much too flat. Pederson
sails are rather popular in Europe. I also saw some local European sailmakers
represented, so people don't really feel that one has to buy from the "English
Establishment" to go fast.
My own thoughts about the sails that Pattisson used, with which he was
as fast (rarely) or faster (usually) than everyone else are these: his
jib was full and his main medium-to-flat, draft set on a stiff spar. He
would change his sails for heavier wind, but the jib would still be full.
It would have the draft oriented differently, however. His heavy air mainsail
was primarily just heavier cloth, and perhaps just a bit flatter. His spinnakers
were no extreme shape, just standard 3/4 ounce Banks or Musto.
Spars: Procter has a third method now for tapering the head of
the B section. All three types of tapers were at Naples, but I couldn't
see any clear difference in the bending charact-eristics. Pattisson, of
course, had his Alspar section from Australia. Rather than call it an Alspar,
it should be called a custom made spar, for the Alspar people themselves
couldn't make another like it. It measured in about 2 lbs. heavy, and though
the top was very finely tapered, the total spar bend was a very smooth
curve. He sailed with the spar slightly stiffer all around than a standard
B section. Nearly all the boats, with or without diamonds, had a lever or
cam fitting so that the mast brace at deck level could be controlled by
the helmsman. The single spreader rigs usually had their spreaders slightly
too long (2 inches) and permanently fixed a little forward.
One of the more interesting aspects of the regatta was the evenness of
completely different rigs. Three boats in the top six (Musto, Whitworth
and Watson) had fully standard deHavilland spars, with diamonds and halyards
external. Tom Allen and I were the only ones without diamonds on our deHavilland
spars. (The Australians said that it could not be done.) The boats with
diamonds had them adjustable by the helmsman, and the spreaders were completely
in line with the shrouds. The diamonds were straight athwartships, not angled
forward.
All the boats except the Australians would fix the jib clew, and then adjust
the jib halyard and shrouds to achieve the proper trim. (Loosening the halyard
and tightening the shrouds will free the leach.) Most rigs showed some con-cern
about windage; many shrouds were fixed internally, and there were some very
pretty aerodynamic spreader shapes.
Incidentally, it is no longer legal to shackle the mainsail up; the crew
in the boat must be able to lower it while at sea. Also, Pattisson was
not using the electric relative winddirection indicator that he had at
Acapulco, which has also been outlawed. Most boats used as stiff a boom
as possible; the foot of a modern FD main is too full to be flattened by
boom bend.
Boards and Rudders: Pattisson and a few of the others showed a great
interest in centerboards and rudders. He measured in 3 boards and 4 rudders,
each with a slightly different shape. The centerboard he used the entire
regatta weighed 9 pounds. His tiller was permanently fixed to his rudder,
and the entire assembly was amazingly light. His rudders varied as to thickness
and the angle at which the blade was raked back.
Tom Allen was the only boat that sailed with less than the maximum rudder
area in the water. No one sailed with the rudder angled back from the vertical
more than 30 degrees; most had them straight down most of the time.
Many different materials were used for the centerboard stripping; stiff
mylar, Dacron, pure and reinforced rubber, and plastic. Pattisson reportedly
had some sort of foam inside the box. Whitworth had a "plug" that he would
fill the slot with behind the centerboard when going upwind -- but he had
to pull it out to raise the board.
Equipment Layout: Most boats were built around their system for
changing the jib lead. Pattisson had a separate "string" for each shroud
and the jib halyard. The other extreme was John Sully of South Africa, who
raked his whole rig forward or back with one crank at the skipper's end
of the boat. Nearly all the fittings were custom made. That was true also
of the deck-level mast cams.
Main travellers were varied, but all were very workable. The "best" systems
were those which allowed the slide to be easily brought up to weather.
All the German-made boats had the traveller in a concave arc -- the middle
was lower than the sides in order to encourage the slide to move out more
easily. Pattisson and most of the fleet had centre main cams.
Spinnaker sheets were all under the deck. Pattisson had an intricate
but workable system for raising and lowering the pole from where he sat.Whitworth
had the distinction of the only boat without a spinnaker launching tube.
Many of the boats had a very useful hook on the underside of the boom about
two feet in from the end, to hold the chute sheet up and out on quartering
reaches. Whitworth had the only boat with the jib sheets above the deck.
Most of the Hoare boats had cams on the leeward side, but also popular were
clams on the windward side. A few boats had sheaves that could be moved up
and down, but not under load. And on many boats the lead position could
be moved inboard, but as far as I saw no one did this, even on the days
with relatively flat water.
Compasses are standard equipment on FDs in Europe. The flat-case, lightweight
plastic ones made by Suunto in Finland are very popular. Pattisson uses
a pair of these, one mounted by each shroud.
Tactics: We thought that starting was the easiest part of the race
in Europe, in many respects. Most importantly, all the boats seemed to
realize that clear air was essential, so the fleet spread open quickly.
Even if we had a 2nd or 3rd row start we would be at least a little clear
very soon.
Pattisson, Whitworth, and several other good boats favored dipping down
from above the line, especially on the first start. (There was usually at
least one general recall.) With the leeward end favored it was likely that
the "good" boats would be at least a third of the way back up the line from
the pin,Windward end starts were the most difficult, but still more likely
than not the fleet leaders wouldn't be fighting for the best start.
It is very difficult to identify what technique permits some of the boats
to tack so fast. It involves not only the crew going from wire to wire
and trimming the jib quickly; also important is the wave pattern that the
boat turns in, the way it is rocked and turned by the helmsman, the course
that the boat ends up on, and the way the main is trimmed throughout.
I've already remarked about main travellers being up to weather often.
Pattisson worked his constantly, working through the waves with it as much
as with his rudder. Depending on relative fullness of the main, different
boats would be carrying their travellers in different positions. In order
to maintain a "twist" in a full mainsail (or on a stiffer spar) the slide
was almost always to weather, with the sheet relatively eased. The things
to be watched were the set of the leach and the position of the boom relative
to the center of the boat, The reaching legs most of all showed the practice
and "time-in-the-boat" edge that Pattisson had. Particularly in the semi
-planing conditions, he would hit the proper trim for his boat very quickly
and be off. It was simply practice.
We never had the difficult, lighter conditions, so I can't comment on Pattisson's
downwind tacking abilities, Most of the boats kept their crew centered
fore and aft, but as far on opposite sides as possible. Crew weight would
be shifted quickly, mainsails pumped once, rudders flipped once or twice,
all to initiate planing or a long surge. They were very effective techniques,
taking a good deal of concentration.
The well-practiced boat could gain significantly rounding the ma rks,
too. The last part of the reaches were sailed to provide a clear air position
as soon as the mark was rounded; important both at the 2nd and 3rd marks.
It was much easier to concentrate on boatspeed on the 2nd and 3rd windward
legs, chiefly becuase of the much simplified tactical situation.
The long runs featured some speed differentials that were hard to analyze.
At Naples it was usually 15 knots of wind with only small chop, so so downwind
tacking to speak of, but still some boats could easily sail by others.
Possible major causes would be the smoothness of the bottom (not the type
of paint), the rudder shape, steering technique, the centerboard stripping,
and weight distribution within the boat. The sails seemed to be too similar
to matter.
Typical races sailed in a relatively steady wind would show few positions
changed after the first beat, until the last half of the beat to the finish.
My explanation would be that in the final minutes of the race the tactical
situation becomes much more important -- and accordingly, some people lose
that little extra concentration on boat speed that others (Musto for one)
could maintain. That is the biggest lesson to be learned. The boat must
be kept moving fast through the water at all times.
