Ask
people to identify the objective of racing and most will agree that
it is the search for greater performance that drives designers,
builders and competitors but in recent years and with safety as
a priority, the definition of performance has changed. It is no
longer enough to get the best from an engine for now, alongside
performance on the water, the target is the parallel pursuit of
higher performance from the structure of the boats themselves when
something goes wrong and this is a consideration in offshore, circuit
and formula racing alike. The human body is fragile, particularly
when subjected to physical battering in an accident or collision
and the structure of the cockpit/canopy is the only protection from
impact damage so construction and attachment is critical.
The
problem was highlighted in early 1998, when following a fatality
in a canopied Class II offshore monohull, the UAE Marine Sports
Federation decided to cancel all Class II and Class III 6-Litre
racing in the Middle Last until the question of cockpit protection
had been investigated and designs improved. With the advent of canopies
ten years ago in offshore, the problem appeared to be more psychological
than practical, as drivers apparently believed that they were invincible
once behind and below a perspex screen but almost all boats shared
the common failing that their cockpits were often not properly engineered
as part of the boat’s structure and this shortcoming has been addressed.
Despite
previous testing and development, formula boats suffered from the
same problems so all branches of the sport have concentrated on
looking behind the cosmetics of canopies and safety cells. Tasked
in 1998 by the UIM and Cees van der Velden, Benetton Formula’s Steve
Davies instituted a detailed and onerous programme evaluating existing
El cockpits with the objective of producing a single test standard
by which all future manufacturers would be measured High speed side
impact was considered to be the worst case encountered on the water
and the material evaluation used was a 3-point bend test on 300mm
x 50mm sample panels submitted by three top builders. Davies’ conclusion
was that the tests he had performed highlighted the need for a more
extensive and specific programme but that optimistically, boat cockpits
could be massively improved with more diligent research by the builders.
One major recent
advance in boat safety has been initiated by Guido Capellini. Conscious
of the difficulty experienced by the Osprey Rescue teams in recovering
drivers from their boats after a barrel roll or flip, when either
the boat is impossible to right or it floats with its cockpit and
thus driver submerged, Cappellini has developed a two stage automated
stability system.
Firstly, it allows
water ballast to be taken on rapidly to pull the transom downwards
and in parallel, fires off a 200 litre capacity airbag located behind
the driver’s head restraint. Jointly, the weight of water brings
the boat into a vertical position while the air bag raises the cockpit
clear of the water to facilitate easy access and rescue and it is
viewed as a most significant advance by independent observers and
drivers alike.
Other significant
safety measures adopted in 1998 included a re-wording of the rules
covering pickleforks. The most forward end of the sponson must now
be deformable starting at a maximum of 140kg. and be designed to
crush with the main body of the sponson ending in a minimum lOOsq.cm.
forward bulkhead of a minimum 5mm marine plywood or equivalent material.
This bulkhead must be an integral part of the structure and must
have a rounded area of at least 10cm. length. Additionally, the
picklefork must be demountable and have nothing inside, have a front
end of a minimum horizontal radius of 35mm. with a minimum radius
of 20mm. in all other directions and have a GRP lay-up of three,
two and one layer at its tip.
Further rules immediately
instituted include mandatory cockpits for both 0.500 and 0.700 classes,
where the driver races in the sitting position and a series of new
minimum hull weights and weights including boat and driver of l2Okg./l9Okg.(0.250),
30kg./210kg.(O.350), 18Okg./26Okg.(O.500 & 0.700), 100kg/17Okg.(OSY.400)
and 200kg./250kg.(HR. 1000). All branches of the sport remain under
the most vigilant scrutiny by the UIM’s Commissions and safety continues
to be at the forefront of all future developments.
