Seat discomfort is a significant problem in rowing &, as you indicate,
Henry, has the potential to drive people out of the sport.
The rump was not designed for sitting upon, even less for sitting on and
then rocking back and forth. Putting it frankly, no 2 arses are alike,
any more than any 2 faces are identical - a plaster cast of your face
would never fit mine, nor anyone else's. The bit that we rowers choose
to make load-bearing is anatomically variable & complex. Under the skin
in the area carrying our weight run muscles, blood vessels, bones and
nerves. The problems which can arise range from excruciating
bone/seat-hole-edge contacts causing bruising & abrasion to problems of
lost circulation in the leg, sciatica, damage to the bursae (internal
protecting pads meant to protect vulnerable structures) & lower back
muscular spasms. Some of what seem like passing problems can even
become lasting disabilities.
Rowing has steadfastly ignored this problem, so people who might have
benefited greatly from rowing, and benefited rowing greatly too, drop
out, some with lasting injuries. As just one simple point: the most
prominent tips of the ischial protuberances (sit-bones) can be as little
as 100mm apart on some men and 165mm apart on some women. And the
shapes and alignments of those structures vary so widely between
individuals that they could probably be used as identification aids,
just like finger prints or iris scans (but rather you than me!).
Our pelvises are often markedly asymmetric - ever wondered why that 1x
seems always to run down on 1 side, or that finish is always harder to
extract? And then there's the problem that some of us are more simian
than others, having a coccyx which gets over-close to the back of the seat.
In short, while a good 90% of rowers will "get by" on average rowing
seats, the reality is that as many as 10% have a miserable time. And
that's not good.
Some 30 years ago a group of boat-builders agreed with the FISA
Materials Commission that to assist equipment interchangeability there
should be only a limited number of seat track separations: 165mm, 230mm
& 280mm. That was yet another agreement on rational standardisation
which was too often ignored & which might have made having your own seat
(as part of your own rowing kit) a more feasible solution.
When we build a boat (& we are largely building for known individuals)
we request their anatomical data - a so-called bum-print - you can find
out all about it on the fittings & resources pages of:
www.carldouglasrowing.com
As Henry kindly says, we create for each person a "custom seat" which
won't press against their sensitive bits, which really will support them
on the bits than can take the load & on which they really will be
comfortable. And there's a hidden advantage - that the seat fits _you_
so well it is less likely to fit anyone else, so only a fool would steal
your seat.
Cheers -
Carl
