Rigging dimensions for sculling boats
Ward C Campbell, Jr.
A request for recommendations concerning best reading, reference information
on the rigging a single/double scull. I want to make sure that the rig for
the single of a sculler I'm working with is as efficient and correct as
experience will allow. Lots of sources on rowing, I've found few on
sculling boats of modern vintage, eg. wing rigger types. The question came
up when another individual looked at his sculling and came to the conclusion
that he was hopelessly rigged, a function of the manufacturer and their
particular system. My questions concern the less obvious, like
distance/depth between footstretchers and seat, footstretcher angle, how far
to the work, outboard pitch of the pin, etc. Any recommendations for
sources I can access to make sure all issues are addressed would be greatly
appreciated!

You'll find as many different ways to set up a scull as there are scull
manufacturers.
It goes something like this:
Set you span to 160cm or whatever is best for you.
Set you pitch to 4 degrees, or whatever is best for you.
Set rake angle to 45 degrees, or whatever is best for you.
Set your inboard to 89cm, or whatever is best for you.
Always add a little lateral pitch but not too many riggers are going to
let you do that. (Eh, Carl :^) )
Only one I'll suggest for sure is set your shoe height by aligning the
ball of the foot with the bottom of the seat when at front stops - but
I'm sure someone will say "whatevers best for you".
Oh, and shins never to go past the vertical which is somewhat dictated
by the placement of the shoes.
There are probably good books around but I've never used one.

Not worth trying to pull the same gearing as Matthew Pinsent if you are half
his strength and fitness, even if you are the same height. I think that is
where the "whatever is best for you" comes from. You may be able to get
some useful measurements when using an ergometer (e.g. a RowPerfect fitted
with a computer will measure your stroke length for you). This will tell
you some of the measurements you need, and it is easier to have someone
measure your seat position relative to the stretcher etc when they can stand
right next to you. That will give you, or a friendly coach, something to
work from.

Individuals can have their rigging personalized from these measurements.
One thing that is often left to chance is the height between the heels and
the oarlocks. I have seen the range of 15 cm to 20 cm for most people.
Once again, the size of the individual is important. I was coaching a
lightweight double, but I couldn't seem to get the body angles at the catch
to match. I knew that one guy I longer legs, but the heels were already
different by 2cm. Finally, I measured the distance from their heels to
their knees. I found that they were different by 7. We wound up with the
bow having his shoes set at 16 cm and the stroke was set at 22 cm and that
finally seemed to work.
A great source for all rigging is a book by Michael Purcer. I have a copy
of his first book, printed in 1985. I know that he has updated his book.
If his book is available, the best chance of finding it is from Regatta
Sport, and they are on the web.
Good luck

This site lifted all the numbers from the appendix of Redgrave's book,
and provides ranges as well as "normal" values:

My legs are relatively long, so I try to set my shoe height lower than
that. Otherwise I end up with my knees beside my ears at the catch. (-:

So true, Tony! But there is one product that does - the AxioR pitchable
(& absolutely non-slippable) rowing & sculling pins - the only "dial-a-
pitch" system.
Goes best on an AeRoWing rigger, of which you'll see a fair few in
Sydney.
But now a horror story, told to me at the GB Nat Champs a week back:
A Midlands University loaned an eight to a nearby club. This boat had
our AeRoWing riggers. The University club reached the Nottingham course
a few days later, just in time to see their generously loaned-out shell
being "re-pitched" by means of a scaffold pole applied by a moron to its
AxioR pins!!
This reflects so badly on the intellect & decency of the club in
question that all names are withheld, as is what happened to the
miscreant's crown jewels.
