Difference between (Empacher) LW and LM 1x?
Ewoud Dronkert
course. Maybe you could help me out here. What exactly is the difference
between 65 kg (LW) and 75 kg (LM) Empacher single sculls? I know they're
both K13 shells that means they're from the same mould.
Are they cut off at different heights? Is the interior built in lower or
higher? Surely the rigging ranges are different?
And what about Filippi or Douglas; do they use the same principles? (I
believe Douglases are all different shells for different weights?). TIA

Correct, Ewoud.
While other manufacturers tend to limit themselves to 2 hull moulds &
cut these down for smaller clients, we understand that competitive
scullers come in many sizes &, accordingly, we offer 6 scaled sizes
between 60kg (W LWt) up to 100+kg.
To cut down the sides of a larger hull for a smaller rower means putting
that person into a boat which you know is really better for someone
bigger. With the reduced depth of immersion under the lighter person
that boat's immersed cross-sections become more like the saucer & less
like the cup. If the cup-shaped immersed cross-sections were "right"
for the bigger person, the saucer-shaped immersed sections with the
smaller person cannot also be "right".
Furthermore, the wetted surface of a given boat size is rather
insensitive to modest changes in displacement. Thus putting a small
person into an oversized boat means that, at any given speed, they must
overcome almost the same amount of fluid friction as the bigger person.
So it is our view that the act of cutting-down the sides of a boat to
carry the smaller rower is, at best, merely a gesture towards the
smaller person's sensibilities & reduced freeboard requirements.

Maybe you will, me coaching at a worldchampionship or something :) I think
I'll be calling my *local* shipyard representatives..

Will the other boatbuilders' representatives be any more ready in
private to give you rational technical answers to your very relevant &
interesting question than they are to provide them in public, here on
rsr?
Does not such reluctance to discuss a technical matter so relevant to
their products' performance under rowers of "other" weights seem
uncharacteristically coy?
Ewoud Dronkert
> private to give you rational technical answers
I don't know.. We'll see. Different shells for different weights may even be
a disadvantage as the boat(s) will be used for 10 to 15 years on the club,
and thus not always for the same person (or category). Now if we were a rich
club...

impaired by its hull lines being correctly proportioned (rather than cut
down from something larger), but its performance with users weighing
within its optimum range exceed that of the cut-down job.
A club, in choosing hull sizes, has to reach 2 decisions:
1. Are its lighter women, say, members of equal importance & rights to
other club members?
2. Will they really average 70kg, or will their average be around, or
below, 60kg?
If the answer to the first question is "yes" (can it be otherwise?) and
to the second question is "60kg", then I submit that the choice should
be loaded towards the boat actually designed for 60kg, not a cut-down
70kg.
Only then, IMHO, do you factor in prices/availability/quality/durability
/service & support/etc., along with the club's funds and ambitions.

factory and cannot answer from first-hand observation. But I am told that they
are two different moulds, different seats, and rigged to the customer's
specifications.
I could not tell from the inquirer's email address where this guy was
from....if it was a guy for that matter. :o) There was no indication where
the message was coming from. (should always let the readers know where you're
from, IMHO). So why not ask him to call me here in Boston, Mass. USA?
I'm not the boat builder, just their best darn salesman. :o) (modest,
too!). And I try to "know-all" and seldom get stumped, thank you. When I
can't answer a question, I call "the boss man" at the mother ship. No big
deal. It's the folks who pretend to know all that are dangerous. And
Carl......you're NOT one of them! Cuz you DO know all! :o)
One thing's for sure, you're not likely to find a one-size-fits-ALL boat
anywhere. Good luck, and hope you chose something yellow. :o)

There are three different moulds for Empacher's racing singles, the K13
(60-75kg, 7.78mx0.28m), the K18/R18 (70-85kg, 8.00mx0.285m) and the K12/R12
(85-100kg, 8.33mx0.29m). The R is a wingrigger, the K has normal riggers.

not so well informed apparently!
I did visit them, however the above info came directly from their technical
literature.
More:
2 scull and sweep: 5 moulds
4 scull and sweep: 3 moulds
8: 3 moulds
And Bill, this was 4 years ago.
