Wha about Hudson? Their boats did well at the last Olympics and the new 8
has many design improvements over the above mentioned boats. Such as 4
wing riggers for the 8+.

Just could not help but point out
2 x Vespoli or Hudson 8+ = 1 x Empacher or Resolute

In article <Pine.GSO.3.95.970204230955.21554B-100000@pirates>, oarsman says...
I'm pretty sure the Hudsons and Vespolis raced at the Olympics were
custom, made-to-order boats. I believe these are not (at this point
in time) the boats available "off the rack". If you order a regular
shell, I don't think you're going to get an 'Olympic Special'. However,
I would presume that anyone COULD order a custom boat from them,
provided they fork over the money.
Unfortunately, the reality is that you have to pay for speed, and a
$4500 boat (1X) is not in the same mould as a $7000 boat.
It has been argued that the disparity of quality--cost may be lessened
however, if minimum weights are increased a bit. I believe this is one
proposal before FISA's impending congress, isn't it?
As far as good service goes, I would have to single out Alex Selvig for
his excellent handling of Filippi (curiously not included the original
discussion thread). Communicating with Empacher by fax is pretty decent
as well.

I cannot speak for the Vespoli 4- raced by the US Lwt. Men, but the
five Hudsons used by the Canadians (Women 1x, Women 2-, Women 2x,
Women 4x, and Lwt. Men 4-) were all "off the rack". The only
modifications (beyond Silken's 1x) were made by the coaches (i.e.
rigging). All lessons learned by Hudson from the use of their boats
at the Olympics Championships are used in all future production boats,
regardless of who they are for. The cost of these "Olympic Specials"
are those published by Hudson.
Silken' 1x, on the other hand was a custom built boat, albeit with the
same hull shape and construction as you or I would receive. Her
cockpit was lower than the production models (by her own request) and
she had a rigger made of larger diameter aluminum. Hudson will make a
custom rigger for anyone if asked.

As described, a Hudson hull (mould) is a Hudson hull. You can be
assured that if you pay $4500 (give or take) to Hudson, you will
receive the same hull as Silken, if you order the same size.

I can't argue with the quality of service Dave Trond provides and
can't comment on Alex Selvig due to lack of experience, but I have had
very good experiences dealing with Gord Henry (crew boat sales and
service), Hugh Hudson (singles sales and service) and Jack Coughlan
(owner) at Hudson.

It costs more money/time to make a boat stiffer and lighter. End of story,
unless you don't mind rowing a 30 pound rubber noodle at the Worlds.
The boat is not THE determining factor of speed, but it is A factor.
And yes, times have gone down significantly since the introduction of
carbon fiber boats, lighter stiffer oars, better riggers. Mind you the
hull shape has not changed too much, exception: Resolute's efforts with
their eight.
Bottom line: if you think you can lug it down the course row it, but
don't be alarmed if an equally talented rower passes you like a
black-striped yellow blur ;-)
Not saying others can't make a good boat too....just saying you'll
pay for it, German, Swiss, Aussie, American, Canadian or Swahili.

Greg, you're right all the way around--and what color single do I row???
I think that FISA is gonna shoot down the increased boat weight
proposal; we'll know for sure by next week.

Actually talking to Emparcher, their arguement to FISA is that raising
the weight will have little impact on the price, no impact on quality
but a significant impact on the 'race life' of the boat.

I would argue that if a boat can last you five years instead of three,
then the ultimate result IS cost reduction. You'll still pay the same
price for most boats...you just won't pay it as often...

BTW - what was the outcome of FISA's decision on whether to raise the
minimum weight?
Greg Doyle
Philadelphia, Pa.
Charlie uses Kevlar 149 fabric in his Dirigo line of boats. Kevlar is
pretty interesting stuff with some major plusses and minuses. It,
because of its relatively low density and reasonable strength/stiffness
properties, has better SPECIFIC modulus and strength properties than
standard low-cost graphite. It also tends to stand up to impact damage
better than other composites. It has some drawbacks also. Kevlar has a
greater ability to absorb water than do other common 'composite' fibers.
It does not tend to bond well to the epoxy that is used with it to
create a composite. Both of these drawbacks tend to degrade the
structural performance of the boat (lets say overall structural
stiffness) at a faster rate than a composite boat made from glass or
graphite fibers. Kevlar is also susceptable to UV degradation. Seeing
that it is encased in a resin that has anti-UV additives, this is
usually not a problem. If you give a darn, have a look over at Dupont's
website
(http://www6.proxima.com:80/owens/composites/about/comparison/fiberdata.html).
The page is a fairly accurate table with some of the properties for
glass, carbon, and aramid (Kevlar is Dupont's brand) fibers.
When one is looking for a boat and you're told it's made of carbon fiber
your next questions should be:
- What kind of carbon fiber? (lots of different kinds with lots of
different material properties, some stiffer and stronger than others)
- Is it uni-directional or a woven textile form? (uni-directional
composites retain more of their IDEAL fiber properties)
- What percentage of the fibers used in the boat are carbon and what %
are of other types? What are those 'other' types and their properties?
- What is the fiber-VOLUME of the composite in the boat? (How much of
the composite is fiber and how much is resin - very important! A well
made aerospace grade composite structure made from pre-preg will have
around 60% fiber volume. Decreasing percentages of fiber in the
composite have a MAJOR impact on material properties like stiffness and
strength. I would guess that the standard hand layed-up boat would have
fiber volumes significantly less than 60%. More like 40%.
Lots of things to worry about but hey, it's your money!
Please note that I still firmly believe that a good crew in a bad boat
will SMOKE a bad crew in a good boat any day and all day.
Cheers,
c.

Exactly the point I was trying to make [from the conversation with
Empacher]. Assuming life is defined as length of 'racing stiffness
usability'...the life is extended according to some boatbuilders 2x by
using more expensive materials...and since the cost of a boat is
largely labor the net dollars/pounds/marks/etc over say a 10 year
period is significantly more with inferior materials.

Actually this did not come in the mail that I have received so I
don't know but will post when I find out he outcome [or someone else
can if they find it out sooner].
