For a manual power, perhaps 4 people:
each cabin hold 2 people, the cargo area is just walled, and holds up
to 200,000 lbs. the GVB statistics give approximate dimensions...
TL03 Barge Poled
Subassemblies: Vehicle +7, Body +7.
P&P: four rowing oars (average ST 12).
How does performance change if this is a poled vehicle instead of
rowed?
GVB does not have a "poled" option. :)
With an ox pulling it (note that this speed is realtive to the ox,
not the water):
TL03 Barge Towed
Subassemblies: Vehicle +7, Body +7.
P&P: staff and collar harness (2 hexes of ground creatures, total ST
30).
I'm assuming these numbers are 3e, because we don't exactly have our
Ve system for 4e. That said, 3e cattle have ST in the 40-80 range
acording
to Bestiary, and Oxen should be at the high end of that, being the 1.5
to 2 ton type, rather than the half ton type which I assume are dairy
cattle, and cows to boot. If you have a ST 70 ox pulling, rather than
a 30, what's the performance like? One ox being 2 hexes of ground
creature :D
Oops, I've been working on too many 4e creatures... but the slowest part is
the streamlining of the craft, from my juggling of the numbers. I had had at
one point ST120 of creatures and the speed didn't change.
I think it's because GVB is putting the oxen in the water, thinking that
they are swimming and pulling it.
Also, if you substitude Hobgoblins for oxen (say, ST 14 for
"professional" towmen) do they need different harnesses ergo different
efficiency? Or can I sub in two 4e ST 14 hobs for your 1 3e ST 30 ox
and
get approximately the same results?
Yes, by good fortune. The cost for the harness is measured by the hex, so it
costs the same for a ST28 2-hex creature as two ST14 1-hex ones.

here are a couple of sites that have something barge realted:
the Fenlands, would have measured about nine metres in length, with
a cargo-capacity of around eight tonnes".
Pullum. The ships were flat-bottomed and 20-35 m
Nordrhein-Westfalen. 14 m long flat-bottomed
cargo ship, Lake Constance. This 18 m long hull
Hmm, GVB suggets 71' -> 21m. Very plausable from the ranges below.
Although the cargo capacity is 100 tons, with another 100 tons before
flotation is compromised.

In the UK, we used horse-towed barges on the canal system (i.e. static
water), but not on rivers; the water speed is usually too high for an
animal tow to be effective. On a wide river you can use sails to get
upstream; on a narrow one you're stuck with oars.
I beleive that we must assume in this fantasy world that no one dredges or
clears the rivers (other than around towns)...

Note too, that the Oxen do not get to apply their full strength to
pulling
a vessel or a plow or a wagon. GURPS LOW TECH gives rules for this
that if you want, I can dig up sometime tomorrow morning (I have to
go to bed now and then go to work).
GVB includes an efficiency of 1.5% for the shaft-and-collar harness, a
cutting-edge TL3 invention. (previous efficiencies were 1% and 0.75%)... TL5
will bring the whiffletree harness with 2% efficiency. (p. VE29)
(hmm, BE40 gives an average draft horse ST60 (3e)... Converting at 0.02 to
kW = 1.2kW =1.6 horsepower. Go figure.)
