Issue with vehicle speeds?

Posted on reddit just now but posting here as well.

Issue with vehicle speeds? I am racking my brain and getting tired. :)

Here is the situation/issue:

In discussing a custom ship speed (gephard class fast attack) with players, it seems there is a discrepancy with vehicle speeds being slow.

The gephard is 40knots max per wikipedia.

Per rules, the pegasus hydrofoil is 6 combat and 7 travel when in hydrofoil mode "foilborne". per wikipedia the pegasus does 48knots or 88.9kph (55mph)

6 hexes per fast action (9 if 4 successes rolled), giving 12hex (120m) normal and 18hex (180m) max.

Speed calculation https://www.calculatorsoup.com/calculat ... ulator.php
shows
120m in 10s as 26.8 mph
180m in 10s as 40.3 mph max

if you gave it a 7 combat spd:
140m, 31.3 mph
200m, 44.7 mph max

if you gave it 8 combat spd:
160m, 35.8 mph
220m, 49.2 mph max


Comparison with other combat speeds per rules:
People 2 hexes per fast action 20m, max 50m (+3 successes). Total max 100m. 100m world record is 9.58 seconds for men 10.59 for women. 10 second round this is reasonable.

However there is discrepancy again at vehicle level.
2WD car is combat spd 6 on road (same as the pegasus hydrofoil above, max 180m / 40.3mph) and yet the car's travel speed is 10 while the pegasus hydrofoil is 7.

M998 HMMWV is combat spd 5 on road (100m / 22.4mph, max 160m / 35.8 mph). Top speed per online with max weight is 55mph.


55mph in 10s is 245.9m (putting it at max combat spd 12, reduce this by 3 for potential successes gives you combat spd 9 not 5 or 6).

Now one can argue that road conditions are horrible in the world of twilight 2000 which would reduce max speed so I will not argue that the ground vehicle speeds need to be adjusted.

Open sea and river terrain in hostile waters are both x1 spd. Arguably river bends/avoiding obstacles slows down max spd like ground vehicles, but open sea?

If open sea had a x2 for spd the pegasus would have a combat spd 12 on open sea (120m/150m per fast action, 240m/300m total, or 53.7mph/67.1 mph) so that I think would resolve that issue for the pegasus in combat spd.

Travel spd though?

55mph for 4 hours is 354.056 km (531.084 km for 6 hours). 10km hexes, that is between 35 and 53 hexes. Keep in mind the 2WD car is travel 10 and the pegasus is travel 7.

I ran out of time to go further right now, but what do you folks think?

Have you run your numbers at 5 sec/round? A round is an indeterminate period of time between 5 and 10 seconds, so there is a lot of fudge room in speed values.

(On the subject of the M998, we will, of course, ignore that the M998 is a very specific configuration of HMMWV, one that does not have a weapon mount, and assume it is meant for most variants. Even if we should really increase rear armor to 2 for the various armament carriers.)
