Relativity in Derby

   Posted by: Bitches Bruze    in Rules, Strategery

There are many aspects of derby where what you have passed or what direction you are going happens and it can be tricky to remember is it in relation to skates or my hips?

I have a really simple rule to remember this: If you’re comparing a skater to another skater, you measure by the hips. If you are comparing a skater to the track, you measure by the skates. Let’s take a look at the rules which fall under each. Note: The following rules are paraphrased.

Measure by the Hips Jammers become lead jammer after passing the foremost in-play Blocker’s hips
3.4.3 A pass is determined by the skater’s hips (for lead jammer eligibility) Pack skater proximity is measured from the hips
4.2.3 Non-pivot blockers line up behind pivots (who are on the pivot line) as demarked by the hips (of the blockers and pivots)
6.11 All cut track penalties are in relation to the hips of on-track skaters at the time a skater was knocked out of bounds except for the skater that initiated the hit. If the skater who initiates a hit succeeds in knocking an opponent out of bounds, she is considered in front of that skater for the out of bounds skater’s legal return to the track regardless of who was in front when the hit happened.
8.3.1/8.3.2 All scoring is in relation to passing opponents’ hips (in the current rule set, jammers need only be IN BOUNDS to score, they don’t even have to be on their skates or skating)


Measure by the Skates

2.4.4 Skaters have to be on the track when the jam start whistle blows Helmet covers may only be recovered with clockwise skating
4.2.2 Only pivots may line up on the Pivot line
4.2.4 Jammers line up on or behind the Jammer line
4.4.2 When the reamost pack skater has crossed the pivot line the jammers are released and the jammers may not be accelerating when their whistle releases them, but they may be moving, coasting or braking. Only players who are stepping and/or skating in the counter-clockwise direction may execute a block (this one trips people up some times because direction of game play is related to the TRACK not the target – see next cited rule) Skaters must not skate clockwise in relation to the track when executing a block
6.8.1 Skaters must be in bounds when initiating a block
6.8.5 A skater may not initiate contact with an opponent who is completely outside the track boundary
6.8.6 An inbounds skater may engage with an opponent who has any part of her skate in bounds.
6.8.9 Skaters who cease contact with the ground maintain their in bounds or out of bounds status until their skates touch down again
6.8.12 Skaters can hang skates and body parts over lines and that doesn’t matter – only touching matters
6.9.2 Skates may not be moving past the perpendicular line in a clockwise direction when assisting
6.9.3 Skaters may skate clockwise so long as they do not engage other skaters
6.9.4 Clockwise movement (in determining direction of game play penalties) is measured by the skates moving past a line perpendicular to the track boundaries (ie – clockwise – perpendicular is still counter-cl0ckwise)
6.9.6 Skaters may face any direction while blocking and assisting so long as their skates are moving counter-clockwise
6.12 Skating out of bounds penalties are about picking up speed with your skates while out of bounds
7.3.2 When a skater is sent to the penalty box she must exit the track and skate to the box in the counter-clockwise direction


6.8.7 If any part of a skater is touching out of bounds (this includes non-skate parts) she is considered out of bounds and may not engage other skaters
General Practices: Usually a “point of no return” is provided to define the penalty box. If any part of a skater is still touching before (clockwise) of the point of no return line, she is considered to not have passed the box and may take a seat without another lap.
