Measurements of L and S compared to full card measurements

This year I’ve noticed many players measuring L and S incorrectly, usually by using a full card length of a ship deckplate on the top side or using a crew card to measure.  Various third party accessories have also become quite popular, as sometimes a deckplate card leaves some maneuverability or angles to be desired, such as when trying to determine a close measurement or for premeasuring move actions.  I got my vernier calipers out to see what distance differences there are between S, L, full card lengths often used in their place, and some extra straws and tubes I’ve been using.  Disclaimer: Measuring with or without the black border lines on the S and L segments may produce slightly different measurement results.

I used the back of a spare Martinette deckplate that I’ve been using for years as my primary measurement tool, as well as an HMS Goliath deckplate to confirm accuracy given that my official card has been exposed to so much playing that perhaps it isn’t 100% accurate anymore (this experiment determined that to not be the case, though I should swap it out if more finish comes off to the point where I cannot determine the endpoints of S or L).

I measured L at 83.8 millimeters.

Using the other side of the calipers with the Goliath card, I measured the same 83.8mm.  It may look like the number should be higher, but that’s because the calipers are slightly above the card and I couldn’t get a camera angle showing it head on at both ends.

Next was the test using the entire length of the card.  This came in at 89.2mm, a 5.4mm bonus compared to L actual!

In a separate test on the wrong side of the Goliath card, this number was confirmed:

S was next.  The official distance comes in at 57.5mm.

The Goliath S segment measured exactly the same.

Now came another full card test.  Standing the Martinette deckplate on end and pinching the calipers to it, we see a measurement of 63.7mm!

Perhaps this measurement was slightly off, but the “inside calipers” still showed the Goliath card at a similar number.  If you average these two measurements to approximately 63.5mm, that means that measuring with the full width of a Pirates card gives you a 6 millimeter advantage compared to using the proper S distance!  As anyone who has played the game surely knows, that can easily be more (sometimes much more) than the difference between: docking vs. not docking; being in or out of range for cannon shots; being in or out of cancelling range, etc.  Even if you don’t add up how big these differences would compound over the course of a full game, any one instance of these measurement differences could be the difference between winning and losing.

Now it was time to test some unofficial segments.  Fittingly enough, I did not make any of these myself, though I have used them in games somewhat consistently, though I still try to use my deckplate most of the time.  That I didn’t make them is not to clear my name of any wrongdoing, as I have played many things wrong in the past and will likely accidentally screw up additional rules (hopefully just minutiae) in the future.

An S straw I received years ago in an eBay lot measures 58.1mm, very close but still .6mm more than 57.5mm.

An L straw from the same lot actually came in slightly short at 83.6, .2mm less than the 83.8 “official” measurement.  Vernier calipers closed over both ends to show it’s raised off the surface for the best possible measurement.

Next was the string of metal tubing that Captain Redgoat gave me.  The silver S tube measured 58mm, .5mm more than what we saw from the official segment.

The L tube measured 84.2mm, .4mm above the 83.8mm from the card L.

I think a fair question to ask is: what could be considered “close enough”?  I would posit that a difference of .5mm or less is fine for most games and all casual play, simply because the difference is barely (or not) perceptible to the naked eye and that distance is likely to be mis-measured anyway due to slight shaking of hands when a ship is placed at the end of a segment, or the slight movement of a hand above a ship measuring the distance to see if a shot can be made.  In addition, I think the benefits of having accessories and convenient tools for players outweigh the slight differences, not to mention other elements such as bumping the table, “undoing” move segments and trying to estimate where the ship’s bow had started, and other accidental calculation errors.

However, I think it would be fair for any player playing competitively or for any kind of prize to request full enforcement of using strictly Wizkids official deckplate cards for all measurements during a game.

Perhaps the biggest takeaway is to not measure with full card lengths, as this gives such a player a decided advantage.  In addition, I highly recommend comparing any accessories you may have to the L and S segments on a Wizkids card, and trimming or editing them so they’re as close as possible to standard measurements.

Lastly, I welcome any community feedback regarding my measurements, if you have made your own and they differ, or what your group considers “close enough” as far as unofficial measuring accessories.
