Should you be able to pre-measure the "boost" action, in the same way that you are allowed to pre-measure the barrelroll?

And, if you dont have the room to do either one, do you get to choose another action, or is your action"lost"?

I'm a bit curious to this as well. But as it is more of a planning and you have no idea whether or not you CAN perform the action, I would assume yes. I would like some other confirmation (rereading the rule book in a few days) as to whether or not you can. But I don't think you would lose your action if you measured it or not.

Well, you kinda have to pre-measure it as you're not allowed to Boost into an overlap (obstacle or ship). It's on the reference card.

You can definitely premeasure for barrel role before comitting to this action (says so on p. 8 of the rule book). That means you don't lose your action if performing a barrel role won't work. I'm guessing the same would be true for boost given, as Cid_MCDP notes above, the card says a ship cannot boost if doing so would cause the ships base to overlap with anything.

Question related to topic-

I know there are other games that disallow things like pre-measuring and have "Gotcha!" mechanics built-in that actually penalize a player if they make the wrong decision (ex- in 40k, you declare a target, then measure distance to shoot- if the target unit is out of range, too **** bad- you can't shoot at anyone else*), but off the top of my head, I can't really think of any similar "Gotchas!" in X-Wing.

Are there some and I'm just not remembering them?

*Note- I mainly played 40k 4th and 5th ed. This rule may have changed in 6th. Apologies if it has.

What about premeasuring BOTH boost and barrel roll before committing to either action? I had an opponent w/ push the limits on Soontir Fel during a tournament that laid out a spare base for the barrel roll, then placed the boost template at the end of the barrel roll base, and placed another base at the end of the boost template. I didn't really think about it then, but shouldn't you have to comit to the barrell roll or boost before you chose to do the next maneuver?

Yeah, because the Actions aren't happening simultaneously. He could pre-measure the first, move his ship, then check to see if he still wanted the second Action, but he shouldn't have pre-measured both at the same time.

Somewhat related comment, note that none of this discussion applies to Daredevil. Daredevil is defined as being a maneuver, & pre-measuring maneuvers is against the rules.

As far as I'm concerned, the only prohibition against measuring is on Page 6 of the rulebook, and it specifically references the Planning phase. So, as far as I'm concerned, if you're not in the Planning phase, you can measure whatever the heck you feel like. If you want to lay out multiple spare bases and movement templates to plan a series of moves, why not?

Heck, you could do all your premeasuring as soon as the Activation Phase is complete, if you feel like tipping your hand for next turn.

I agree with Grimwalker. The rulebook says " During the Planning phase , players cannot use maneuver templates in order to “test” where ships will end up." Once the planning phase is at an end, measuring is a very important part of the game, as you are not allowed to take many maneuver based actions that will cause overlap.
