CT Only: Hijacking Attempt on an 18+

[ThrorII]

Something I'm not sure I've ever noticed before: The rules state that a ship has a hijacking attempt if the referee throws 18+ on 3D. Now, 18 is the maximum roll on 3D, so the "+" implies modifiers. Except nowhere in Book 2, or The Traveller Book, do they mention any modifiers to this throw.

If you use this rule (throw 3D each trip, with a hijacking attempt on 18+), what modfiers do YOU use?

Do you...
...add a modfier for a low law level of the origination star system?
...add a modifier for high credit speculative good purchase?
...add a modifier if the crew doesn't stow passenger weapons in the ship's locker?
...add a modifier if the ship is undermanned?
....something else????

From what I see It's just a straight 1 in 216 chance.
Which is actually fairly high when you consider that average starship will make 960 jumps in it's 40 year "lifetime"
So a little under 4 1/2 hijacking attempts over the ships lifetime.

Add a +1 if Ine Givar are known to be in the Star System.
Add a +1 if Pirates are known to be in the Star System.
Add a +1 if it is an Oppressive World.

I never felt the need to bump it up or even bother to roll it. Hijack attempts would be a ref event for me.

If I did do DMs, it would probably be 20+ on 3d with at least 2 conditions to make it possible.

Hijack attempts would be a ref event for me.

Hijack attempts are an event for me when the dice say they are.

And then I fit them to the circumstances.

Refereeing by abductive reasoning.
