Well, we had fun! The ship was crippled during the evening meal, and after some confusion thingswent as (I) planned, with the engineer knocked out and the captain smeared against a corridor ceiling in a -6G inversion.
My youngest son, 11, had Vacc-2 and was put up for the hull crawl by the 14 year old. After I statted out the rolls, he got scared and had to go to the toilet

))
Roll 1D +2 for Vacc Suit skill every minute. Roll a total of 18 in 7 minutes. If he rolled a natural 1 he would lose control and float free, touching the bubble. Ingeniously, he strapped magnetic boots to his gloves and groped his way across the hull, still attached by a tether to the airlock.
Unfortunately for me, my son rolled 6, 6 and 6,. getting to the drive room hatch in 3 minutes! So ... I had a computer controlled repair robot come up out of the hatch to defend it. A short time consuming fight occurred, during which my son's arm went wide and he lost his hand in the jump bubble. But he survived, got into the drive room and keyed in the deactivation code in the last minute. And we'd just been joking about how movies always have the 'two wires to defuse the bomb syndrome, and the countdown always stops on 1 second ...
Meanwhile my 14 year old decided to rescue Mal Reynolds, sorry, the captain. He found a null-G cargo harness and wore it, then used it to go into the -6G zone with a +4G bias. With help from the engineer he hooked on a line and she reeled him into the safe area of the ship.
Job done. A new vat grown hand will cost my 11 year old 4,000 credits, which he isn't so keen about! But they learnt alot from the captain and crew about getting a ship of their own.
And he got onto the interstellar news network by being the first person in the Human Republic to do an EVA in jumpspace!
