In Lost Tribe scenario, my very first B18 Unstable game took 600 days to launch the ship. How did everybody else fare in regards of time?

The research penalties for tribal make it a long play through. Luckily you can travel out of the colony sooner with pemmican. It might be more viable to travel to the ship than build one.
I think that will be the goal for his next tribal run ! :-)
~ 7 years with one bench, the remaining colonists are going for the landed ship, another 7 years, they're chilling on the road.
