Scripting Help - Moving Boat?

I’m trying to make a boat with a lot of objects move down a sewage tunnel.

Is there a way to group all these objects and move them at once with the boat not messing up?

I’ve tried wielding the boat together but the game does not seem to like this.

I have no idea on what to do. Any Forgers know how to do this?

(Kind of like the train on Survive the Underground)

unless theres a cheat to making it easier, just individually set the blocks to move the direction and distance you want.I assume youre looking for the cheat, but if welding and grouping cause problems (ive seen what a grouped object does it aint pretty) then there probably isnt an easier way.
