ah so we have an accord. Now just so you know i have studied heavily on how to steal ships. If a ship does not have a double chest and has no signs yes it can be towed but if you attach another ship to a already double chested ship then you would just be getting that one stuck too. This is because when 2 ships merge they become one ship technically and then the double chest counts for the whole thing.
Raise your glasses, raise them high. Draw your swords, stand or die!
