If you use a chain, the damage is 2d8+7, but you can try to reel the target in. It will have a dice check that will depend on the thing you try to reel in. Though if the thing is larger than your boat, then you are actually pulling yourselves to it. The chain is the weakest point in the design, so it will break before you lose the ballista.
