Missing damage values for ship weapons in the companion

chaos king

I am how much damage the ship weapons do because it seems that the damage values are missing in the ship rules for the runequest companion.
Well, the damage done by rams is given in the ship description section.

Arbalests don't really do damage to ships, they are anti-personnel weapons. Ballistae and Springals should do damage to Structure Points.

I would say that Ballisate should do 1d3 Structure Points damage, Springals should do 1D3 - 1D10 damage.

Fire would do 1 SP damage per turn for each size category. Monsters would do damage depending on their SIZ and STR. Storms would do Seaworthiness damage, as stated in the description.
