Ship Repairs
Source: Astral Adventurer’s Guide p. 25
Nonmagical repairs to a damaged ship can be made while the vessel is berthed. Repairing 1 hit point of damage to a berthed ship takes 1 day and costs 20 gp for materials and labor. Damage to shipboard weapons can be repaired just as quickly (1 hit point per day), but at half the cost (10 gp per hit point).
The mending spell is a cheaper, less time-consuming way to make repairs. Casting mending on a damaged ship or shipboard weapon restores a number of hit points to the target equal to 1d8 plus the spellcaster’s spellcasting ability modifier. The target can regain hit points from that spell no more than once per hour.
