Damage is recorded as hull and mast hits. Each mast hit reduces a ships speed and each hull hit reduces its combat power. After 3 mast hits a ship is dead in water and will not receive any more movement points. Ships which have suffered more than 6 hits of any type may sink or explode. Boarding is possible but strongly discouraged by the rules since a boarding attempt can easily result in a hard collision and heavy damage to both ships.
Wind strength is divided into flat calm, light, brisk and strong wind and storm.
Flat calm prevents all movement and thus action, while storm will immediately end a battle. The crews are too busy keeping their ships afloat to fight. Crew qualities are rated as green, poor, average, professional and excellent. The command rules reflect the poor communications of the period. Ships of the line must normally conform to the manoeuvres of their flag ships and may only move independently when in gun range of opponents.
