Just a recommendation to have the option for a variety of different sail options for function, not just cosmetics. For instance, each ship would be able to support various sail/mast options based on ship size and type, using a point system.
SPEED SAILS: Increases overall speed by maximising the wind caught when sailing with the wind. Takes penalties when trying to sail directly into the wind or tack through it.
HANDLING SAILS: Increases maneuverability by catching more wind in the sails from any direction, and being able to move moderately when sailing against the wind.
WEIGHT SAILS: Improves general speed and maneuverability for ships laden with cargo or cargo racks.
Ship Restrictions and Costs
These would be available in three sizes: Small (1pt), Medium (2pts), and Large (3pts). The ship type and size would determine what various sails and masts they could support.
WINDCUTTER: Support for up to 2 masts for a total of 3 points. Could support small sails, a combination of small and a medium, or 1 large sail of a single type or various types.
SEASTRIDER: Support for up to 3 masts for a total of 6 points, allowing for a maximum of 3 large masts of a single sail type or a combination.
WARGALLEY: Support for up to 5 large masts for a total of 15 points towards any combination of large sail types.
I also submitted this as an Idea, but just had a lot of details in relation to it so also posted it here for discussion.
