The authors of Mount and Blade 2 Bannerlord continue to prepare for the release of the War Sails add-on. They recently released a development diary in which they showed a variety of game models.
The screenshot on the left shows the types of sail geometry - square, Latin, hybrid.
The developers clarified that sails cannot be replaced, but can be upgraded, improving some parameters:
«Square sails provide rapid acceleration and work well in light winds, but perform poorly in [strong] winds.
Latin sails catch the wind from different directions, providing higher peak speed and better maneuverability, although they result in slower acceleration and less responsiveness.
Hybrid sails combine both types for more confident handling in variable winds. The type of sails of a vessel is fixed in its design and cannot be changed, but upgrading the sails improves driving performance within these limits».
The developers also showed several ship models:
