Sail War - ProkopHapala/SimpleSimulationEngine GitHub Wiki
To Do
Important and not problematic
- automatic engine to compute ship polars
- auto-pilot which would enable handling larger fleet
- ship stability 2D (xz-plane) - by cutting triangles by line ( area of whole triangle minus area of trimmed tringle, do not compute the quadshape rest )
- islands - mostly just to make environment less homogeneous
- different types of shots - ball, chain, grapes
- damage model - hull damage (differet sides), sail damage, crew damage
- Raking fire - https://en.wikipedia.org/wiki/Raking_fire
- phenomenological 3D tilting (heeling) - motivation e.g. A second disadvantage of the leeward gage was that in anything more than a light wind, a sailing ship that is sailing close hauled (or beating) will heel to leeward under the pressure of the wind on its sails. The ships of a fleet on the leeward gage heel away from their opponents, exposing part of their bottoms to shot (https://en.wikipedia.org/wiki/Sailing_ship_tactics)
simple but unsure
- sea currents - again to make environment less homogeneous
Big modifications
- consider ship tilting in 3D, stability, buoancy and inertia of manuevers
- 3D view and models ?
- make dynamic library in python to simulate the ships

A lateen rig rises better towards the wind and is far more maneuverable, allowing tacking and beating to the wind. Although it is more difficult to tack with than the Marconi- or gaff rigs, it has a better aspect ratio than the square rig.
- latin rig - However, it runs poorly. Thus, the Spaniards often re-rigged their vessels when they ventured out of the Mediterranean into the Atlantic, where the winds are constant and a square rig had the advantage. https://en.wikipedia.org/wiki/Lateen#Comparison_to_square_rig
