Worked a lot on tuning the params, wind strength, water resistance, mass, lift, momentum. wind speed is now 10. boat goes up to 10 in optimal conditions, makes sense. but going 10kts seems to be too fast still, probably we need to scale the whole world up so 10kts looks slower. also acceleration is way to quick. Also added relative wind arrow (is more important than normal wind indicator). Particles temporary disabled. Added the keel sidewards retardation force again to avoid drifting. LUT Sail force is only applied if not isInIrons. Added a (weak) wind hull force to the ship, this is mainly there so you can go slowly backwards if you messed up turning.
