Hoy,
Well, Oceandream i'm more sure that an fully loaded vessel is more handy to handle.Even with all the ballastbunkers full, your ship will not go as deep,as with the cargo itself.
Mostly the wind will make it difficult for you to handle a vessel in ballast, or empty(inlandvessels and smaller ships).
The only thing you have with fully loaded vessels is to keep an i on your speed,when you need to manouvre,mostly this will be assistated with tugs.
This idea makes it maybe more easyer for the modellers,keep the normal model,only with the other parameters.
It makes sence to me.
Thanks for the reply's,guy's!
