Hi hiran,
Some ships, (small ones) the two pilot boats, Arrie Visser, Billy Greene and the water taxi are driven by Hamilton Jet drives, these vessels when put into reverse gear react in the opposite way to normally driven vessels. They will swing in the direction of the forward steering positions. This is a little confusing until you get the hang of it. most of the other vessels are more or less self explanatory I feel, but a little experimenting in "Free Roaming" play will soon give you the information you desire.
Ships with two thrusters, one forward & one aft, show the forward control on the left, & the after control on the right.
The post I give a link to above, lists the drive systems of all the vessels in game. A little extra research on the type of drives listed will give better explanations than I can.
The "Oceana" has four azipod drives and two forward bow thrusters. The centre azipods are fully rotatable through 360
0 whist the outer two are fixed drives. The "Zilvermeeuw" is exactly the same as the P6 patrol boat.
The two inland vessels, "Deo Favente" & "Mare Australe" have very good steering capabilities which make them very easy to handle in confined places. The tug "Bugsier 2" has drives forward of amidships so she will go in the direction the Controllers are pointing, this make her a tractor tug. The "Cratus" has drives aft of amidships which causes the sternto be pushed in the direction of the controllers, thus the bow swings in the opposite direction. This system is known as ASD drives.
I hope I have covered most of the vessels now.
Regards,
Angus
