Incorrect control response on certain vessels
« on: November 15, 2010, 19:22:57 »

Hi, I am confused on how a few of the smaller vessels operate.

1. The water taxi, when you put this in astern, the controls seem to be reversed eg. you engage astern and steer to the right, but the ship moves to the left, with what little experience i have operating boats, i can confidently say that weather the water taxi is rudder controlled or outdrive, it should turn right when the wheel is over to the right. (this is not just when slowing down but when moving backwards)

2. The jet rib, i have the same problem as above with this boat, but also it takes a good 4-5 seconds for the boat to go from full ahead to neutral, so therefore a long time to get it into reverse, now i've never driven a jet boat before, and i know they don't have an astern gear but instead a flap that reverses the jet, but i'm pretty sure they must have some kind of neutral gear, which means you should be able to go straight from flat out to neutral, or straight from flat out to reverse, not like the boat on SSE which takes carries on accelerating for a while and then you need to build up reverse revs too. If my knowledge is incorrect on this one could someone please correct me, thanks

Thanks in advance

Hi Captain,

Things were rational in SS2008, but have become somewhat messed up in SSE, making it difficult for those of us who write instructions. The best advice I can offer at the moment is to observe and remember how each vessel actually behaves, and be prepared to repeat the process after each update.
The Vstp7 was intended to be Jacuzzi powered, but there seems to be some question about the mechanics of reversing.

A separate problem, or enhancement, in SSE is the introduction of ramping up/down engine response in the interest of realism. I think the feeling of many is that they demand realism, except when it makes things harder. For myself, I take it as it comes. But it does make it difficult to bring a ship to a dead stop until you have become familiar with the particular vessel. But, that is really the object, or purpose, of the game—to learn how to handle a wide variety of vessels.

Regards,
Marty

Hello Captain,
There are two main systems in order to sail astern with water jets, the traditional way, where the reversing flaps are hinged to the direction deflectors. The astern horizontal thrust is then at 180° from the ahead one.

In the second method, the hinges of these reversing deflectors are no longer attached to moving parts, but to the hull (indirectly of course). In this system, the rudder must not be changed whatever the ahead or astern deflector position, to turn in the same direction, clockwise for instance.
The Hamiltonjet website is not only very informative, but also offers a small game to demonstrate how the latter kind of jets work. The attached pdf explains it surely way better than I could do.

Also, the possibility to disengage propulsion at a greater speed faster than to build up thrust (ahead or astern) will be inserted in patch 1.3 .
Regards,
Luc

thank you very much for your replies, i have since discovered that the jet rib can be put into reverse immediately carrying over the revs from going forwards which makes sense for a jet boat, however i still don't see how any engine on a boat that size can really take that long to get to max rpm, anyway, i'll look forward to v1.3. Any idea when the first add ons will be out, i'm looking forward to co-op multiplayer :)

I don’t know if it is only on me. I have experienced this problem with  Orient Star, Esperanza and Agile (I will try and with other ships). When the ship is moving ahead even with a slow speed (3 or 4 or 5 knots) and apply astern to stop the ship, even 10% or 20%, she turns to starboard with a huge ROT (bigger than 100), making difficult to stop and moor the ship. In this case I apply 100% bowthruster  to port,  in case to stop she turning. It is a strange behavior especially for two screws ships.

also i think that they have changed the way the azipod thrusters work, on large ships and on the tugs, it used to be logical, which ever way you point the lever, the thrust is at 180 degrees to that, but now you point the lever in the direction you want to go, which i suppose is easy to understand but harder to use for maneuvers, i don't know what the proper way is however

Gentlemen,
I think the latest idea is to follow IMO regs that the principal steering control should be intuitive—that it should turn, or point, in the direction that the ship will turn. This, of course, is not necessarily the direction of thrust.
When 1.3 is released, I hope to update the document on controlling AZ drives, but for now it is like shooting at a moving target.

MVSmith,

I understand how the controls are different now.

But I'm still not understanding whether SSE intended to have things "reversed" on purpose of if this is going to be the new arrangement from this point forward?

It's really difficult to operate the Orient-Star Azipod system the way you suggests.  While it may sounds very easily by "pointing towards the direction you want to go," it really becomes counter-intuitive when executing precise manuevers such as docking and turning while reversing.

Hi Azipod,

If by “SSE” you mean VSTEP, I’ve given up on trying to figure out what they may do next.
I wrote the monograph to describe the operation as it was at the time of writing. There is no point in revising it until 1.3 is released and I know how things work then. Neither is there much point in speculating on how things may be in 1.3.

Regards,
Marty

1.3 will be released after it is completed and has been tested.

LOL!  What time frame are we talking about here?

Until testing is completed it is not known how much additional work may be necessary. It is simply not possible to predict when it will be ready to release.
The alternative is for them to give a date and release it then with some bugs still to be corrected in a later release. You have seen how well that has worked out for them.
