I got this ship but one problem when i rotate my turrets it always capsizes or flip pls help me

I am great at boat making and heres my basic quick tips that you should learn
1:make it bouyant(obviously)
2:two factors to make it not to go circle was make shure the bouyant part was imagine bouyancy was the leg of table and mass was the top of table, the further away the legs can strech , the longer you can support it stability when toggles , also try to avoid the com got higher in sea level
2.2: the other way to support it was, think of it like a bottle, when you hold(pinch) the cap of bottle and lift it, if you shake it the nose will maintain at 90° angle (unless if your bottle wasnt ave enough water on it) at its elevation, and you know why this happens?.. its simple, your hand counters the gravity that pulls the bottle so it wont fall but therefore the part of volume of bottle you was holding was too shallow and far to the center of mass and center of mass will be forever attracted to gravity at all cost, so even the bottle wont fall at groun because your hands (exept butterfingers) , it will still find its naturaly way to get closer to where gravity wants it to go until it reaches its closest point at greavity source( or ground) without chqnging its distance from your hand to the mass so if we asume that the cap was front and the center of mass was the end , make a line from its two point , by only using 2dimensional scale like horizontal and vertical , if you includes the bottle in your 2d , the nose will end looking up at 90° horizontally or 0° vertically as the com has reach its nearest distance at the gravity while being suspended by our hand. and wahts the purpose of this bottle example? ... tip= bouyant part of the ship and hand=water while com was the mass making it stable. to be honrst this is the longest tip I ever write
3:use engines as turning tool . how? make the engine look at the side instead of front and change the parts property by spamming the " throttle" button to change it to "roll" or "yaw" or other buttons that you intentionally use to turn.
3:2 if you got smaller ship for your engine to fit in , you can use the gyroscope by increasing the yaw power depending how dense your ship/boat was,and also set gyroscopic stability to 0 so you wont end up looking at the same place you just look, also you can use RCS systems but it will requeres vtol engine
4: never place engine beneath water , [quick reason] " so maneuverability wont end up as a piece of shit
5: use fuelsage to change com and to change shape quickly and also as a compart

@AeroEngineering @XVIindustries can one of you help me with my boat, it has the same issue of drifting, the one on my page will work, or i can give you the most updated version i have. (it mostly just has more weapons, but does have a slight keel change

Hahah @Cedy117

It's a fishing triller I got it going good now I jut need it ballenced out because it tends to flip on turns but I'm busy with halo 5 for now @XVIindustries

I am good with boats, what do you need to know? And what type/style are you building because that also has a factor,

Look at my boat just click my username to look at my planes and boats

I once built a jet boat and it worked fine. I had only air-rudders on it. When I tried to add a keel, it got screwy on me.

@Cedy117 ok

Thanks for the help I'll definitely keep That in mind @Delphinus

Nvm I got it going I just added a large keel and it seems to work ok I will post in the next few days it's a steam troller @AeroEngineering

Actually, just upload the boat and I'll fix ut

I can probably make it work

Try lowering the center of mass, making the boat sit lower in the water, and make a classic pointed hull. If that doesent work, then I have no advice. Good luck!

Ok I'll go have a look @TheLatentImage

Yes i know about the rudder but my boat still spins out @Skua

I haven't messed around with boats a whole lot. But the successful watercraft I have made involved having a decent sized fin going down into the water to keep it wanting to go straight for the most part, unless you're turning. Check out the fin on the bottom of my shark if you need some kind of reference. I hope this helps you out buddy.

I've not got much experience with boats, but a rudder that sits under the surface of the water at the back - just like the vertical surfaces you usually use on aircraft, but upside-down - usually helps with that issue
