    Default Speed boat simulator in development

    Hi, folks. I'm developing a speed boat simulator that some people here might find interesting:

    Design it, Drive it: Speedboats

    While it's not for sale and there's no demo yet, hopefully in the next few months I'll have something people with a decent gaming rig can try for free and buy at a reasonable price.

    I'd love to get some feedback from you guys. Let me know what you think, you might even influence how it develops! Feel free to leave comments and questions in this thread or on the web site itself.

    Mods: If this isn't the right forum for this, let me know and I'll delete and repost this somewhere else (or you can just move it as you see fit). I figured the "general boating discussion" might be as good a place as any.

    Thats pretty cool!.... think you can make it all work on a vdrive type inboard boat with cav-plates and all working to the same physics you already designed into the program???? maybe a better motor sound would be appropriate too!! lol

    Thanks, glad you like it.

    I don't know inboards very well. Is a cav-plate an adjustable plate similar to a trim tab in principle? Is it adjustable from the driver's seat?

    If so, yes I could add that pretty easily along with trim tabs and so on if people want it. The hydrodynamics all run off the boat's geometry, so I can stick adjustable plates and flaps wherever you want. Right now I'm just playing with outboards, so it's just got an adjustable jack plate and engine trim.

    Probably the first release of this will just be outboards like you see in the videos. If there's enough interest in the simulator I could add inboards later, I suppose...

    Engine sounds: Yes, I'm using a V8 4 stroke sound in some of the videos that's just been sped up to give it the same base frequency as a V6 2 stroke. I'm working with a professional sound guy that does audio for a lot of the race car sims out there. He's trying to hook up with somebody to record a V6 2 stroke so it sounds more like a boat than a car. Still though, that V8 sound might be good for inboards or jet boats maybe if the sound was played at the right speed?

    This is a picture of the rear end of what is known as a "true flat-tbottom" v-drive boat. It shows you the cav plate and the hardware and it basically works from a pedal at the drivers seat. There are many other v-drive hull types; "runner bottom", "gull-wing", "ski-V" etc but they all use the same idea of cav plate operation for 'trimming' the boat.



    How it works: The driver pushes down on the pedal on takeoff to make the plate go downwards, which makes the nose of the boat trim downwards. as the boat comes onto plane, the driver releases the pedal to trim the attitude of the nose as needed to the speed he is going.

    Well that's neat, thanks for explaining it. It's a bit like a giant, pedal operated trim tab across the whole back of the boat then? Yes, I should be able to do that if I get into those types of boats at some point.

    That's pretty cool I can see all the math that went into the design. Extremely good work.

    Thanks! Yes, quite a bit of math in this one.

    New video:



    Hydro would be cool. At this point around various forums people are asking for every kind of boat in existence, it seems everything but the ones I actually planned on doing first.

    Here's a new vid showing some effects of jackplate and trim settings. There's some chine walking here as well:

    Forces view showing aerodynamic and hydrodynamic force vectors. This also shows a blue outline where the boat touches the water to visualize the wetted surface area of the hull. This is handy for tuning the hull shape to get it really flying.

    Can I ask you guys which engine sound you prefer? The red boat or the blue boat? Neither one is really a set of recordings from a 2-stroke outboard, but these are my only options right now so it'll have to be one or the other.

    Wow, very cool, glad I spotted this thread.

    I'm a software guy by trade, and I make games on the side. What engine are you building this in? Unity, Torque, Unreal, something else? Do you want an extra programmer? I've often thought of making exactly what you have here, so I would definitely love to get in on the project!

    Edit: Question about engine could have been quickly answered by actually reading your site. I'm familiar with Unity and have done some dev in it. Let me know if you want some assistance.
