As someone 'here' stated, the front 'V' is going to be an issue once we are up on plane. slapping the water instead of cutting. There is also going to be an issue of cavitation we'll have to address later. (because of the overall length)

They make software called computation fluid dynamics, CFD. Basically designed to simulate fluid flows. I know some finite element analysis, FEA software packages can model things. Good luck.

Noah, I was making fun of myself and my lack of knowledge with this post.
You must fit the over intelligent, lack of humour profile.
Like I said, good luck with the project....

In retrospect, that would have the right way to go. I've been designing and using 3DMax to model ideas for 25+ yrs. However, it's mostly been in the Architectural field. Just recently, we've attempted to make a PWC that would act more like a wakeboard. So, assuming a 750cc on a vehicle weighing alittle over 200lbs, (prototype built) would atleast throw it up on plane. Seriously underestimated the hydrodynamics involved. Now, I know what 'living' the adage "Design is always in a fluid state of change" means. (pun intented)
I suspose, ......cool
hey noah you prob already know this site but its where i get a lot of design software to try. these are full versions just the legality of its a little questionable. theres only been a couple of things they didnt have and i sent them an email and within a couple of weeks they put it up.
if your a geek as i am you will love this site!!!!

Dealing with fluid flows is a complex study. Flows can go from laminar to turbulent due to a slight change. I took two cources called fluid videos. For an hour each week we would watch videos on fluids. The coolest one was when they would use high speed cameras to take slow motion video of cavitation on a propeller. I don't think you are goignot get much help on here without some photos, detailed drawings, or videos of your exact problems.
And i understand that. I'm keeping this on the down low, because we got alot of time/money invested in this concept. Mostly sweat equity. But Alot of the feedback has been really good, confirming next steps.

What about a seadoo jet boat. 110 HP single pump 12 foot long and 7 foot wide. The actual part that is in the water is shaped exactally like your picture. Have you ever seen a small jet boat upside down probably not but you can imagine. (I do some work for a fiberglass repair company that flips boats and fixes the bottoms) But anyhow what I meant is that the waterline is a lot wider than it is long and with the center being deeper than the sides. That is what I was talking about.
point taken.... I've never noticed how wide that jetboat is. The idea w/ the original design was to 'snap' the steering, and do a 360 spin, like a wakeboard.
If it has a deep 'V' hull that ability would be gone. So, now, if I 'clip the wings', it's becoming more like the original 650sx hull profile. The 'V' will make sense, but only towards the front.

I think it could still plane if it was deeper in the rear than the front. But I see the push problem also.
On a side note kinda of a hydrodynamic learning experience. We played at the lake 5 days a week with the ski boat but got bored so we used different pieces of wood and odd shaped things to tow behind the boat. The best thing we found to play with was a piece of wood about 2' by 3' oval and we would hold the ski rope against one of the 3 foot sides with our thumbs like a knee board and press the other side against our waist. We would troll about 6 to 10 MPH and nose the front in the water. That piece of wood would take you all the way to the bottom of the lake then you would angle it back up and resurface. We learned quickly to wear gloves the rocks on the bottom would take the hide off of your knuckles. You could stay down until you ran out of air. Kinda of a cool thing to play with.
Ok back to your regular scheduled programming.

sorry, there is no question about it being illegal. Seems silly to pay any $ for pirated software.
In any case I don't think any PC based CFD software will solve this problem.
Given a couple of years learning time and super computer access maybe..but I wouldn't even bet on that.
