Moomba Makai CAD drawing?

[HFarr]

Would anyone know where I could find a CAD drawing of the Moomba Makai?

[larry_arizona]

I doubt SC gives out cad data.

I have a new Makai on the way, and am trying to figure out what adjustments I might have to make to my cable lift (if any) in case my cross beams are spaced so that the stearn drive and mid boat stabilizer fins end up right on top of them.

You will need a cable lift with bunks that have no cross beams.....at least in my neck of the woods.

I took a side view photo of the boat and copied it into autocad. Scaled it pretty quick and made that work. I will be fine with the spacing on my cross supports.

Can you post some info and pics of what you did to get the pic in ACAD? I've run UG for years. Currently running Creo and trying to teach myself ACAD for some legacy projects.

Use can use AutoCAD Raster Design to get a rough spline in AutoCAD from any image file. The higher resolution image a contrast of black to whites helps get a better spline. Otherwise you could just import, scale accordingly and then trace the profile.

Out of curiosity what did you get from the stern of the boat to the center of the tower? I am not close to my boat so I cant actually measure.

Why is that? Our overhead lift has cross beams, never had an issue with any boat we've out on it.

Here is the CAD pic I made just using a profile photo. The dimensions shown are how my lift cables and 2x10 bunks were spaced. I just yesterday put the Moomba Makai on it. Not too crazy about how the Makai sits on them. I think I will make some changes. It had a crownline 240ex on it prior.

I just imported a jpg photo into autocad and scaled it (as close as possible, probably within an inch or so) close enough for my purposes just to be assured that my cross beams wouldn't end up right on my stabilizer fins or prop shaft. They don't, so I am happy about that. But I am not too happy with my width now, so I will work on that. The ideal setup would be to make a frame to hold the bunks just like my trailer setup. That would be sweet, but a lot of work and probably expensive and heavy.

How do you feel like your positioning front to back? In your CAD it looks like your rear lifting point is pretty close to if not right on the theoretical CG (I say theoretical bc no one can confirm where it is exactly but best estimate I have found is in between the axles on the trailer). It looks as if the front of your bunk boards are higher out of the water than the rears, is that by design? I am asking all of this as our lifts are being installed as I type this and we are putting the boats in them on Friday so I am very curious. I won't lie I am a little nervous but just having to be confident in our contractor.

This was when I first put the Tige on the lift on our shorter dock. I was struggling with water depth. It sat super nice on the bunks but had a ton of front over hang. No issues with a bunch of kids in the bow with the lift up. I mucked around with bunk positions under water with the boat floating above on a calm day.29525

TXsurf4,
You are right, I am not happy with how the boat sits on the bunks as it is. They are spaced for the old crownline that I had on it prior to buying this boat. I'm going to play with the spacing some next week and will post new pictures after I do. That cad drawing is a drawing of what I actually have now and not what I designed. By the way my boat has the exact opposite paint scheme as yours!

Understood. Are you un happy with the spacing of your bunk boards side to side or unhappy with how your boat sits on them front to back? Our color schemes are close to opposite except my metal flake is Raspberry. Pictures never do Metal Flake any justice. I love the color scheme on your boat!!! Is that eclipse black metal flake or black cherry metal flake?

[HFarr]

Black Cherry Metal Flake and Fire Red. I am not happy with the side to side or the front to back really. Well actually front to back is not too bad. I am going to widen the side to side about 6-8", and add another board to the top of the bunks in a horizontal orientation to give it a bit more contact surface area this weekend or next week. I am even thinking of adding a smaller wedge shape to the front similar to the trailer setup just to stabilize the boat a bit more and make it center on the bunks everytime I pull it in. We'll see if I can figure that part out. Again, the current configuration was for my crownline, which it fit perfect.

That is an awesome combo!! Ya let’s us know how the adjustments turn out. Our bunk boards are being installed Friday morning and we are putting the boat on the lift around lunch. Hopefully everything is spot on [emoji1694]

Shoot me some pics of the bunks and how it fits!

Yep got both boats on the lifts this weekend and it definitely feels good! Our bunk boards are 16 ft long and honestly the 12s that our contractor originally had would have been fine but with the boat being 24.5ft he wanted to put the 16s under it. The boat doesn’t even touch the front 3ft of them lol. As far as height we are 17” off of the supporting I beams which clears all the underwater hardware. Did you adjust your’s any? https://uploads.tapatalk-cdn.com/20210404/a145f95e795177db8e529ae54283cd44.jpg

Did you get your boards adjusted this past weekend?

I did but I'm going to adjust them again. It was a pain because the brackets mounted to the crossbars by drilling holes in it. New brackets will just clamp and give me more adjustability. I got the boat sitting a lot better and off of the chimes along the bottom of the hull. But it's still a little close for my taste, and causes a little bit of aggravation getting the boat lined up before lifting. I want to widen it up about another 4 inches to make it easier. Here are a few pics.

That was Chine by the way. Not chime! Autocorrect got me

I gotcha. Looks like you are making good progress. So you are getting new brackets? Are you not wanting to drill more holes in your beams?

Ever tried drilling 1/2" holes in a 3/8" steel beam while sitting in a john boat with a hand drill? The 8 I drilled the first time wore my a$$ out. I don't want anymore of that! ��

Did you get your lift all sorted with the new boards?

Not yet. I have the brackets, but just haven't had the time to get back on it. It sits fine like it is, but I have to spend an extra minute to make sure its where I want it before lifting. Maybe this summer when I start spending more time there.
