Plate Aluminium Wake Boat - New 5 Blader Prop

Postby MACH6 » Thu May 20, 2010 10:12 pm

Hi All,

I am after opinions on this boat that I am making. It is a 6m Aluminum Bow Rider Wake Boat with a 5mm bottom and 4mm sides. It will be running a Mercrusier direct drive 350 chev (Approx 260hp) with a 1.5:1 reduction and swinging a 14&1/2" Dia X 18" Pitch Prop.

Here are some Pics of it in production.

Do you think it is a too shallow "V" in the arse?

Cheers

fvcking mad bastard!!!

I'm no expert either... but from all the hulls I have seen, it does look a bit flat.. also, I noticed the shape at the sides where it kicks down similar to a malibu "diamond hull" as seen on this page:

http://www.themalibucrew.com/forums/ind ... cles/hulls

from what I can see this creates more surface area or displacement, assisting the boat to sit higher out of the water, which would reduce wake size.

not trying to put down your efforts in any way though... it does look amazing!

That looks awesome. As said above, the lip on the outside edge will give you lift, hence less wake. Put some massive under floor ballast tanks with fast fill valves like on the MB's, and it will help. And yes, the angle does look a little flat compared to some boats, but it will be interesting to see how it goes.

Keep us up to date with your progress!!

you have the right idea, but it also puts a pocket of air under the downturns

If it doesn't have a good wake, then just do what Malibu does and put a wedge on it!!! :D :D :D :D

Lower deadrise hulls generally can take a LOT of ballast without crumbling the wake. I think you'll be OK.
Nice project :!:

yeah i dont think the 'V' is too flat.....comparing to other wake boats

but agree with sheelos about the outer edges of the hull creating lift.

but as said above, it looks un-real, i look forward to seeing the project unfold.

Love your project man absolutely ballsie effort. Building a boat from scratch.
Hull design is a very tricky issue with most boat manufacturers performing many hours of water testing to get there hulls right any even then people have different opinions.
Looks pretty good so far I guess you are copying your favorite wake hull to start with or similar and thats probable about all you can do without a huge budget of money and time for R&D.

As others have said can't wait to see you progress through this project.

Could call some of the aussie manufacturers they may be willing to share some info, Maybe?

Good luck.

Good project mate.!

I think the flat rear V will be OK. I would be concerned about the small angles out the outside though. Maybe consider changing to a relief in this area AKA nautique.

I have never seen a inboard with these wedges on the hull. outboat yes.

I have seen similar projects on US web sites. from memory the boats are really light & need quite a lot of ballast.

Also prop may be trail & error.

Keep the updates comming.

Thanks for the advice,

I have been looking at the planing/lifting strakes that other boats have, and I am trying to decide if I have put mine on backwards eg, short side of the angle on the outside instead of how I have put it. But I feel that the way that I have put them would be more ideal for directional stability and help prevent side slip on turns rather than to lift, as I think an odd 8 sq-Mt of planing area is enough lift.

I am also looking at making a wedge to hang off the back, any ideas for crazy wedges that I can slap together out of alloy?

Also do you think this boat would benefit with a center fin?

This is going to be great to see progress. I have to agree about the angles on the outside.
I'd have a close look and the 5th photo down on this page )you may have to be a member to see them)

http://www.the2001.com/index.php?name=P ... hull+photo

the SN2001 is a lighter boat like yours will be and still produces an amazing wake.

good on you for having a go!

One thing i'd like to bring up is the angle of the v towards the bow of the boat, it looks pretty flat there and just as a guess if you had more angle there it would help with tracking and cutting through chop. The big channels on the sides at the back will lift the boat but remind me of a tige' 20i they can make a pretty good wake with about 800kilo's in 'em having said that they are very wide boats yours may not need that much weight as it seems narrow.

Ouch, I'm with Careless. Just had another look - she'll be a rough ride in choppy water. It looks a little like a punt on steroids :lol:
