Here are some lines that I laid down before the lines on poll. I felt that I cjould lower the deck down about a foot and it would look better but then I desided that it looks to much like every other production cat out there so I Shitcaned the operation.

Here is a shot of the cat on poll in early stages on planing as you can see I toyed around with the nose treatment in this perticular shot. You also will notice that the interior is drawn in I plan on mving the front seats back 6" to 12" inches away fron the dash.

I would love to read any feedback you have on this design good or bad.

[Jungle Boy]

I guess I'll jump in with my thoughts. Have you ever built an aluminum boat before? You must have experience with welding the stuff or you wouldn't doing it. From my experience with aluminum boats; my buddies own Eagle/Harbercraft and Outlaw Marine, both of which build aluminum boats. The look of your boat is good, but getting it from a drawing to floating is a lot of work. These guys use jigs that they weld or through bolt the sections as they are welded. To fail to do this, it will warp and look like shit. The pieces are preformed in a break and then tack welded in different places to keep from warping. It has taken these guys many years to make a aluminum boat look like it's made from glass. The early boats (20+years ago), really looked rough and every one was different in the way it handled. It took many years and many boats to get the right bottom to make them run fast and turn good, which is many dollars. I suppose that I'm soundling kind of negitive. But if you are into it, I guess the only thing that is holding you back is the first weld. Good luck. Here's my tin tub. Eagle Racing 21' Tunnel

[jlnorthrup122]

Thank you for Your feedback Jungle. Your boat pictured here is beutifull the first time I saw your boat I thought it was glass. I have a few years of metal fabrication. I plan on building this boat with a truss every 2 feet and I am looking for a stripped down camper or mobile home tralier frame (there are lots of em around here) and throw up an angle every 2 feet on both frame rails then level it out and stike out a base line on the angles for locating truss position. I will bolt on every truss in its position on the hull in a maner in wich it will be upside down and plate it. I am very aware of the obstcales in wich I will encounter. I have finnished metal for a number of years And I hope that I am good enough to make this hull look good.
Is your hull powdercoated or anodized. and how do you like the finnish on your boat durability wize (I can see that it looks realy good) Thank you again for you feedback

[Jungle Boy]

Sounds like you got a good plan together and will do well at it. Mine is just painted, base and clear coated (4 clear). It gets scratched up from dirty boots, trees and branches, but that's river boating the way we do it. For a lake type application, it would stay very nice, I think. It always freaks me out when I go to the lake and go to jump in a buddies lake boat with my boots/shoes on and they freak out. We have a little less respect for the finish than most boaters. Keep everyone posted on your progress. :cool:

[jlnorthrup122]

Jungle I will definatly keep everyone interested up to date with this project. I plan on starting to build the truss's this comming weekend I hope. I still need to go down to the architect supplystore and get another roll of tracing paper (for rough drafts) and More velume ( for Diazo/blueprints) soes I can continue on the frame up designing and calulations. Thanks :)

[jlnorthrup122]

come on people it can't be that bad

[Jungle Boy]

You'll have a hard time with it here. There are only 4-5 tin boat guys here. We have failed attract much interest in the aluminum boat scene. I don't worry about it a whole bunch. I just like to see the photos of the nice folks here and get jealous of their year round good weather. I still like the type of boating that we do over floating around in an over populated lake. But don't be discouraged. Build your boat and the people will come. :D

I just got all the frame work layed out and will definatly be buying material monday I would post some pics but my computer is running real slow.

[wfodude]

Hey man...it looks like it will be a sweet boat if you can finish it smooth...Good luck.

[HOSS]

Its gonna warp when welded. For this you can dog it. What gauge sheeting are you using? Bolt in a truss? I wouldn`t. Takes away the integrity of the truss itself. I wouldn`t bother with warpage. It will be a lake boat. Finish it off with micro balloon then paint. It is light weight.
Someone on here had pics of a 80` aluminum cat. It was a bare hull. No rigging at all. Yellow. If I won the lotto that bitch would be mine. 150k! If I remember correctly. It even had a trailer. I`m surprised that the Navy hasn`t looked into this very hull as a design for the replacement of MK-V`s. Put 2 Detroits, jet driven in that hull and I really do see triple digits as a realtiy. I believe the hull incorporated 3 steps. If someone knows about this hull please post more info. Was at a yard in Canada I think.

That cougar`s been for sale for a long time. They have 2 on the lot.

Its gonna warp when welded. For this you can dog it. What gauge sheeting are you using? Bolt in a truss? I wouldn`t. Takes away the integrity of the truss itself. I wouldn`t bother with warpage. It will be a lake boat. Finish it off with micro balloon then paint. It is light weight.
I have been worken with metals for about 8 years now don't sound like a long time but the cheapest project that I have ever worked on was about $4million so as you can see I have worked with some very pickey people. I know all about warpage I have already taken this into consideration and have a 3M rep working on improving an existing product. I know I can only minimise distortion of the sheeting and have a few years experience of treating this condition. I will take the micro baloon into consideration but on this particular project I plan on using transperent candyapple green for the main color leaving the mirror finnish exposed to form a mirror trible flame design shooting up from under the waterline so you will be able to see the high mirror finnish through the paint and many coats of clearcoat. I only plan on useing bolt on clamps to hold the truss' to the fixure they will not penatrate the truss'
Hoss I don't want you to take this reply as snyde I just don't have a personallity today I am dealing with computer problems and my kids are on the rampage. but I did get rid of that rediculouse sig pic though. I would be very happy if I could get 130 MPH out of this boat with about 900 HP from a single big block with a duel shaft drive system. I do plan on finding the gravity center after it is complete before locating fuel cell placement the fuel cell will be dead center on the gravity center to prevent changing porposing conditions. No matter what any one tells you fuel cell location is an extereamly important perfomance facter that is often overlooked by toolers/desingers. That is why cad/simulation programs are nice to have or know your math and formulas for calculating things such as Center of gravity wetted legnth @ plane @keel('s) @Mean wetted length @Chines, displacement @ max load displacement @min load trim agles dead rise agles affects speed length ratios draft drag hp mph porpsing dynamic lift frictional resistance. These are just a few of the factors you need to design a sucesfull hull it also helps to check out other succesful designs that already exist. :cool:

[HOSS]

Cool! You had me worried. 4 million.
I think the cheapest yacht I worked on a Trinity yachts sold for 28 mil. That was with about 6 mill loss. Other than that a few MK-Vs, CPBs, Venezuelan Navy patrol boats, some lame ass LCACs for US and China, AGOR, Navy SeaLifts and LPD-17.
I see your point. 3M should have a quick fix.
But seriously, look into micro because its strong as steel (when mixed right at temp) and light weight. I`d look into it then decide if its for you. But at 130 it`ll probably fly off. 3M makes some awsome products. I`ve never built anything for those speeds on water. What gauge will the hull be?
Oh by the way, I`m a little tense. Doing tile floors in my house right now. This really sucks. Would micro stick to morter? :mad:

[jlnorthrup122]

I'm thinking 1/4" plating on bottom and 1/8" on the rest might go with 3/16" for the rest the truss' will be made from 1/8" X 1" X 1" square tubing with gusetplates in each corner. I was considering running an old school trick on her Youremember the old hydro's with the sponsons that filled up with water when they sat in the water and when they took off the weight of the water held the nose down and as momentum picked up the sponsons would drain out the back? I am thinking about incorperating that concept into the first step on this hull design. of coarse the inletoulet opening would be on the bottom verses on the side like the old hydro's. well cool hoss thank you for your input I will check into the micro balloon cool.

[beyondhelpin]

I have used micro ballons on the outside of an engine cowling for an airplane before and as far as I know they are still on there. Done right they should be fine.

[HOSS]

Some people referr to it as micro bubble. Any yacht or sailboat builder should be using this so I would start with them and find out he vendor they deal with. I`ve never been involved in boat racing but 1/8 seems awfully thin. I am wondering what Eagle(I believe thats right) uses on their hulls. I`m anxious to know. My aluminum experience is with larger work/military hulls. Everything was 3/8. Keel being 1". Used alot of I beam and bulb tee (or some people ball tee). I can assure you though I do not have CAD experience like you nor the engineering background. But you got me interested!
I`m gonna shut up now and watch. Its quite possible I`ll retain some of what I learn. We`ll see.

[jlnorthrup122]

Here is a 3D plan I drew up on autocadd of an 18' cat I drew up 2 years ago.

[jlnorthrup122]

Here is some pics of the paint design I plan on using. The main hull color will be a transperent candy apple green over high mirror finnished aluminum and the flames will be High mirror (chrome) and will apear to be shooting up from under the water when trolling or sittin. I do have a speacial etching chem to bond the paint and clear to the high mirror finnish. I will get some truss construction pics up when I get a chance to take them now that I got my putter fixed. this machine was runnin backwards for 2 weeks so I tried to tune it up and everything but it didn't work so I went to Start/programs/accesories/systemtools/systeminfo/toolsin toolbar and enternet explorer repair and walah this ****in cable shit is worth the extra $20 a month (over phone line modem net) :)

[jlnorthrup122]

Now that cat rocks. I see taht they are running surfacedrives Is the transom 45 degrees? YOu need to 45 the transom with srface drives so You don't counteract your reverse thrust off the transom. I really like the old wooden cruiser in the background of this pic to looks like an old Chris craft Enclosed flybridge cruiser I want one of those old crusers.

[HOSS]

Anyone got a spare mill? I love that boat. Too bad I`m a broke dick ****.

[jlnorthrup122]

I bet you they built that ****er rite on that trailer that it is sittin on!

[HOSS]

Looks just like the trailers for the MK-V`s.

[jlnorthrup122]

[jlnorthrup122]

What kinda power would you put in that hoss? :cool:

[jlnorthrup122]

Looks just like the trailers for the MK-V`s. I am probly wrong but I think I had a MK-5 Really stout boat powered by superbee 440's Probly way off. it was a 1975 though so probly wrong

[HOSS]

Yeah MK-V is a Navy boat.
That boat could only be turbine powerred!

[jlnorthrup122]

She sure does have some nice lines kinda looks like a phantom paint her all black and run it at night theyed never see you coming but they would definatly hear yah though. That could be the PT boat of today you know throw some torpedos on Her mount a few 50 cals a canon or 2 hell yah a stealth pt boat build her out of titainium AHR AHR AHR :)

[jlnorthrup122]

Well I know things are running way behind schedual but I started the first construction steps on this hull today at exactly 3:30PM Central time Today!!!!! I will take some pics tomarow!!!!!!!!
I have been contemplating some changes. For one I am changing the primary hull color to transperent orange. second I am going with 1/4 canopies in place of the current windscreen in these pics due to visability reasons for got how I hate looking at window frames when I am in route! I have a conection to custom make the canopies using a vacume form by placing lexan that has been thurmal treated(heeted) I am cosidering an orange tinted lexan for the material! also I am working on an asotiat of mine who wants a 20' v bottom I want to bump it up to 24' and then start the drawings! things are really looking good rite now! Holealueya!!!
Also cosidering a third sponson in the tunnel but I can install that after I test it in the water without!(the woulders of aluminum!!!)
I have to give a huge thanks to Jeff Heno (prospective V customer my new supervisor) and Sign productions of Cedar Rapids Iowa for all the resources and conections!!!!!
I have been considering my own boat manufacturing business for years now and am closer than ever to getting there. will keep my current job and build boats on my time! This is the name of the boat company "Drifter powerboats" I have real cool logo for that.
So check back tomarow night for some pics!!

[HOSS]

Glad to here that your business is getting off the ground. Any chance of you selling me one at cost? You know for pumping up your ego and all. :D
How many people you got working on them? Welders? How much space you working under? 20k square? :cool:

Stay at it bro. Remember, "If it was that easy then everybody would do it.". :o

[jlnorthrup122]

Thanks hoss. I can already feel the trottle in my hand! Little tip The price of mateirials is allot less that I anticipated due to my source. kinda gettin it with a big order for another companies stock! the bigger the order the cheaper the price I think companies should invest in there own material depot and save a shitload of money! idea

[victorfb]

wow. that is one hell of a cool project you got going there. i havnt done any research on aluminium hulls, do they have a big advantage over glass? i noticed the "mig" machine with the hand held spool, would a "tig" machine help with the warpage? i assume thats the warpage that was commented on. mig will heat up the aluminium and cause that big time. ive tried it. it just so happens i baught a new "tig" machine today, so ill be making a hull soon aswell, but i was thinking more in the lines of a remote control with weedeater motor. ok so im not as big of a dreamer than you. :D i sure do hope you keep this thing going. i want to follow the progress. very interesting.

[jlnorthrup122]

I don't know if tig would have less warpage. I havent done much tiging on aluminum have tigged a shitload of stainless steel though. Tig machines are much cleaner that mig but it usually takes alot longer to lay down a weld with tig. Be very carefull with that tig make sure your ground is hooked up before you strike an arc. our distributer told me about a dude dieing of a heart attack from getting a jolt from a tig but this idiot kid held the lead to the dudes chest and triggered it and bam dude was dieing of a heartattac.
Do you have a scratch arc, footpedal or a button on the lead? :cool:

[HOSS]

Wouldn`t recommend you TIG the hull. Hell of a lot more heat with TIG. Warpage,,,,hell yeah.

[jlnorthrup122]

Hes talkin about an RC hull so if he runs like 1/8 inch and is fast he'll be ok tigging I think. just take your time tig in 1 inch streches and let it cool in between welds and watch the warpage you can counter act the warpage with warpage to corect this. Also when you put your reciver in an aluminum hull put a rubber gasket between the reciever and the hull or it will vibrate and be useless!!

[jlnorthrup122]

also on tig rig you can control your heat easier with voltage over mig! But you can control your heat with speed with mig rigs over tigs!

[victorfb]

i am disabled and cannot use my feet, so i bought the thump control that attaches to the trigger/wand.
one thing ive learned that you can get some of the warpage back out if you heat it and then place a cool wet rag and shrink the metal back up. it actually works well on auto body stuff. not sure about aluminium yet.
i know that tig gets very hot, but like the other post says. if you take your time and do small welds and let it cool it seems to work pretty good. though ive only done that with mig so far. still havnt tried the tig machine as of yet. im gettin ancy.... :D

[jlnorthrup122]

have fun with the filler rods! just take your time you'll be fine! :)

bumped for sidewound!! This cat will be on the waters next summer!! hope to have the hull finnished by this fall!

[jlnorthrup122]

Bump hey I got 3 truss' done so far! getting a system down to save time and build the truss' quicker! :cool:
How is it put corectly "truss' or trusses"?

Damn, I havent ever seen such encouraging words out of HOSS, EVER :D You know you are doing something right !!! Looks great so far, what you are doing 99% of the people on this board could dream of ever trying, building a new boat out of aluminum. Much respect from over here !!

[jlnorthrup122]

Thank you Very much Hallet19 I apricieate your encouragement and Your encouragement only makes me plug harder on getting her afloat thanks! These truss' are not realy structural but will add to the strenth of the hull. there primary use is to help form the hull. The 1/4" plating (skin) on the bottom and sides will be the primary structure! that shoud be strong enough to prevent the boat from buckling in extream situations such as rough water at high speeds or (hopefully never happen) colition.
Thanks Hallet19 :)
