my waterdawg vacation!

[Idok]

then tell your friends. :Banane01:

to throw rocks at you? :haha:

 

[SkiNaked]

I understand trying to make affordable skis. But using Home Depot PVC and hose for exhaust and cooling??? eeek. Not the highest quality.

Quality looks in line with some of the C.A.T.S. posts.

You guys are killing me :skull2: :cool2: I don't think he is using PVC

CPVC(Chlorinated Polyvinyl Chloride) conforming to ASTM D-1784 Class 23447-B, formerly designated Type IV, Grade 1, CPVC has physical properties at 73°F similar to those of PVC, and its chemical resistance is similar to that of PVC. CPVC, with a design stress of 2,000 PSI and maximum service temperature of 210°F has, over a period of about 25 years, proven to be an excellent material for hot corrosive liquids, hot and cold water distribution and similar applications above the temperature range of PVC. CPVC is joined by solvent cementing, threading or flanging.

It will do the job just fine. I know that metals have a tendency to "sweat" and water can condense on the outside of them which is why when you defoam your boat you will notice that the foam can be a little wet, though it is usually not that bad.

The flexable braided line is about the same story. I bet it will out last the boat itself depending on how you ride. I would expect it to last anywhere from 10-15 years. They use that suff on refigerators, which can subject it to more extremet temps and there does not seem to be a problem there either. I am sure that if you want a different type of tubing he will do whatever you want.

The piping in the photos posted in this thread IS NOT PVC or CPVC.

It's ABS---look up the ASTM ratings on ABS pipe and tell me how well it will hold up to temps from an exhaust.

 

[RoyalFlush@PCB]

Welcome back.

Oh yeah---Welcome Back, Rat!!! :arms:

 

[RiverRat]

if it is ABS it sounds even better:

According to studies performed by the ABS Institute, ABS pipe was shown to be unaffected by commonly used household chemicals - including drain and bowl cleaners, such as:
Tide detergent
Soilax cleanser
Borax cleaners
Calgon water softener
Ammonia 5% solution
Renuzit spot remover
Drano
Liquid Sani-flush
Liquid Plumber
Lysol bowl cleaner
Vanish bowl cleaner
Liquid Vanish bowl cleaner
Sno-Bol bowl cleaner
FIRE-RATED CONSTRUCTION
When properly installed in compliance with building and fire codes, ABS can be used in fire-rated construction, such as high-rise dwellings. Schedule 40 ABS DWV systems are suitable for fire-rated wall, floor and ceiling assemblies.
ABS pipe must be heated to over 871°F (465°C) before it will self-ignite. In comparison, the types of wood commonly used in home framing self-ignite around 500F (260°C). In an out-of-control fire, temperatures reach well over 1,000F (540°C), at which point all combustibles burn.

I will call him at some point and get some specifics on what he is using.

 

[RoyalFlush@PCB]

It's ABS---look up the ASTM ratings on ABS pipe and tell me how well it will hold up to temps from an exhaust.

I just did a quick search and found that the ABS piping is rated to 180 degrees, so it's not as bad as I thought. :smile:

I still say that a metal piping would be the better choice, here. :cool2:

 

[RoyalFlush@PCB]

I Googled that Website, as well. Don't be confused by the fire-rating mumbo-jumbo, that just says the temps at which it will ignite. :bigeyes:

 

[djkorn1]

I am sure that it will hold up fine. Nitpickers.... That is a bad ass hull.

BTW... Riverrat! Good to see ya back. :Banane01::woot::cheer:

 

[RiverRat]

Got some anwsers:

Ok, got off the phone with him and he is using a high temp ABS that is rated to about 240 degrees. Regular PVC is rated to about 140 degrees. He has never had a failure on any of his boats, one even had a cooling line come off and pretty much cook the motor. The ABS is also very light so that is a plus. If you want aluminum tubing he can do that as well. He has a mandrel bender and can weld it all up reall nice but it will add about $300 to the price of the boat. The only real benifit is peice of mind for the owner, it is whatever you want.

The braided water line is very durable as well. Very hard, high chemical resistance ect.... I do not have the specs on that stuff but it is not going to rot on you or anything like that. If you ever did have a problem it would be way down the line, like 15+ years. If you want metal line I am sure he can do that also.

The hull is not all chopper, it is a combination of chopper and hand laid glass. If ordering a hull from him just ask him the how's and why's and he will give you all that info.

Keep in mind also that this hull is being built on a budget. It is still a kick ass hull for sure :biggthumpup: It should be in Daytona so you can see it in person if the owner is in attendence. Nice build! Keep it comming :skull2:

I Googled that Website, as well. Don't be confused by the fire-rating mumbo-jumbo, that just says the temps at which it will ignite. :bigeyes:

I was just looking for any info on ABS and temp ratings. I guess temp resistance info or operating temperature specs would have been more applicable

Chopper gun layup.
PVC pipe for exhaust
Rubber tube for cooling lines.

Starting to see why Waterdawg sells these things so cheap. I guess you really do get what you pay for! Looking at the internals of the X-Jet or REV (or what ever you call them these days) is nowhere close to some of the other aftermarket hulls I have seen.

If I were jeff I would ask you to remove those picture. They are not good for marketing the Ski!

Here is what I would expect the inside to look like.

i see rubber hoses in the drains of that $10k plus hull, they can rot and leak water into the foam, lets see the inside of other hulls. I bet for the extra 6.5k, Jeff could build something nicer than that. You can test pilot this ski from your computer all you want, but you just don't know.
The point is, Jeff can build (not just import) any type of hull you want, you aren't limited to the same choices.

btw, I've had experience with the german hull. it is a very nice hull and its better than other handlaid glass hulls i've seen, but Jeff's prepreg hull quality is the top I've seen.

 

[Mile9c1]

Here is what I would expect the inside to look like.

Actually to me that looks like someone rolled up $5,000 and smoked it. Bye bye money, I don't care that I got nothing for you! :biggthumpup:

No one is even in the same playing field as Norbert, his hulls are Ferraris. Waterdawg has a long way to go to compete with him in the composite side of the industry.

Well looking at this from the practical side... Norbert has a LOOOONG way to go to catch up to Jeff in the freestyle hull business. And he will never get there! Norbert has a NICE wet laid up carbon sandwich Superjet copy for $10,000 (insert sarcastic party emoticon here). Jeff has F1-Pro, X-Jet, Rev, entry level, mid level, any level you want, build it yourself, totally custom, or TOP OF THE LINE prepreg technology if you want the nicest hull out there. Oh, and any color you want if you don't like flat black :woot:

You guys will never give up, will you? All we need now is for Sub to show up and tell everyone how Jeff works out of his garage

 

[Mile9c1]

lets see the inside of other hulls

Why don't we just ask whoever has a Lightweight hull and a REV1200 to give us his thoughts? :biggrin:

 

[Mile9c1]

I'm not too sure about the plastic exhaust, but as long as it doesn't melt and it stays together at the joints, I don't have a problem with it. No need to waste money just to waste it.

The braided cooling water lines... I like them a lot, I wouldn't do it any other way. The hoses will last forever, and you can't pull them out on accident! They will not leak; the fittings are barbed and on top of that the hoses are clamped to them.

Chopper gun... for $3,500 and a strong light hull, Jeff could make it out of bubblegum for all I care as long as it holds up :hail: And I believe Jeff knows more than anyone on this board how it will hold up.

 

[RiverRat]

Also a carbon exhaust tube is not the way to go IMO. Finding a high heat resistant resin and a high chemical resistant resin would be difficult. That stuff can break down then you are SOL. If you want that peice of mind do the aluminum for an extra $300. Carbon is very expensive and not the best material for the job IMO. Scupper tubes I am sure it works well.

Does anyone know what type of resin they use on the carbon b-pipes?

 

[WaveDemon]

who is norbert?

 

[RiverRat]

flacarandcycleguy what was your impression of the 1200cc vs that 5mm lamey stroker in that all prepreg REV hull (red ski)?

 

[RiverRat]

who is norbert?

I think he is taking about the carbon hull from Germany
