Custom/Hybrid Cost in materials for a carbon hull?

[Waternut]

You guys are going to think I'm nuts but I'm used to it...lol. I like the way my hull rides so much that I'm considering making a mold from it and replacing it with a carbon version of the hull this winter.

Ignore mold costs right now for simplicity. I know cost of materials varies but what is a realistic estimate in materials to build a hull out of carbon?

go nut go !!!!!


I dont have an answer to your question , , but I cant wait to see what you come up with

You really haven't given us enough info for anyone to answer your question, answer the following questions and you will be a lot closer to your answer.

Are you using any type of core material or will it be solid carbon fiber ?

Are you using Epoxy resin or vinyl ester resin ?

How strong vs light are you wanting this hull to be ?

Flatwater use only or will it be used in surf ?

:cool2:

i would say $900.00 to $1200.00 in carbon

oh great, more stunt hull molds........uh 3000.00?:cool2:

Well just to clear up any hate....this thing is as much of a stunt hull as a rickter is a RN.

The plan is actually to use solid laminate and epoxy resin. It will be used 95% flatwater. My main purpose in creating this thread was to determine if it would be closer to $1000, $2000, or $3000. If it's around $1000, it may be worth doing. If it's going to exceed $2k in carbon fiber and resin, it's probably not worth doing since I have no real intention of selling them unless people start asking for them (which I doubt).

I would say by the time you buy the materials for the molds you are looking at spending around $2000.00, a lot of people tend to forget to add in all the throwaway items, boxes of brushes, fiberglass rollers,gloves, tyvec suits, rolls of plastic to contain the resin spillage, mixing sticks , buckets and if you are making molds you have to have some kind of framework either wood or steel to support the molds, screws to put it all together wit etc etc.

I appreciate the insight. I was estimating roughly another $1000-$1500 on top of carbon and resin costs for making the molds, vacuum bagging expendables, hardware to mount everything to the hull, gloves, brushes, etc.

Obviously, this whole thing is still on the drawing board so any other thoughts, considerations, and criticisms are more than welcome. I'm a noob to large scale mold and hull making but I am a structural engineer by trade so please don't put me on the same level as the original manufacturer of this hull.

i work with engineers everyday on huge building projects. can't give you any credit on that one either bro. text book education means nothing without real life experience.

I don't really care what you will or won't give me credit for...that's not why I'm here. I'm just asking for input without the ever popular "you don't know what you're talking about" statement from people who don't know what they're talking about.

Just wanted to say I am in no way, shape, form or fashion saying don't do it

cost - a lot :cool2:

doing it right, in the end, your going to drop as much coin as it would be to buy an aftermarket hull (not including the time/labor).

+ material for vacuumbagging!!!

Didn't you do this yourself with your Rickter? Surely you didn't spend as much on making a new hull as you would've to buy a brand new hull....

plus you get the gratification that you built it your self the way you wanted it . You have chopped and modified enough to know what you want in a hull. I think it will be way more worth it to you than the cost of the build. dont listen to the haters .

i am just saying that being an engineer won't make you a hull builder or a composite expert. now do what you want. if you want to spend alot of money to loose a few pounds making a carbon copy of a crappy hull go ahead. the learning curve and time will be priceless.

you're an engineer, price it yourself.

cy of cloth * # of layers * (expected waste % + 100) * cost of carbon cloth
once you know the amount of carbon you can figure the amount of resin.

similar equation for molds but double the layers and lower the cost of the cloth

plus materials



it won't be cheap.

hating on the idea to carbon copy a hull that was a fail. yep, guilty. apparently the diploma on the wall didn't come with any practical knowledge. If waternut is going to spend the time and a decent investment on making a mold, then do you think the stunt hull is the best to start with for the plug? Okay maybe i am waaaaay off here but starting with a superjet hull that has no fitment issues would be a better idea, then take what ever options one likes about these new hulls and apply that to the hull and make it his own. he will never sell a carbon copy of a stunt hull and do we really want to see someone buy one from an amature hull builder? someone needs to be the hater on this so the idea never goes to production. save this guy some money people and from loosing friends if he decided to try and sell this crap.
