Lightweight hull manufacturers

Charles,
Using honeycomb is not a very good idea on an infusion process. The honeycomb will fill with resin, therefore, making the part very heavy and weak. XFT hulls are most likely made using divynicell as a core material. Also, don't believe that a fifty pound hull is even close to strong and will last more than a season. I have built a couple of forty-eight pound hulls using prepreg, and they are definetaly a one season hull. I am confident that you can't build a lighter hull than that. Using prepreg cloth that is 4.3 oz and has a 38% resin content, with a layup schedule of 2-core-2, using 1/4" honeycomb, and two pound foam, and very light plumbling get's you to a forty-eight pound hull. A hull can not be built any lighter, can it? If so, I am very curious to know how. So the question is, are the advertised weights that the other manufacturer's are using for REAL? Mine are, I promise. Just my two cents.

XFT hulls are "most likely made", why would you be making claims about other companies you can't back up?

We have already been down the Honey Comb route for Pre-Preg and found it to be near usless in the marine environment, we are talking "Nomex" the type commonly used in F1. There are core materials out there that are far better at resisting the slamming loads and possible water ingression issues that are common with watercraft.

I hear Trinity is making a new SXR Freestyle hood and a new hull (probably a lot like Malone's since they apparantly designed it). I hear it is being set up for SXR parts, however. I am very interested in the hood right now. My SXR is ready to be Surf abused, but is too heavy. Most of that is from the hood (32 pounds). If Trinity can make an affordable, strong light SXR hood that keeps out water, it will make my ski much more Freestyle Ready. :woot:Blowsion's Rapter hood is pretty cool, but it is $1,100 bucks. That is wayyy too much cabbage for my blood.

It's widespread knowldege that XFT is using the divynicell, so Jeff really wasn't going out on a limb there.

I'm not sure what wet layup means, but if it's not prepreg then it's a "wet" layup. I think Riverrat just misspoke himself, trying to say it was the best combination for him (price and durability and weight considered). Obviously you can't get stronger on a per weight basis than prepreg, because it has the ideal amount of resin and it's perfectly distributed. But the cost is $$$ :bigeyes:

XFT offers a nomex honeycomb option along with the less expensive, heavier divynicell core.:biggthumpup: Also, I believe they use honeycomb core in making helicopter blades.(sound like good stuff to me)

Also, Infusion is a DRY layup, Everything gets laid up dry, then after the vaccum is applied, resin is then(for lack of better words) injected into the layup, thus only absorbing only what is needed(while under full vaccum). I've done some infusing myself, and it far excells regular bagging, and saves the outrageous costs on pre-preg.

I'd still consider that a wet layup because the resin comes in as a liquid (liquid = wet, I'm saying). Also I don't see why you would necessarily end up with more resin in a wet-then-bagged part, if you use the same vacuum that you use in the infusion process. You'd have to work to get the excess resin out of course, but it'll come out as long as it remains wet, right?

The chances of getting a bag on first try with no leaks is slim to none. I've seen some people bag parts with a small leak, but as long as they are pulling 20-24 Hg they are ok with that. At least when you infuse, you get as long as you need to find and fix leaks without racing the clock. I myself don't pull resin untill 29hg is reached thus building a tighter part(less resin). Also, when you bag with a core, it's a 3 step process, kind of like throwing money out the window. Have you ever infused or bagged? and no, it wouldn't be a wet layup, it's DRY
 
We've been quiet about this until now. We been having awesome results with the TKO Hulls. We have the TKO Hulls which are hand made in Brazil and finished in the states. I’m proud to say we’ve made a very good product. Our hulls aren’t the lightest or come with pretty carbon fiber everywhere but all around ski. I hope to have a couple TKO Hulls set up at the Daytona Freeride event for you guys to check out for yourself and compare them.

So what do they got going for them?

WHat are some estimated weights? Prices? Any special features?
In other words, what would steer a potential buyer towards a TKO hull vs other hulls?
