An update, http://speedonthewater.com/new-boats...ay-up-underway.

Can someone with some knowledge give us the history of progress of boat lay ups over the years with there advantages. It sounds like some new fancy terms but what's the difference? I would like a lesson. I get how wood and aluminum work LOL.

One difference between infusion and vacuum-bagging, and I am by no means a lamination expert, is that in vacuum-bagging all materials "go into the bag" together and then the excess resin or epoxy is sucked out via vacuum. As I understand, in infusion the dry materials go in first and then the epoxy or resin is pumped into the bag and them mated to the material through creating a vacuum (i.e. suction). The key difference is that the process gives the laminator better control of the amount of wet material applied in the first place and that because of the that control there is very little excess resin to "vacuum out" when the process is complete. Greater control of the amount of resin or epoxy from the start is the goal.

That's how Eric Glasser at Midnight Express, which uses vacuum infusion, explained it to me at least.

Based on the horrendous quality of the 45' Cigarette knock off they had at the boat show i'm not sure I would be taking advice from him...

Can't wait to see the Mystic finished any idea what they think the hull will weigh?

I can't speak to that because frankly I have no idea what you're talking about, but Mr. Glasser's description of the process matched with what I have been told before about the basics of how infusion works.

In a nut shell that is it. It gives greater ratio control and almost no waste. It does have its drawbacks in that a tightly pulled laminate can print and distort but these problems generally plague production style builds. I would feel very certain at this level it is the latest state of the art (possibly double bagging?) in resin/laminate control. It yields vastly higher properties. Cant wait to see it, those guys are the best in the biz and always breaking new ground.

Thanks, Dave. I was hoping you'd chime in.

Yep,
I was up last week, it's really a cool process, the 40 is going to be bad a$$, like it's big sister.

Doesnt seem that difficult

Crazy!
