Wavy Fiberglass boats?
 

Just a question! If anyone takes this as an opportunity to slam ANY boat manufacturer.. I'll poof it.:)


At the Miami show last week, I was wondering why some boats were perfectly straight down the sides and some were wavy. Why?

Is it because of the mold...materials used... workmanship...not enough sanding?

My inquiring mind would like to know..That's all:)

As I understand it, you can also get a wavy hull by pulling it from the mold before everything has fully cured.

Craig.....from what I could tell, the hulls you saw in the morning were wavy while the hulls you saw in the afternonn looked straight. :D :D :D :D In some cases, they were the same hulls.

Craig, you should not have started drinking at breakfast. Every boat I saw at the show was perfect.

Hmm, maybe that is because I spent so much time staring, er, drooling over the Dragon.

Actually all of these factors can contribute to a wavy hull:
-materials used (resins, mat, gel vs paint...)
-layup (thickness)
-cure time
-mold quality
-structual layout
-workmanship
-finishing quality

And probably a couple other items I've forgotten about.

I have heard:
Pulling from a mold that is not well maintained too fast.

Not trying to slam, but for example:
Donzi's FG is very wavy, where Sunsation is smooth.
High volume prodcution MFG vs. low production MFG??

I usually just wave back at them while I'm walking away.

I know the Platinum boat that I saw in Milwaukee was laser straight. Not a wave or wrinkle in it. But, I believe those molds were cut on a CNC so they should be perfect.

Thanks for the responses (except from Norty and Brian:D :D ).

I think they are "autoclaved" also... put in an oven at 180 degrees for a day or two.. cures them out fast...
