The opacity has nothing to do with either quality or strength.

Tell these guys then:

Amen!

Why? They agree with me that only failed (cracked and broken)
fiberglass will have less transparency than good, strong, unbroken
fiberglass. When the fibers break, they expose unwetted glass, which
is translucent.


He's right, Bob. And all this proves that my thin 35s5 hull may be a
good deal tougher than Mooron's 3/4" hull, though probably less tough
than those radomes.

Your hull is as strong as jet turbine blades. In fact, only one substance
known to man is tougher.

Amen!

I can see daylight through the hull of just about any glass hull,
dopey...

Nope! No light thru my old Catalina 30. No light thru my neighbor's Cal 30.

Bull....I owned a Catalina 27 for 5 seasons, and worked an an 88'
Catalina 30 last summer. I could see daylight with either, especially
in the aft sections. Same deal on the old Cal 29 that's parked right
next to me. And same deal for a Sweden 39 I put a new head in last
season.
Doesn't matter. Light coming through does not mean the material is
poor, weak and so on...especially if light transmission is uniform
across the area.

If you could see thru it, it wouldn't be stealth technology,
would it??

Maybe. The stuff I'm used to reflects a certain % of incident radar waves. We
put a screen 1/4 wavelength inside that reflects the same (1/2 wave total). The
two cancel in the radar's reciever.

Which come apart with great regularity ... like it they hit a bird.

Why, did you sit on it and break it?

OK, Y'all, here's the physics. The fiberglass fibers would be nearly
clear if they were not small enough to scatter light. Imbedding them
in a matrix of resin that has an index of refraction close to that of
the glass reduces the scatter and makes it seem more transparent.
"Opaqueness" of some hulls is most likely due to excessive scatter from
impefections in the resin. Thus, you might expect a very well built
hull to be nearly transparent except for some tinting due to absorption
of color.
This makes me wonder if it might be possible to make a hull bottom
nearly transparent.
