I see Beneteau recalled the furler on the first few years of 35s5. It
seems it was the Isofurl. Has yours been changed?

Another great reason to buy a boat from an active builder. Gave
Beneteau the hull number and they reported all warranty work done,
including the furler changout in 1996.

That is nice.

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.

As the numbers of resin/glass interfaces goes up, the scatter goes up
because of the slight diff in index of refraction between glass and
resin. I wonder if proper choice of glass or resin (so as to match
indices of refraction) could make a transparent (rather than
translucent) hull.

That, plus a 41 layer AR coating done in a giant chamber for optimum
uniformity.
I'll whip one up for ya. :-)
