Once again... I'd suggest you research the material before you make
comments. You may believe it, but the data doesn't support your beliefs.

Some foam is good as structure, some is so scored for flexing

"fiberglass planking" among some) is intended to be torn out
after serving as shape form. It is not intended to be used a
structural ingredient.

Right , maby they are and maby there are several different way's to produce a
glasfiber boat . But if you don't want to spend your time sanding and filling ,
sanding and filling, sanding and filling, ------ and then spend a lot of money
on special paint and coatings and then sand and paint with expensive paint,
then you could consider to find panels with one side ready and place that side
as the outside.
Several workshops acturly produce glasfiber laminate for different porpus, like
sthe sides of huge trucks or camping wagons , what do you think they are made
of.
Well years ago I found a factory in denmark , that was glad to sell the truck
side panels they produced for their own trucks, and this was 2 millimeter
glasfiber/polyester with white gelcoat. The glasfiber and polyester they used
was that used producing boats, and then you still want to panel with somthing
you need to sand and fill , paint and spend months to create the very same
surface, that you can buy for round 20 pound pr. sq. meter, to be cut directly
from full-scale plans as with the Cyber-Boat concept that was interduced before
anyone else.
What take time is the sanding and making a nice finish ; with ready made
glasfiber panels you can sand the back side and continue from the inside of the
hull with more glasfiber and resin, or you can use the panels as forms in a
reliable building jig .
Check the antike Cyber-Boat site where you among the links, can find designs
with this idear ;

Othervise there are a lot of glasfiber boats with wooden timbers, where the
glasfiber just form the skin, here the 3D-Honeycomb method develobed with the
Cyber-Boat concept can also be used providing a frame set with no trouble .

Ask yourself why to spend your money and time , sanding and painting with
expensive filler that you anyway remove 3/4 of, to get the exact same nice
surface, as when you simply find ready made panels with one nice side.
