This page talks about the use of two aluminum plates
to sister a delaminated main beam in the older Alberg 30's.
There are other techniques that have been used to fix this
problem. This technique was developed by Bruce Rankin and
had proved to be simple and durable
See the collaboration section and mailing list archives for other perspectives.
The plates should be 3/8" thick 6061 grade aluminum, cut to fit
the curve of the beam.
Rather than starting with drawing your own templates for the aluminum,
you can contact one of these companies which have already digitized the
shape. These companies use a water-jet cutting process that results in
a very clean cut.

This Old Boat
by Don Casey
Subtitled "turn a rundown fiberglass boat into a
first-class yacht on a shoestring budget," this book is the best
introduction I know boat maintenance for the new or prospective owner
of a "modern classic" sailboat. Starting with guidelines
for selecting a boat, Casey proceeds to fiberglass repairs, cabin and
deckwork, spars and rigging, boat equipment, woodwork, electrical,
plumbing, refrigeration, painting, canvas work and sails. All of this
is described in clear, simple terms perfect for the inexperienced.
This is the book that taught me fiberglass work. But don't let it
fool you; this book is appropriate for experienced boatowners, too.
I still refer to it.
