There have been products around since the 1950's which are good for
treating planking but may not have the stength for ribs and beams. However
you can always build in structural reinforcement with glass fibre, metal,
wood, plywood, or some combination and have a repair which is stonger,
more rot resistent, and more durable than the original. For example you
can cut out the rot, drill holes, insert metal rods, and build up with
resin or in some cases cement mortar. It all depends on what parts you
need to repair. Watch the weight when replacing wood with non-wood
substitutes.
